PATENT LOCK.

SPECIFICATION forming part of Letters Patent No. 271,662, dated February 6, 1883,

Application filed March 23, 1882. Renewed November 23, 1882. (Model.) i

Be it known that I, SOLOMON P. STODDARD,

i of the city, county, and State of New York,

have invented an Improvement inLoclis, of which the. following is a full, clear, and exact description, reference heilig had tothe accompanying drawings, forming partof this specification.

My invention relates to a lock in which th bolt-piece is constituted and arranged in two or more sections orparts,which,when the bolt is shot, are protracted sidewise, thus causing the bolt end to become spread; and my invention consists in the devices hereinafter specified, and combined to operate as and for the purpose described. Figure l is a side view ofa lock containing my invention, the bolt being shown retracted and the side plate removed. FigV 2 is a similar view of the same, the bolt being shown shotanditssectionsprotractedsidewise. Figs. 3 and 4 are side views, in detail, of the sections constituting the bolt-piece detached from the boltplate.

In the drawings I have shown a lock the actuating mechanism ot'which is fully described and claimed by me in Letters Patent of the United States No. 254,402, dated February 28, 1852, consisting substantially in the tumblers A, the boltplate B, carrying the rack b, and the operating-pinion C, with its peculiar keyslot c, the several parts being combined orarranged relatively to each other in the manner therein recited. It is not necessary', therefore, in this specification to do more than naine the parts of this actuating mechanism, and to refer to the aforesaid patent for a more full description thereof. Moreover, I do'not intend to limit myself' herein to the specific actuating mechanism shown, as my improvement is capable of use in connection with other kinds ot' lock mechanism.

My improvement consists in the bolt-piece D, which I form in two or more sections, d d, coincident in general form and outline, and imposed oue upon another, as shown. When thus arranged they are of substantially equal width with the width of thebo1t-plateB,andin thickness they are adapted to enter and traverse freely through the bolt-slot in the face-plate of the lock-case. The several sections of the thereof.

' bolt-piece are pivoted by a pin, d', which is common to all the sections, to the forward end of the bolt-plate, so that the sections are capable of swinging edgewise on said pivot. In u each of the sections ofthe bolt-piece is cut the longitudinal slot d2, whichextends in a right line from a point adjacent to the forward end of the section to near the rearward end of the section, where the slot is inclined or carried at an angle to one side of said line, forming acurved oroblique heel portion, da, to the slot, as seen plainly in Fig. 3. These portions 'd3 of the slots d are carried or turned alternately to one side and the other ofthe median line ofthe slots in the several sections of the bolt-piece-that is to say, the portion clgof the slot of the upper section of the bolt-piece being inclined to the' right, the portion la of the slot of the section underneath is inclined in the opposite direction,'or to the left, and so on throughout the sections. These slots cl2 throughout their extent are adapted to receive a pin, d, which is tixed in the interior face of the lock-case, and which projects therefrom through the several sections of the bolt-piece.

rIhis pin d4 is set inthe look-case so that the position of its projecting end relativelyv to the slots d2 will be such that when the bolt is retracted the pin will lie in the forward end of the slots, as seen in Fig. l, and when the bolt is shot the pin will rest snugly against theinclosing-edges of the slots in the portion di In the drawings I have shown a holt-piece composed of two sections; butitis evident that more than two sections may be employed to make up the bolt-piece without materially altering the essential features of my invention. Now, it is evident that when the bolt is retracted the sections ofthe bolt-piece will rest coincidently one upon the otherwithin the case, the pin d4 lying in the forward end of the slots d2, and that when the bolt is shot the pin d* will traverse in the vslots d2 in the forwardly-moving bolt-piece until the rearward end of the straight part of said slots is reached, when the further forward movement ot' the bolt-piece will cause the pin d4 to enter the inclined heel portionsdof the slots d2, and thus throw or protract the several sections of the bolt-piece n alternately opposite directions edgewise, and so that they project sidewise beyond the lines 0f the bolt-plate, as shown plainly in Fig. 2, and tl1at,rhe vpin d4 fitting snugly within the portion d3 of the slot, the strain npon the bolt-piece will be wholly or almostwholly borne hy said pin, and the pivot d will be relieved of all or nearly all strain.

The lock which I have shown and described is peculiari)1 adapted for use in securing the lids ol' boxes and in siinilar structures.

What I claim as my invention, and desire to secure h v Letters Patent, is"

In a lock, the combination, with the actuating mechanism, including a bolt-plate, B, of
