GRIP-SLOT CLOSER FOR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 345.594, dated July 13, 1886.

Application filed February 10, 1886. Serial No. 191,478.

To all whom it may concern,

Be it known that I, LINNAEUS O. J ENNINGs, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Grip-Slot Closer for Cable Railways, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a top view. Fig. 2 is a transverse section at 2 2, Fig. 3. Fig. 3 is an enlarged top view. Fig. 4 is an enlarged outside, and Fig. 5am inside elevation.

The invention relates to means, hereinafter fully described, for securing to the sides ofthe grip-slot railswhich have a limited transverse movement, and whose edges are held together by springs when not forced open by the grip-shank. By use of the closer I am enabled to make the slot wider, so as to allow the use of a grip'shank of greater thickness than would be otherwise admissible, as an open slot is an element of danger in a street, the danger increasing as the width of the slot increases. This has necessitated making the grip-shank thin, so. as to move freely in a narrow slot. Of course, as the shank was made thinner, it was necessary to make it broader, and this made it unsuited to the short forming the sides of the slot. Upon the flanges B lie the movable closing rails O, which in their normal position, as seen in Figs. 2 and 3, close the grip-slot D. The rails are held in place by stud-bolts E, which are screwed into or otherwise attached to the under sides of the (No model.)

rails O. The shanks of. the stud-bolts work in transverse slots b of theflanges, the slots having suflicient length to allow the rails Oto move outward as they are forced asunder by the shank F of the grip in passing. The heads e of the stud-bolts extend beneath the flanges B at each side of the slots b, so as to hold the rails 0 down. The heads 6 have transverse holes, through which pass loosely studs G, which are fixed in the sides A. Surrounding the studs G, between the sides A and the heads 6, are spiral springs H, whose office is to force the edges of the rails 0 together over the grip-slot D. The ends of the rails C have interlocking tongues c and recesses c, forming a hinge-connection allowing a very limited movement of the rails upon each other at these points.

I claim as my invention-- 1. The combination of rails or flanges forming the sides of the grip-slot in a cable railway, orifices therein for the passage of studs, closingrailslying on the flanges, with studs extending from their under sides through the orifices of the flanges, studs fixed in the sides of the cable-conduit, extending into orifices of the rail-studs, and springs bearing against the rail-studs,forci'ng the meeting edges of the closing-rails together.

2. The combination, in a cable railway, of closing-railslying over the slot rails orflanges, having transverse horizontal movement thereon, jointed together at the ends, and having studs extending through orifices in the slotrails, and having heads extending beyond the edges of the orifices, studs extending from the sides of the cable-conduit into holes in the stud-heads, and springs bearing against the stud-heads, for the purpose set forth.
