RAIL-FASTENER.

To all whom t may concern Be it known that I, JOHN N. SOHWALEN, a citizen of the United States, residing at Hudson, in the county of St. Croix and State of Visconsin, have invented certain new and useful Improvements in Rail-Fasteners; and. I do declare the following to be a full, clean-and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in rail fasteners.

One object of the invention is to provide a rail fastener adapted for use in connection with metal or concrete ties yand comprising a chair, rail engaging members and removable means for locking the rail engaging members to the chair in position for securely fastening the rails thereto.

Another object is to` provide a rail fastener which `may `be quickly applied to the tie and rail and which will securely brace the rails and prevent the same from spreading. Y

With these and other objects in View, the invention consists of certain novel features of construction, and the combin ation and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure A1 is a plan view of a railway tie showing my improved fastening devices applied for fastening the rails thereto; Fig. 2 is a part side view and part longitudinal section of the tie and rail fastening devices; Fig. 3 is a perspective view of one of the rail supporting chairs of the tie and which form part of my improved rail fasteners; Fig. 4 is a detail perspective view of one of the rail clamping members of the fasteners; Fig. 5 isa similar view of one of the keys for locking the clamping members in operative engagement with the rails and chairs; Fig. 6 is a similar view `of the bolt for removably fastening the keys in place.

My improved rail fasteners comprise chairs 1. consisting of base or tie'engaging blocks 2 having on their upper surfaces transversely disposed flat seats 3 on the upper sides of which are upwardly projecting suitably spaced stop flanges 4 which, when the rails are in place on the seats engage the opposite edges of the base lianges of the rails and securely hold the latter against spreading. In the blocks 2 Specification of Letters Patent.

and seats 3 rof the chairs and intersecting the flanges 4 are vertically disposed passages 5 the lower ends of which communicate with a longitudinal recess 6 formed in the lower side of the blocks 9, of the chairs as shown. The passages 5 extend from the inner sides of the stop flanges 4 to the outer edges of the seats 3 Iand on the seats at the opposite sides of the passages 5 are formed pairs of upwardly projecting transversely disposed parallel lugs 7 which extend from the inner surfaces of the stop ianges 4 to the outer edges of the seats and have therein alined rectangular bolt holes 8 the purposel of which will be hereinafter described. The rails `are securely held in engagement with the seats 3 and between the stop flanges 4 by pairs of clamping members 9 each of which comprises a vertically disposed bar 10 having on its upper end an inwardly projecting rail engaging lug 11 which is adapted to engage or hook over the base flange of the rail and which has its lower surface inclined as at 12 to correspond with the inclined upper surface of the rail flange. On the lower. end of the bar 10 of the clamping devices is formed a right angular inwardly projecting chair engaging lug 13 which when the clamping members are in place is adapted to engage or hoo-k under the upper wall of the recess 6 in the lower portion of the chair.

In applying the clamping members 9 they are inserted in the passages 5 of the chairs until the flower ends thereof come into engagement with the recesses 6 whereupon the clamping `members are moved toward each other in the passages 5, thus bringing the lugs 11 on `the upper ends thereof into engagement with the base flanges of the rail and the lugs 13 on the `lower ends thereof into engagement with the upper wall ofthe rehcess 6 .as clearly shown in Fig. 2 of thc drawing. When the clamping members have thus `been applied `to the rails and chairs, said members are securely held in this position by keys 14 each of which comprises a rectangular body portion, the width of which corresponds to the width of the spaces between the outer sides of the clamp ing members and the :outer walls of the passages `5 so that when saidl keys are dropped into said passages between the clamping members and the outer walls of the passages the clamping members will be held in opera- 11G tive positions and .cannot become disengaged from the rails until the keys 14 are removed.

On the upper ends of the keys 14 are outwardly projecting or offset heads 15 whlch when the keys are in place engage and rest on the upper surface of the chairs and thereby support the keys in the passages 5. On the opposite sides of the heads 15 are formed laterally extending lugs 16 which are spaced a short distance above the upper surface of the chairs to permit the insertion of a bar or other instrument whereby the keys may be forcibly removed from the passages 5 in the event that said keys become stuck from any cause. vIn the inner edges of the keys near the upper ends thereof are rectangular notches 17 which when the keys are in place aline with the bolt holes 8 in the lugs 7 and with said alined bolt holes and notches are engaged rectangular key fastening bolts 18 having on one end heads 19 and in their opposite ends apertures 20 with which are engaged eotter pins 21 or other suitable fastening devices whereby the bolts are prevented froin becoming casually disengaged from the lugs 7 and keys 1li. IVhen the keys 14 are fastened by the bolts 18 in the manner described it will be seen that it is impossible for the keys to jar out of or to be actually disengaged from the passages 5 in the seats of the tie. The keys 14 are preferably of such length that when engaged with the passages 5 in the seats the lower ends of the keys will engage apertures 2Q formed in the bottom of the ties, said keys thereby assisting in rigidly fastening the chairs in the ties.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

1. A rail fastener comprising a chair having therein vertically disposed passages land in its lower side a transverse recess connecting said passages, rail clamping members having on their upper ends rail engaging lugs and on their lower ends chair engaging` lugs, said members being adapted to be inserted in the vertical passages of the chairs to bring the lugs on the upper ends thereof into engagement with the base flanges on the rails and the lugs on the lower ends thereof into engagement with the upper wall of the recess in the lower portion of the chair, keys also adapted to be engaged with said vertical recesses in the chair and to firmly hold said clamping members in operative positions, and means to fasten said keys in operative position in the chairs.

2. A rail fastener comprising a chair having therein vertical passages and a transverse recessconnecting the lower ends of said passages, a rail receiving seat on the upper surface of said chairs, stop flanges formed on said seats and adapted to engage the opposite edges of the base flanges of the rails, rail clamping members adapted to be inserted in said passages and having` on their upper ends rail engaging lugs and on their lower ends fastening lugs adapted to be engaged with the upper wall of the recess in said chairs, keys also adapted to be engaged with said passages whereby said clamping members are held in operative position, and means to fasten said keys to the chair.

3. A rail fastener comprising a chair having therein vertical passages, and a transverse recess connecting the lower ends of said passages, a seat formed on the upper surface of said chair, parallel stop anges formed on said seat and'adapted to engage the opposite edges of the rail flanges, apertured lugs formed on said seats and projecting upwardly at theopposite sides of said passages, rail clamping members adapted to be engaged with said passages and having on their upper ends lugs adapted to be engaged with the base flanges on the rail and on their lower ends lugs adapted to engage the upper wall of the transverse recess in said chairs whereby the rails are securely fastened on said seats, keys also adapted to be engaged with said passages whereby said clamping members are held in operative osition and having in their upper ends notches adapted to register with the apertures in the lugs on said seats, key fastening boltsremovably engaged with said registering notches, and recesses whereby the keys are held in position, means to prevent the casual disengagement of said bolts from said lugs and keys, offset heads formed on the upper ends of said keys and adapted to engage the upper sides of the chairs and lugs formed on the heads of the keys whereby an instrument may be applied to forcibly extract the keys from said passages.

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