COVERING FOR CABLE-CONDUITS.

SPECIFICATION forming part of Letters Patent No. 462,135, dated October 27, 1891.

Application filed April 23, 1891'.

To @ZZ whom it ritay concern:

Be it known that I, HARRY HUGHES, of Abilene, in the county of Dickinson and State of Kansas, have invented a new and Improved Covering for Cable Conduits, of which the following is a full, clear, and exact description.

The object of the invention is to provide a a new and improved covering which is simple and durable in construction, arranged to be opened by the pilot of the car, and adapted to be automatically closed by the same after the grip has passed.

The invention consists of a series of plates fitted to slide in angular bearings across the slot, and levers, each connected bya link with a plate and extendingin the path ofthe pilot at the next following plate. l

The invention also consists of certain parts and details and combinations of the same, as willbe described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of the improvement with parts removed and parts in section. Fig. 2 is a like view of the same in a different position. Fig. 3 is a sectional side elevation of the same. Fig. 4 is a transverse sect-ion of the same on the line 0c ot' Fig. 3, and Fig. 5 is a detail perspective view of two adjacent slid'- in g plates.

The cable-conduit A, of any approved construction, is provided in its top with the usual slot B, adapted to be covered by a series of plates C C C2 C3, dvc., arranged one in front of the other and iitted to slide transversely in a recess D, formed on top of the conduit A at one side of the slot B, as is plainly illustrated in the drawings. The recess D is adapted tobe closed on top by suitable covering-plates E, resting on the rabbets at the sides of the said recess.

Each of the plates C C C2 C3, &c.,is fitted to slide in bearings F, fixed in the recess D and arranged angularly to the slot, as is plainly7 illustrated in Figs. l and 2. The bearings F extend into angular recesses or grooves F in the said plate C C, ttc., so that the said plates in their transverse movement slide anseria No. 390,110. (No model.)

gularly to open and close the slot B. The ends G and G of each plate are arranged at angles to the bearings F, the t'ront end G of each plate being provided ou its outermost corner with a square offset G2 for a purpose hereinafter more fully described. This square offset G2 extends under a corresponding recess or notch in the end G of the preceding plate, as clearly shown in Figs 3 and 5, so that the plates can readily open and close without being hindered bythe said offset G2.

Each of the plates C C C2, &c.,is connected at its rear end G with a link H, extending under the next following plate and pivotally connected with a lever I, fulcruxned at I to the bottom of the recess D, as isplainly illustrated in Fig. Il. The front end I2 of the lever I extends into the slot Band is adapted to be engaged by a pilot J, secured tothe under side of the car K in front of the grip L.

The operation is as follows: The several plates C C C2 C3, 8:0., in their normal position close the slot D, and when the car K travels forward in the direction of the arrow a the pilot J engages the first plate C at the projection G2 of the front corner, so that a pressure is exerted on this plate, which is thereby caused to slide transversely in its angular bearings F. This movement of the plate opens the slot for the passage of the grip L, and the plate thus opened remains openfor a short time-that is, until the pilot J has opened in a similar manner the next following plate and travels a little past the lniddle of the said plate, when it engages the projecting end 12 of the lever I, so that the latterreceives a swinging motion in the direction of the arrow b', whereby the link H is pushed backward, thereby causing the plate C first opened to slide transversely to its former position, so as to close the slot B. This operation is repeated with the successive plates-that is, a preceding plate is closed when the pilot-J has traveled to about the middle of the' following plate, at which the lever I, operating the preceding plate, is engaged and actuated by the pilot J. Thus it will be seen that the slot B remains closed at all times after the car has passed, so as to prevent injury to animals or vehicles by being caught in the said slot B. The pilotJ is preferably held detachably on the car K,.so that TOO it can be moved to either side of the grip L Whenever the car is turned or travels on the return trip. It Will further be seen that n0 springs Whatever are required for accomplishing the movement of4 the plates C, doe., the latter being actuated by direct and positive mechanism.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

l. A covering for cable-conduits, provided with a series of plates fitted to slidein angular bearings across tlie conduit-slot, the said plates being opened and closed by a pilot held on the car, substantially as shown and described.

2. In a covering for cable-conduits, the cornloination, with a seriesof horizontally-sliding plates adapted to be moved from over the slot ofthe conduit, by a pilot on the car engaging the plates, of levers connected with said plates for engagement with the pilot for moving.A the plates across said slot, substantiallyl as described.

3. In a covering for cable-conduits, the combination, with a series of plates, of angular bearings in which the said plates are fitted to slide to open and close the conduit-slot, alink pivotally connected with a plate at the rear end, and a lever pivotally connected with the said link and extending at its free end into the conduit-slot in the path of a pilot on the car, substantially as shown and described.

4.` Ina covering t'or cable-con duits, the combination, with IiXed angular bearings, of a series of plates fitted to slide in the said angular bearings to open and close the conduitslot, each plate being formed with angular ends, a link pivotally connected with the rear end of each plate, and a lever pivotallyconnected with each link and arranged under the next following plate and having its free end extended into the cond uit-slot to be engaged by a pilot on the car to close the preceding plate, substantiallyas shown and,l described.
