UNITED STATES WILLIAM JOHN GEESON, 0F IHOROLD, ONTARIO, CANADA.
RAILWAY CLAMP.
Application filed July 7,
T 0 all whom it may concern:
Be it known that I, \VILLIAM J OHN Gen SON, of Thor-old, in the county of Welland, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Railway Clamps, of which the following is a specification.
This invention relates to devices such as are secured to railway rails to act as bumpers for the wheels to prevent the movement of cars past a given point, and my object is to devise a construction which is. simple to manufacture, easy to place in position and remove, but strong and effective.
I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of one form of my improved stop;
Fig. 2 a cross section on the line 22 in Fig. l;
Fig. 3 a plan view of the device; and
Fig. et a rear elevation of another form of the stop. I
My device comprises a body 1 provided with a pair of depending legs 2 and 3 and adapted to straddle the rail, each of said legs being provided with a recess at to receive the head of the rail. The recess in the leg 3, however, is of such a depth and shape that when the body is rocked sidewise, the bottom of the leg 2 will clear the edge of the head of the rail so that the device may be removed.
To retain the device firmly in position a slot 5 is formed through the body for the passage of a wedge 6. The wedge 6 is preferably provided with one or more holes for the insertion of a pin 7 to prevent the accidental withdrawal of the wedge.
At least the central portion of the slot 5 is curved longitudinally, forming a rib 8 transversely of the slot midway between the legs, against which the wedge bears. It will thus be seen that when driving the wedge it engagcsthe head of the rail and the rib 8, and therefore any strain on the legs is exerted substantially equally between them.
In Fig. 'l- I show the leg 2as being of greater length than ,in the construction shown in Figs; 1 to 3, and the recess 4 therein of much greater width. A retainer 9 is inserted in the recess below the head. of
1924. Serial No. 724,726.
the rail. With this arrangement it is unnecessary to have the special proportioning of the recess in the leg 3 referred to above. as by removing the retainer 9, the body may be rocked to one side to permit the removal of the device.
The body 1 is also preferably provided with a handle 10. Formed at one end of the body are vertical guides 11 in which guides is vertically movable the bumper member 12. A removable member 13, held in place by cap screws 14, normally retains the bumper member 12 in position in the guides.
At opposite sides of the bumper member 12 are provided depending projections 15, which engage opposite sides of the head of the rail and assist in keeping the device in position on the rail.
In some cases the bumper member 12 may be omitted and a tie or block of wood may be placed across the rails in front of the stops, as ordinarily two of these will be used, one on each rail.
The bumper member 12 may, if preferred,
be formed integral with the body, and in.
this case it is not necessary that the legs 2 and 3 be as wide as the body, and the portions 16, indicated in dotted lines, may be omitted.
From the above description it will be seen that I have devised a rail stop which will. satisfactorily attain the object of my invention as set out in the preamble of the specitication.
What I claim is:
1. In a rail stop, the combination of a body having integral therewith a pair of depending legs directly opposite one another and adapted to straddle the rail, each of said legs having a recess therein to rcceive the sides of the head of the rail, one of said recesses being of greater depth than the head of the rail whereby by rocking the body transversely of the rail it maybe removed therefrom, said body having a slot formed in its under side; and a wedge in said slot engaging the head of the rail and adapted to exert a perpendicular lift elfect to engage the under side of one of said recesses with the headof the rail.
2. In a rail stop, the combination of a body having integral therewith a: pair ofdepending'legs directly opposite oneanother and adapted to straddle the rail, each of said legs having a recess therein to receive the sides of the head of the rail, one oi said recesses being of greater depth than the head of the rail whereby by rocking the body transversely of the rail it may be removed therefrom, said body having a slot formed in its under side transversely of the rail and substantially centrally of the legs; and a Wedge in said slot engaging the head of the rail and adapted to exert a perpendicular lift effect to engage the under side of one of said recesses with the head of the rail.
3. In a rail stop, the combination of a body having a pair of depending legs adapted to straddle the rail, each of said legs having a recess therein to receive the sides of the head of the rail, said body having a slot formed in its und r side;and a Wedge i sai slo eng ging he ad otth rail, on at said egs being longer than t e other a dthe rec the i o g a e Wi th than t e eces in the o er g; an a r tainer in said Wider recess below the head of the rail.
4. In a rail stop, the combination of a body having a pair of d pending legs adapted to straddle the rail, each of said legs having a recess therein to receive the sides of the head of the rail, said body having a slot formed in its under side; a rib being formed transversely of said slot substantially centrally of the body; and a Wedge in said slot engaging the head of the rail and said rib.
5. In a rail stop, the combination of a body having a pair of d pending legs adapted to straddle the rail, each of said legs having a recess therein to receive the sides of the head of the rail, said body having a slot formed in its under side, a rib being formed transversely of said slot sub stantially centrally of the body; and a wedge in said groove engaging the head of the rail and said rib, said 1' cesses being proportioned to permit the removal of the stop from the rail by removing the Wedge key and rocking the body to one side.
6. In, a rail stop, the combination of a body having a pair of depending legs adapted to straddle the rail, each of said legs having a recess therein to receive the sides of thehead of the rail, said body having a slot formed in its under side; a Wedge n sa d ot eng g g th head i the rai guides at. one end of said body; a d a removable bumper member support..d in said guides- 7-i n rai s p, th ombi at o a body having a pa r o d pending has d p to straddle-the. aiLe Qh'Ot sa d gs ha ing airec ss herein to. eceiv t f. ,7 said body liarin said slot rngaging the head of the rail; guides at one end of said body; and a removable bumper member supported. in said guides, said bumper member having a depending projection at each side to engage the sides of the head of the rail.

10. In a rail stop, the combination of a body having a pair of depending legs adapted to straddle therail, each of said legs having a recess therein to receive the sides of the head of the rail, said body having a slot form d in its under side; a Wedge in said slot engaging the head of the rail, one of said legs being longer than the other and the recess therein of greater Width than the recess in the other leg; a retainer in said Wider recess below the head of the rail; guides at on end of said body; and a removable bumper member supported in said guides.
11. In a rail stop, the combination of a body having a pair of depending legs adapted to straddle the rail,each of said legs having a recess therein to receive the sides of the head of the rail, said body'having a slot form d in its under side; a rib being formed transversely of said slot substantially centrally of the body; a Wedge in said slot engaging the head of the rail and said r n o d s ei g l nger than the other and a recess therein of greater wid h an. e re e n he o he 1 s; and a retainer in said Wider recess belon the headof the rail- Signed at Niagara Falls, (hit, this 17th d y. at un 24;-
