DRAW-BAR CARRIER.

Specification of Letters Patent. Patefitled Sept. 14, 1909.

Applicationfiled January 26, 1907. Serial N6. 54 ,3 52

To all whom it may concern:

Be it known that I, Cnnunns H. TOMLIN- son, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Draw-Bar Carriers,

of which the following is a specification.

My invention relates to a movable hanger or draw-bar carrier and is primarily adapted to be used for yieldingly suspending drawbars and couplers having a radial and horizontal movement and consists, primarily, in a carrier which is adapted to be used to sup port them and comprises supporting means suspended from a movable frame to support a draw-bar.

One of the objects of my invention is to provide a draw-bar carrier that will permit the draw-bar and coupling of each car when coupled to remain. constantly on a plane with each other and in proper position notwithstanding the fact that one of the cars is not on the same grade or plane as the other.

A further object of my device is to provide means whereby the supporting means upon which the draw-bar rests will automatically adjust itself so as to keep the draw-bars and couplings on a plane with each other on any plane or grade necessary to run the cars on.

Further objects of my device are to pro vide means of permitting the usual lateral movement of the draw-bar in conjunction with a vertical movement. and to provide a support for the draw-bar and coupling that will yieldingiy suspend their weight under normal conditions by securing the supporting means to the car body under such a ten- 4 son that it will balance their combined weight and when any undue strain or pressure is'brought to bear upon the sleeve the movable hangers carrying thesupporting means will move downward or upward according to the strain or pressure they are subjected to on account of any ditierence of grade caused by the tilting of the ear or I attain these and other objects in the accomotherwise. by. the mechanism illustrated panying drawings in which- Figure l is a side elevation 01": my device; Fig, 2,is a front elevation of the carrier with one side in vertical section taken thr ugh the line m, m, of Fig. 1'. Fig. 3, is a horizontal section of the carrier taken through the line n, 7b,. of Fig. l. Fig i is a plan view of the draw-bar carrier and the supporting 'ers 10 are provided for upper extremities 11 turned means shown in Figs. 1, 2, and 8 in: their rela-tive positions attach'ed to a car the outline of which is shown by the dotted line. This view, also shows the radial movement of the couplers. Fig. 5, shows a section of track with one 9nd inclined downward illustrating a grade with sections of two cars coupled upon the grade showing the draw-bars and couplers supported by the carrieron a plane with each other and the supporting springs of the yol(e mechanism of the car on the grade compressedby the draw-bar which e1:- erts more than a normal pressure or strain against the yielding supporting means when both cars are not on a plane with each other. Fig. 6 is aside elevation of my device with one car inclined upward illustrating the grade with sections of two cars coupled upon the grade showing the draw-bars and coup: lers on an incline and. in alinement with each other. It alsoshows the draw-bar pivotally connected for lateral movement and also for vertical movement above and below its normal position.

In the construction of my device, I prefer to use a frame comprising a base 1 with two downwardly depending arms'2 and 3 spaced apart leaving an opening 4:.

Vertical flanges

5 and 6 are made integral wlth the arms spaced apartand project downwardly therefrom intersecting with the horizontal upper and

lower flanges

7 and 8 respectively, which project from said arms and in conjunction therewith form rectangular recesses orcasings to inclose and support the compression springs 9, the purpose of which will be described hereinafter. Hangeach casing with the at an angle with the body. portion and adapted to aline with suitable apertures formed in the horizontal flanges 7. The lower extremities .12 of the hangers have eyes formed thereon with apertures formed therein at right angles to the apertures formed in the lower extremities. An opening 13 is provided in the lower extremities and side walls of the

arms

2 and 3 to'permit the'lower extremity of the hangers tobe inserted therein leaving the enlarged lower-portion 1 1. of the hangers extending inwardly flush with inner faces of the arms 2 and 3 'retaining them in place and pre- 50 plane as the 'r ca'r bodyjunde'r normal of undue strain or pressure caused by the cars being on a grade or different plane when coupled. A- sleeve 15 is interposed be- ,tween the inner facesv of'the enlarged lower portions of the hangers and mounted on the pin l6which is held in place by the cotter pins 17 and 18. The hangers 10 and sleewe when connected together fprmfsubstan tially an inverted yoke which is adapted to move vertically as will be described.

The coil springs9 are inserted in the casangular ends 11 of the hangers 10 thereby yieldingly suspending the parts comprising the inverted yoke. Through-going bolts 19 pass downwardly through the'fiange 7, angular ends 11 ofithe hangers through the inner periphery of the coil springs and thence through the flanges 8 leaving the ends projectingbelow and are retained in method of connecting place by any wellknown fastening means. The coil compression springs 9 are made of such a'size or tension as will counter-balance the weight of the inverted yoke, the drawbar and coupler that they yieldingly support whereby the draw-bars and coupling are retained on a plane for coupling purposes under normal conditions as when the cars are upon the same grade.

Referring to Figs. 1 and 2, the upper portion or base 1 of the frame is provided with a tee slot 21 which is adapted to engage with a curved tee bar 23 (see Fig. ably supports the frame and carrier and permits radial or lateral movement of the draw-bars 20.. The draw-bars are pivoted for lateral and vertical movement upon the pin 24, the opening being enlarged and rounded on the edges toward the center to permit of vertical movement above and below the normal'position of the draw-bars.

See Fig. 6. This is an old and well-known vertically movable draw-bars to the car, and forms no part of my present invention. The draw-bars. 20

- are plvoted upon the pin 24 in the usual manner.-

The draw-bars and coupling devices are secured to the draft rigging ofg thejcars.by;

any well known means andiformndpart of my invention.

The operat on of -my 1draw-bar'carrier is egfac'es at the same conditions.

When one (or bothlof the ears v :areupon a difi'rent grade aslshown'in Fig' '5, I a strain or, pressln'e' is:

' involved.

v ,jibear" use 'sle'eve and.

standing the-fact that the cars are running upon different grades with-respect to each other. When the sleeve and hangers forming the inverted yoke are relieved from the strain or-pressure the sleeve automatically returns to its normal position.

I do not confine myself to the exact construction shown, as it is obvious to any one skilled in the art that many changes can be made without departing from the principle Having fully described my invention, what I claim and desire to secure by Letters Patent is: p
