Specification of Letters Patent.

Patented Oct. 27', 1908.

Application filed April 14, 1908. Serial No. 426,935.

To all i/ rlmm 'it may concern:

Be it known that l, Anemia )L Bunn, a citizen, of the United States, and a resident of Topekz, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in tallie Railroad-'1`ies, of which the following' is a full, clear, and exact description.

The purpose of this invention is to improve the construction of the cross tie, for which a patent July 2, 1907, and numbered SMQ-l2.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specitication, in which similar characters of reference indicate corresponding` parts in all the views.

Figure l is a perspective view of a cross tie en'ibodyine' the present improvements; Fig. Q is a detached perspective View of an attachable wing that is a detail of the invention; Fig. 3 a longitudinal sectional viewof a portion of the cross tie body having a feature of improvement thereon, the section beinev taken on the line l-l in Fig. it; Fig. -1 is a plan view of the portion of the cross tie body shown in Fig. il; and Fig'. 5 is a transverse sectional view of the improved cross tie, substantially on the line .3-5 in Fig. l.

t3 indicates the body of the cross tie, preferably constructed of steel plate cut and bent into shape, and as shown in the drawings, two side walls t3 are spaced apart by a fiat bottom wallpt), and thus held in vertical parallel planes, and it may here be explained that this form of the tie body is not 'claimed as broadly new, the samebeing shown in said vLetters Patent No. 858,942,

Two rail -loearing stools are. furnished, which are of simitar'form, cach consisting otl a top plate 7, and two side walls 7, which are bent at right angles from the top plate, and are thus disposed in parallel planes.

'lhe space between the outer. sides of the side walls 7 of each stool is such that they may be inserted down into the open top of the tie body, and fit closely against the inner surface of its side walls tj, the true free side walls 7l1 being seated upon the bottom Wall (3" of the tie body.

The stools are disposed at such a distance 'as granted vto me, dated l l l l l l l l l l l l l l i i 1 l i l l l i apart as will conform to the gage or degree oi' separation between the track rails, and each stool is secured within the tie. body by rivets u, which are secured in transverse perforalions ol the lapped side walls 6'l and 7a. The top plates 7 of the stools have their upper surfaces substantially liush with the top edo-es of the side walls 6 of the tie bodyl o, .so that the track rails A, A, may be seated upon said top plates 7 and be thereon secured by clamps that may be of any approved construction.

The features of improvement that are most important in this invention, comprise novel means for holding the body (l stationary, and pre.\f'entine` a longitudinal creeping' movement, that is liable to occur in a road bed of clay or wet soil in which the tie body may slip.

One detail of the invention for effecting; the purpose mentioned, consists in the formation of preferably V-shaped lugs C' on the lower side of the bottom wall G of the tie body G. These lugs in any preferred number, are formed integrally with said bottom wall by cutting,` the material forming' each lug loose at the side edges, leaving a transverse connection c remain intact, as shown best in Fig. 3, and the luer is completed by bending the same down at a right angle,- thus projectingA it from the lower side of the bottom wall G".

Another important novel detail of construction is shown detached in Fig. 2,- and connected with the tie body in Fig. l, this consisting; of a wing' rl, formed of plate metal, bent into shape by return folding a` strip of metal together at its center of length, thus forming the body of the wing', and at. opposite points d', again bending the strip at right angles outwardly from thewing formingi [langes rll, at opposite sides of the lat-ter, and disposing said tlang'cs in the same plane. 'lhe wings (l are mounted upon the outer surfaces of the side walls ti", of the tie body, and thereto secured by rivets d on bolts passed through transverse perforations in the flanges l? and said sidel walls f. Preferably two of these projecting wings rl are secured on the tie body oppositely and at its longitudinal center; but it is to be linderstood that an increased number of said wings, disposed at any distance apart, may

' be secured on the side walls of the tie body.

It will be seen that the projecting' Wings (l form abutments which will hold the tie body Stationary, and that. the luge c on the bottom Wallet said tie body -will cooperate with the Wings, for eileoting such a purpose.

The employment of the improved features in connection With an open channeled body for a metallic cross tie, is especially advanta geous for holding Such ties that are located on sharp curvesy of a railroad, or on any other portion of the `road-bed that may incline more or less laterally. n fact, the use of the Wings and lugs on the tie body is advantageous at any point, and in any Soil on a railroad track Where cross ties are liable to creep endwise.

Having described my invention, I claim as new and desire to secure by Letters latent:-

l. A tie comprising a. channel shaped body, channel shaped rail stools, having their side Walls inserted between the side Walle of the tie body, and seating on the bottom wall of the tie body, said body having bent down projections on its bottom and lateral Wings on its sides, each of said Wings comprising a strip folded upon itself, and

lhaving its free ends bent laterally, and secured to the tie.

2. A tie Comprising a channel shaped body, channel shaped rail stools, havlng their side walls inserted between the side ARCHIE MARKLAND BAIRD.
