LOCK.

SPECIFICATION forming part of Letters Patent No. 499,505, dated J' une 13, 1893.

Application filed March 31, 1893. Serial No. 4678.519. (No model.) I

To all whom, it may concern."

Be it known that I, WILLIAM F. BEASLEY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in a Combined Indicating and Seal Lock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a lock in which a rotating` barrel having a cross head thereon and journaled on anysuitable part, is adapted to be inserted through a slot in the opposite part (which if desired may be a hasp) and by being rotated, prevent the withdrawal of the 'said opposite parts until the cross head is again in the position to pass through the slot therein. A locking mechanism may be provided to prevent the unauthorized rotation of the barrel carrying the cross head, or an indicating mechanism may be used `to record or indicate the rotations of the said barrel, which in such a case is' provided with means to prevent its backward rotation; or a suitable seal may be applied in such a manner as to prevent the forward rotation of the cross head from its locked position Without destroying the seal, the rearward rotation thereof being prevented by the mechanism applied to the barrel for that purpose; or any or all of the said locking, indicating or sealing mechanism may bek used together and in combination. In case the indicating mechanism is used, I by preference, cause the numerals upon the indicating disks thereof to be seen through the slot through which the cross head is inserted, so that it will be hidden by the said cross head, when the latter is in a position to permit its insertion through or removal from the said slot (this being its unlocking position) preventing the inadvertent leaving of the cross head in such a position, as it must be moved in order to read the register.

My invention,moreover, consists in the construction, arrangement and combination of the several parts of which it is composed, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which represent a lock especially adapted for use as a car door lock, and in which drawings corresponding parts are designated by similar marks of reference, Figure 1 is a side elevation of a lock constructed in accordance with my invention and applied to a freight car. Fig. 2 is a horizontal section on lines X X thereof, and of Fig. 4. Fig. 3 is a vertical, transverse section on linesY Yof Figs. 1 and 4. Fig. 4 is a vertical longitudinal section on lines Z Z of Fig. 3. Fig. 5 is a horizontal longitudinal section through the seal lock on lines Z Z', Fig. 1. Fig. 6 is a detail view of a form of key.

A suitable aperture is bored in the side (A) of the car adjacent to the dooropening therein, and in this aperture the barrel 1 is mounted, in the front and rear plates 2 and 3, respectively, which are circular and have their edges united by the cylinder casing 3a, the plates having ears 4 projecting from the periphery thereof, through which ears and through the side of the car bolts 5 are inserted, the bolts being fastened from the inside of the car. Flanges 6 are formed around the periphery of the plates 2 and 3, the said anges as well as the ears 4 being sunk in the sides of the car,.and being flushed With the surfaces thereof. The rear plate 3 is made of considerable thickness, and has the central bore 7 formed therein, the forward end of the bore being reduced in size. The barrel l has an enlargement 8 formed on its rear end and contained in the enlarged portion of the said bore, while the forward portion of the barrel passes through central bore 9 in the face plate 2, and has its projecting forward end squared, to receive the elongated cross head 11, the end of the barrel being upset to hold the latter in place. The cross head revolves above a boss 12 formed on the face plate, the said boss, being substantially the same shape as the cross head, but being by preference slightly larger.

When it is desired to -use an indicating mechanism to record the rotations of the barrel, an aperture 13 is formed in the boss 12 and the face plate on which it is formed, the said aperture being on one side of the bore 9 through which the barrel l passes, and an indicating mechanism, such as that described in another application filed by me in the United States Patent Office on the 13th day of February, 1893, and serially numbered IOO 462,112, is placed within the compartment formed by the cylindrical casing 3"L between the rear and face plates 3 and 2, respectively. The essential feature of such an indicating mechanism as shown in the drawings, consists of indicating disks 14 which are seen through the apertures 13, they being journaled on the barrel 1, and connected by concentric sleeves 15, with notched floating disks 16, which are engaged by pins 16a upon floating wheels 17, which are journaled on a stud 18 projecting from the rear plate 3, the said notched disks 16 being thrown thereby, while each of the floating wheels is thrown by the shoulders 19 thereon, engaging projections 2O on the iioating disk immediately adjacent thereto. The first floating wheel is thrown by a projection 21 contained in a groove 22 in a collar 23 keyed on the said barrel 1, the said projection 21 being placed at such a pointin the groove as to throw the Iirst floating wheel, and thus the indicating disks (which have a series of marks on their faces) upon the initial movement of the said barrel from the position in which the cross head 11 thereon lies at right angles to the boss 12 on the face plate, (the position shown in the drawings.)

As will be noticed, the cross head will, in its rotation with the barrel l, lie above and be symmetrical with the boss 12, twice in each revolution thereon, thus covering the aperture 13, and the indicating disks, and will also lie at right angles to the boss 12 twice in each revolution of the barrel, and to provide means for recording the rotation of the barrel from the latter of these positions, two projections 21 are placed in the collar 23,at diametrically opposite sides thereof, so that one of the said projections will throw the first fioating wheel and thus the indicating disks upon the rotation of the cross head from either of the said last named positions. In order to provide means for locking such a cross head, when in a position at rightangles to theboss, two series of apertures 25 are formed in the rear plate 3 at diametriclaly opposite sides thereof, the said apertures being radial in respect to the bore 7 therein, while a single similar series of holes 26 is formed in the enlarged rear end of the barrel 1 vin such a position that they will register with one of the series of apertures 25 in the plate when the barrel is in such a position as to cause the cross head thereon to be at right angles with they boss 12, theinner ends of the holes 26 communicating with one side of a longitudinal slot 27 formed in the barrel, and extending, if necessary, through the cross head, into which slot a suitable key may be inserted, to move thev pins 27 contained in the said holes 26 a sufficient distance outwardly to cause the inner ends of pins 29 contained in the said aperture 25 to be Hush with the periphery of the. enlargement S on thebarrel, thus unlocking it for rotation, the pins 29 being shoved outwardly by springs 30 contained in the outer ends of the apertures 25. It will thus be noticed that the barrel l is adapted to be locked twice in each revolution and at diametrically opposite points by the pins 29 contained in one of the sets of apertures 25, and at such positions as to canse the cross head 11 to be at right angles to the boss 12, which as before stated is the position upon the rotation of the barrel from which the indicating mechanism will be thrown. In order to prevent a backward rotation of the barrel from such a position, or from a position -in which the cross head lies above and symmetrically to the boss 12, a series of rearwardly facing shoulders 30'v1 is formed on the enlargement 8 of the barrel at ninety degrees apart, the said shoulders lying in the same plane as one of the holes 26 in the barrel, so that they will be engagedby the pin 29 in one of the apertures 25 and by the pin in the corresponding aperture of the opposite set thereof. The backward rotation, which is thus prevented,is objectionable, inasmuch as it would tend to destroy the accuracy of the indicating mechanism. The part which I have shown as adapted to be locked by such a cross head consists of a hinged hasp 31, secured to the car door (B), the said hasp having a slot 32 therein corresponding to the boss 12, which it is adapted to receive, and over which it may be placed, when the cross head 11 lies above and symmetrically to the said boss. It will be obvious thatif after placing the hasp upon the boss, the cross be turned through an arc of ninety degrees causing it to assume a position at right angles in respect to the boss and to the slot 32 in which the latter is contained (the position shown in Fig. 1) that itwill beimpossible to remove thehasp until the cross head has been again rotated in a forward direction through an arc of ninety degrees, causing it to again lie above and be symmetricalwith the boss, the backward rotation of the cross head being prevented by the shoulders 30a on the enlargement 8. Such a forward movement of the cross head cannot be made, however, without throwing the registering mechanism as before described, and without using a key to unlock the locking mechanism, if such latter mechanism be provided. It will be noticed also that vthe indicating mechanism, which should, be read upon each locking of the car, and each unlocking thereof, (which two successive readings should correspond) aifords a means of detecting an intervening unlocking, while, as the registering mechanism cannot be read, while the cross head covering the indicating mechanism whenv in its unlocking position, will prevent the inadvertent omission to turn the former to its locking position, as the indicating mechanism cannot be read until this is done. It will be evident however that the boss may be formed solid and the slot formed in any other portion of the face plate, whereby the indicating disks will be covered by the cross head, when the latter is in a locking position, if desired. It will also be noticed that the boss 12 occuilo `the car and to enter a recess 33 in the hasp,

when the latter is in a position to be locked by the cross head.

When it is desired to use a seal, I provide a block 40 which is adapted to be secured in place by one of the bolts 5 and by a nipple or lug 41 projecting from the face plate 2 and takingdnto an aperture 42 in the block, the

upper end of which block is adjacent to the hasp 31 when the latter is closed, and has a groove 43 in its upper end, While abifurcated horn 44 projects from the grooved portion of lthe block and between the parts of this horn and through the groove in the block the ends of the cross head 11 are adapted to pass upon the rotation thereof. Shoulders 45 are formed at the junction of the horns with the block on the upper and lower sides thereof, while other shoulders 46 are formed upon the upper and lower surfaces of the block at its junction with the horns. Over the horns a sheet metal seal, having a slot 4S in one end thereof is adapted to be placed, while the cross head is in an unlocking position, the

horns passing through the slot in the seal. If this be done it will beY obvious that when the cross head is rotated to its locking position, the seal will prevent the forward rotation thereof to unlock the hasp, the rearward rotation of the cross head being prevented by the shoulders 30a, and it will be also seen that to rotate the barrel forward it will be first necessary to destroy the seal. When such a seal is provided, I may if I desire, dispense with both the registering mechanism and a part of the locking mechanism (that is to say, the pins 27, and the slot 27a in the barrel, leaving the spring pressed pins 29 and the shoulders 30a onY the barrel in order to prevent the backward rotation thereof,) or I may dispense with either the indication or the said portion of the locking mechanism. In case, however, I desire to use the indicating mechanism with the sealing mechanism described, I may if I desire cause the state of the register to be suitably marked on the seal, thereby affording a convenient reference for comparing the reading of the indicating mechanism when the car door is opened. It will also be noticed that from the method in which the block 40 is secured it can be readily removed or replaced, as it is desired to remove or use the sealing mechanism, it only being necessary to remove a single bolt 5.

I may if I so desire, instead of forming the slot 27 a in the barrel 1, in the form shown in Figs. 1, 3 and 4, make it circular in cross section, as shown in dotted lines in Fig. 4, such a hole being bored in the front end of the barrel and being adapted to receive a key (such as shown in Fig. 6), which is also circular in cross section and provided with annular grooves 50 in its rear end, the said grooves being adapted to move the pins 27, and to hold them in the proper position for unlocking the barrel. It is obvious that such a key when inserted in the hole 27 will release the locking mechanism, and that it will be capable of being turned in the said hole without turning the barrel, and without affecting its result upon the locking mechanism, thereby rendering it necessary to turn the barrel by means of the cross head thereon, and preventing it from being turned by the key, thus removing the strain from the latter, which would tend to break it. I may also, if I so desire, place on the forward end of the barrel a block of soft rubber, such as 5l, the block covering the forward end of the slot of hole 27, and having a slit such as 52 cut in it, over the said slot or hole, through which the key may he pushed, while upon withdrawing the key, the rubber will expand and again entirely close the forward end of the slot or hole, preventing the entrance of moisture or dirt.

In another application tiled by me on March 17, 1893, Serial No. 466,448, I have described and claimed a construction in which a barrel, having a cross head thereon, and provided with mechanism whereby it may be locked at -opposite point-s, is used in combination with an indicating mechanism consisting of a series of disks thrown by a rotation of the barrel, and I do not therefore desire to claim such a combination herein broadly, but
