GEORGE B. BRYANT, OF PHILADELPHIA, PENNSYLVANIA.

CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 317,085, dated May 5, 1885.

Application filed March 19, 1885. (No model.)

To aZ'Z whom itmay concern:

Beit known that I, GEORGE B. BRYANT, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inventedcertain new and useful Improvements in Cable Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe artl to which it appertainsto make and use the same.

My invention relates to an improvement in cable railways, the object being to so construct a conduit or tunnel for the travel of the cable, and of such character that all danger of the slot-irons, between which the grip travels, being forced together by the weight of the earth upon them and upon theirsupports will be obviated, and thus prevent undue wear both upon the iron and grippers.

A further object of my invention is to provide simple, effective, and convenient means whereby the irons may easily and readily be forced toward or away from each other; and, further, to provide a device of this character which shall be simple and economical in construction and durable and efficient in use; and

with these ends in View my invention consists in certain novel features of construction and combinations of parts as will be hereinafter described, and pointed out in the claims.

In the accompanying` drawings, Figure 1 is a View in perspective of a portion of my improved conduit. -Fig 2 is a view thereof in cross-section, taken through one of the brackets. Fig. 3 is an enlarged view showing the :manner of adjusting the slot-irons, and Figs. 4, 5, and 6 are modifications thereof.

Arepresents one of the brackets supporting the rails B, said bracket consisting of a base, a, from the ends of which extend the inclined supports t, the said base and inclined supports being centrally provided with a ange, c, to increase the strength thereof. This flange c is extended upwardly from the base, and formed into vertical supports d, the upper ends of which are arched, as shown at c. From the upper ends of the supports?) extend the horizontal pieces f, which are also centrally provided with a Iiange, g, and are connected with the upper curved ends of the supports d, which latter are provided with flanges h on either side thereof, to which is bolted the sections of tubing C. On. the upper horizontal pieces, f, and at the outer ends thereof, are formed the upwardly-extending anges i, between which are located the beams J, to which latter are bolted the rails B, of any desired construction, the bolts securing the rails to the ward pressure of the earth, the tendency of the weight in this case on the supports and on the rails being to force apart the upper ends of the supports b, a great portion of the strain coming on the center of the base. In order to prevent breakage at this point, I have thickened the metal, as shown at Z, thereby greatly adding to the strength of the bracket at this point. These brackets are preferably'ma-de of cast-iron, and are formed in one piece, thereby adding to their strength and materially lessening the cost and nble in manufacturing the same.

To the inner ends of the horizontal pieces f are bolted the angle-irons E, the same fitting against the anges h, formed on the ends of the pieces f. The flanges serve to assist in keeping the irons in position. The irons are so arranged that the ends thereof on opposite sides meet on different brackets, in order that a smooth track will always be opposite a j oint in the opposite iron and prevent the gripper from getting caught between the irons.

On the inner sides of the supports d are formed the lugs m, adapted to serve as bearings for the ends of the shafts a, carrying a pulley, o, over which the cable is adapted to travel.

My invention is exceedingly simple in construction, the bracket being cast complete `in one piece, making it strong and durable and efficient, and also economical, the cost of manufacturing it being comparatively small.

The slot-irons E are provided with elon- IOO gated bolt-holes for the passage of the bolts E', which latter securely hold the slot-irons down on the brackets. These brackets are provided on 'their upper surfaces, about midway between the lips h and their outer edges, with the upwardly-projecting lugs II, the op- Psi/te side edges of which are beveled, as shown a L. a I is a rod provided at one end with an opening for the passage of a pin, e, and at a point near its outer end with a shoulder, i2, between which and the pin t" the vertical wall of the slot-irons rest, and by means of which the rod is securely fastened to said slot-iron. This rod is preferably enlarged at its outer end, and is provided on its lower face with a recess, j, having inclined end walls. This recess is larger than said lug, for the purpose of admitting wedges J to be introduced within the recess j on opposite sides of the lug H. Thus it will be seen that, by tapping on the small end of one wedge and the large end of the other wedge, the rod I can be moved longitudinally in either direction and carry with it the slotiron attached thereto.

In Fig. 4 the lug I-I is provided with an opening sufficiently large to admit ofthe passage of the outer end of the rod I. The rod I in this instance is provided with the recess on its upper surface, and the wedges J are intro- 1duced into the recess on opposite sides of the In Fig. 5 I have dispensed with the wedges shown in the previous figures, and provided the rod I with two downwardly-projecting lugs, each having a female screw-threaded opening for the passage of the screws K, the inner ends of which abut against the inner faces of the lugs II. By unscrewing one screw and screwing upon the other the rod I can be positively moved back and forth the required distance.

In Fig. 6 I have dispensed with one of the downwardly-projecting lugs on the rod I, (shown in Fig. 5,) and have provided the lug I-I witlan opening in which a screw, K', is swiveled. This screw passes through a screwthreaded opening in a single lug on the rod I, and is provided with a head by which it is turned. By turning the screw in one direction the slot-iron attached to the rod I is moved away from the slot-iron on the opposite side of the slot, and by turning it in the opposite direction the said slot-iron is moved toward the iron on the opposite side of the slot.

I make no claim in this application, broadly, for alfdevice for positively adjusting the slot-irons toward and away from each other, as the same forms the subject-matter of my application No. 139,259.

Having fully described my invention ,whatI claim as new, and desire to secure by Letters Patent, is-

l. The combination, with brackets constructed substantially as described and the tubing secured to the vertical walls of the brackets, of the rails, rail-supports, bolts securing the rails and rail-supports to the brackets, and slot-irons adjustably secured to said brackets, substantially as set forth.

2. The combination, with the bracket constructed substantially as described, and pro-- vided at its ends with the lugs forming the seat for the rail-support, and at its central portion on opposite sides of the slot with upwardly-projecting lips forming a limit of inward movement for the slot-irons, of slot-irons adjustably secured to the upper surface of the bracket on opposite sides of the slot, substantially as set forth.

3. The combination, with a bracket provided with upwardly-projecting lugs and slotirons secured on said brackets on opposite sides of the slot therein, of rods rigidly secured to the brackets, and provided with projections adapted to rest on opposite sides of the lugs, and devices bearing against said projections and the opposite faces of the lugs, and the brackets for moving the rods longitudinally in opposite directions, substantially as set forth.

et. The combination, with a bracket pro vided with upward-projecting lugs and slotirons secured on the brackets, of rods secured to the slot-irons, and provided with projections adapted to rest on opposite sides of the lugs, and wedges adapted to be inserted between said lugs and projections, substantially as shown.

5. The combination, with a bracket having upwardly-projecting lugs thereon, the latter being provided with beveled. faces, and slotirons secured to said brackets, of rods secured to the slot-irons, and provided with projections having beveled faces, and wedges inserted between the beveled faces of the lugs and projections, substantially as set forth. Y

6. The combination, with a bracket having upwardly-projecting lugs, the latter having openings formed therein, and slot-irons secured to said bracket, of rods secured to the slot-irons and passing through the openings in the lugs,and provided with proj ections,and wedges inserted between the lugs and projections, substantially as shown.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE B. BRYANT.
