GINIDEE-GAR.l` i I Be it'known that I, JOHN HARTiiiAN, a

' citizen of the United States, residing at 227 Gowen avenue, in the cityofv Philadelphia,

county o f Philadelphia, and State of; yPennsylvania, have invented certain new and useful Improvements in Cinder-Cars, whereof the following is a specification, reference being had to the accompanying drawino's.

My invention relates to that class of cars in lwhich the discharge or-dumping operation is' effected by rocking the car-body, the preferred construction being one in which the` ibottom surface of the body litself is curved,

so as'to rollupon the iooror'upper surface of Among the 'objects of my invention arethe following: To firmly seat the car-body in position during transit and to lock it in its normal position, to quickly and etlieiently rock the bodyfin either direction aiid'insure the l entire discharge of its contents atthe desired point, to avoid ythewdangei ofv-tippingthe.

. .body off from the frame by excessive Inovement, and toprevent injury to the actuating Y mechanism undrthe conditions of use.v

i l preferably vconstructed with the curved Iuri-,-

` Referring'to the drawings,I Figure Irepredersu'rfaceindicated at 2, the axis of the curve being longitudinal with the trucle, soy

Oni the under side of the frame 4 downwardly-projectingV lugs: 21 22 are ,arranged in proper relation to jsub; jacent bearing-points, such as the uppermost portions of the treads 10 of the several carwheels 11, the relation, however, being'siich that? when the frame 4 is in its normalI or central position the lugs are supportedlc'lear of the. bearing-points by the action ofthe springs 16 17.

When the car-body is in its normaler-central position, the rounded bottomsurface 2 thereof rests upon the twoilongitudinal.shoul-` dersl) 0,v asindieated atLFig. 1V, so that a` l relatively wide seat is afforded, vvhichtends to prevent the accidental rocking 4ofthe -car during transit. The carbody `ispipvided with the usual chains A24 25 to insure parallelism in its rocking movement. vf f The actuating mechanismwhereby the-cai'r is tilted orfroeked comprises alpaii-. of. rocking arnis 26 27, pivoted together atf29i' 'lhe longer arni Z6 is plvoted atits lower end to the fi'aine,'as indicated vat 3l. .'ll-ie upper end ofthe arm 27 is pivoted at 32 to.: the-carev central axis of the body when ii'i its normal position and at rest,` as vindicated iii Fig. I. The arm` 26 isconnected, by `Ineans of link 34, Withtlie pistonof a cylinder 35,lia'ving the-usual connections at 37 for the 'admission of iiuid underpressuire, suoli steamffrin theloconiotive=engine. f

Referring to the position of `tliepirts"indiev cated in the endview` of Fig; l, the'piston is body, thefpivotal points 31 32 beingyertically in line with each other'andWith-the at the extreme right-liaiidgeiid ofthe cylinder 35: in said figure, =it is obvious thattlieii'notion arins is'indicated as being at therightsland side or toward the cylinder; but it. is obvious that 4they-can be arranged ir 'the reveil-'sean? gular position-on the oppositefside ofithc. xis

and the spring 17 is compressed until the lug 22 rests upon the tread 1,0 of the car-wheel 11 on that side. reason'of the overhanging downwa'rd curve 13 of the iloor the car-body can be rocked into a position which insures the complete discharge of its contentsat a region well clear of the track.` The action of the spring 16 upon the side away from the discharge tends to assist the rocking movement. Thus in Fig. V as the body is rocked away from the central axes the center of gravity changes until a' point is reached where the relieved spring 16 exerts its force to Jfurther tilt the ioor in theright direction until the lug 22 brings up against its bearing point on the tread of the wheel 11. 'In order to prevent accidental displacement of the car-body until -the discharge is to be effected, I provide a locking mechanism which may be used in either the position oi'; the rocking arms. Upon each side of the center of the frame, at points which corres ond with the alternative positions of the roc ing-arm 26, are mounted brackets 39 39, having sockets 4() 40 adapted to receive the end of a screwbolt 41, (shown in Fig. IIL) engaging in a threaded cavity in the arm 26 and provided at its outer end with When the arm 26 is in its normal'position on either side of the central line, this bolt 41 can be screwed inward, so as to-hold the arm 26 rigidly in position, the

unlocking movement being of course eiiected y essential features, and there by unscrewing the bolt, without, however, wholly'disengaging it from the arm 26.

' 'In order to protect the working parts from careless handling of the draw-bar, I rovide anoiitwardly-extended shield 45 in t e `form of a U-shaped band whose lianges 46 are secured to the end of the car ira-me. The draw-head 47 is mounted upon the outer end of said shield 45, which thus embraces the actuating devices in such a manner as to minimize the risk of the draw-bar striking or punching them in the act of coupling.

7 -It is` obvious that various modifications .may be made-in the details of construction of my 'invention without de artinv from its ore'I do not desireto limit myself to the precise construction y and arrangement herein set forth.

Having thus described my invention, I claim 1. The combination with the car-frame and the car-body arranged to rock thereon; of a pair of rocking arms pivotally secured to one another and to the frame and body; and, actuatin mechanism for said arms connected to one o them between its connection with the other arm and its connection with the car-frame, substantially as set forth,

It will also be noted that by 2. The combination with the car-frame and the car-body arranged to rock thereon;

of a pair of rocking arms pivotally secured to one another and to the frame and body; actuating mechanism for said arms connected to one of them between its connection with the other armand its connection with the car-frame; and, mechanism for locking one of said arms in a position corresponding with the normal position of the car-body, suystantiallyl as set forth.

3. The combination, with the car-frame and the car-body, adapted to rock thereon, of a pair of rocking arms pivotally secured to one another and to the frame and body; a screw locking-pin mounted in one 'of' said arms; and sockets for said pin, arranged on each side of the central axis in correspondence with the alternative positions of thc rocking arms, when the carbody is in its normal position, substantially as set forth.

4, The.. ,coinbination, with the carbody having a rolling under surface; of a truck frame provided with supporting wheels; shoulders on said truckfra-ine extending transversely with respect to the axes of said wheels, adapted to form bearing-surfaces for the rounded portion of the car-bod f when the latter is in its normal position, substantially as set forth.

5. r[`he combination, with the car-body having a rounded under surface; of a frame having lugs on its under side arranged in correspondence with subjacent bearing-points; and springs whereby the frame is normally retained in a position to clear said lugs from said bearing points, substantially as described.

6. The combination, withv the car-body and its actuating mechanism comprising a lever-arrn arranged to rock in avertical plane; of an outwardly-projecting shield einbracin said lever arm; and a draw-head mounted 4upon said shield, substantially as described.

7. Thevcoinbination with the car-frame and the car-bodyarranged to rock thereon; of a pair of arms arranged to rock in vertical planes; horizontally-disposed pivots securing said arms to one another and to the frame and body; and, actuating mechanism for said arms comprising a stationary cylinder and a piston arranged to reciprocate therein iii connection with one of said arms, substantially as set iorth.

In testimony whereof I have hereunto IOO IIC

signed my name, at Philadelphia, Pennsyl-` vania, this 30th day of October, 1903.
