Specification of Letters Patent.

Patented (Jet. 24, 1905.

Application filed April 3, 1905. Serial No. 258,514.

To a, 1071,0111 it Ina/y concern:

Be it known that 1, JOHN G. ARCHIBALD, a citizen of the United States, residing at Bayside, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Cement Ties and Rail-Fastenings Therefor; and I do hereby declare the :lollowing to be a full, clear, 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 cement ties and rail-fastenings therefor; and the objects of the improvement are to provide simple means for holding the flange of a railroad-rail down upon the tie-plate and also to provide, in combination with the tie-plate, means for holding the tie-plate to the cement tie and for preserving the gage of the rail if the tie becomes cracked or broken.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing part of a tie, tie-plate, and rail, the spike-locking device being shown in dotted lines in position ready to insert in the tie-plate. Fig. 2 is a similar perspective showing the locking device in place and showing the means for connecting together the means by which the tieplates are held down to the tie. Fig. 3 is a perspective of the locking device; and Fig. 4 is a perspective broken away in part, showing the wooden block by which the locking device is kept in place and indicating the corresponding locations of the tie-plate and locking device.

As is clearly shown in the drawings, the device consists in molding or otherwise embedding in the upper surface of the tie 1 a steel tie-plate 2, provided with a slot 3, having a notched opening 3 at one end, making the slot IF-shaped. Beneath the slot and underneath the tie-plate is provided a recess 1 in the top of the cement tie to admit of adjusting the locking device. This device consists in the steel hook, (illustrated in Fig. 3,) consisting in a Hat beveled upper part 4: to engage the flange of the rail, as indicated in Fig. 2, a vertical shank or stem 4, and a T-head 4, the parts 4 and et" being rectangular in cross-section.

To insert the locking device, it is turned to the position shown by dotted lines in Fig. l, and the T-head 4:,which is of the same longitudinal length as the slot, is inserted therein. The locking device is then moved forward until its shank 4c enters the notched end 3 of the slot, when the locking device is given a quarter-turn to bring it into the position shown in Fig. 3. It is then pushed back to the small end of the slot 3, as shown in Fig. 2, the T-head 4 then being crosswise the slot 3 and engaging the under side of the tie-plate 2, and the hook .L is locked to the rail-flange. To prevent lateral movement of the locking device in the slot, 1 insert in the slot a wooden plug 7 (illustrated in Fig. l) to fill the open part of the slot.

To hold the tie-plate 2 in the tie 1, I provide suitable bolts 5, and to further secure the bolts and also to assist in preserving the gage I connect the bolts 5 of one rail with corresponding bolts of the other rail (not illustrated in the drawings) by wires 6, attached to the bolts in any suitable manner, as by running them through holes 5 drilled through the bolt 5. These wires are embedded in the cement when the tie is molded.

By the means above described I have produced a locking device which is cheap in construction and not liable to get out of order.

What I claim as my invention, and desire to secure by Letters Patent. is as follows:

1. The combination of a cement tie, a tieplate embedded in the surface thereof; said tie-plate being formed with a T-slot; a recess in the surface of the tie beneath said "IF-slot and a locking device comprising a liatted hook having a vertical stem and a IF-head, the T- head being adapted to enter the IF-slot of the tie-plate and adapted on being turned to engage the under side of the tie-plate and the top of the rail flange, substantially as described.

2. The combination of a cement tie, a tieplate embedded in the surface thereof; said tie-plate being formed with a T-slot; a recess in the surface of the tie beneath said T-slot; and a locking device comprising a i'latted hook having a vertical stem and a T-head, said T- head being adapted to enter the "IF-slot of the tie-plate and adapted on being turned to engage the under side of the tie-plate and the top of the rail-flange; together with a plug to fill the unclosed part of said T-slot, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN G. ARCHIBALD.
