AIL-JOINT CHAIR AND FASTENING.

Application filed June 6, 1907,

Specification of Letters Patent.

Patented Sept. 1, 1908.

Serial No. 377,563.

To all whom it may concern:

Be it known that l, llionssrn LACHANCE,

a citizen oi the United States, residing at St,

Johnsbury, in the county of Caledonia and State of Vermont, have invented certain new and useful Improvements in Rail-Joint Chairs and Festenings and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others ski led in the art to which it appertains to n ece and use the segne. I This invention relstes to improvements in rail 'oint chairs and fastening devices.

The object of the invention is to provides rail joint chair end means adapted to be epplied thereto to'securely fasten the ends of the sections.

A further object is to provide s. reil chair having a rail fest-chi mechanism which may he quicklfy and easily released to permit the removal e mil section without disturb i 9 the chairs which support the seine.

ith the foregoing and other objects in view which will appear as the neture of'the invention is better understood, the invention consists in certain novel features of construction, combination and arrangement of parts as "will. he hereinafter fully described end claimed. 1 i

In the eceompenying drewings, Figure l is s view of the meeting ends two rail sections showing the application of the invention; Fig. 2 is stop )lsn view of the same; Fig. 3 is a vertics cross sectional view 35 th ough the end of e reil section, the chair e d fastening piste; Fi 4- is a, plan view of the with the rel. ends and *i estening piste removed; end Fig. 5 is a detail perspective View of the fastening piste.

Referring more particularly to the draw-- ing's, i denotes the chair which consists of s los plots 2 on one edge of which is an inally formed inwardly projecting ilenge 3 s adopted to he se 'cd with the u oi the toil s side of t 0 s oi the mils. *2 tin edge of the i enintegrellyrerdlyproi fish piste which is ed d to engage welbs of the rail sections, the upper edge of .ssh plots being adapted to engage the din side of the head of the rail thereby iornn'ng s, hrece for the some in the fish piste i is formed e series oi bolt holes 5 which are adapted to eline with similar holes 5 55 formed in the web of the rail sections, as

shown. in the piste 2 adjacent to the opposite edge of the same is formed a longitudinally'disposed dovetailed recess 7 along the outer edge of the central portion of which is formed an upwardly and inwardly projecting: flange 8 the inner edge of which is tapered longitudinally from one end to the other of the saline. In the base plate 2 adjacent to the inner edge of the recess 7 are formed spike holes 9, similar spike holes 10 being formed through the base plate 2 adjacent to its opposite edge.

in connection with the chair 1, I employ a rail fastening device comprising c fish plate 12 which is similar in construction to the fish plate 4- end is provided with a series of boltholes 13 which are adapted to elinc with. the bolt holes 5 and 6 in the plate 4 in the ends of the rail sections. Formed integrally with the lower edge of the fish plate 12 is a downwardly end outwardly projecting flange 14- which is adapted to be engaged with the upor side of the rail flange as shown. On the ewer side of the flange 14 adjacent to its outer edge is formed a longitudinally tapered tongue 15 which is adapted to he engaged with the recess 7 end with the tapered inner edge of the flange 8 whereby when said fish piste l2 endflenge 14 are engaged with the rail and the base of the chair 1, e wedging action will be imparted to the fish plate and flange to force the some into firm engage ment with the ends of the rail sections, thus securely fastening the seine. After the fastening device has been thus forced into position, the securing bolt 16 is passed through the holes 13 therein and through the elined holes 5 and 6 in the rail sections and fish plate 4, thus securely holding the parts in. position. In the flange 14 is formed spike holes 1? which when the fastening device is in place will aline with the s ike holes 9 in the base plate of the cheir so t at the spikes may be driven therethrough into the ties beneath the chairw By providing it rail chair or fastening device constructed as herein shown and described, the ends of the rail sections may be securely iestcned together end to the ties.

The arrangement of the fastening device as herein shown provides for the quick and easy removal thereof to permit the-removal and replacing of a rail section without disturbing the chairs.

By means of this device e broken rail insiy be temporarily repaired in cases of emer gency to permit e train tossfely pesszover the break. When used temporaril as above described the chair is secured to t e broken rail ends by sim ly drawing in the wedge shaped or tapere tongue 15, thus obviating the necessity of drilling the rail and applying lateral bolts.

Having thus described my invention, what I claim as new is z- A structure for the meeting ends of two rail sections comprising a fish plate for said ends having a flange to overlie the flanges on one side of the rails, a vertical portion serving to contact with the webs and under surfaces of the treads of the rails, said fish plate also having a base plate to contact with the under face of the base of the rail and having its opposite edges projecting beyond the edges of said base, one of said projecting edges having a dovetail recess formed therein provided with an overhanging tapering curved lip, a second lish plate applied to the webs and under faces of the treads on other sides of the rails, and having a flange to overlie the flanged portions on said other sides of the rails, said flange of the second fish plate being mounted insaid recess of the first men tioned plate and having its terminal curved so as to contact with the curvature of said recess, spike receiving openings provided in the flanges of the fish plates coincident with the edges ol the rail base, and spikes in said openings, openings in the fish plates and webs of the rails and bolts secured in said openings, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MODESTE LACITANCE.
