Application filed .T anuary 15, 1913. Serial-No. 742.299.

To all whom it may concern Be it known that we, WILLIAM R. FUNK and CHARLEY .F. FUNK, citizens of the United States, residing at Archer City, in the' county of Archer, State of Texas,'have invented a new and useful Roller for Railway-Track Jacks, of which the following 1s a` specification.

The present invention relates to railway track jacks, and aims to provide a roller for the foot of the jack, which shall notencumber the jack, but which shall permit the jack to be readily moved on the rails of thetrack from one place to another.

The jacks which are at present employed in railroad work, such as for raising the rails, and the like, are quite heavy and cumbersome to handle, and in conveying such jacks from one place or locality to another, it has been the custom to slide one edge of the foot on the tread of the rails. This method, which is prevalent, is objectionable for several reasons, among them being the fact that this operation is both tedious and laborious, and causes considerable wearto the foot of the jack, as well as wearing the rail tread.

In many cases, it has been necessary for two or more men to carry or move a jack from one locality 'to another, and although there are devices on the market, for moving jacks fromoneplace to another along the track, no simple and practical means has been provided, which has come into any appreciable or extensive use.

It has therefore been the object of the present invention to so journal a roller to the foot of the jack, that the foot of the jack will not be encumbered, and to permit the roller to engage the rails, so that the jack may be readily rolled along the rails from one place to another with ease and despatch. This roller has not only been provided so as to eliminate the tedious and laborious operation of sliding the foot of the jack along the rails, but has also been provided to eliminate wear.

With the foregoing general objects out-- lined, and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and '.claimed. it being understood that changes in the precise embodiment of invention herein disclosed can be made Within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the-accompanying drawing, wherein Figure l is a fragmental perspective of an ordinary railway jack, the upper portion thereof being broken away. Fig. QA is a fragmental plan view of the foot or base of the jack, parts being shown in section. Figs. 3 and 4 are sectional views on the lines 3-3 and 4-4 of Fig. 2. Fig. 5 is a fragmental view of the roller.

Referring specifically to the drawing, the numeral 6 designates an ordinary or prevailing type of jack employe'dfor use in lifting rails and the like, and which is provided with the foot or base 7. Ordinarily, in conveying the jack from one locality to 'the other, the jack is supported in a diagonal or inclined position with one edge of the foot 7 contact-ing with the rail, and the jack is moved along the rails, the edge of the foot sliding over the rail treads, which operation is both tedious and laborious, and causes considerable wear, not only to the foot, but also to the rails.

In carrying out the present invention the roller 8 has been journaled terminally to one edge of the foot, or to the edge which is usually slid on the rail, this being effected by cutting aportion of the said edge away, as indicated by the numeral 9. The roller 8 fits within the cut away portion 9 wit-h its ends abutting against the ends or shoulders 10 of the cut away portion, the outer sido of the roller being preferably flush with the edge of the foot. At each end, the cut away portion 9 is provided with a step or bearing 11 with which the corresponding end of the roller 8 contacts, the faces 12 of the steps 11 being concaved to receive the ends of the roller. Thus, the intermediate or main portion of the roller is free or out of contact with the foot, the ends only being journaled.

In order to effectively retain the roller in position, a pair of U-shaped clips 13 straddle the edge of the foot 7 and have their ends or arms secured to the foot by means of i the bolts, or other securing members 14, the

intermediate portions or bends of the clips embracing' the ends of the rollers, and slightly overlapping the edge of the foot beyond the ends of the roller. The uppermost arms of the clips are relatively short, whereas the lower arms extend from edge to edge,

the bolts 14 passing throu h the lower arms adjacent the edges 'of the oot, and one pair of bolts passing through the u per arms of the clips. These bolts permit tiie cli s to be removed, so that a jack may be emp oyed in the usual manner. These clips 13 effectively retain the rollers in position, and assist in journaling the. ends of the rollers to the foot, but they do not encumber the foot, so as to preclude the ordinary or general use of the jack. On the other hand, the attachment is extremely simple, compact, substantial and inexpensive in construction and may be readily applied to jacks now in use with but little trouble and expense, and renders the jack readily transportable from one locality to another along t e roadway or track.

From .the foregoing, it will be evident that when the jack is to be transported from one place to another the foot may be readily thrown or lifted onto the rail, with the roller 8 engaging the tread, and by pushing or pulling the jack in the proper direction, the same may be readily moved along the rail as above intimated, the roller permits the jack to be readily, quickly and conveniently transported and eliminates wear which is incident to sliding the foot of the jack along the rail, as usual.

1. 'A jack having a foot, a portion of one edge of the foot being cut away, a roller fitting in the cut away portion, and U-shaped clips embracing the ends of the roller and having their ends secured to the upper and lower faces of the foot. 4

2. A jack having a foot, a portion of one edge of the foot being cut away and the cut away portion having a step at each end, a roller fitting in the cut away portion and having its ends bearin agalnst the ste s, and U-shaped clips stra dling the said edige of the said foot, and having their arms secured to the upper and lower faces of the foot, the bends of the clips embracing the ends of the roller and overlapping the said edge of the foot beyond the ends ofthe roller.

3. A jack having a foot, a portion of one edge of the foot being cut away a roller fitting in the cut away portion, thecut away portion having a bearing at each end for the respective end of the roller, and clips secured to the foot and embracing the ends of the roller.

In testimony that we claim the foregoing as our own, we have hereto aiiiXed our signatures in the presence of two witnesses.
