JOSEF THOMER AND FRANZ KOHAZY, OF KASCHAU, AUSTRIA.

SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 224,115, dated February 3, 18 80.

Application filed October 23, 1879. Patented in Germany, June 19, 1878, and in Austria, October 14, 1878.

To all whom it may concern Be it known that we, JosEE THOMEE, of the city of Kaschau, and FRANZ KoHAZY, also of Kaschau, in the Empire of Austria, have invented new and useful Improvements in Locks for Railway-Carriages, of which the following is a specification, and for which invention we have obtained Letters Patent in Austria under date of October 14,1878; in Germany under date of June 19,1878; and have filed applications for Letters Patent in England on July 23, 1879; France, July 25, 1879; Italy, July 27,1879; Belgium, September 17, 1879; and Russia, beptember 18, 1879.

The object of our invention is to replace the usual seal of such locks by a controlling check or slip, which shall show the place and date, or the place, date, and hour, where and when the lock has been closed or opened; and to that end it consists in a lock in which the locking-bolt is liberated by the depression of the tumbler, said lock having achamber adapted to contain and hold a check-slip, said chamber being provided with an opening for stamping or imprinting upon one part of said slip the information of the closure of the lock, and an opening for depressing the tumbler under another part of the said slip, and at the same time stamp or imprint thereon the information of the opening of the lock, in combination with a key adapted to perform these various func tions of stamping and opening the lock.

The invention further consists in certain details of construction, as hereinafter described, and as shown in the accompanying drawings, in which Figure 1 is a front elevation of our improved lock, showing the check-slip chamber open. Fig. 2 is a side elevation; Fig. 3, an interior view of the front section of the lock; Fig. 4, a front view of the rear section of the lock. Fig. 5 is a vertical transverse section taken on line as m of Fig. 1, showing the key in position for opening the lock. Fig. 6 is a like view taken on line 2 z of Fig. 2, the key being removed.

' Fig. 7 is a horizontal section taken on line yy of Fig. 1. Figs. 8 and 9 are an under-side plan view and a side elevation, respectively, of the key; and Fig. 10 is a plan view of the check-slip.

Similar letters of reference are employed to indicate like parts wherever such may occur in the above-described figures of drawings.

The lock is composed of two sections, the main casingA and the'back plate, 13, the former having in its interior suitable seats aa for said back plate, the seat a forming, also, hearings for the fastening-bolts O. The casing A is furtherprovided with a bearing, a, at its lower end for a third fastening-bolt, G. The face or front part of the casi n g is recessed, and in this recess A fits closely a lid, I), hinged at d to the lower end of the casing A. The inner face of the lid Dis recessed to receive the check-slip hereinafter described, and has two openings, D D, a catch-hook, d, and a hand-hold or knob, d.

The back plate, 13, is provided with two projecting ledges, b b", between which is held and slides the tumbler E, and a bearing orshouldcr, b, that fits upon the seat a of the casing A. The back plate, B, also carries the pivot-pin F for the bolt 01' latch L, a guide-pin, E, for the tumbler E, and four retaining guide-pins, e, for the four strong spiral springs E", which are seated in recesses b e formed,respectively, in the back plate and the tumbler, as shown in Figs. 5 and 6, the tendency of said springs being to force the tumbler outward or away from said back plate, B, except when forcibly pressed inward, as hereinafter described. Finally, the back plate, B, is provided with bolt-holes 11, corresponding in location with like holes in the casin g A, for the reception of the fastening-bolt O.

The tumbler E consists of a plate having its lower half of increased thickness, to form the shoulder 0 across its face, and a recess, 6, on one side, which latter, together with the shoulder 6, forms a rectangular bearing or seat, E, for the rectangular lower face, l L, of the locking bolt or latch L when the latter is locked by the tumbler, as shown in Figs. 3, 4, and 5. The tumbler E is further provided with a perforatedcylindrical boss or hub, E, projecting from the face of said tumbler into a corresponding opening, A, in the casing A, and through said boss passes the pointed guidepin E, the point of which projects slightly beyond the face of the boss, which latter, in its normal position, is flush with the recess A of the casing A, and forms a bearing for the key, by means of which the tumbler is depressed for unlocking the lock, as hereinafter described. Within the longitudinal center of the recess A of the casing is formed ai'ecess, a, gradually increasing in depth or sloping toward the opening A, in which it terminates, for a purpose hereinafter described. The tumbler E is further held in position and guided by a pin, G, fitting in a groove, g, formed in the lower enlarged edgeface of said tumbler, and said pin or guidescrew G is secured to the lower hearing or ledge, I), of the back plate, B, as shown by Fig. 6.

Upon the lower front face, adjacent to the projecting hub or bearing 13, is a semicircu-' la-r tapering groove, 9, having its front edge, g, slightly beveled for the reception of the bolt H, which passes through a bracket-bearing, h, on the side of the casing A. The outer end of the bolt has a square head, h, adapted to tit, when pushed inward, the rectangular face of the bracket, which thus forms a lock for said bolt to prevent its being rotated. The inner end. h, of said bolt is of increased diameter, forming a shoulder, which abuts against a like shoulder in the opening through which said bolt passes, to prevent its falling out or being withdrawn entirely, the extent of motion of said bolt outward being such that when fully drawn out the face of its inner end will be flush with the inner face of the casing A and out of the way of the tumbler E.

Upon the inner face of the casing A, near its upper end, upon its vertical center, is a sliding bolt, I, having at its lower end a projecting and slightly beveled shoulder or bearing, 2'. It is slotted to receive the catch (1, and is held down or depressed by a spring or springs, 1, except when pressed upward by the lockingbolt, as hereinafter described. The sliding bolt and spring are located within a suitable recess formed in said casing A, and held in proper position by a covering plate, i, as shown in Figs. 3 and 5.

"Upon opposite sides of the case A and flush with its front face are formed the lugs K K and K K, in proximity to the openings D D, said lugs forming bearings for the key when the slip or check is to be stamped after closing the lock, or when the key is applied to open the lock, as hereinafter described.

L is the locking-bolt, having the form, in side elevation. shown in Figs. 3 and 4 and in dotted lines, Fig. 6, and in front elevation partly in section, in Fig. 5, with the rectangular engaging-faces l and l, engaging with like bearingfaces 0 0 on the tumbler, the round head l engaging the shoulder on the sliding bolt I, the depression 1, and the nose 1. The bolt L is further provided with the engaging or looking spurs or arms L, adapted to engage a hook or like device on the cardoor framing or on the car-door, according to where the lock is bolted, as will be readily understood.

Referring to Figs. 5, 8, and 9, M represents the key, which consists of a flat rectangular bar, m, of metal, the part M, that is pivoted to the front end of said bar or handle m, and the follower N. The part M has a shank, m, the transverse arms m, and the arms m m The distance between the latter is such that the part M may he slipped OVBI the casing A and its arms m m brought into engagement with the rectangular lugs K K or K K.

The bar or handle on of the key, near its front end, has a depending ear or lug provided with a segmental slot, m, for the reception of a pivot-pin, upon which is mounted one end of the rectangular bars a, and between the front end of the latter is pivoted the shank of the follower or plunger N, having a hollow cylindrical head, a, the front face of which is provided with letters orn um bers, or both or any other desired cancelingordistinguishing mark to be imprinted upon the check-slip X when closing and opening the lock. The shank m of the part M of the key has a depending flat lug, which passes through the slot formed by the space between the bars a, said lug on being provided with a flat head, M, upon which said bars slide when the handle m is depressed or elevated to throw the follower or plunger N forward or back ward.

The operation of the lock is as follows: X is a check-slip, composed of two disks united together by a narrow strip, or, the whole stamped out of pasteboard, soft metal, or other suitable impressible and flexible material, the diameter of the disks being such that one of them will closely fit the recess d around the opening D, while the connectingarm 90 of the disks will fit closely the recess d on opposite sides of the slit or opening D, which unites the openings D D in the lid D, and the latter, fitting snugly in its recess in the casing A, will hold the slip X firmly in position except that portion of said slip which is depressed, as hereinafter described.

This check-slip being placed in position and the lid D closed, the bolt L is swung down to engage its arms L, or one of them, with a suitable latch or fastening device, the bolt or pin H being drawn out, as shown in Fig.1. The diflerent parts of the lock will then be in the position shown in Figs. 2, 3, at, and 5. The key M is nowplaced over the face of the look, so that its recessed arms m will be hooked over the lugs K K and the follower over the opening D of the lid D, when the arm on is depressed, and the follower forced forward to pass through said opening D and imprint upon the check-slip X the day, (late, and place when and where the lock has been closed, or such other mark as may be agreed upon for that purpose.

If it is desired to open the look when the car has reached its destination, or at an intermediate point, each station being provided with like keys, said key is now applied to the face of the look, so that its recessed arms will be hooked over the lugs K K and the follower N over the openings D of the lid 1). If said follower is now forced forward onto the lower disk of the check-slip X, which lies upon the cylindrical boss E and the pointed guidepin E, the said boss will be depressed, and when its bearing E, formed by the shoulders e and 0, has cleared the rectangular looking-faces l I, said bolt may be swung around on its pivot-pin F upward, and thismoveinent causes its rounded head I. to come in contact with the shoulderi of the slot-ted bolt I, press ing the latter upward to release the catchhook d. on the inner face of the lid D, so that the unlocking of the bolt or the disengaging of said bolt from its retaining devices by the depression of the tumbler and the upward movement of the said bolt simultaneously unlocks the check-slip chamber.

The opening of the lock by the depression of the tumbler performs still another function besides the unlocking of the check-slip chamber and the stamping of the lower disk of the check-slip Xnamely, the said checkslip is canceled by the act of depressing the tumbler, during which rearward motion of the tumbler the pointed guide-pin E is forced through the check-slip and passes into the follower N, and for this reason I provide a hollow cylindrical follower .or stamp, N, and a recess of graduallyincreasing depth, a, within which the uniting-strip a: of the disks of the check-slip X will lie when the tumbler is depressed. The depth of the recess a at the point where it terminates in the cylindrical opening of the casing is equal to the distance the tumbler is moved inward or backward.

It will be observed that this provision is an important one, as without it the lower disk of the check-slip X would invariably be severed from the shank a; when the follower N is forced inward or forward to depress the tumbler, which is not desirable, as this would destroy the record, and would prevent the use of the other faces of the disk when the lock is opened prior to the arrival of the car at destination, which is often desi able.

If it is desired to use the lock simply as a fastening device, to be opened and closed at will without having recourse to the key, the tumbler is first depressed, and then the pin G is placed in position relatively to the bracket to permit of its being slipped inward into the semicircular groove g in the front face of said tumbler, and the latter is then released, the pin holding it back out of engagement with the bolt L, which is then free to swing upon its pivot F, and when turned down in a horizontal position the shoulder t on the bolt 1 will lie near the depression 1, at the lowest forward point of the rounded portion 1 to permit the bolt Ito engage the catch (1 of the lid D; but when said bolt is swung upward the rotation upon its pivot F will bring the higher portion of the head in contact with said shoulder i and push the bolt I upward to release the catch, as already described.

To prevent the bolt L from moving inward with the tumbler, that part of the pivot-pin F upon which said tumbler slides is made of increased diameter to form the shoulder j, which forms a seat for said bolt and serves to hold it always in proper position, as will be readily understood, and as plainly shown in Figs. 3, 4,

5, and 6.

It. will also be observed that the spiral or actuating springs E are arranged around and equidistant from the cylindrical boss E, whereby the pressure or power of said springs is applied uniformly.

We have described a tumbler having a cylindrical boss or hub, E, passing into a corresponding opening formed in the casing, and a key having a cylindrical head provided with alike axial opening. It is evident, however, that this precise form is notindispensable, nor is it necessary that the openings 1) l) in the lid should be cylindrical, as any other desired form may be given to these partsin crosssection, the check-slip being correspondingly shaped.

Having now described our invention, what we claim, and desire to secure by Letters Pat.- ent, is
