EDWARD B. ENTYVISLE, OF JOHNSTOVN, PENNSYLVANIA, ASSIGNOR TO THE JOHNSON STEEL STREET RAIL COMPANY, OF KENTUCKY.

RAIL-CHAIR F OR STREET-CAR RAILS.

SPECIFICATION forming part of Letters Patent No. 364,996, dated June 14, 1887.

Application filed January 6, 1887. Serial No. 223,574.

the rail, riveted to the sides of the chair,

thereby securing maximum strength of clips with minimum weight of chair.

Box-chairs have heretofore been made by stamping out of the same metal the side clips for the rails; but in such stamping the quality of the steel or iron is deteriorated, and in order to obtain the clips of necessary strength when thus stamped out the whole chairor a large part of it must be made unnecessarily heavy.

The invention will first be described in de tail,and then set forth specifically in the claim.

In the accompanying drawings, Figure 1 shows an end view of one of the chairs forming the subject of this invention, having a center-bearing girderrai], shown in cross-section, mounted thereon. Fig. 2 shows said chair in perspective, detached from the rail.

In said figures the several parts are indi cated by letters of reference, as set forth in the following description.

The letter A indicates the chair proper; I3

the side clips riveted to the sides of the chair by the rivets O.

The rail is indicated by the letter E.

The advantages of this mode of construction may be summed up as follows: But one rivet (No model.)

is needed to each clip B, as the bend of the clip over the top edge of the chair prevents the clip from turning on the rivet as a center. The rivets may, however, be made square instead of round, if preferred. To increase still more the strength of the clips, they may, if desired, be made of a ribbed or flanged section. By the use of these side clips also, it will be observed, the width of the chair (indicated by the dotted line marked D,Fig. 1) may be made no greater than the width of the flange or foot of the rail E, which is impossible with clips stamped out of the metal of the chair itself, thus effecting great economy of material in addition to the other saving of weight above noted, due to the chair being of thinner metal than the clips.

In the drawings the chair is shown of a usual grooved form between the clips; but such grooving may be omitted, if desired. The clips, too, are shown staggeredthat is, arranged diagonally opposite each otherfor ready adjustment to and clamping of the railfianges by turning the chair at right angles to the rail after entrance upon its flanges. This mere staggering of clips is not, however, new per 80.

Having thus fully described my said improved rail-chair,as of my invention I claim- As a new article of manufacture, a railroad rail-chair of the hollow or box form described, provided with two sidcclips,as B B,diagonally riveted one each to the sides of said ehair,substantially as and for the purposes set forth.
