Appucatiun med may 11, 1910. serial No. 560,635.

To all whom it may concern: l

Be it known that I, FRANK Somer, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Padlocks, of which the following is a specification.

The object of my invention is to construct a combination adlock in such a manner that the shacklewil be held at both the heel and the nose and the combination mechanism will Vbe distributed the moment the lock is closed. y

The invention relates also to ,certain details of construction which will be fully` described hereafter. y

In the accompanying drawings Figure 1,'is a perspective view of my improved combination padlock; Fig. 2, is a view of ,the lock with the rear casing removed, showing the shackle in the closed position; Fig. 3, is a view similar to Fig. 2,with the tumblers of the lock removed and the shackle open; Fig.

4, is a sectional view on the line 4-4,'Fig, 2; Fig. 5, is a detached perspective view of the shackle; Fig. 6, is a detached perspective view showing the series of tumblers and washers; Fig. 7 is a detached perspective view of the cam plate; Fig. .8, is a perspective view of the dog; Fig. 9, is' a perspective view of thelocking bolt; Fig. 10, is a perspective view .of the device for throwing the dog out of engagement with the tumblers; Fig'. 11, is a perspectiveview of the front plate; Fig'. 12, is .a perspective view of the handle; and Fig. 13, is a View illustrating `a modication of my invention.

A is the front casing of the lock and A is the rear casing, secured together by rivets or other fastenings B is the shacklemounted on a pivot pin a secured to both sections of the case and this shackle has a nose b engaged by the bolt C pivoted at c to the casing. The bolt is made in the present instance from a plate; the engaging portion c being turned at right angles lto the body portion, as shown in Fig. 9.

cured to a post a projecting from the casing,-

so that, while the tumblersare free to turn,

lthe washers are held in a fixed position.

The first tumbler has a pin g which passes through slots g inthe other tumblers and into one of the slots ein the disk E. A spring f is mounted -o'n the ivot pin al of the dog F and oneend of this spring rests against the nose of the d og and the other rests -againsta pin d on the cam plate D, tending to force the dog against the tumblers, The cam' plate D is recessed aty d2 for thepassage of a post a. v

Mounte on a post a2, secured to the casing of the lock, is a spring I, one arm z' of Which rests against the casing and the other .arm z" rests against a pin als on the cam plate D, and the spring returns the cam plate to its normal position when the dog is released,

as shown in Fig. 2. The bolt has a projec- 'Patented Nov. 29, 19101` this cam plate its spring I Will returnA it to.

its normal position and will cause the bolt to belprojected into the notch back of the nose of the shackle, as illustrated in Fig. 2. The surface s2 of the cam plate rests in front of the heel b of the shackle and locks the shackle in the closed osition, so that the shackle is doubly locke namely, at the heel and at the nose.

When the cam plate is turned in the direction of the arrow, Fig. 3, to draw the bolt from the nose of the shackle, the edge s is moved out of the path of the heel of the shackle, so that the heel' is. released at the same time as the nose, consequently, the spring k, mounted on the pivote, causes the shackle to spring open to the position shown in Fig. 3.

`Mounted on the pin n projecting from the case and through the' opening d2 in the cam plate is an arm N which is shaped to pass and force the nose of the dog F ont of engagement with the tumblers as soon as the cam plate is released. A spring n2 is attached yto this arm and bears against the post a. `When the parts are inthe locked position the do 'is on one side of the point n of the arm and when the camplate is moved by operating the handle E the dog moves past this point and the point acts as a cam to force the dog out of the notches in the tumblers, immediately releasing the plate, which springs back to its normal position, as shown in Fi 2. This movement destroys the -combination.r

I preferably secure a. plate A2 on the face of the casin as Ishown in Figs. l and 11. This plate 2 has the flange a3 which incloses the inner portion a2 of the handle, which is notched to form a part of the click mechanism. .Surrounding this ange are thecnunierals, in the present instance arranged as the dial of a clock, but it will be understood that any number of numerals may be used, or letters, or other marks may bensed in place of the numerals. There are as many notches in the surface e2 of the handle as there are numbers on the dial, and on the casing are one or more projections with which these notched portions of the handle engage, so as to bring the handle in the proper position.

one of which may be discarded, if desired.

By the above construction it will be seen that l can make a combination padlock in which the combination is destroyed as soon as the shackle is closed and locked, and that the shackle is held, not only at the nose, but

y also at the heel, making a very substantial,

and at the same time a comparatively cheap, combination lock.

vln lFig. 13, l have shown a modification of the invention in which the cam plate D', instead of being pivotally mounted, is mounted to slide in the casing, so that when it is in its raised position it will hold the bolt C in the locked position and will engage the heel of the shackle B", and when depressed will force the bolt out of engage? ment with the shackle and draw away from the heel. A

rlhe dog F is in such position 'that on the rotary movement of the tumblers the plate will be drawn down through the medium of the dog and when the plate is raised the dog will be automatically thrown out by the pivoted. arm.
