CABLE-CONDUIT.

PECIFICATION forming part of Letters Patent No. 335,553, dated February 2, 1886. Application tiled July 7, 1R85. Serial No. T0887. (No model.)

To a/ZZ whom, it may concern.-

Be it known that I, WILLIAM A. WRIGHT, a citizen of the United States, residing at Centreton, in the county of Burlington, State of New Jersey, have invented a new and useful Improvement in Cable Conduits, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 represents atop or plan view of the interior ofa cable-conduit embodying my invention. Fig. 2 represents a transverse vertical section thereof. Fig. 3 represents a vertical section in line a' x, Fig. 2. Fig. 4 representsatop view of a modification. Figs. 5 and 6 represent views of the grip employed for the conduit embodying my invention.

Similar letters of reference indicate correspending parts in the several figures.

My invention relates to improvements in cable-conduits; and it consists in a new con struction of sectional doors for covering the slot. Y

It also consists invprovidingmeans for se- 2 5 curing thecables at the crossings or on curves,

. so thatl power may be readily communicated to the car.

It also consists in providing the grip and side walls ofthe conduit with devices whereby said 3o grip is automatically operated at the commencement of the crossing and a rack thrown into engagement with devices communicating power to the ear; and, further, in details in the construction ofthe several parts thereof as hereinafter are fully set forth and described.

Referring to the drawings, A represents a cable-conduit which is formed ofside walls, B,

atop, C, and a bottom, D, said ltop having a 4o slot, E, which is normally closed by doors F. Projecting from the outer sides of the walls B are ledges E', which are inclined from the bottoni upwardly and outwardly, whereby the superimposed weight of the earth, paving. etc.,

bearing against said ledges serves to press the sections ofthe top Gin opposite directions, and prevent the closing ofthe slot. The doors F are hinged to one section of the top and close on the other section, and are continuous, hav- 5o Ing diagonal ends, whereby they may be raised without abruptness, the raising being accompulleys J, which are operated bythe running cable K and bevel-wheels L, which are connectcd with said pulleys and geared together in such manner that the wheels are rotated i n the same direction. Connected with the grip is a rack or tooth, M, whichis so disposed that 'when it reaches tl -e first pulley J itis adapted to engage with the adjacent wheel L and receive power therefrom, the same being communicated to the car.

In Fig. 3 the cable K is shown at the place of a crossing eableVK', said cable K being depressed'J and guided under a pulley, N, the gearingL and pulleysJ having horizontal axes. In this case when the grip of the car reaches the first pulley J, the rack meshes with the adjacent wheel L, the grip having been duly loosened from the cable. The rack M, owing to its length, is carried along to the next wheel L and successively to the other wheels L. When the rack clears the last gear-wheel, the grip is tightened, and the caris again propelled by the cable, it being noticed that the grip has been carried over the crossing cable without stopping the car.

ln Fig. 4 the cable is shown adapted for a curve, corner oi.' a street or road, &c. In this case pulleys N are interposed between the pulleys J, the cable extending i n zigzag directions. The axes ol' the several pulleys are vertical, and the pulleys are geared with the wheels L by means of bevel-wheels L', so that the power of the pulleys J is communicated tothe wheels L, which, being geared together and succes sively engaged by the rack of the grip, cause the propulsion ofthe car around theI curve or corner while the grip is disconnected from the cable. The rack or tooth M is connected with the movable jaw of the grip, which latter has a slide, 1t, provided with a rack and operated has at itslower end which works in a slotby the lever S. The slide an inclined portion, R',

IOO

ltally inward from the side wall ofthe conduit f' is an arm, l?, somewhat cam-shaped or double inclined, and so disposed that when the grip approaches the first wheel L, should the opening of the grip be neglected, a projection, Q, on the movable jaw ofthe grip strikes the arm P in such manner that said jaw is forced ont and the grip accordingly opened, the rack M, as is evident, being thrown into engagement with the wheel L.

If desired, a motor may be employed for operating` the wheels L.

Having thus described my invention,wl'iatl claim as new, and desire to secure by Letters Patent, ish

1. A cable conduit having a slot,and hinged doors having diagonal ends closing thel saine, substantially as and for the purpose set forth.

2. A cable-conduit having a slot, and hinged doors having diagonal ends, in combination with a grip provided with a shoe, substantially as and for the purpose set forth.

3. In a cable-conduit, the bevel gear-wheel L and pulleys, in combination With cable K and grip H, having rack M, substantially as and for the purpose set forth.

4. The pulleys J and bevel gear-wheel L, in combination with cable. K, pulley N, grip H, having a pivoted jaw carrying rack M, snbstantially as and for the purpose set forth.

5. In a cable-conduit, an inner horizontal 4o arm, P, in combination with grip H, havnga pivoted jaw, the latter having a projection, Q, and rack M, substantially as and for the purpose set forth.

6. The grip l-I, having a movablejaw with a slotted attachment, and a slide in said grip having a rack operated by a lever, the said slide being provided with an inclined portion working in the said slotted attachment and adapted to operate thesaid movable jaw, sub- 5o stantiall y as and for the purpose set forth.
