SLEEPER TIE Filed March 21, 1 928 r4 IHV EH ++mnam C15 ..|5Y mt/4 W ATTORNEYS Patented June 24, 1930 HERMAN C. BUJACK, OFOHICAGO, ILLINOIS SLEEPER TIE Application filed March 21, 1928. Serial No. 263,360.

My invention relates to an improved sleeper tie to be employed in securing a sleeper to a concrete base or floor bed. 7

An object is to provide a simple inexpensive sleeper tie which is capable of being readily secured in place in the concrete bed and quickly secured to the sleeper to be held thereon.

Another object is to provide a sleeper tie of the character described which is of a unitary construction being formed of a single strip of metal and which is so-bui1t that a large number of such ties may be stored in a relatively small space and shaped when used to be inserted into the cured to the sleeper.

A meritorious feature lies in the provision of a tie of this character comprising a pair of generally U-shaped portions arranged in opposed relationship with their backs disposed in substantially the same plane and preferably formed integrally. The structure is of such a character that the portion which is inserted into embedded therein, parts of the concrete extending therethrough, and the portion which is secured to the sleeper is readily deformable to embrace the sleeper and is perforated to receive fastening means.

In conjunction with my improved type of sleeper tie I have developed an improved -method of securing these ties into the concrete base, which method is particularly adaptable for use in connection with a tie of the charr acter described and whereby a plurality of 'such ties may be readily disposed within the concrete base at one operation in the proper spaced relationship therein.

Other objects, advantages and meritorious features of my invention will more fully appear from the following description, appended claims and accompanying drawings, wherein Fig. l is a plan view of my improvement.

Fig. 6 is a cross-sectional view through'the' same bedshowing the same tie and being at right angles to the view of Fig. 5.- V

My improved sleeper tie is preferably formed'of a single piece of sheet metal of the. shape shown generally in Fig. 1, wherein the opposite ends of the strip are cut providing opposed incisions 12 extendinginwardly from each endtoward the middle but terminating short thereof. Perforations, 1d are prefer ably made through the end port-ions on opposite sides of the incisions 12 and sharpened lugs16 are struck out of themiddle portion of the strip. I 'When the strips are used the opposed end portions on one side of the strip are bent to provide spaced apart prongs 18 which form with the connecting intermediate portion a structure of a general U-shape. The remain ing portion of the strip is adapted to be bent as shown in dotted outline'in Fig. 2 to form a second U-shaped portion, offset laterally from the first portion, and arranged oppositely with respect thereto so that the two u-shaped portions are arranged generally back to back with their backs lyingin substantially the same plane and forming an integral structure. Q

WVhenthe tie is used, a suitable method of embedding the same in the concrete is to fasten at intervals along a suitable carrier strip 20, which may be formed of wood,'a plurality of these ties by pushing the sharpened lugs 16 into the wood strip so that it will support the ties.

The carrier strip with the ties attached is then pressed down upon the surface of a concrete bed such as 36 while the same is moist, forcing the prongs 18 into the concrete. The concrete is then allowed to harden and the carrier strip is withdrawn from the lug. The ties when in this shapeare formed as shown in solid line in Fig. 2, and the prongs 22 lie on the surface of the concrete. These prongs are bent upwardly as shown in dotted line in Fig. 2 so that the upwardly extending U portion will straddle a sleeper 24! as shown in Figs. 5 and 6 and may be secured thereto by nails 26 extending through the apertures 14. The concrete itself extends through the apertures 14 in the U prongs which are embedded therein.

In Figs. 5 and 6 I have shown wedge blocks 28 which are commonly used to adjust the level and height of the sleepers and a floor structure 30 as resting upon the sleepers, and I have also shown the upper ends 32 of the ties as bent outwardly which is necessary only where such ties are too long due to the employment of a sleeper of a depth less than that for which the tie is adapted.

This particular sleeper tie is made of deformable metal so that it readily adapts itself to sleepers of different size but yet possesses sufficient strength for the purpose in question.

\Vhat I claim is:

l. A sleeper tie formed of a single strip of sheet material incised along its longitudinal center from each end towards the middle but terminating short thereof to form divided arms and provide a central rectangular saddle portion, spaced apart pointed tangs struck upwardly from said saddle portion on a line with said incision, linearly spaced perforations in each of the said arms, one pair of opposed arms being bent downwardly toward each other to form with the said saddle portion a substantially U-shaped structure.

2. A sleeper tie as set forth in claim 1, wherein the other pair of opposed arms are bent toward each other in the opposite direction to form, with said central saddle portion a second substantially U-shaped structure laterally offset from the first and inverted with respect thereto.

Intestimony whereof, I, HERMAN G. BU- .IAOK, sign this specification.
