CONSTRUCTION OF CABLE- RAILROADS.

SPECIFICATION formingpart of Letters Patent No. 237,814, dated February 15, 1881.

Application filed December 11, 1880.

To all whom it may concern:

Be it known that I, HENRY OAsEBoLT, of

i the city and county of San Francisco, and State of California, have invented certain Improvements in the Construction of Endless Gable- Ways and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a perspective view of one of the cast-iron brackets used in my improved construction. Fig. 2 is a plan view of the same. Fig. 3 is a face View of the same, showing the end of the tie and slot-rail in position. Fig.4 is a vertical longitudinal section through the line 00 w of Fig. 2. Fig. 5 is a perspective view of the frame-work for the tunnel and track. Fig. 6 is a vertical cross-section of the same.

In all cable-ways for the transportation of street-railway cars by means of an endless traveling cable laid under ground it is highly desirableto have theedges of the slot through, which the gripe-shank passes adjustable to and" from each other, in order to compensate for unequal wear, warping of the slot-rails, or,

when occasion requires, to raise the cable through the slot and above the surface. It is also desirable to construct the slot-rails in the most economical manner and still retain great strength, and the purpose of my invention is to attain these objects.

My invention consists, first,in an adjustable cast-iron bracket secured to the ties and supporting the slot-rails; secondly, in a flat slotrail rolled with a heavy bead or rib on one edge; and, thirdly, in certain details of construction, as hereinafter more fully described and claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, J J are the foundationtimbers, which are laid at the bottom of the trench into which is to be built the tube or tunnel, these timbers J being provided with ribs K, to sustain the thrust of the sheathing, as hereinafter set forth. Upon J rest posts L, which, in turn, support the ties B B, on

(No model.)

which rest the stringers N N to receive the rail 0. The distance between the posts L L and the ends of the ties determines the width of the tunnel opposite their respective positions.

Upon the end of each tie is a cast-iron bracket, A, projecting over the end of the tie toward the central line of the tunnel. The faces of these brackets sustain the slot-rails H H, which are left sufficiently far apart to form a slot, R, for the passage of the shank of the griper. The brackets A are cast with slots D, through which pass bolts 0, to secure them to the ties, and with holes, through which pass bolts I, to fasten to them the slot-rails, and on their faces they have projecting ledges i 1, upon which rest the lower edges of the slotrails, and on the sides adjacent to the lowest points of their faces are right-angle-triangnlar lugs a, to receive and sustain the ends of angle-iron stringers P, the upper edge of the angle-iron stringer resting against the lower edge of the slot-rails H, to prevent the entrance of dirt into the tunnel.

The verticallyarranged planks S, which form the body of the tunnel, have their lower ends resting against ribsK on thefoundationtimbers, and their upper ends rest against the angle-iron stringers PP. The side surfaces of the brackets, ties, and posts are all in line, and consequently the edges of the planks S set close against all of them, and leave no openings for the earth to enter the tunnel when the framework is covered.

Experiment teaches me that the form of slotrail shown, having the heavy rib O and the downwardly-projectin g web or flange 19, embodies great wearing capacity, ease of fastening, and economy of production. I describe this slot-rail with the heavy rib O, in contradistinction to the slot-rails heretofore used, made of angle-iron rolled for the purpose, which are liable to be mashed down along the edges of the slot, whereas my slot-rail is in form the same with the ordinary commercial flat rail used for street-railroads, and the heavy rib offers a resistance to the wheels of heavy vehicles that prevents any distortion at the edges of the slot. The slots D in the brackets A allow an amount of longitudinal movement which to the same extent moves the attached slot-rails H, and consequently increases or diminishes the width of the slot upon bolts C being loosened up and the bracket forced forward or rearward.

5 Hatingt-hus described inyinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cable-wireway, the adj ustahle brackets A, adapted to sustain the slot-rails at- IO taehed to and in combination with the ties B,

for the purpose set forth.

2. In combination with a tunnel adapted to contain a cable for an endless wireway, the

slot-rails H, having a heavy rib, O, and a depending web, 1), substantially as described, for 15 the purpose set forth.

3. The bracket A, provided with lugs (Ht, in combination with the angle-iron stringer P, substantially as and for thepurpose described.

In witness whereof I have hereunto set my 20 hand.

HENRY GASEBOLT.
