Read novel on framework only is shown. The frame is 12" 12", and 5 feet high, and made up of 2" 2" material. When neatly framed together, it is a most attractive article of furniture. The top may be covered in any suitable way, showing a roof effect. The opening for the dial face of the clock should be at one of the gable ends.
A more pretentious bookcase is shown in Fig. 259, in which the frame is made up wholly of 2" 2" material. The cross-end bars serve as ledges to support the shelves. This may be lined interiorly and backed with suitable casing material, such as Lincrusta Walton, or fiber-board, and the front provided with doors. Our only object is to show the framework for your guidance, and merely to make suggestions as to structural forms.
[Ill.u.s.tration: _Fig. 262._]
Another most serviceable article is a case for a coal scuttle (Fig.
260). This should be made of 1-inch boards, and the size of the door, which carries the scuttle shelf, should be 12" 16" in size. From this you can readily measure the dimensions of the case itself, the exterior dimensions of which are 15" 20", so that when the 1-inch top is placed on, it will be 21 inches high. The case from front to rear is 12 inches, and the shelf above the top is 11 inches wide, and elevated 10 inches above the top of the case. This is a most useful box for culinary articles, if not needed for coal, because the ledge, used for the coal scuttle, can be used to place utensils on, and when the door is opened all the utensils are exposed to view, and are, therefore, much more accessible than if stored away in the case itself.
[Ill.u.s.tration: _Fig. 263._]
A mission armchair. Fig. 261 is more elaborate than the chair shown in Fig. 257, but it is the same in general character, and is also made of 2" 2" stock. The seat is elevated 16 inches from the floor, and the rear posts are 28 inches high. The arms are 8 inches above the seat. A chair of this character should have ample seat s.p.a.ce, so the seat is 18"
18".
The dog house (Fig. 262), made in imitation of a dwelling, is 24 inches square, and 18 inches high to the eaves of the roof. The opening in front is 8" 10", exclusive of the shaped portion of the opening.
[Ill.u.s.tration: _Fig. 264._]
[Ill.u.s.tration: _Fig. 265._]
Fig. 263 shows a simple and easily constructed settee with an under shelf. The seat is 16 inches from the floor and 24 inches wide. The back extends up 24 inches from the seat. The lower shelf is midway between the floor and seat, and is 19 inches wide. This may or may not be upholstered, dependent on the character of the material of which it is made. If upholstered, the boards may be of second-cla.s.s material, preferably of pine or other light, soft wood.
A towel rack (Fig. 264) is always a needed article in the kitchen. The roller may be an old curtain roller cut down to 18 inches in length. The top piece is 2-1/2 inches wide and 21 inches long. The vertical bars are each 1-1/2 inches wide and 9 inches long. The brackets are 1-1/2 inches wide and made of 3/4-inch material.
Fig. 265 represents the framework of a sofa, the seat of which is 16 inches high, the front posts up to the arm-rests 24 inches, and the rear posts 38 inches. From front to rear the seat is 18 inches. The posts are of 3" 3" material. This makes a very rigid article of furniture, if mortised and tenoned and properly glued. The seat is 6 feet long, but it may be lengthened or shortened to suit the position in which it is to be placed. It is a companion piece to the chair (Fig. 261).
CHAPTER XVIII
SPECIAL TOOLS AND THEIR USES
In the foregoing chapters we have referred the reader to the simple tools, but it is thought desirable to add to the information thus given, an outline of numerous special tools which have been devised and are now on the market.
BIT AND LEVEL ADJUSTER.--It is frequently necessary to bore holes at certain angles. This can be done by using a bevel square, and holding it so one limb will show the boring angle. But this is difficult to do in many cases.
[Ill.u.s.tration: _Fig. 266. Bit and Square level._]
This tool has three pairs of V slots on its back edges. The shank of the bit will lie in these slots, as shown in Fig. 266, either vertically, or at an angle of 45 degrees, and boring can be done with the utmost accuracy. It may be attached to a Carpenter"s square, thus making it an accurate plumb or level.
MITER BOXES.--The advantages of metal miter boxes is apparent, when accurate work is required.
The ill.u.s.tration, Fig. 267, shows a metal tool of this kind, in which the entire frame is in one solid casting. The saw guide uprights are clamped in tapered sockets in the swivel arm and can be adjusted to hold the saw without play, and this will also counteract a saw that runs out of true, due to improper setting or filing.
[Ill.u.s.tration: _Fig. 267. Metal Miter Box._]
A second socket in the swivel arm permits the use of a short saw or allows a much longer stroke with a standard or regular saw.
The swivel arm is provided with a tapering index pin which engages in holes placed on the under side of the base. The edge of the base is graduated in degrees, as plainly shown, and the swivel arm can be set and automatically fastened at any degree desired.
[Ill.u.s.tration: _Fig. 268. Parts of Metal Miter Box._]
The uprights, front and back are graduated in sixteenths of inches, and movable stops can be set, by means of thumb-screw to the depth of the cut desired.
Figure 268 shows the parts of the miter box, in which the numbers designate the various parts: 101 is the frame; 102 the frame board; 104 frame leg; 106 guide stock; 107 stock guide clamp; 109 stock guide plate; 110 swivel arm; 111 swivel arm bushing; 112 swivel bushing screw; 113 index clamping lever; 115 index clamping lever catch; 116 index clamping lever spring; 122 swivel complete; 123 T-base; 124-1/2 uprights; 126 saw guide cap; 127 saw guide cap plate; 132 saw guide tie bar; 133 left saw guide stop and screw; 134 right side guide stop and screw; 135 saw guide stop spring; 136 saw guide cylinder; 137 saw guide cylinder plate; 138 trip lever (back); 139 trip lever (front); 141 leveling screw; 142 trip clamp and screw; 146 T-base clamp screw.
[Ill.u.s.tration: _Fig. 269. Angle Dividers._]
ANGLE DIVIDERS.--This is another tool, which does not cost much and is of great service to the carpenter in fitting moldings where they are applied at odd angles.
To lay out the cut with an ordinary bevel necessitates the use of dividers and a second handling of the bevel, making three operations.
THE "ODD JOB" TOOL.--A most useful special tool, which combines in its make-up a level, plumb try-square, miter-square, bevel, scratch awl, depth gage, marking gage, miter gage, beam compa.s.s, and a one-foot rule.
To the boy who wishes to economize in the purchase of tools this is an article which should be obtained.
[Ill.u.s.tration: _Fig. 270. "Odd Job" Tool._]
Figure 270 shows the simplicity of the tool, and how it is applied in use.
BIT BRACES.--These tools are now made with so many improved features that there is really no excuse for getting poor tools.
The ill.u.s.trations show merely the heads and the lower operating parts of the tools. Fig. 271 shows a metal-clad ball-bearing head, so called, as its under side is completely encased in metal securely screwed to the wood and revolving against the ball thrust bearing.
D represents a concealed ratchet in which the cam ring governs the ratchet, and, being in line with the bit, makes it more convenient in handling than when it is at right angles. The ratchet parts are entirely enclosed, thus keeping out moisture and dirt, retaining lubrication and protecting the users" hands.
The ratchet mechanism is interchangeable, and may be taken apart by removing one screw. The two-piece clutch, which is drop forged, is backed by a very strong spring, insuring a secure lock. When locked, ten teeth are in engagement, while five are employed while working at a ratchet. It has universal jaws (G) for both wood and metal workers.
In Fig. 272, B represents a regular ball bearing head, with the wood screw on the large spindle and three small screws to prevent its working loose. This also has a ball thrust. E is the ratchet box, and this shows the gear teeth cut on the extra heavy spindle, and encased, so that the user"s hands are protected from the teeth.
The interlocking jaws (H), which are best for taper shanks, hold up to No. 2 Clark"s expansion, and are therefore particularly adapted for carpenter"s use.
[Ill.u.s.tration: _Fig. 271. Fig. 272. Fig. 273. Types of Bit Braces._]
In Fig. 273 the plain bearing head (C) has no ball thrust. The head is screwed on the spindle and held from turning off by two small screws.
The open ratchet (F) shows the gear pinned to the spindle and exposed.
This has alligator jaws (J), and will hold all ordinary size taper shank bits, also small and medium round shank bits or drills.
[Ill.u.s.tration: _Fig. 274. Fig. 275. Fig. 276. Steel Frame Breast Drills._]
STEEL FRAME BREAST DRILL.--These drills are made with both single and double speed, each speed having three varieties of jaws. The single speed is very high, the ratio being 4-1/2 to 1, which makes it desirable to use for small drills, or for use in wood.
A level is firmly set in the frames of these tools to a.s.sist the user to maintain a horizontal position in boring. Each of the forms shown has a ball thrust bearing between the pinion and frame. The breast plate may be adjusted to suit and is locked by a set screw. The spindle is kept from turning while changing drills, by means of the latch mounted on the frame, and readily engaging with the pinion. The crank is pierced in three places so that the handle can be set for three different sweeps, depending on the character of the work.
Figure 274 has a three jaw chuck, and has only single speed. Figure 275 has an interlocking jaw, and is provided with double speed gearing.
Figure 276 has a universal jaw, and double speed.
PLANES.--The most serviceable planes are made in iron, and it might be well to show a few of the most important, to bring out the manner employed to make the adjustments of the bits.
