DANIEL H. SNYDER, 0F SNYDERVILLE, OHIO.

RAILROAD-CROSSTIE.

Application filed September 10,-1919.

To @Z6 whom it may concern:

Be it known that I, DANIEL H. SNYDER, a citizen of the United States, residing at Snyderville, in the countyl of Clark and State of Ohio, have invented certain new and useful Improvements in Railroad-Crossties, of which the following is a specification, reference being had therein to the accompanying drawing.

rlhis invention relates to railroad cross ties, and has for its particular object to provide a combination cross tie, part metal and part wood, which will have the cushioning qualities of wood ties and the durability and general wearing qualities of metal ties.

It is an object of my invention to provide a tie of the two materials that will be of simple, substantial construction, requiring only a minimum of wood to provide for the wood cushioning effect, and which will be standardized with respect to the bolts and nuts which are used to secure the several parts together. l It is a further object of my invention to provide the tie with suitable rail clamps of improved construction which act to brace the steel rails laid upon the ties both laterally and longitudinally and also to prevent rising or torsional movement of the rails relative to the ties.

It is also a feature of the invention to provide the metal portion of the tie, en portions thereof which contact with the soil or other material of which the road bed is constructy ed, with lugs or cleats, preferably made iii- Vtegrally with the metal portion of the tie,

and acting to anchor the tie in the material of the road bed to prevent movement of the tie relative to the steel rails or the road bed itself. v Y

In the accompanying drawings,

Figure l is a plan view of my improved tie with the steel rails secured thereto;

Fig. 2 is a side elevation of the construction `shown in Fig. l;

Fig. 3 is an end view of the same;

Fig. L is'a bottom plan view of the metal portion of the tie; and

Fig. 5 is a detail of one of the rail clamps.

As here shown the metal portion of the tie consists of a channel l preferably of wrought iron or steel. Fitted into each end of the channel isa short section of wood, being in the form of a rectangular-'shaped wood block, having its upper surface substantially Hush with the upper edges of Specification of Letters Patent.

the channel, its outer end flush with the end of the channel, and its inner end extending substantially beyond the plane of the steel rail. The wood blocks may be secured in the channels in any suitable manner, as here shown, by lag screws 5.

The ties are laid in the road bed in the usual manner of embedding a portion of the tie in the road bed, the material of which the road bed is usually constructed, such as gravel, crushed stone, slag, cinders, etc., being tamped about the tie to level the tracks laid upon the ties and, as far as possible, to prevent or minimize movement of the ties relative to the road bed.

To further minimize movement of the ties relative to the road bed my improved tie is provided on the under side thereof with downwardly projecting cleats or lugs 6 which, as here shown, are formed integrally with the metal channels by punching V- shaped holes 7 through the bottom of the channel, the metal being cut free on two sides of the aperture and remaining intact on the other side, thus forming the triangular-shaped cleat 6 which projects downwardly a considerable distance substantially at right angles to the plane of the tie and,

serves therefore to more securely anchor the tie in the road bed. To make the cleats more effective they are preferably staggered and arranged alternately in planes substantially at right angles to each other.

The apertures 7 serve the further usefuli purpose of drain outlets for the metal channel, thus preventing or minimizing any accumulation of water in the channel and tending, therefore, to prevent rotting of the wood blocks 2.

When the ties have been thus arranged in the road bed the steel rails 3 are laid thereon and are secured to the ties by means of opposite clamps 4 4, secured to the metal portion of the tie by bolts 8, the clamps having jaws 4a by means of which they are adjusted to the rail flange 3, the end of the jaw being in the form of a nose lb which abuts against the web 3b of the rail, the opposite clamps thus acting one against the other to prevent lateral movement of the rail.

Inwardly adjacent each set of clamps, directly beneath the rail and extending beyond -the rail flange to clear the opposite edges thereof, are depressions 9, formed in the opposite sides of the metal channels, which serve as clearance spaces for the rail vai flange, thereby permitting the steel rails to rest wholly upon the wood blocks 2, the slight ilexibility of the woodactingto give to the rail inountings the resilient or-cushioning effect essential to good track construction. To this end also the clamp jaws are made `to contact `with the -upper portions ot the rail langes onlyfthere being ample clearance space provided in the clamp to avoid ,Contact with v`the mail flange :on .the under side thereof.

#it will be noted that the jaws-ot the :rail clamps conform vto the langle ot the rail liange .and that a relativ-ely wide holding surtace is thus provided ywhich acts effectually `:to prevent any rtwisting for .torsional movement of the rails, as well as vacting together with the 'portion olf the jaw 4b to prevent longitudinal and lateral movement of theirails relativeit'o the ties.

is here shown, the bolt heads-and :nuts employedin theassembling of my improved ties and securing the steel rails -thcreto are all of uniiorm standard size so :that one wrenchfor tracl'tool will .iit any bolt head or nut, this V*provision being made in ithe interest of standardized construction.

Vilhile my invention is -simple in constructionthe novel features thercoi are trelan tively'ota great importance. :The construction isicheap butsubstantial, and results in trac-lr vcon-struction which in lall respects is dependable, being tree from certain :com niondeiiects which it isidesirable @to overcome.

-Vliile allzthe goed qualities of wood are ypreserved sin effect in my improved lt only :the minimum ot wood required which, in 'viewof the increasing scarcity or wood suitable forties, is of'firstimportance. Furthermore the `wood blocks as used tliewties are protected largely from deterios rationfiirtheinetal channels which-nre properly drained through 'the apertures T 'to` minimize ithe accumulation of moisturev therein, Ithus acting as a 'further protection to the rwoed. Also, as will be Inoted, no spikes are used to secure 'the rails to the lwood so fthat all vexposed surfaces of the kwood are lrept intact and are Anot subjecttlierefore tothe destruction common to wood ties into which railspilres are=driven- As in 7the case ol my earlier invention relatii'ig to improved railroad ities, which forms the subject matter ot vPatent ifo. 1,233,413, issued July 17, 1917, Vthe wood block vfeature 'ot the present invention provides -i'or interchangeahility of the faces of the block relative tothe steel'rails rand also longitudinal V.adjusrmei'it relative thereto. Thusbyremoving the lag screwswhich se? cure `the blocks to the metal channels the blocks may be removed land reversedand shifted longitudinally in either Adirection without disturbing the metal ftie. By ythis isecisai the blocks relative to the rails from time to timeasdepressions are formed therein from the wear of the rails.

Having thus fully described my invention, what l claim as new and desire `to se- -cure by Letters .-atent, is
