RAIL-CHAIR.

more especially where the flat-bottomed rail is use-d.

The objects of our invention are: 1st, to provide perfect safeguards against the upsetting of the rail; 2nd, to provide side supports of the rail; 3rd, to provide means which minimize the cutting of the rail inthe tie; 4th, to provide a rail-chair which can be easily removed and replaced; 5th, to provide safeguards against creeping; 6th, to provide a more efficient, simplified,and lowcost article; 7th, to provide safeguards against spreading of the gage of the track.

Other objects will appear from the hereinafter description.

The invention is a rail-chair having wedge shaped, double plates, one upon the other, of which the thin edges are in opposite directions, presenting when in place a. uniform thickness of metal under the rail, a flat surface against the tie, with the downward flange at. the edge of the tie, and pre-- senting a flat surface to the flat bottomed rail, a clamp space over the flange of the rail on both sides, and side supports to the web of the rail.

When spiked to the tie in its effectual po sition and adjustments, our improved railchair is fastened to the tie by a spike through a hole in each end of the chair through both plates, clamping the rail to the tie by a positive look by means of the cutaway space in the braces, pressing the braces againstthe sides of the rail, and holding the rail from creeping by means of the flange down the side of the. tie.

In the accompanying drawings made part of this specification, Figure 1 is a perspective View of the rail-chair spiked to the tie, a part length of which is shown, and clamping a piece of a rail, showing in the whole a complete rail-seat; Fig. 2 is a perspective view of the separate parts of the rail-chair; 1

Fig. 3 1s a transverse section of the railchair through the braces; Fig. 4 IS a mod]- Specification of Letters Patent.

-fication showing pairs of side braces, two on each side of the rail.

A designates the rail-chair as a whole.

B is a side brace integral with the top, wedge shaped leaf of the bottom of the rail-chair, so shaped on its under side as to have a cutaway part b, which fits over the flange of the rail for the whole width of the Web of the rail. I

B 1s a brace, preferably smaller, integral with the bottom wedge-shaped leaf C, havof the rail.

The slde braces B and B may be in pairs on each leaf, as shown in Fig. 4.

chair; C is the bottom leaf thereof; D is a wide tongue of the wedge shaped leaf C, and E is a slightly wider groove in the top leaf C, wherein the tongue D fits and slides. D is a narrower tongue of the top leaf in the modified form shown in Fig. 4. E is a narrower groove in the bottom leaf, adapted to receive the tongue D, in which it slides. F is a side flange on the leaf C, extending downward and adapted to fit against one side of the tie. G is a tie or wooden sleeper of a railroad road-bed.

H is a railroad rail.

and through the bottom leaf, C, registering when the leaves are in place at the rail-seat and the braces B and B- are snug against the sides of the rail.

K is a spike through the holes I into the tie G firmly holding the leaves C and C in their effective locking position, and fastening the rail-chair firmly to the tie.

in constructingrailroads involving our improved rail-chair, the ties and rails are first laidin position; but instead of spiking the rail to the tie by the ordinary driven railroad spike/or screw spike, the rail is slightly pried up from the tie and the top \\'e(lgeshaped leaf C inserted from the outside of the rail. between the rail and the tie, and the bottom leaf C inserted under the top leaf C from the inside of the rail, and the two driven together until the side braces B and B are snug against the web i of the rail. The holes I through both leaves flange when the brace is sung against theing a cutaway space 6 fitting over the flange C is the top wedge shaped leaf of the rail- I is a hole through both the top leaf C C and G, then register, and a spike is driventhrough each pair of holes intothe tie, whereupon the construction is complete. Then adjusting the plate, the flange F is placed snug against the side of the tie, and the flanges on other chairs are placed on the other side of the tie, so that the clamped rail cannot move lengthwise without dragging the tie, and thereby the creeping of the track is prevented, or lessened.

In derailing accidents, where rails are spiked directly to the ties, it is readily seen that when the trucks of a passing train are swaying from side to side, the flange of the wheels may lunge against the inside edge of the head of a rail, tending to upset the rail outward, and putting the stress .on the inside spikes in a direction to draw the spikes; and this is the weakest spot in roadbcd construction. By our improved railchair, we put this stress against the outside larger brace. Against this the rail cannot upset, unless the outside spike is sheared off, and we thus transfer the force in operation from a drawing stress on the inside spikes, to a shearing stress on the outside spikes, and the latter offers manyfold greater resistance to this stress than the former. I

We do not confine-ourselves to the details of construction, but have described our improvement in its best form, but by way of illustration, and not by way of limitation. For example, without showing all the varia t-ions, we may omit the .groove and tongue wherein the wedge-shaped leaves fit, and may make the bottom leaf as wide as the top leaf; and we may make the leaves flat instead of wedge shaped, and may make the side braces the full width of the top leaf or less, and may make the braces inpairson both leaves, or on either; or may employ onlyone brace on each leaf, for whether the plates are wedge shaped or not, or move together in tongue and groove, when the side braces are brought up snug against the web of the rail, and the two plates are spiked to the tie through the holes I, the braces are locked against the tie-and the strains are converted as hereinbefore described; and thus we accomplish all the foregoing objects.

'We may obtain the objects of our invention in some degree by omitting the holes I and spiking the plates at, the edge, the

same as a rail is now-spiked direct to the tie. a

By the use of our improvement, we reduce the shearing strain on the spikes and lag screws.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is i 1. In a rail-chair, two wedge-shaped bottom plates, overlapping when in place, and adapted to be inserted at the rail-seat, the thin edges first, each carrying a clamp adapted to hold the flange of the rail, spike holes in each leaf which will register when the plates are in place, and adapted to receive spikes'when in such position.

2-. In a rail-chair, two wedge-shapedbottom plates, overlapping when in place, and

adapted to be inserted at the rail-seat, the

thin edges first, each carrying a clamp adapted to hold the flange of the rail, one of which clamps is also a side brace.

3. In a rail-chair, two wedge shaped leaves, a side brace on each, holes for both leaves, each adapted to receive'a spike, and a side flange adapted to fit the side of the tie.

4. In a rail-chair, bottom plates having a wedge-shaped channel in one, and a wedgeshaped tongue in the other, adapted to be inserted at the rail-seat from opposite sides of the rail, each plate carrying a clamp adapted to hold the flange of the rail, one of which clamps is also a side brace.

In witness whereof, wehave hereunto set our hands and afiixed our seals, at Stamford, in the county of Fairfield, and State of Connecticut, this 9th day o f -April, 1912.
