ARTHUR J. MOXHAM, OF JOHNSTOYVN, PENNSYLVANIA.

RAiLROAD-RAIL CHAIR.

SPECIFICATION forming part of Letters Patent No. 357,849, dated February 15, 188']. Application filed September 16, 1866. Serial No.2l3,671. (No model .T 0 aZZ whom it may concern:

Be it known that I, ARTHUR J. MoxHAM, of Johnstown, in the county of Cambria and State ofPennsylvania, have invented a new and useful Railroad-Rail Chair, which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to make a railehair of convenient form, efficient, and durable, which shall be capable of manufacture by drop-forging.

The invention consists of a chair of the form and character hereinafter described, and specifically set forth inthe claim.

In the accompanying drawings, Figure 1 illustrates in end view one form of my improved chair, showing a side bearing girdenrail in cross-section mounted thereon. Fig. 2 illustrates in plan the parts shown in Fig. 1. Fig. 3 illustrates a modification of Fig. 1, such modification being hereinafter particularly described. Fig. .4 illustrates in plan the parts shown in Fig. 3. Fig. 5 illustrates a horizontal cross-section through Fig. 3, taken at the line A B. Fig. 6 illustrates a further modification of the chair in which the upper part of the outside support of the rail is made to entirely conform to the shape of one side of the rails contour. Fig. 7 illustrates in plan the parts shown in Fig. 6.

In said figures the several parts are indicated by letters and numbers, as hereinafter described.

In Fig. 1 the letters II indicate the chair proper, and the letter J indicates the outside support of the rail F. The foot or one side of the lower flange of said rail is clamped to the body of said chair by the clamp c, secured by a nut on the bolt D. The said support J terminates belowin aright-angled flange in the same horizontal plane with the lower flange or foot of the chair proper, so that when the rail-support J is riveted to said chair by the rivets 7 7 it aids the chair in sustaining the weight of the rail by becoming, in fact, acomponent part of the chair itself. The upper portion, 8, of the rail-support .I is preferably slightly inclined inward, and the extreme end 5 is made angular, so as to fit neatly to the under part of the head of the rail.

In the center portion of the rail-support J the lug 8 is stamped out of the metal and thrown over and downward, so as to fit over one side of the lower flange of rail F.

In the modification shown in Fig.' 3 the differences from Fig. 1 are that the lower flanges or'feet, 1 2, are stamped out from both sides of the chair proper, H, and that the railsup'port J is cut or dished in to fit the outside portion of the rail F, and this cut portion embraces and holds down the lower l'langeinstead of the cutoutlug 8. (Shown in Fig. I.) The clamp c and bolt I) (shown in Fig. l) are replaced in Fig. 3 by the bolt E, passing through the web of the rail F, by which means the chair can be made narrower, if desired.

In the further modification shown in Fig. 6 the upper partof the rail-support- J is entirely made to conform to the shape of the outside part of the rail F. The web and foot of said rail may be secured to its chair H H in the manner shown in the other figures, or otherwise, as may be desired.

In all cast-iron chairs great weight is a 11ecessity, and rightangled braces are .generally used to lighten such weight. Such braces, although made thin enough and non-obstructive to the street pavements, are objectionable, in that they prevent the regular and steady work of the pavers. Each exposed brace represents a new starting iioint for the pavement, which fact requires considerable selection of suitable blocks from among those furnished, and consequently delays the work of bringing the other end of the portion of the pavement under consideration into close contact with the next exposed brace; or, further, if such chairs are used in Macadam or gravel pavement the exposed braces become objection able when such pavement wears away from the outside of the track, as it frequently does.

It will be noticed that there are no exposed braces in the chairs herein described 5 that an outside support is given to prevent the rail from turning outward, but that the support is of such form and shape that while of ample strength to properly hold the rail in place it presents no exposed points to interfere with the paving or to become objectionable if the roadway becomes worn.

An important feature in thisinvention, also, is that the outside rail-support is made of one piece and the chair proper of another. In
