This invention relates to portable devices '61-. tools and has for its principal object to provide a portable press for use in assembling or disassembling draft gears, particularly friction draft gearsv v Other objects and advantages will appear in the following more detailed description of the invention.

In the accompanyingdrawings, Figure I is a plan view of a portable press embodying my invention; Fig. 2 is a side elevational view of the same; Fig. 3 is a side elevational view of the press in its vertical position; and Fig. 4 is a part plan view of a modification of the invention.

As shown in the accompanying drawings, my portable draft gear press may comprise a single integral frame member made in the form of a yoke having transversely spaced side pieces 1, longitudinally spaced

end pieces

2 and 3 and cross pieceset and 5 spaced from each other and from the end pieces2 and 3.

Intermediate the side pieces 1, the cross pieces areofiset outwardly, the offset portions supporting a plate 6 which is preferably perforated so that dirt will not collect on the plate. a V i The end piece 2 is made deep so as to provide a wide substantial base forthe presswhen said press is placed in a vertical position as shown in Fig. 3 of the drawings.

Depending downwardly from the end piece 2 and the cross piece 4 are transversely spaced vertical lugs 7 in which an axle 8 is mounted,

the ends of said axle having wheels 9 rotatably mounted thereon through the medium of which the press may be transportedfrom one place to another. a p v At the rear end of the framethere is a pressure device such as a screw-jack 10 having its housing 11 secured to the end piece 3 of the frame by a bolt 12 and nuts 13. This jack may be of the usual screw'type having its screw-threaded pressure member 14 disposed longitudinally of the frame and itsop r ENN'sYLvANrAQ 'AssIGNoit To mi;

If it should be desired to transport the draft gear or draft gear parts to another place, instead of removing them from the press when said press is in its vertical position, the press may be tilted so that the wheels are again in engagement with the ground and floor and the end piece 2 is out of engagement therewith, when a workman may, through the medium of the handle 16 e he P e s an it wh s t the desired location. V

While I have described the press as being in a vertical position to compress the draft gear, which is the preferred position, it will be understood that it may be used in a horizontal or any other position. In using the press in any position other than a vertical position, the Wheels would probably have to be chocked.

In Fig. 4 of the drawings a modification of the invention is shown, in which the jack housing 22 is made an integral part of the frame' of the press.

Inthe foregoing description the frame of the press has been described as a single integral piece, but it is to be understood that it may be built of a number of pieces suitably secured together.

While two illustrative embodiments of the invention have been described in detail, it is not my intent-ion to limit its scope to these embodiments or otherwise than by the terms of the appended claims.

Having now described my invention, what I claim as new and desire to secure by Let ters Patent, is z v 1. In a portable press, the combination With a frame adapted to receive a draft gear, said frame having an end piece adapted to support the press "in a Verticalposition and forming a seat for one end of said gear, of means carried by said frame adapted to be operated into engagement with the other end of said gear to compress the gear, and Wheels upon which said press is transported when the press is moved from a vertical position.

2. In a portable press for compressing draft gears in assembling and disassembling 1 said gears, the combinationwith an integral frame adapted to receive a draft gear, said frame comprising side pieces and end pieces, one of said end pieces forming an abutment for one end of said draft gear, of means carried by the-other of aid end pieces Operative to engage the-other end of said draft gear to compress the gear.

3. In a portable press for compressing draft gears in assembling and disassembling said gears, the combination with an integral frame comprising side pieces and end pieces between wh ch a draft gear may be inserted,,0ne of said end pieces forming an abutment for one end of a draft gear positioned between said pieces and also a support for said press when the press is in a vertical position, of means carried by the other of said end pieces and operative to exert pressure on the other end of
