Specification ol' Letteri intent.

Applicltion flied April 2, 190B. Syria] No. 457,475.

To all whmn. it "my concern:

Be it known that I, ROBERT L. Srrns, a. citizen of the United States, residing at Knoxville, in the county of Knox and btnte of Tennessee, have invented it new and useful Improvement in Dump-Cars, of which the following is u specification, reference boin bad to the uooompanying drawing.

improvement relates particularly to dump curs constructed for the tilting of the body to either side and omnpris'i'ng mechanism for controlling such movement of the car by means of air or steam power applied through cylinders and pistons.

The 0b]ect of the improvement is to pro vide a. powerful and efficient and easily controlled mechanism for tiltii' g and righting the bodies of large dump cars used in construction work and for similar purposes.

In the aooomponying drawings, Figure 1 is a side elevation of a little more than one half of a car embodying my improvement, -the middle of the our bein indicated by the line 2--2, and the two ha You of the car at each side of said line bein identical; Fig. '2 is a section on tl1e1ine,2 of Fig. 1, loolo ing toward the right, the section 'oing around the right hand cylinder; Fi is a horizontal section on'tho line 3-4) 0 Fig.v 2, looking downward Fig. 4 is a similar soction on the line L4 of F 2, looking downward; Fig. 5 is a seetionfi elevation of one of the hinges upon which the car body turns; 6 is a. transverse upright section of snid hinge.

Referring to said drawings, A 1;.- one of E whiehlhe car is supported, a similar true being under the opposite end of the ear. Upon said trucks rest two horizontal parallel beams or sills, B, which constitute the chief members of the under-framinfi Said sills are horizontally opposite m near each other, and at opposite sides of and oqui-distant from the upright middle longitudinal plane of the car. Chairs, G extend across and root u on said sills an are secured thereto by [)0 ts, 1. Euch chair has two upward-directe ears, 2 which stand opposite each other in e middl n I upright. plane of the car. And each ear has mnperture, 3,011 an axial line which in hr nit]. and m Sli Plane.

D-1a the car bod o the bottom thereof above each ebn'ir, is secured a. hinge 'member,'E, which extends between the ears, 2,

e Iongitudi-.

and has on aperture, 4, axially in line with the apertures, 3. A pin or bolt, 5, extends through the apertures 3, of the ours, 2, ahd the a Jerture, 4, of tie hinge member, E. Any esirrd number of said chairs amlhin o members may be used to give the our ha y proper support. The uuiuplote our of the drawings has nine such chairs and hinge members. By means of said chairs and members and snid bolis, the our body is supported in such manner as to permit tiltin to either side or standing in the horizontu position.

To normally hold the. our body in the horizontal position, slay chains, U, are applied at. each side oE tho oar, each vhain being attached by its upper end to an angle plate, 7, on the ttom of the car body uonr the adjacent. outer edge of the latter and to a. clcvis, 8, which secured to the adjacent side of the truck b a bolt, 9. All of said ohnins comprise a 100k, 10, which permits the seg'iarating of the chains ut the side of the car bod which is to go up when said dy is to be titled.

Midway between the [no ends of the our, 11 lu uwer, 1*, is applied in lilo hoams or sills, B, said hanger comprising upright members, 11, the upporend of onebooting against, the inner face of one oi. said heaum and the upper end of the. other of said members beurin against the inner face of the other of Sllit beams, and each of said members having a. horizontal arm, 11!, resting upon the upper face of: the adjacent sill and secured thereto by an u might boll, 15L Neur their lower ends said upright. members uro 'oined by a trausvome member, 1.4.; and each upright nu-mbi'eulnis at its lower end an arm, 15,.

extending horizontally away from the middle longitudinal uprlfiht plane of the our.

, Al. ouch :-hh-. of sold hunger is applied an upright i-yliuder, (l, the lower end of ouoh cylinder rmliun upon the mljuront. arm, 15, of the yolnand the shit of ouoh cylinder being secured to Lho adjmzout hunger and sill b means of horizontal bolts, 11;, extendin t irou 'h flanges, i7, and said hanger and i i (.weo "igs. 2., 3, and 4), nud the lower flange of the ud'aoout sill being out away suflieioully to mu in room for the cylinder.

.t fluid su )ply pipe, 18, is tapped into the lower end 0 each cylinder and ends to any suitable source of steam, 'uir, or. other fluid supply, not shown, whereby such Iluid may be forced into said cylinder.

1' or am the car bod Upon the upper end of each cylinder is a removable head, 19, havin u central port or throat, 20. Within the cyinder is a. piston, 21, lmv ing upon its upper face a centrally located c'irculer and exteriorly screw-threaded upward extension 22, in the up or face of which is formed a half s hericn cavity, 23. A cylindrical tube, 24, as its lower end screw-thr aded around the piston extension, 22, and e. tends upward and slidubly through the port, 20. Said tube is lon enough to remain within said port when t he piston is at the bottom of the cylinder. Above each tube 24, a bracket block 25, is secured to the bottom of the car body. A iston rod, 26, is located within each tube an hinged by its u per end to the ,edjucent bracket, 25, and a: at its lower end a ball llttHl, 27, resting-in the half spherical cavity, 23. An npertured bearing b ock, 28, surrounds said lston rod and the upper portion of said all head and bears upon the piston extension 22. i

when the car body is in the horizontal ition, as shown in Figs. 1 and 2, the pisdiis in the two clylinders stand horizontally opposite each ot er and about midway between the two ends of the res ectivc cylinders and the chains at each sis bflxly are coupled to hold said body from The operation for tilting and subsegluently righting the car body is as follows: ssuming that the car body is to be tilted toward the right, the right hand side going down and the left hen side going up, the chains at the left hand side are uncoupled and air or steam, or other fluid, is forced into the left hand cylinder through the fluid pipe, 18 whereb I the piston in said cylinder is forced upwa the adjacent tube, 24, and the piston rod being forced up'ward by the piston, the piston rod-being made. to bear upward on the adjacent bracketblock, 25, to press the left hand-side of the car body u werd. During such 11 ward movement 0 these several parts at a left hand side of the car the correepondinglparta at the ri ht hand side of the car a ri ht hand si e of the car body, the bracket ock, 25, the. piston rod, the piston tube and the iston-move borne ndingly downward. $711 again ri hted, the

en the car is to ectionjust described is reversed y forcin steam air or other fluid into the right his through the adjacent fluid ipe, 18,

y has assumed the ori'zontel tion. Thenthe chains at the left hand side of the car are again connected. Dnrin such operation, the tained in its me] elinement y the engagement of the tubular upward extension of the piston with the upperportlon of the cylinder, and the piston rod makes its lower in said axis e of the car v joined to the car body.

Liston is mninengagement, with theJJiston at or near the bot y of the latter an the base of said extension. And durin said operation, the horizontal line on w ich the iston rod is hinged or coupled to the braclset block 25, does not cross the upri ht axial line of the piston and c linder. For said hinge line is line and also horizontally opositc the hinge line upon which the car- )ody tilts. Hence when the car body tilts, the upper hinge of the piston rod wil move in an arc to which the axial line of the pieton and cylinder is tangential, said are being between said axial line and the hinge of the car hotly,

In Fig- 2, and B indicate the u and lower limits of the u or piston hinge and the curves, A B, in 'cete said arcs. The n per end of each piston rod is curved toward the middle longitudinal uprilg plane of the car, in order that it may c the upper portion of. the piston guide or tension when the piston and the piston rod are at thcirlower limit. It Will be observed that this structure permits a main tained connection lwtween the piston and the car body and makes feasible the tilting of the car by a single movement of the piston, notwithstanding the fact that the u right space allowed for the placin of t e cy inders and their adjuncts is re atively very limited, as may be seen bynotl the distance between he lower edges 0 the truck wheels and the bottom of the car body in Fig. 2.

I claim as my invention:
