IMPROVEMENT IN MACHINES FOR RIVETING LOCK-CASES.
Specification forming part of Letters Patent N0.'128,205, dated J une 25, 1872.
or more of such rivets or parts are tightly and solidly clamped and held in the desired position while the rivets are being swaged or pressed.
In the accompanying drawing, which represents a double-action press fitted up for riveting the back of a common drawer-lock to the front part, Figure 1 is afront elevation of the said press. Fig. 2 is a side elevation of the same. Fig. 3 is a plan of the devices by which the work is held while being riveted. Fig. 4
is a view in detail of the side and one end of the lock-back. Fig. 5 is a similar detail of the front part of the frame of the lock. Fig. 6 is a View in detail of the back of a finished lock.
A is the frame of the press; B, the drivingshaft; 0, the gate, moved by cranks and the connecting-rods or pitmen D D; and E is the secondary slide, which is actuated by an independent crank or eccentric and a connection, F, to produce the double action or motion of the press. G is a bed or guide, in which the sliding block or head H is fitted. A second slide, I, is fitted in the slide H, and is operated by a lever, J. This slide I is fitted somewhat loosely, so that its forward end may have a small lateral motion, for a purpose which will hereinafter appear. The front part of the lock 6 is laid in the slot in which the slide I works, near the front end, its front edge resting against-the stops at a. The slide 1 is then brought forward into the position shown in the drawing, and a slide, K, actuated by the screw b, is forced against the vend of the lockfront 0, tightly clamping it between the stationary jaw or block L, the slide I, and the slide ormovable jaw K; the slide I yielding laterally, if necessary, to compensate for any variation in the thickness of the metal of which the lock-fronts are made. The slide I passes over the main part of the lock-front eand holds it down, while the studs or projections 0 project above the slide I to receive the lock-back f, which is placed upon them, the studs or projections 0 passing through the holes at in the back plate f. The head His then pushed back till it strikes the stop M, and the power being applied to the driving-shaft B the gate descends and forces the back-plate down snugly into its place.- The slide E then descends and swages or spreads the ends of the projections c, causing them to fill the holes d, and effectuerwise yield. It is evident that when the sides 1a are made in two separate pieces the slide I may be dispensed with, and a piece having a lateral yielding motion only be secured between the jaws K and L in any convenient way, (as, for example, by a bolt passingthrough a slotted hole in said piece,) and be used as a substitute for the slide I. It is also evident that two or more such yielding pieces may be used between the stationary and the movable jaws in cases where it is desired to hold three or more pieces or rivets.
The relative positions of the cranks or eccentrics which produce the double action of the press are clearly seen in the small dotted circles in Fig. 2.
Many other kinds and forms of articles may be riveted together in the manner hereinabove set forth, it being necessary only to apply the proper tools for holding the pieces, and suitable punches for pressing or swaging the rivets to the double-action power press.
By the employment of the method above described various articles or parts of articles may be rapidly and strongly riveted together withoutdanger of bruising, bending, or breaking, which is very liable to occur where the riveting is done by a blow; the parts are much more closely united, and the work is aceonrforth in the first clause of claim, of the recipplished at a much less cost, than it can be by rocating slide or gate 0 and slide E, substanany method heretofore in use. tially as described.
