RAILROAD-TIE.

Specification df LettersPatent. Patented Dec, 15 1914 Application filed April 4, 1914. Serial No. 829,417.

To all whom it may concern Be it known that I, PATRICK J. MADDEN,

a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Railroad- Iies, of which the following is a specification.

My invention relates to an improvement in railroad ties and particularly that class of railroad or trackage using electricity or for electrical signal devices and connections or electrical attachments operating in connection therewith, and it has for its object to construct such a railroad tie by utilizing parts of wooden ties already laid so as to economize in the use of wood for tie purposes and at the same time to give rigid and safe support for the rails.

Another purpose is economy in trackage and to prevent the complete loss of partly used ties from which may be cut perfect and sound parts. It is for the purpose of utilizing these parts in connection with such trackage that my device is used and so constructed as to form a combined tie and plate and while preventing the waste of timber at the same time permits the springy features of wood and the strength of a metal tie and tie plate so as to effectually prevent the spreading of the rails.

With these objects in view my invention consists of certain novel features of construction and arrangement of parts as will be hereinafter fully described and pointed out in the claim, reference being had to the accompanying drawings in which:

Figure 1 represents a side View of my device. Fig. 2 represents a plan view of my device. Fig. 3 represents a side view of a modified part of my device. Fig. 4 represents a view in cross section of a fragmentary part of my device.

means of the nut bolts, the up-turned ends 2. 2 of the plates B. B, are thus clamped together. In each opposite end of each of the plates B. B, I have the recess 5. 5 and at the base of the recess 5. 5, I have the up-turned lugs .6. 6, the lug 6 being of hook shaped formation and the lug 8 being of vertical formation which lugs contact with the base A of the rails 7. 7. Mounted in the plates B. B are the usual rail spikes 8. 8. 8, etc, passing through openings in the plates, 9. 9. 9, etc. Beneath the blocks A. A, I have extending under said blocks the plate D and supporting the lower sides of said blocks A. A. From each end of D extends the upturned lug 10. 10. Through plates D and B. B are passed the bolts 11. 11 on which are mounted the nuts 12. 12, there being mounted about said bolts the insulating bushing 13. 13.

In a modified form of my device I have one section of plate B overlappingthe other section of plate B as shown in Fig. 3 and between which overlapping parts I have the insulating strip E. Passing through said overlapping parts B. B and through the insulating strip E, I have the bolts 3. 3 surrounded by the insulating bushing 4. I. Mounted on the end of plate D, I have the clamp H. 14 by means of the nut bolts 15. 15 which clamps l4. 14: extend over the ends of blocks A. A. WVhether the ends of plates B. B overlap or whether the ends have the upturned lugs as shown in Fig. 2 yet when bolted together by means of the connecting bolts they form one continuous plate.

Having thus described my invention, what I claim as new and what I desire Letters Patent for is as follows:

In a railroad tie, alining supporting members of wood, a sectional perforated binder plate formed of two sections, the opposite ends of which being perforated and turned up, mounted thereon, forming a binding connection between the members; each outer end of said plate having a recess therein; projecting lugs projecting from the base of each of said recesses and beyond the upper surface of each plate; one lug projecting. vertically at right angles, the other in hook shaped formation and each adapted to engage the outer edge of the track rail; an under plate extending beneath and beyond the ends of said supporting members and having upturned ends; a clamp eXtending over said supporting members A and down upon the extended end ofsaid supupper and lower plates of. said supporting porting plate and eontaoting With thenuprmembers. 10 turned ends of the supporting plate; be- In testimony whereof I have afiixed my tween the ends of said sectional plate insignature in presence of two itnesses.
