SPECIFICATIEON forming part of Letters Patent N 0. 599,956, dated March 1, 1898.

Application filed. April 21, 1897- To aZZ whom it may concern.-

Be it known that I, HIRAM B. BROWER, a citizen of the United States, and a resident of Oxford, in the countyof New Haven and State of Connecticut, have invented certain new and useful Improvements in Oar-Door Fasteners, of which the following is a specification.

My invention relates to fasteners for cardoors and the like, in which a frangible plate or disk seal is used in a way whereby the fastener cannot be opened without destroying the seal as a means of detecting fraudulent opening; and it consists of improvements in the construction of the apparatus of the fastener for greater simplicity, cheapness, and durability, as hereinafter described, reference being made to theaccompanying drawings, in Which- Figure 1 is a front elevation of my improved car-door fastener closed and sealed. Fig. 2 is a top view of the fastener with the shell of the sealing apparatus sectioned on line 2 2, Fig. 1. Fig. 3 is a front elevation of the shell of the sealing apparatus, the rest of said apparatus being removed to show the bottom of the shell. Fig. 4is asection of the bottom of the shell on line 3 3, Fig. 3. Fig. 5 is a section of the bottom of the shell on line 3 3, Fig. 3, also of the cam-ring for actuating the seal-breaker, and also a plan view of part of the under side of the said shell. Fig. 6 is a sectional elevation of the pivot-stud for the hook and holder for the seal and aside view of the seal-breaker. Fig. 7 is'a side view of said stud and holder. Fig. Sis a front elevation of the stud and holder. Fig. 9 is a side view of the cam-ring for actuating the sealbreaker. cam-ringfor actuating the seal-breaker. Fig. 11 is a plan of the other side of said cam-ring. Fig. 12 is a front elevation of the improved cardoor fastener adapted for holding the door closed,as usual, or partly open for ventilation. Fig. 13 is a front elevation of the improved car-door fastener adapted for holding the door closed, as usual, or partly open for'ventilation, and also adapted for use either right or lefthanded. Fig. 14 is a front elevation of the improved car-door fastener in a modified form of construction for holding the door Fig. 10 is a plan of one side of the Serial No. 633,107. (No model.)

closed or partly open and also adapted for use either right or left handed.

A represents an ordinary hasp of any approved form and construction adapted to be hung on the door-frame or door by a staple a or other approved means and having the usualslot-eye b for lodging on the staple c on the other part relatively to the part on which staple a is secured. 1

01 represents the hook or hooks pivoted on the hasp and having the usual prong e for engaging the staple c to secure the hasp thereon. The pivot-studffor the hook is riveted or otherwise securely fastened in the hasp, as at g. It is bored centrally and longitudinally for reception therein of a sliding seal-breaking plunger h. The pivot-stud has in its part projecting from the face of the hasp, first, the section '5 larger than the stem riveted in the hasp and on which the pivot-eyej of the hook fits; second, the larger and longer section 7.0, on which the cam-ring Z works, and, third, the head m, in the face of which is the groove 0?. for reception of the seals 0 to be broken.

' The hook d has in its pivotal hub the hollow cylindrical shell 19, coincident with the pivot-eye j, for inclosing the projecting portion of the pivot-stud and the cam-ring and for retaining the seal 0 in the groove of the head of the pivot-stud, the depth of said shell being equal to the'extent of the projection of 'the head of the stud from the face of the hasp, and on the surface of the bottom of the shell is a series of ratchet-teeth q, surrounding the eye j, and in the outer end and at one side of the shell is a notch s; which when the hook is turned upright coincides with the groove n in the head of the pivot-stud and permits the seals to be inserted through the notch into the groove, Where they are retained by the unnotched part of the shell when the hook is engaged with the staple for securing the hasp, the sides of the groove being suitably undercut for overlapping the edges of the seal.

Over the ratchet-teeth q in the bottom of the shell the cam-ring Z is placed, said ring being bored to fit and turn on the part is of the pivot-stud and having other ratchet-teeth 'u on its side bearing against teeth q of the shell, these two sets of teeth being so formed that when the hook is raised to release the prong e from staple 0 its teeth q will engage the teeth a of the cam-ring and turn said ring; but when the hook swings down its teeth q will not take effect on the cam-ring, which will remain at rest. The other side of the cam-ring Z has cams '2), on two of which stud-pins w of the seal-breaker rest, said studs projecting through slots at in the part k of the pivot-stud, so that when the camring is turned by lifting the hook the sealbreaker will be thrust forward against the seal and will break it before the prongerises out of the staple c, and thus will always show when the door has been unfastened, there being no means of removing the seal without breaking it after the hook has been engaged with the staple.

Cams o are provided in ring Z at such distance apart that studs 10 will escape from those effecting the break onto the next ones before the upward movement of the hook ceases, to allow the plunger to recede to permit the next seal to be inserted,and a coiled spring y between the head on of the pivot-stud and the flange t of the cam-ring keeps the ratchetteeth of the cam-ring in engagement with the ratchet-teeth of the bottom of the shell, the plunger being free to be pressed back read ily by the finger when a new seal is to be inserted.

It will be seen that the seal-breaking devices are so effectually inclosed that they are in no way accessible for evading the safeguard. The seal can be of any suitable size for being conspicuously visible, and there is no possibility of fraudulently securing the hook at a height that will leave the hasp free to be released with a seal unbroken.

The line .2, Fig. 1, indicates the joint between the olosed door and the door-frame, the fastener being adapted for fastening the door shut; but it is sometimes desirable to fasten the door partly open to leave a space for ventilating, as indicated by lines 2 and z, for which the hasp and the hook may be extended, as in Fig. 12, and provided with an additional eye I) and prong e, respectively.

In Fig. 13 I represent a contrivance of hasp and hooks for fastening the door partly open or entirely shut, which is also reversible for application alike to right or left handed doors. In this case the hasp A has the pivot-stud located between the staple-eyes b and there are two hooks d,proj ectin g in opposite directions, respectively, from the pivot-stud and each having a prong e said hooks being in the reverse arrangement, whereby they both act alike with reference to the eyes of the hasp when either one is shifted, so that either eye being lodged on a staple said staple will be engaged by a hook. The two hooks balance each other on the pivot, and the resistance of the seal-breaking devices, occasioned by a seal in place, prevent them from jarring open.

One of the hooks may be chained or otherwise fastened against such action, if desired. It

is obvious that this form of fastener is alike applicable for right or left hand doors, and in Fig. 14 I represent another modification of double and reversible hasp and hooks, which differs only from the arrangement of Fig. 13 in that the two hooks d are connected to the shell of the seal-holder both at one side of the plane of the axis of the shell instead of on opposite sides of said plane and in such way that both hooks range across said plane in the same direction and engage the staple c by swinging from above downward. When the hasp A is reversed for application to a reverselyopening door, the hooks are turned half-way around and set to the upper side, same as before, and will act alike, as in the other ad 3' ustment.

It will be seen that besides the several advantages apparent in the foregoing description the improved seal-breaker avoids one operation of other seal-fastenersthat is,breakin g the seal before openingand it avoids the necessity of carrying a hammer, and it also avoids damage to the fastener, which often occurs by the use of stones for a substitute when the hammer is forgotten, which, not being of proper shape, often damage the sealholding parts.
