QUARTERING DRIVE-WHEEL PRESS.

Application filed- October 28, 1915. Serial No.'58,457.

To all whom it may concern:

Be it known that I, MARTIN M. MORAN, a citizen of the United States of America, residing at Ogden, in the county of Weber and State of Utah, have invented certain new and useful Improvements in Quartering Drive-Wheel Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to means for quartering locomotive drive wheels or mechanically spacing the pins 90 degrees apart when pressing wheels on an axle.

The principal object of this invention is the production. of a simple and efficient clamp which is adapted to engage the crank pins upon a drive wheel and correctly space the same adesired distance apart. I

Another object of this invention is th production of a simple and efiicient clamp which may be adjusted according to the different strokes of an engine with which the drive wheel is adapted to cooperate.-

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

a projecting armB, which arm is provided lVlth it notch 4 forming a guide, which guide is wlder at its outer end than at its inner end, to compensate for wear and maintain no alinementwithin the notch 4. It should be understood that this notch 4 is formed so as to extend at an angle of 45 through the resistance post, as clearly illustrated in Fig. 2.

A supporting ram 5 is placed within the notch 4 and this supporting ram 5 carries a vertically extending dove-tail rib 6 which dove-tail rib 6 is provided with a socket 7 at its upper end, as clearly illustrated in re Fig.- 8. The socket 7 is adapted to receive a pin, which pin is adapted to be carried by the threaded socket 8 of the vertically extending portion 9 of the primary section 10 of the clamp or ram: The vertically extending portion 9 is provided upon the rear face thereof with a pair of spaced flanges 11, which flanges are beveled upon their inner faces, as indicated at 12, for sliding upon the beveled faces 13 of the dove-tail so rib 6. It should be understood that the primary portion 10 of the clamp may be primarily held upon the dove-tail rib 6 if it should be so desired, by passing the pin through the threaded aperture 8 and into the socket 7.

The dove-tail portion 6 is provided with a threaded aperture 14 through which extends a bolt 15. The bolt 15 also extends through the longitudinally extending slot 16 carried by the vertical portion 9, so as to allow the vertical portion to be adjusted if it is so desired. 7 p

The primary portion of the clamp is provided. with shaped yoke 17- having laterally extending ,apertured ears 18, which ears are adapted to fit over theforwardly extending bolt portions 19 of the auxiliary-portion 20 of the clamp. The auxiliary portion 20 of the 190 clamp is provided with an upwardly extending, tapering lug 21, which lug is provided with a substantially V-shaped notch 22 forthe purpose of receiving the crank pin of a drive wheel, as will be hereinafter fully de- 9- scribed. It should be understood that nuts 23 may be placed upon the upper ends of the upwardly extending bolts 19 for firmly clamping the primary and auxiliary sections of the clamp together. I g

It should be understood that the structure illustrated in Fig. 3 of the drawing is, of

a substantially inverted V- 5 course, a sectional view through the base plate and the bottom of the resistance post. It is thought unnecessary to illustrate the combination of a resistance post and actual use of the device in view of the fact that any persons skilled in the present art may readily comprehend the method in which the resistance post is shown supported upon the base. The important changes of features embodied in the supporting device for the resistance post comprises a. base 25 which base is provided upon one side thereof with a longitudinally extending conical shaped rib 26 which constitutes a track for one side of the resistance post 27 clearly illustrated in Fig. 3. The resistance post 27 carries a plurality of wheels '28 which wheels travel upon the upper face of the base 25 for facilitating the moving of the resistance post longitudinally of the face. The opposite side of the resistance post 27 rests upon the upper face of the base '25 as indicated by the numeral 29.

This resistance post 27 may be secured upon the base 25 by means of the adjusting screws 37 which are provided throughout the length of the base 25 with a plurality of threaded apertures 31 as indicated in Fig. 8 of the drawing for receiving the bolts 30 and holding the resistance post 27 in an anchored position. It should be understood that the rib 26 is machined on all three faces and fits in the notch 26' formed in the under face of the resistance post 27. This rib 26 is preferably five feet in length and is formed integral as above stated with the base .15. It should be understood that the ram is adapted to move within the groove 4 illustrated clearly in Fig. 2 and slide out of the guide for permitting the pin clamp to be secured to the pin prior to the time at which the wheel is being pressed upon the axle.

The method of operation is as follows:

. Both wheels are pressed on the axle approximately 11-" and while the wheels are being pressed upon the axles, the wheels are kept in approximate alinement with the loose keys. It should be understood that the axles are provided with longitudinally extending key ways and that the wheels are also provided with longitudinally extending key ways, having a key placed therein and fitting loose. The keys are then removed and the rams are brought forward and the clamps are tightened on the pins by forcing the primary portion of the clamp downwardly upon the auxiliary portion 20 and causing the pin to be clamped between the inverted V-shaped jaw 17 and the notch 22. After the pins have been securely fastened within the clamp the wheels are then pressed to place.

It, of course, should be understood that in actual operation, an axle is suspended upon the usual suspending hooks employed in connection with a hydraulic wheel press such as a press of the Milles type and the wheels are then in turn pressed on the axle for a short distance. The arm carried by the resistance post is then moved outwardly and the clamp of the arm is bolted securely to the pin of the wheel. The same operation is gone through with the arm and clamp of the cylinder casting but it should be understood that unless the wheels should accidei'itally be spaced correctl y, the jaws of the clamp l0 as illustrated in Fig. 6 will. not touch the pin on both faces of the jaws. Under ordinary circumstances, this posi tion will be usually assumed, by the wheels.

The press is then operated for the purpose of pressing the wheels upon the shaft. The bolt as illustrated in Fig. l is then loosened and while the wheel is being pressed on the clamp as illustrated in Fig. 4, the same is drawn until the pin is in contact with the four faces of the clamp. It should be borne in mind that the wheels of the axle while being pressed may be easily i turned, notwithstanding the fact that the pressure may be tons. The axle is pressed on to the wheel at the resistance post and the wheel is pressed on the axle on the cylinder end.
