GUARD-RAIL FASTENING FOR RAILROADS.
Application filed January 7, 1909.
Specification of Letters Patent.
Patented March 23, 1909.
Serial No. 471,180.
T0 all whom 'it may concern.'
Be it known that I, JAMES J osnrn ODoN- NELL, a citizen of the United States, residin 3f at Paducah, in the county of McCracken and State of Kentucky, have invented a new and useful Guard-Rail Fastening for Railroads, of which the following is a specication.
The invention relates to improvements in guard rail fastenings for railroads.
The object of the present invention is to improve the construction of guard rail fastenings, and to provide a simple and compaia tively inexpensive guard rail fastening of great strength and durability, capable of securely holding a guard rail and of eiiectually preventing the same from spreading or otherwise moving, whereby all liability of a train jumping the track at a frog is eliminated.
/Vith these and otherpobjects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawing: Figure 1 is a plan view of a portion of a guard rail fastening, constructed in accordance with this invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a similar view, taken substantially on the line 3-3 of Fig. 1. Fig. 4 is a plan view, illustrating a modification of the invention, the locking devices being located at the outer sides of the wedges. Fig. 5 is a sectional view of the same, taken on the line 5-5 of Fig. 4. Fig. G is a detail view of a portion of the clamp shown in Figs. 4 and 5. Fig. 7 is a vertical sectional view, illustrating another form of the invention, the locking devices being mounted within the wedge. Fig. 8 is a reverse plan view of the wedge and the locking device, illustrated in Fig. 7. Fig. 9 is a lan view, illustrating the manner of adjustaFly locking the wedge in place by means ofa key. Figs. l() and l1 are detail views, illustrating another modification of the invention, the locking device being arranged within the wedge. Fig. 12 is a detail view of another form of the locking device.
[ adapted to engage the clamp.
responding parts in all the figures of the drawing.
rThe guard rail fastening comprises in its construction a clamp 1, constructed of suitable metal and having upwardly extending end portions forming arms or jaws 2. The clamp is provided between the arms or jaws 2 with a flat upper face forming rail seats 3, located at opposite sides of an approximately T-shaped rail-engaging head 4, interposed between rails 5 and engaging the adjacent bottom ilanges thereof and the webs of the same at the inner faces of the latter, as clearly illustrated in Fig. 2 of the drawing. The head is formed integral with the clamp and the rails are thereby rigidly interloeked with the saine.
The arms or jaws 2 extend upward to substantially the plane of the treads of the rails, and are provided in their inner faces or portions with horizontal recesses 6 for the reception of webs 7 of wedges 8. The wedges 8, which are tapered longitudinally, have their inner faces 9 conforming to the configuration of the rails and fitting against the heads, the webs and the bottom flanges of the same, whereby the rails are firmly supported and held against outward movement. 'lhe wedges have their upper faces or edges arranged in the plane of the upper faces of the jaws or arms 2, and the webs 7 by fitting in the recesses 6 of the said jaws or arms interlock the wedges with the clamp. The rails, when properly engaged by the wedges, are maintained in their interlocking relation with the clamp and there is no liability of the rails spreading or otherwise moving, whereby a train is effcctually prevented from jumping the track at a frog.
In the form of the invention illustrated in Figs. 1 to 3 inclusive, the wedges are locked in engagement with the rails by means of cam-shaped dogs 10, operating in slots 1l of the webs of the wedges'and extending longitudinally of the same. The dogs are provided at their outer ends with recesses 11, fitting pivots 12 of the webs, whereby the dogs are pivotally connected with the wedges. The end portions of the webs are rounded at the outer ends of the slots 11 to form the said pivots 12. The inner ends of the wedges are provided with curved engaging edges, equipped with teeth 13, which are The wedges Like numerals of reference designate corl are reversely arranged, and the clamp is prolGO vided at opposite sides with projecting teeth 14. The pivoted dogs Aform gravity locking devices and automatically engage the clamps as the wedges are driven into place, and they eiiectually prevent the wedges from accidentally becoming unfastened. The recesses 11a form a detachable connection between the dogs and the wedges and enable the parts to be readily separated and assembled. It desired, the metal at opposite sides of the recesses 11a may be com pressed or pinched after the parts are assembled to retain them in such relation.
In Figs. 4 to 6 inclusive ofthe drawing, the locking device 15 is in the form of a pivoted dog, located at the outer edge of the web of the wedge and connected to the same by a screw or pin 16 and provided at its lower face with teeth 17, adapted to engage teeth 18 formed in the recesses of the arms or jaws of the clamp. rll'he dogs 15 are adapted to swing upward out of engagement with the teeth 18, and they form gravity locking devices for engaging the clamps as the wedges are driven into place.
In Figs. 7 and 8, the wedges are equipped with a pivoted dog 19, arranged within a longitudinal recess 20 of the web portion of the wedge and provided at its lower edge with teeth 21, adapted to engage a tooth 22 of the clamp. rI`he dog 19 is provided at one end with a head having a recess 23 for the reception of a rounded pivot portion 24 of the wedge. rI`his construction forms a gravity lock and enables the dog 19 to be readily applied to and removedlfrom the wedge.
In Figs. 10 and 11, the locking dog 25 also operates in a longitudinal recess 26 of the web portion of the wedge and is provided at its lower edge or face with teeth for engaging a tooth 27 of the clamp. One end of the dog is provided with a head 28, rounded to form opposite pivots and operating in a suitable bearing 29 of the wedge. The bearing is formed by recessing the wedge and forms a detachable connection between the dog and the wedge.
In Fig. 9 of the drawing, the wedge is equipped with a plurality of slots 31, located at different distances from the ends of the wedge and adapted to receive a key 32, which engages the clamp. A key 33 may also be used to supplement the locking devices heretofore described, as illustrated in Figs. 4 and 5 of the drawing, and it will increase the eliiciency of the guard rail iastenings. jHaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:-
