CHARLES E. MGILREEVY, OF CHICAGO, ILLINOIS.
Application filed April 29, 1925.
My present invention relates to locking devices and has more particular reference to a lock that may be readily applied to a pin in a railway brake mechanism so that the latter may be prevented from accidental dislodgment.
The primary object of this invention is to provide a novel lock device so constructed that it mayv be readily applied to the brake pin subsequent to the latter being inserted into or through the part-s it isv designed to pivotally secure together. The present structure is made from a single piece of material that is bent the desired sha-peso that it may be manufactured at an economical iigure and sold for a reasonable price. My locking device is so constructed that it is capable of being mounted upon the pin wit-hout the use of tools and it may be readily removed therefrom by merely springing the jaws or arms open to permit a separation wide enough for the passage of the shank.
of the pin.
lVith the foregoing objects in view, I prey fer to carry out my invention in substantially the manner hereinafter fully described and asl more particularly pointed out in the claims, reference being now made to the accompanying drawings that form a part of this specification.
In the drawings :f
Fig. l is a top plan of two brake operating members pivotally connected by a brake pin and showing the application of my locking device thereto.
Fig. 2 is a vertical elevation looking at the side of the structure illustrated in Fig. 1.
Figure 3 is an end elevation of the said structure.
Fig. et is an elevation of the locking device detached from the brake-pin and other parts and looking at the device from the side opposite that illustrated in Fig. 2.
In the drawings I have illustrated a typical or preferred embodiment of my invention, and I have employed similar reference characters to designate like parts wherever the same appear throughout the several views.
Referring first to Figs. 1, 2, and 3, there is shown arod or bar A having a forked or bifurcated end between the spaced members B, B, of which is the enlarged head or eye C of a second rod or bar. The members B. B., of the fork or bifurcation are pro- Scrial No. 26,801.
aline with each other and register with a perforation El made transversely through the head or eye C, so that the two parts may be pivotally connected by the shank F of a transverse brake-pin having a head Gr, all in detail in the aforesaid figures of the drawing.
The locking device which I have designed for maintaining the brake-pin against accidental displacement is shown in the detached detail, Fig. 4, and consists of a length of flattened wire or metal that is first looped intermediate its ends to provide the substantially U-shaped end portion 5 the parallel arms of which, when the device is in position, extend across the face of the head G of the pin. parallel members 6, 6, ofthe U-shaped portion continue in parallelism but are bent rearwardly at 7 so that there is an obliquely 7 disposed section 8 that clears the head G The upper stretches of the .i
CIK
of the pin and the adjacent member B of..
the forked end of the rod A as seen in Figs.
l and 3 of the drawings. ,v
These parallel members 6, 6 are given a cownward bend at 9 so as to provide a vertical section 10 that is ina plane parallel .y
to the plane of the front or outside members 6, so that when the structure is viewed edgewise, as in 3, the same comprises outer and inner parallel sections that are connected at their upper ends by an oblique bridge thus providing an element of inverted U-shape. Preferably intermediate the upper and lower ends of the vertical rear portion of the device the two lengths of metal are bowed away from each other in concavo-convex curves l1 to provide between these bowed portions a substantially circular pocket or seat12 to receive the shank F of the brake pin when the vertical rear section is inserted between the head or eye C of the second rod and the adjacent member B of the bifurcation.
The lock device is preferably placed in position manually, without the aid of tools, and in order that the same may be readily engaged with the shank of the pin I havel bent the lower end of the pieces outwardly away from each other as at 13 so that there is provided an entrance passage-way 14 that is widest at its outer lower end and tapers inwardly and upwardly towards and into the pocket or seat 12 for the brake pin shank F.
When the device is to be inserted on the vided with transverse perforation@ l.) that pin the rear vertical Section is placed tween the head or eye C and an adjacent member B of the Vfork or bifurcation with the outwardly bent or flared ends 13 (which in reality provide a bifurcated end for the lock device) engaged with or straddling-` the adjacent segment of the pin. rihe front or outer vertical section of the device will be in front of the plane or the head Cv of the pin, and upon the device being pushed towards the axis of the pin, the birurcated end will separate thus widening the mouth of the passageway la and permit the pocket or seat 12 to receive the pin between its opposite members. Due to the springy nature o'l' the metal and its peculiar formation, that is, its construction in practically two halves joined by a single piece at the lower end of the Ushaped liront section, the parts 13 will readily 'open to permit the passage of the pin. After the device is in positionL it will be so disposed that the pin is prevented from being moved longitudinallj,Y and therefore may not be accidentally displaced but when it is necessary to remove the pin this may be done by spreading the ends 13 outwardly and drawingl the lock oil'l the pin by an outward radial movement with respect to the axis of the pin.
Modiiications or retinenieuts oi' the disclosed structure are possible and desire it understood that such are fully comprehended within the scope of the appended claims.
'Vhat l claim as new is 1. A brake-pin locking device comprising a 'U-shaped spring wire the end portions ot the wire opposite the bight 'portion being,- oppositely bowed to provide a pocket to receive the shank ot the pin, 'and said structure being provided, intermediate the bight and the bowed portions, with a return bend whereby to position the bight portion opposite said pocket to engage the head of the pm.
2. A locking device comprising a length of metal looped upon itself mediate its ends to provide a flat'double element and the looped structure bent transversely into a U-shape the arms of which have spaced side by side members, the end portions ot the two members havingv alined apertures and a pin inserted.Y
through said apertures to pivotally connect said members, of a locking device consisting of a length of metal provided with two Ushaped bends at substantially right angles to each. other, one of the arms of the second lul-shaped bend being positioned across an end ot' said pin, the other arm having its two parts bowed outwardly to provide a pin receiving,l pocket open to the end of the arm whereby the parts adjacent the pocket are adapted to be sprung,` away from. each other and assembled with the pin subsequentI to the latter beingv inserted in the apertures of said members.
A brak@ pin locking device comprising` a. U-shaped spring wire formed intermediate its spaced ends and its bight portion with a return bend whereby to position the bight portion alongside the spaced ends, the spaced ends being formed with opposite vbows to provide a pocket to receive the shank of the pin and the-n extending' away from `each other to provide 4an open passageway for ready access to the pocket into which the shank ot the pin to be locked may be inserted transversely between the spaced ends.
