MOTOR-STAND.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed July 7, 1917. Serial No. 179,226.

To all whom it may concern.-

Be it known that I, WILLIAM JAMES ADAMS, a citizen of the United States, residing at Cochranton, in the county of Crawford and State of Pennsylvania, have invented a new and useful Motor-Stand, of which the following is a specification.

Thesubject of this invention is a motor I stand wherein a motor holding frame is adjustably secured between supporting standards, and the objects of the invention are, first, to provide a motor support which may be adjusted to various positions, second, to provide a motor support with a frame within which a motor may be hung and means for adjusting the frame to various positions, third, to provide a motor supporting frame adjustably hung between standards and clutches for securing the frame in its adjusted positions, fourth, to provide means for adjusting the frame to various sizes of motor, fifth, to provide means for locking 1 the side bars of the frame against turning,

sixth, to provide means for readily transporting the frame with the motor supported therein to different parts of the shop, seventh,to provide a simple and efficient motor stand.

With the foregoing 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 the invention hereinidisclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawings,

wherein Figure 1 is a side elevation of the device.

Fig. 2 is a top plan view of the device.

Fig. 3 is a central vertical cross section.

Fig. at is a detail sectional view taken on the line #lof Fig. 2, parts being removed.

Fig. 5 is a detail showing an end bar of the adjustable frame in elevation.

Fig. 6 is a plan view of the same.

Fig. 7 is a detail sectional view on the line 77 of Fig. 6.

Fig. 8 is a detail perspective view of the end of one of the side bars of the frame.

Referring to the drawings by numerals of reference:

The stand is provided with the supporting legs 1, four being shown in the present in stance, arranged in pairs at each end of the stand. At the lower ends of one pair of legs 1 are mounted brackets 22 which turn on the legs but are normally held against turning by the pins 3 on which are threaded nuts 4. J ournaled' in the end of each bracket 2 is a roller 5. The object ofthis construction is to allow the stand to be raised at one end, the legs being used as handles, and propelled from one location to another on the rollers 5. Each pair of legs 2 is tied together at a median point by an angle plate 6 which is secured to the legs by bolts 7 or otherwise. The tops of each pair of legs are joined by a tie plate or casting which is r formed with an angularly disposed upper flange or top 8 preferably formed with circular ends as shown which are adapted to seat upon the upper ends ofthe legs 1, and with curved ends 9 which form grooves for the reception of the legs 1. This tie plate is secured in place on the legs by bolts 10, or otherwise. Each tie plate is formed with a centrally disposed, laterally extending boss 11, which may be integral with the plate or attached thereto, and which is formed with an annular rib or tongue 12 and a central bore 36. Each boss forms a member of a clutch which will be hereinafter explained. The pairs of legs are bound together by tie bolts 13 which pass through apertures formed in the vertically disposed'portion of each angle plate 6 and which are surrounded by spacing sleeves or tubes 14. i

g A frame is adjustably rovoluble within the support'just described, and this frame is composed of end bars each of which is formed of a central channel bar 15 in the longitudinal channel of which slide the end members 16. Each member 16 is formed with a longitudinal slot 17 through which passes the shank of a set screw 18 which is threaded to engage a threaded aperture 19 formed in the channel bar 15. This set bore 21. Extending from each boss 20 to ward the inner end of the end member, is a longitudinalrib 22. The rib 22 is adapted to take into a notch 23 formed in the end of each tubular side bar 24. The side bars 24: are bound in place between the end bars by tie bolts 25 which extend through the bores 21 and the bores of tubular side bars and are bound in place by nuts 26 which are threaded on the ends of the bolts. The side bars as will be apparent, are held against turning on the bosses by the ribs 22 which engage the notches 23 as just described.

On each side bar 24 are adjustably secured inwardly projecting arms 27 each of which is provided at one end with a hub 28 through which the side bar 24 passes. A set screw 29, passing through the hub, serves to clamp each arm 27 in place, when adjusted. A clamping plate 30 is pivoted on each arm 27, and overlies a portion of the same and may be clamped upon the arm by a set screw 31. A boss 82 may be formed on each arm 27 and underlie the outer end of the plate 30 to place the plate in proper position to be clamped.

The method of adjustably mounting this frame within the support is as follows:

Each channel bar 15 has secured to its outer face, by rivets, or otherwise, a boss 33 which is formed with an annular tapering groove 34- adapted to receive with close binding fit the annular tongue 12. Each boss 34L is formed with a central bore which is tapped'to receive the threaded end of a hand screw 35 which passes through a bore 36 formed through the center of each boss 11 hereinbefore mentioned. The hand screw 85 is formed with an enlarged cylindrical head 37 the inner end of which is adapted to abut the outer face of the top tie plate or casting. A cross bar 40 is suitably secured to the head 37 and serves as a handle by which the hand screw 35 may be turned.

From the foregoing it will bevseen that the supporting arms 27 may be adjusted to accommodate motors of various lengths; that the side bars may be adjusted toward or away from each other to receive motors of various widths; that the frame may be revolved to any position and there held to permit work on any part of the motor; and that the legs at one end of the stand may be grasped near the bottom and elevated so that the device will be supported on the rollers ,5 when the stand may be easily moved from place to place about the shop.

Copies 0! this'patent may be In practice the device is used as follows: The device being set up, a motor 41, in dicated in dotted lines Fig. 3, may be put in place by turning the plates 30 to one side,

- placing the motor within the frame with the flange between the motor proper and the crank case resting upon the arms 27 turn clamping plates 30 into position resting upon the flange at the thick part where bolts go through and clamp down with set screws; adjust the frame to any desired positi on by turning the hand screws 35 to release the clamps, and when the frame is adjusted to the desired position again turning the hand screws 35 to engage the clamps.

Having described the invention, what is claimed as new and sought by Letters Pat'- ent is:

1. In a motor stand, a frame comprising tubular side bars provided with a notch in each end, adjustable end bars, a boss on each end of the end bars and adapted to enter the bore of the side bars, a rib eXten'dinglongi tudinally of each end bar and adapted to enter the notch, and means for clamping the side bars between the end bars, means for securing a motor within the frame, a sup port, and means for adjustably securing the frame to the supports. 7

2.'In a motor stand, a frame comprising side bars provided with a notch in each "end, end bars, a rib on each end bar and adapted to enter the notch, and means for clamping the end bars to the side bars, means for se curing a motor within the frame, a support, and means for securing the frame to the support.

3. Ina motor stand, a frame comprising side bars provided with a notch ineach end, end bars, a rib on each end bar and adapted to enter the notch, a clutch element on each end bar, and means for clamping the end bar to the side bars, means for securing a motor within the frame, a support, clutch elements on the support, and adapted to engage the cl-utch elements on the end bars of the frame, and means for drawing the'clutch elements into contact to hold the frame in adjustedposition within the support.

In testimony that I claim the foregoing as my own, I have hereto affixed my sigmature in the presence of two witnesses.
