LOCK.

SPECIFICATION forming part of Letters Patent No. 272,796, dated February 20, 1883.

Application filed February 24, 1882.

To all whom it may concern Be it `known that I, ELIsHA P. TEETERS, of Alliance, in the county of Stark aiid State of Ohio, have invented certain new and useful Improvements in Locks; and I do hereby declare the following tobe a full, clear, and eX- vact description of the invention, such as will locked, and which shall combine simplicity of construction and ease of operation with durability and efficiency in use.

With these objects in view my invention consists in certain details of construction and combinations of parts, as will be hereinatter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of a lock constructed in accordance with my invention. Fig. 2 is a rear view thereof. Fig. 3 is a view of the interior of the lock-casing. Fig. 4 is a view of the lock in vertical longitudinal section, showing the parts of the lock in the adjustment due to them when it is locked, the lock-bolts being engaged with suitable staples. Fig. 5 is a plan view ot the lock-bolts andthe various devices with which they` are associated, the shield ofthe case in which the said bolts and devices are iiiclosed being removed. Fig. 6 is a similar view, showing the lock-bolts alone. Fig. 7 is a detail view ot' one of the loclobolts. Fig. 8 is a View of one of the slides. Fig. 9 is a view of one of the spring-pressed lock-tumblers. Fig. 10 is a view of the ejecting-spring. Fig. 11 is a view of the shield ofthe case. l2 is a view in side elevation of a key adapted to fit the lock, and Fig. 13 is a view of a suitable staple to be engaged by the lock-bolts.

A is the lock-casing, constructed in any desired manner, but preferably foi-ined cfa single piece of metal. It is provided with perforated Ilanges B to adapt it to be secured to the article with which it is used. rl`he outer face, C, of the said lock-casing is provided with an elongated slot, D, which is closed by a suitable plate, F, located within the casing, and provided with a boss, Gr, conforming in shape Fig..

to the said slot, and provided with a key-hole, H. Suflcient space is left between tliefaceO ofthe casing and the bossed plate F to permit a label, I, to be interposed between them through the slot E, the said label being securely held in position by the friction derived from its detlection by the boss Gr. 1t is designed to indicate upon this label any descriptive matter, and when the locks are used upon mailbags a label indicati-ng the destination thereof will be employed. When in position in the casing the label covers the keyhole and eX- cludes dirt from the lock.

Lugs J, attached to the inner face and midway ofthe length of the plate F, are designed to support the ejecting-spring K, while similar lugs, L, located respectively on opposite sides of the lugs J, are intended to oder bearing for the shield M ofthe case N, which contains the lock-bolts O and the devices associated with them. The outer face of the said case N isA provided with two elongated slots, l), which receive the staples, and with a perforation, Q, to receive the screw by which the said case is attached to the casing A. Inclined bearings R, located in the four corners of the case N, are designed to supportthe bearing-faces a, formed on the opposite edges of the grooved plates T, which connect the ejccting-springs K. An upright stud, U, located in the center of the case, is adapted to receive the key W, while the studs X fulfill a fourfold function in detning. the reflex movement ofthe lock-bolts O in guiding the slides Y, in constituting fulcrums for the lock-tumblers Z, and in maintaining the shield M in proper adjustment. The said case N is perforated atA' to receive a stud, B, projecting from one of the end walls of the casing A, said stud and slot constituting a lock for one end of the case N, the other end thereof being held in place by a screw, O', inserted in the perforation Q, and extending into a registering-pertoration, D', formed in the outer face ofthe casing A.

Lugs E', projecting from the side walls of the case A, are designed to support the shield VM, which is provided with perforations F to receive the studs X of the case, and with a key-hole, G', the ends of the shield being cut away, as at H', t0 give increased play to the grooved plates T.

The lock-bolts O are provided with upright IOO bearing-plates I' at their rear ends, with two notches Y2.

rearwardly-extending arms, J and K', the longer arms, J', being provided with extensions furnished with bearing-plates L', located directly in the rear of the bearing-plates I', and with pins L2. The rear ends of the arms J' and K' of both of the said lock-bolts() impingeagainstthestudsX, and are limited in rctiex movement thereby, the forward motion of the bolts being defined by the engagement of the outer ends ofthe said arms J' and K' with the bearings R, before alluded to. Recesses M', formedin the said arms J', are designed to receive the lugs D2 of the key W, the thin walls b of the said recesses being received in slots U2, formed in the key itself'. When the said bolts are placed in their appropriate positions in the case N, their longer arms, J', will pass each other and respectively extend beyond the central stud, U, the bearing-plates L' of one bolt being in this manner arranged to constitute the bearing for the rear end ofthe spring N' of the other bolt, and vice versa, the outer ends of the said springs being arranged to impinge against the bearing-plates l'. Each spring will thus be adapted to tulill a twofold function in exerting a constant force to throw both bolts outward, and therefore should one spring break or become inoperative the efficiency of the lock will not'bc impaired.

The slides Y are provided cach with two lugs, O', which impinge respectively against the bearing-faces L' of the arms J' ofthe bolts O. They are also provided with wards P', located in the center of the concave recesses Q', formed between the lugs 0', and with elongated slots R' and S, respectively adapted to receive the studs X and the pins L2, and with pins T',which engage with appropriate recesses in the lock-tumblers Z, as will be hereinafter explained. The said lock-tumblers are provided with pert'orations U', adapting them to be pivotally secured to the studs X, and with springs V', which impinge against the side walls ot' the casing N, and exert a constant tendency to engage theinner faces of the tum-V blers with the pins L2 and T'. Theinner faces ot' the said tumblers are provided with shoulders WV', which engage with the pins L2 ci' the lock--bolts when the saine are in locked adjustment, preventing them from being pushed back, with recesses X', which receive the pins L2 when the bolts are retracted, with notches Y', adapted to engage with the pins T' when the lock is in its locked adjustment, with notches Y2, located on each side of the notches Y', and designed to receive the pins T' when the lock is unlocked, and with ledgesYi, with which the lugs A2 of the key engage. When the key is inserted into and turned within the lock for the purpose of unlocking it. its lugs A2 will engage with the said ledges Y3 of the tumblers, and by forcing the same outward break the engagements which exist between them and the pins L2 and T'. It will also .move the slides in opposite directions, and the It is necessary to turn the key back a short distance for the purpose of removing it from the lock, and when this is done the slides Y will be reversed sufficiently to engage the pins T', attached to them, with the notches Y2, the said pins being engaged with those of the said notches, which they pass when the slides are being actuated, as described.

It may be here observed that, by virtue of the construction and arraugementot' the lockbolts and the devices associated with them, in unlocking the lock the key may be turned in either direction, imparting precisely opposite movements to the slides when turned in one way from what it does when turned in the other direction. The object of engaging the pins T' with the notches Y2 is to .prevent the slides to which the said pins are secured from moving and assuming positions interfering with the introduction ot' the key. It', however, the lock should receive a sufficiently violent shock to throw the pins out ot' the notches Y2, they will fall into the deep notches Y'.

The key Wis provided with two sets of lugs to actuate the double system ot' levers and tumblcrs, the upper lugs, A2, being designed to operate the lock-tumblers Z,while the lugs B2 are arranged to engage with the wards P' ot' the slides Y. Slots C2 receive the thin walls b, covering the recesses M', formed in the longer arms J' ofthe bolts N, the lugs D2 of the key being adapted to enter said recesses.

Having described my improvement in detail, I will now describe the mode of its operation.

Let it be supposed thatthe lock is in its locked adjustment, that its bolts are engaged with staples, as shown in Fig. 4 of the draw ings, and that it is desired to unlock the lock and release the said staples. The label I is first withdrawn or slipped aside to permit the introduction of the key into the lock. As the key is turned therein the lugs A2 thereot' will engage with the ledges Y? ot' the tumblers Z, and by forcing the same outward release the pins L2, secured to the arms Jot' the lock-bolts, and the pins T', secured to the slides Y, from engagement with the shoulders YV' and the notches Y2, respectively, while the lugs B2 of the keys will engage with the wards P ofthe slides Y and force the same in opposite directions, causing them toretractthe bolts O by virtue ofthe engagement ofthe lugs O' with the bearing-plates L'of the arms J'ot'the said bolts O. The slots C2ot`the key receive the thin walls b of the recesses M',formed in the arms J', and adapted to receive the lugs D2 of the key. As soon as the bolts are withdrawn the grooved plates T, engaged with the staples,will, through the force ot' the springs K, eject the staples from the lock,the inner faces of the said plates being at the same time engaged with the outer ends ot' the lock-bolts, holding them against the force of the springs N' from resuming the positions due them when the lock isin its locked adjustment.- The lock-bolts being engaged, as described, the key is reversed for the purpose IOO IOS

IIO

of withdrawing it from the lock, and as it is turned the lugs B2 will engage with the walls of the concave recesses Q.' ofthe slides Y and move the same, causing the pins T, attachedto them, to engage with the appropriate notches Y2. supposing now the lock to be in its unlocked adjustment, if the staples are pressed against the plates T, they will recede and permit the said staples to enter the lock. As the plates T are forced inward the lockboltsN will be released and thrown forward to engage with the staples, retaining them until the lock-bolts are again withdrawn by the action of the key. V

From the foregoing description it will be apparent that the lock not only automatically engages with the staples, but also forcibly ejects them.

In conforming my lock to the different uses to which it may be applied, some changes may be necessary. I would therefore have it understood that I do not limit myself to the exact construction shown and described, but that I leave myself at liberty to make such slight changes and alterations as fairly fall wit-hin the spirit and scope of my invention.

WhatIclaim as new,and desire to secure by Letters Patent, is-

l. The combination, with a lock-casing the outer. face ot' which is provided with an elongated slot, of a plate located withiirthe casing and provided with a boss conforming in shapito the slot, said boss having a key-hole formed in it, and a label interposed between the outer face of the lock casing and the bossed plate to cover the key-hole in the latter and exclude dirt from the lock.
