NUT -LOC K.
SPECIFICATION forming part of Letters Patent No. 478,637, dated July 12, 1892. Application filed November 80, 1891. Serial No. 413,548. (No model.)
To all whom it may concern:
Be it known that I, JOHN PUTMAN, a citizen of the United States, residing at Cerro Gordo, in the county of Pratt and State of Illinois, have invented a new and useful Nut- Lock, of which the following is a specification.
The invention relates to improvements in nut-locks for rail-joints.
The object of the present invention is to securely lock the nuts at a rail-joint and to support the meeting ends of the rails.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.
In the drawings, Figure 1 is a perspective view of a rail-joint provided with a nut-lock constructed in accordance with thisinvention. Fig. 2 is a horizontal sectional view. Fig. 3 is a transverse sectional view. Fig. 4: is a detail perspective View of alocking-plate. Fig. 5 is a'similar view of the supplemental locking-plate. Y
Like numerals of reference indicate corresponding parts in all the figures of the drawlngs.
1 1 designate rails connected by fish-plates 2 and 3 and secured to the fish-plates by horizontal bolts 4, passing through openings in the webs of the rails and the fish-plates. The meeting ends of the rails are supported by a truss-plate 5, arranged beneath the rails and spanning the space between cross-ties and provided with an inclined flange 7, arranged on the outer side of the rails and extending upward flush with the tread of the rails. The inclined flange 7 extends within a short distance of the ends of the truss-plate and is provided with elongated bolt-openings arranged so that the nuts 8 may be screwed square against the fish-plate 2.
The nuts 8 are locked against turning by a plate 9, provided with a series of rectangular openings to receive the nuts, and these nutopenings 10 are elongated sufliciently to permit any contraction or expansion and also to adapt the plate to the arrangement of the bolts. The locking-plate is provided with a horizontal slot 11, communicating with a verticallyelongated bolt-opening 12, adapted for the reception of one of the bolts for securing the locking-plate 9 in place. The nut of this securing-bolt is locked by a supplemental plate 13, having a shoulder let to engage one side of said nut and provided on its inner face with a lug 15, projecting beyond the shoulder and adapted to enter the slot 11 and engage the lower face of the nut of the securing-bolt. The supplemental locking-plate is further secured by a key 16, arranged in a perforation of a lug 17 and engaging curved notches 18 of a supplemental plate. The perforated lug 17 is formed integral with the locking-plate 9, and the supplemental locking-plate is bifurcated at 19 to receive the lug 17. It will be seen that a rail-joint is supported and that the nuts at the same time are securely locked against turning.
What I claim is- The combination, with the rails, fish-plates connecting the rails, bolts securing the fishplates to the rails, and nuts arranged on the bolts, of the locking-plate provided with a bolt opening, a slot communicating with the opening, and an integral perforated lug, said locking-plate having a series of nut-openings, a supplemental plate having a shoulder and provided with a lug adapted to enter said slot, said supplemental plate being bifurcated, to receive the perforated lug and provided with recesses, and a key arranged in the perforation of the lug and in the recesses of the supplemental plate, substantially as described.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
JOHN PUTMAN. lVitnesses:
