- DRAW-HooK FOR STREET-CARS.

:SPECIFICATION forming part of Letters Patent No. 351,793, dated Novemberk 2. 1,886.

` Application led February 10, 1886. Serial No. 191,475. (No model.)

To all whom t may concern:

Be it known that I, AUGUST Barr, a citzen of the United States, residing at the village of Pullman, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draw-Hooks and Springs therefor, for which I desire to obtain patents in the United States, of which the following is a specification.

It has been usual heretofore to place the draw-bars and the draft-hooks underneath the street-cars, and to cause the draftstrain to come directly upon the spring. This construction has the double disadvantage of throwing the points of attachment to the car too low and of necessitating a'direct pull upon the spring, the latter feature causing, inpraetice, considerable inequality in the draft-pull upon the car.

My invention has for its object the devising of means for giving the draft-hook a higher position and also effecting an indirect action of the spring upon the draftstrain. `To this end I propose to dispense entirely with the drawbar, using instead thereof a lever pivoted to the nose-piece of the platform and carrying at its upper end the draft-hook, which is thus suitably elevated, and bearing at its lower end against a head-block moving in guideways pivoted to the bottom of the car, against a spring.

My invention further consists in means for preventing the escape of the clevis from the draft-hook, which can be operated by the driver without reaching over the dash-board.

My invention further consists of certain details of construction, hereinafter fully described and pointed out in the claims. I

In the drawings hereto annexed and forming a part of this specification, Figure l represents a front elevation of the nose-piece and Y dashboard of a street-car to which my inventions have been applied. Fig. 2 is aside view, partlyin asection, of the same. Fig. 3 is a bottom view giving a section of the spring headblocks and guard-pieces ou line 3 3 of Fig. 2.

The two castings C, of shape shown in Figs. 1 and 2, are attached by bolts K to the nose-piece A at a suitable distance on each side, respectively, of the center thereof, and carrya pivotal bolt, H, upon which is hung the vertical lever1 D, provided at its upper end with a draft-hook, and having at its lower end, on its inner side, a rounded face, I, which bears upon the headblock G of the spring F. Thelever D is made of the shape shown, so that when under no strain its lower end is pressed out by the spring F and the inner edge of its upper part rests against the dashboard C, and when strain is applied to the draft-hook -it is free to take the position shown in the dotted lines in Fig. 2, compressing the spring F against its rear head-block L. rIhe head-bloeks G and L are curved above and below, as shown partially in dotted outline in Fig. 1, and have lateral extensions S and Q, Fig. 1, which tit in grooves formed in the guide-pieces E E, and are also attached by bolts K to the nose-piece. The head-blocks have inwardly-extending circular lugs R R for retainingthe spiral spring F in its position.

It will of course be understood that my invention is not limited to the particular form of spring hereinI shown, or the particular form of mounting therefor, as an unlimited variety lof spring-bearings for the lower end of the draft-lever might be very readily devised. Neither do I confine myself to the particular .of my invention lying in the use of the lever intermediate between the draft-hook and the draft-spring.

The device which I have invented for preventing the escape of the clevis from the drafthooks consists of a clip, O, attached to a pivotal bolt, I?, and having a pin, T, passing through the said bolt to prevent the slipping of the clip on the bolt, the said bolt P passing through the dashboard and having at its inner end a handle, N, similarly attached to it by a pin.

turned from the inside of the dashboard the clip O will follow it, and thus can be readily thrown by the driver to and from its closing position with reference to the draft-hook.

1. In a street-car, the combination of a pivoted lever provided with a draft-hookat one end, a spring mounted between sliding headposition of the draft-lever shown, the essence It isobvious that when the handle N is y IOO catch for closing the entrance to the same on the outside of the dashboard of the car, a 15 handle inside of the dash-board, and a bolt passing through the dash-board and rigidly connected to both the catch and the handle, whereby the catch can be moved to and iro from the inside of the dash-board, substan- 2o tially as described :1nd shown.

AUGUST RAPP.
