HENRY F. COX, OF ALTOONA, PENNSYLVANIA.
RAIL-CHAIR.
SPECIFICATION forming part of Letters Patent No. 398,381, dated February 26, 1889. Application filed December 8, 1888. Serial No. 292,993. (No model.)
To all whom it may concern:
Be it known that I, HENRY F. COX, of Altoona, county of Blair-,State of Pennsylvania, have invented a new and useful Improved Rail-Chair, of which the following is a true and exact description, reference being had to l the accompanying drawings, which form a 1 part of this specification.
My invention relates to the ('0 istruetion if what are known as chairs for railway-rails, i and my object is to providearail-chair which can at the same timebe firmly secured to the T rail and upon the ties without requiring any part of the tiesnrface to be cut away.
The exact nature and scope of my invention can be best understood after reference to the drawings, which show rail-chairs having my improved features, and in which Figure 1 is a plan View of my preferred construction of chair secured on a rail. Fig. 2 is an end View on the line 9:0; of Fig.1, and Fig. 3 an end View of a somewhat modified form of my chair".
A is the rail; a a, the flanges of its base; B, the rail-chair, which I preferably form of malleable casting, as shown in Figs. 1 and 2. This chair is formed with aplain face for the rail to rest on, and its under sideis also plain in the sense of having no projecting parts to prevent its resting on a plain-faced tie. I prefer to give the bottom of the chair a wedge shape, as shown in Fig. 2, so as to tilt the rail A slightly to the inside of the track, and in that case it is well to core the bottom of the chair out, as is shown at b, so as to save metal.
0 c are plain proj ectingflanges of the chairbase adapted to extend out from it at two corners diagonal to each other, as shown.
D D are spike-holes formed in the flanges c c, and the chair is secured to the tie by spikes passing through these holes.
E is an inwardly-bent lug formed at the corner of the chair opposite to the plain flange 0, so that one of the bottom flanges of the railbase will rest against and beneath it, as shown in Fig. 2.
e e 2 indicate strengthening ribs in the malleable-casting construction.
F is a lug formed opposite to the plain flange c, and thereforeat the corner diagonal to the lug E, the said lug havingsubstam tially the form shown-that is, extending from the base of the chair first outward and upward, as atf, and then upward, and preferably somewhat inward, as at f. In the part f of lug F a bolt-hole, f formed, and the inclination of the lug should be such as to permit a bolt-head, I, to lie beneath the flange without coming in contact with the surface of the tie or requiring it to be cut away.
G is a clamping-piece, formed, as shown, so that one edge will rest against the inside of the partf' of lug F, and its other and lower edge preferal'ily fori'ned with a crotch, against the flange a of the rail-base. Abolthole, g, is formed in this clampingpieee, so as to be substantially in line with the bolthole f, and preferably I form a lug, 9, so as to extend down below the rail-base, a perforation, H, being made in the chair to admit this lug, as shown in Fig. 2.
I is a bolt; I, a bolt-head; J, a nut, and K a washer or nut-lock.
The construction shown in Fig. 3 is one adapted for the use of plate iron or steel in the formation of my chair. It is substantially the same in all its features as the chair shown in Figs. 1 and 2, and needs no further description. lug g and its corresponding perforation, H.
My chair is applied to the rail. very easily, either before or after it is secured in part to the ties. The clamping-piece being removed, the chair is easily passed beneath the base of the rail, and before the chair is placed upon the tie the bolt I is inserted with its head I beneath the part f of lug F. When the chair is in the proper position on the rail, the clamping-piece G should be adjusted on the bolt I with its upper edge against the part f of lug F, as shown, and its lower edge against the flange a of the rail-base. The lug g, extending into the perforation H, forms a stop apart from the bolt to keep the rail in approximately correct position. The clamp, being adjusted in approximately correct position and alignment with the rail, is spiked to the tie, and
In this figure I have omitted the the nut J is then screwed down on bolt I and is thus caused to press againstthe edge of the" rail, forcing it hard against the lug E and making the structural solidity of the rail and ehair substantially perfect. It is of course important that the chairs should be adjusted and aligned with care before they are spiked to the rails, so that the function oi. the elamplug-piece and bolt will be to clamp and hold the rail in position ratherthan to move it into position.
The leading novel Feature of my invention lies in the eon'lbination ot the peenliarlyformed lug l with the (:lampingpieee and bolt and with the chair, as deseribeifl.
Having now described my invention, what I claim as new, and, desire to seeure by Letters Patent, is"
.l. A rail-chair having an upward and inwardly-extendin glu at one corner, an n pward and outwardly-extending lug with turned-up edge at the corner diagonal to the first, and 1 plain outwardl x extending flanges piereed with spike-holes at the remaining two corners, in combination with a bolt passing through the outwardly-extendin lug with its head he neath said lug, a clamping-piece adapted to rest against the turned-up end of the outwardly-extending lug and the edge of the base of a rail resting in the chair, said clampingpieee being perforated to permit the bolt to pass through it, and a nut screwing on said bolt, all substantially as and for the purpose specified.
