Specification 01' Letters Patent.

Patented Dec. 8, 1908.

Application filed March a, 1905. Serial No. 252,095.

To all whom it may concern:

Be it known that I, ALBERT B. HERRICK, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Cars for Bonding Rails, of which the following is, a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. My invention relates to car structures, and particularly to a car'structure adapted for use in connection with operations to be performed upon the rails of car-tracks, such as rail-bondlng, joint-testing, and the like, as described in my application for Letters Patent, Serial No. 237 ,353, filed December 17, 1904.

The object of this invention is to effect such operations in an efficient and economical manner, said invention consisting of means hereinafter fully described and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention'may be used.

In said annexed drawings:Figure 1 represents a vertical longitudinal central cross-section of that artof a car embodying my invention, t e air-compressor and reservoir being shown therein in elevation, and one of the air-cylinders cut by the plane of section being shown in vertical section. Fig. 2 represents a horizontal section of the car showing the bottom thereof in lan, the air-compressor being however omltted being taken upon the plane indicated by line transverse section taken upon the plane indicated by line 33, Fi 1. Figs. 4., 5, 6,

and 7, represent a deta' ed plan elevation ofsections of portions of the mechanism on an enlarged scale.

The car-body A embodied in the structure is provided with a single truck A which sup orts a car-frame, as shown in Fig. 1. Suc frame includes two sills a (1 upon which is laid the flooring a, the latter being formed with a central rectangular opening a,-

springs as will 1.. Fig. 3 represents a vertical forming an open space between the bolsters a a and the wheels a a of the truck. Braces a a support the ends of the sills, the truck forming the struts which complete trusses for the car, as will be readily understood. Having its ends resting upon the central art of the sills a a is an arch A referab y constructed .of channel steel. his arch is preferably made so as to form a support for the central part of the roof, a, as described in said above-mentioned application and forming support for other parts of the mechanism which, however, forms no part of this present invention.

Secured to the sides of the car by means of suitable brackets h, Figs. 1 and 3, are four air-cylinders h and cooperating pistons h? therefor. These cylinders are connected by means of suitable pi es 71. with a reservoir H, as shown, where y compressed air may be admitted above the pistons by means of a suitable cock 717. An air-compressor H is suitably connected with the reservoir for supplying the samewith the required com& pressed air. The pistons operate vertically and there is secured to the lower end of each piston a rod and depending carrier rod h to the lower ends of which latter is attached a horizontal platform J, the latter being normally located a short distance above the rails of the track. This platform is held in such normal position, that is, the position in which the pistons are located in the u per portions of the cylinders by means of helical springs b which are attached to yokes h secured to the upper ends of the rods h, as

the sides of the car by threaded rods a supported in brackets a", suitable nuts a, being provided for ad'u'sting the tension of the e readily understood. It willtherefore be seen that when the-compressed air is admitted above the pistons the platform will be actuated downwardly toward the track and when such pressure is withdrawn the springs will act to return it to its normal position, a suitable relief valve (not shown) being provided in each cylinder, as will be readily understood, .to permit of .the unobstructed upward movement of the pistons, Cut in the platform immediatel above the two rails respectively of the trac N are two openings j Fig. 2, which ermit the operator to have access to the r s from the shown. These springs are suspended from interlor or the car for the purpose of performing the desired operationsupon such rails. y

Upon the bottom of the platform are secured members for effecting frictional contact with the rails. These members consist in the strncture illustrated, of brake-shoes K for stopping the car and contact brushes K for making contact for the electrical recording device for indicating and recording the electrical condition of the rails, such as is shown and described in pending application, Serial No.-209,115,- filed May 21, 1904. The contact brushes are, as shown in Fig. 4, mounted so as to normally be in a plane below the brake-shoes, so that they may' be caused to engage the rails while the brakeshoes are out of contact therewith. Such arrangement permits the recording evice to be used without bringing the brakes into play.' By employing the automatic cut-out device, shown and described in the ending application, Serial No. 209,116, filed lflay 21, 1904, the-braking of the car, that is, the downward action of the latform may be controlled automatically by the recording instrument, that is, whenever the voltage at the rail-joint rises above a certain point the car may be automatically stopped. In such case the cock h" would be automatically controlled.

' Attached to the front and rear ends respectively of the platform J, by means of flexible leather connections 7", are two guardplates J J which project upwardly into the central opening in the floor, as shown in Fig. 1, the upper ends of such plates resting against the front and rear edges of such" opening. These edges are extended downwardly by means of transverse boards a a, which, to ether with the extremities of .the' flooring- 'orm a support against which the upper endsof said guard-plates rest durmg the upward and downward movement thereof. These plates are bent forwardly and backwardly respectively as shown,.. so that their normal position'will be maintained by gravity. Apertures 7' j are formed therem for receiving the wheels of. It will therefore be seen that the openingsv betweenthe platform and flooring are closed by these plates thus protectingthe operator, and in conjunction with the sides of the. car substantially' inclosiilg the entire operating space on all four sides.

. .The front and rear ends of the platform are connected directly with the wheel-truck frame by means of links 1 whose inner ends are pivoted to the platform as shown in Figs. 4 and 5., The outer ends of these links are connected to the lower ends of the hangers A A of the trucks by means of pins o a)? suitably secured thereto. These pins pass through elongated openings Z res ectively,

55 formed inthe outer ends of these inks, and.

. truc when the platform is in its normal position engage the inner ends of these 0 enlngs, as shown in Fig. 1, so that when in t is position the latforrn is loosely connected with the 1B. When however, the platform is lowered and the brake-shoes are resting upon the rails the pins engage the oppositeends of the openings so thatin this position the platform is fixed relatively to the truck, and the longitudinal strain due to the frictional contact between the brake-shoes and rail, when the car is in motion, is transmitted to the truck, thus entirely relieving the rods 71, from such strain. 7

It will therefore be seen from the above construction that the.workman may remain in the operating space formed by the platform, raise and lower the latter as desired and perform various operations upon the rails with convenience and safety.

Having described my invention in detail,

. that, which I particularly point'out and distinctly claim, is:
