METALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. r759,669, dated May 10, 1904.

Application filed February 16,1904. Serial No. 193,323. (No model.)

To all whom t may concern.-

Be it known that we, SAMUEL H. OAUFMAN and JOI-1N BALDT, citizens ofthe United States, residing at Chester,` Delaware county, State of Pennsylvania, have invented a new and useful Improvement in Metallic Railway-Ties, of which the following is a specification.

Our invention relates to metallic railwayties. It provides a tie with a water-shedding surface, with a rib the depth of which is decreased at its middle point to provide a certain resilience to the tie, with a box or recess to hold a rail-seat of sound-deadening or electrically -insulating material, with proper strengthening means beneath said box, witha novel form of clip for the [langes adapted to rail-llangcs of different widths, with a novel engagement between the tie and the clip, and

y with novel means for securing such clip in position.

,lt further consists of novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents in plan view a portion of ametallic railway-tie embodying our invention. Fig. 2 is a vertical section through the line .fc m, Fig. 1. AFig. 3 is a similar vertical section showing a modilication. Fig. 11 is an end view of the form of the device shown in Fig. 1. Fig. 5 is a transverse section through the line .1/ y, Fig. 2, with all the detachable parts removed. Fig. 6, on a reduced scale, represents the entire device.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the top plate of a metallic railway-tie, which may well be of cast-steel or similar material. As shown, its faces 2 and 3 are slightly inclined, and an end portion l has a similar incline, so that the tie will shed water in all directions. Running longitudinally of the plate is a llange 5, the portion (i of which is reduced in depth from the bearing-points toward the center, as clearly shown in Fig. 6 of the drawings. At a distance apart corresponding to the gage of the railway are recesses or boxes 7, open at their upper sides and provided with horizontal flanges 8. Beneath the boxes 7 are transverse ribs 9. Projectingfrom each side of the boxes 7 are recesses 10, having an undercut portionV 11, as clearly shown in Figs. 2, 3, and 5 of the drawings. The boxes 7 are adapted to hold blocks 12, which may be ofwood, Vulcanized liber, or other sound-deadening or in sulating material. As shown, these project slightly above the flanges 8 and form a base on which is laid the flange 13 of the rail 14, the width of the block being substantially that of theflange. Adjacent each recess 1() on the upper side of the flange 8 is formed a plurality of transverse grooves 15, at the ends of which are preferably provided longitudinally disposed lugs 16. The clip 17, having a tongue 18 adapted to engage over the railllange 13, is provided at its lower side with corresponding eorrugations 19. rlhe clip 17 is longitudinally slotted at 2O to pass a bolt 21, lthe head 22 of which engages in the undercut portion 11 of the recess 10 inthe tie 1. A nut 23, engaging with the bolt 2l, serves to hold the clip 17 in position. It will be seen that the head 22 of the bolt extends forwardly and laterally and that its rear sid c is rounded to permit it to enter the recess 10 after the blocl 12 has been placed in position. y

The operation is as follows: The tie 1 having been properly laid and leveled, the blocks 12 are placed in the recesses 7 and the rail 111 laid. The bolt 21 is then passed down through the recess 1() and its head 22 engaged against the upper side of the undercut portion 11. The clip 17 is then put in place, with the tongue 18 engaging' with the flange of the rail, and forced inward toward the rail as far as possible and the nut 23 iirmly secured on the bolt 21 in any desired manner. It will be seen that the corrugations 19 of the clip 17 engage with the corrugations 15 of the llange 8 of the tie, so that the clip may be moved longitudinally of the tie to provide for a difference in the width of the rail-tracks or curves. It will also be seen that the clip 17 is l'rmly engaged between the longitudinal lugs 16 on the flange 8, so that any movement of the clip laterally of the tie is absolutely prevented.

1n Fig. 3 of the drawings l have shown a slightly modilied form of construction :in which the contacting surfaces of the flange 8 TOOy and the clip 17 are smooth, the upper surface of the clip being corrugated to engage with a similarly-corrugated washer 24C, interposed between the clip and the nut 23. It will be seen that, as before, provision is made for movement of the clip longitudinally of the tie and for preventing accidental displacement.

Itis evident that the block 12 may be used not merely as a preventive of excessive vibration and consequent noise, but also to insulate the rail electrically. In this case it will of course be necessary to provide insulation either between the iiange 13 of the rail and the clip or between the clip and the tie. As these methods are well known and form no part of our invention, we have not deemed it necessary to illustrate them.

B y cutting away the central portion of the iange 5, as shown in Fig. 6 of the drawings, the resiliency of the tie is very much increased without lessening its strength.

It is evident that various changes lmay be made by those skilled in the art which may come within the scope of our invention, and we do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent, is-

1. A metallic railway-tie comprising a top plate and suitable sti'ening means, said top jacent said block, in combination with means for securing the rail to the tie.

4C. A metallic railway-tie comprising a plate, longitudinally-disposed lugs on said plate and transverse corrugations intermediate said lugs, in combination with a rail-clip adapted to seat between said lugs and having on its lower face transverse corrugations adapted to engage with the corrugations on said plate and a bolt for securing such clip to said plate.

5. A metallic railway-tie comprising a plate, longitudinally-disposed lugs onv said plate and transverse corrugations intermediate said lugs, in combination with a rail-clip adapted to seat between said lugs and having on its lower face transverse corrugations adapted to engage with the corrugations on said plate, said clip having an elongated 'bolt-receiving aperture therethrough.

6. A metallic railway-tie comprising a plate provided with a recess adapted to retain an insulating-block and an undercut bolt-receiving recess communicating with said iirstnamed recess.

7. A metallic railway-tie comprising a plate having a plurality of transverse corrugations and longitudinally-disposed ribs at each end of said corrugations and an aperture adjacent said corrugations for receiving a clip-engaging bolt.

8. A metallic railway-tie comprising a plate provided with a recess adapted to retain an insulated block and an undercut bolt-receiving recess extending laterally Jfrom said firstnamed recess in combination with a bolt, the body of which is adapted to pass into said recess and which has a head laterally and for-- wardly extended from said body.
