L CK-HIN GE.
Application filed February 6, 1915.
To all whom it may concern:
Be it known that we, TAYLoR E. SLEDD and Josnrn T. DIXON, citizens of the United S ates, residing at East Radford, in the county of Montgomery and State of Virginia, have invented certain new and useful improvements in Lock-Hinges, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to an improved lock hinge and has for its primary object to provid simple and effective means for positively looking a hinge pintle against turning moi ement to retain the memloer to which the pintle is secured, in an adjusted position.
it is another and more particular object of the invention to provide a lock hinge and an operati key therefor adapted for engagement with the hinge pintles to turn the smile, the hinge knuckle in w iich the piutle is mounted being provided with means cooperating with means on the shank of the key to prevent the withdrawal of the key leiore the turning movement of the pintle rom one position to anot ier has been com- -t is an additional object of our invention to provide a lock hinge which is simple in its construction, may be employed for a variety of purposes and can be manufactured at comparatively small. cost.
With the above and other objects in View, our invention consists in the novel features of construction, combination. and arrange ment of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,
Figure l is a side elevation of a portion of a railroad car, showin an indicating device applied thereto which is pr vided with our improved lock hinge; Fig. 2 is a similar view, partly in section, showing the sign plate in its open or exposed position; Fig. 3 is an enlarged fragmentary vertical section showing the key inserted and the locking dog in released position; Fig. a is a section taken on the line -ll of Fig. 8; and Fig. 5 is a detail perspective view of the. key.
Referring in detail to the drawing, designates the bracket plate or holder, upon op posite ends of which ears 6 are formed, said ears being provided with openings for the reception of suitable fastening screws inclicated at 7. Upon one end of this bracket Specification of Letters Patent.

plate, upwardly and downwardly projecting extensions 8 are integrally formed, such eX- tensions being also provided with ears 9 at their extremities to receive additional fastening screws. Upon the extensions 8 of the bracket plate and above and below the body of the plate, the outwardly projecting knuckles 10 and 11, respectively, are formed.
It will be understood that the accompanying drawing is illustrative of only one oi themany uses to which our im roved lock hinge may be applied, and it is to be under stood that the invention is not limited to such use but may be advantageously employed in all other instances where a locking device for the hinge pivot or pintle or" a movable element, is necessary or desirable.
The sign plate, shown at 12, is formed from a metal sheet of requisite dimensions, and upon one side of this sign plate, the raised letters 13, forming the word shop are molded.
l-i designates a pintle to which the plate is rigidly secured by means of suitable rivets 15. The upper knuckle 10 is formed with a socket 17 opening upon the bottom face of said lug. This socket is designed to receive the upper end of the pintle 14. The lower knuckle 11 is provided with a longitudinal opening 18 extending entirely therethrough, and said opening receives the lower end of the pintle. Upon the pintle, the flange or collar i9 is fixed to rest upon the upper surface of the knuckle 11 and prevent downward movement of the pintle therethrough. This collar is preferably provided with a knurled outer edge and provides convenient means for turning the pintle in the knuckle.
The lower end of the pintle 1%, below the collar 19, is provided with a slot 20 which, at its inner end, extends entirely through the pintle. At the outer end of the slot 20, obliquely inclined walls 21 converge inwardly and meet at the longitudinal center of the pintle. This slotted end portion of the pintle is oi rectangular form in cross-section, as clearly shown in Fig. i, and a locking dog 2 is pivotallymounted at one of its ends, as shown at 23, in a recess 24- formed in the wall of the knuckle 11 and communicating with the opening 18 thereof. A leaf spring is fixed at one end to said knuckle, and bears against the base wall of said recess to normally force the dog outwardly and into the slot 20 in the pintle, said dog resting against one of the inclined end walls 21 of said slot.
26 designates the key which is provided with a cylindrical shank having longitudinally extending grooves 27 therein, on diametrically opposite sides. their inner ends, communicate with an an nular groove 28. The shank of the key is further provided with a longitudinally extending rectangular bore 29. At the lower end of the opening 18 in the knuckle 11, an inwardly projecting stud 30 is formed upon the wall of said knuckle, and is adapted to be received in either of the slots 27 in the key shank when the key is inserted or withdrawn from the knuckle, as hereinafter more fully set forth. Each of the knuckles 10 and 11 is provided with a duct 31, leading to the socket or bore thereof whereby a suitable lubricant may be conveniently supplied to the ends of the pintle.
In the operation of our improved lock hinge, the key shank is forced upwardly into the knuckle 11, the square end of the pintle being received in the bore of the key shank and the stud 30 on the knuckle engaging in one of the grooves 27. As the shank of the key is forced upwardly, it exerts a pressure against the edge of the locking dog 23 and forces said dog into the recess 2% against the action of the spring 25. The pintle may now be turned or rotated, the lug 30 being accommodated in the annular groove 28 in the key shank. Then the pintle is turned, the plate 12 is swung from one position to another, and it will be seen that the pintle and the member to which it is attached, must be moved through an arc of 180 before the key can be withdrawn, in order that the lug 30 will be in line with the other of the longitudinal grooves 27 in the key shank. W hen so disposed, the key can, of course, be readily withdrawn from the hinge knuckle.
V lVhile we have shown and described the preferred construction and arrangement of the several elements employed, it is to be understood that the invention is susceptible of considerable modification therein and we, therefore, reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.
Having thus fully described our inven against rotation and retain said member in' either of two positions, a key adapted to be These grooves, at
inserted into said knuckle to engage the dog and move the same to its released position, said key being adapted for rotation in the knuckle to move the hinged member from one position to the other, and means projecting into the bore of the knuckle cooperating to be inserted into said knuckle to engage the dog and move the same to its released position, said key having a longitudinal bore to receive the pintle whereby, upon rotation of the key shank, said member is moved to one position or the other, and means in the bore of the knuckle cooperating with the key shank to prevent the extraction of the latter before the movement of said member to either position has been completed.
3. The combination with a hinged member having a rotatable pintle and a knuckle therefor, of a spring pressed locking dog mounted in the knuckle, said pintle having a longitudinal slot to normally receive said dog whereby the pintle is locked against rotation, said knuckle being provided'with a stud projecting into the bore thereof, and a key having a longitudinal bore to receive the pintle and provided with longitudinally extending peripheral grooves on opposite sides, the key shank being further provided with an annular groove with which the inner ends of said longitudinal grooves communicate, said key shank being adapted to be inserted into the knuckle and engaged with the locking dog to move the same to its released position and then turned to rotate the pintle and move the hinged member from one position to the other,said stud at the end of the turning movement being disposed in the annular groove of the key shank in line with one of the longitudinal grooves and acting to prevent the extraction of the key before the hinged member has been moved'to one position or the other;
In testimony whereof we hereunto afiix our signatures in the presence of two witnesses. I I
