Patented Nov. 7, 1939 FATENT UFHQE PQRTABLE STAND Robert B. Peeler, Warren, Ohio, assi nor to Beaver Pipe Tools, 1110., Warren, Ohio, a corporation of Ohio Application May 24, 1937, Serial No. 144,375

1 Claim.

invention relates to a portable stand adapted normally to'support its load with proper rigidity when the stand is stationary, but readily convertible into a wheeled support, so that the load may be conveniently moved from place to place while on the stand. My stand has been especially designed for supporting comparatively light machine tools, as for instance pipe threading machinery, which while too heavy to be entirely lifted and carried about by one man may be readily rolled by him about the shop.

To the above end, I have provided a stand which may be made of structural shapes and plates welded together, the top of which is secured to the bed plate of the machine to be carried. The stand at one end may support an axle with a pair of wheels, the peripheries of which do not touch the floor. Provision is made, however, for securing the axle to the frame in a lower position where the wheels rest on the floor,

and carry that end of the stand above the floor level.

Adjacent the top of the stand I provide a pair of shiftable parallel rods. When these rods over- 25 hang the end of the stand where the wheels are located, they enable that end to be readily raised so that the wheel axle may be mounted in the lower holder and support that end of the stand above the floor. Then when the rods are 30 shifted longitudinally beyond the other end of the stand, they form handles by which the operator may lift that end of the stand and roll the whole device along the floor.

My invention is illustrated in the drawings 35 thereof, and is hereinafter more fully described with reference to those drawings.

Fig. 1 is a side elevation of my stand, with an illustrative machine tool mounted thereon. Fig. 2 is an end view of the stand. Fig. 3 is a detail 40 of the axle support, being a fragmentary vertical section on the line 33 on Fig. 2, looking toward the stand. Fig. 4 is a perspective of the stand below the bed of the supported machine. Fig. 5 is a detail at one corner of the stand, as

45 indicated by the line 55 on Fig. 4.

As shown in Figs. 1, 2 and 4, my stand has four vertical legs at the four corners of the rectangle, those shown being designated l, 2 and 3. The four legs are effectively positioned by suit- 50 able bracing plates and bars welded to the legs. The legs l and 2 are of the same piece with a top portion 5, these parts being made from an angle iron bent as shown. The other two legs are similarly formed. The two top portions, 6

and l, are effectively secured together by a top plate 3. The legs are braced by longitudinal braces H! and ii and transverse end braces l2 and 13, formed of angle irons and carrying a plate l5 which forms a horizontal brace and acts as a tray. Suitable gusset plates It may also 6 be employed.

At the bottoms of the legs l and 2 is secured longitudinally extended foot plates 18, while the other legs preferably have outwardly extending foot plates i9. 10

As shown in Fig, 1 the bed plate 29 of the machine tool rests on the top plate 8 of the frame. This bed plate 23 is bolted at 2|, by bolts extending through the top plate and through the adjacent flanges of the stand members 6 and 5, 1, so that the bed plate in effect becomes the top of the stand.

At each side of the bed plate 2!] are a pair of aligned ears 2% and in each pair of ears is mounted a longitudinal rod 26, which may conveniently be a pipe having having caps 21 on its ends, the rod thus having a limited longitudinal movement beyond either end of the stand.

The wheels which are normally idle, but may support one end of the stand, are designated 39. 25 They are mounted to turn freely on an axle 3i. Mounted on the axle some distance in from the wheels are a pair of collars 32, having crowned outer faces as shown at 33. On each of the legs I and 2 is a cleat formed by a block 35 on the outer face of the leg, and a plate-like portion 36 secured to the block and extending above and below it. These parts are welded together and to the legs, as illustrated. They provide a pair of upwardly facing laterally open receptacles 31, and a similar pair of downwardly facing laterally open receptacles 38.

Normally, when the stand is supporting its load in use, the wheel axle rests in the receptacles 81, which supports the wheel a short dis- 40 tance above the floor, as indicated in full lines in Figs. 1 and 2. However, if it is desired to roll the machine from one place to another, the operator lifts the wheels, removing the axle from the receptacles 31, and places the wheels on the floor with the axle adjacent the outer face of the plates 35; then drawing the rods 25 toward him to the limit, and using such projecting rods as handles, he lifts the adjacent end of the machine slightly, and then shoves the axle against the lower portion of the legs I and 2, and then lowers the stand so that the axle occupies the receptacles 38. In this operation the crowned collars 32 act as cams to laterally position the axle and keep the wheels properly spaced beyond the legs,

Now by shoving the rods 25 in the opposite direction to their limit, the operator has converted the machine into a two-wheeled wheelbarrow, and by using the projecting handle is able to lift the other end of the stand and roll it to a new position. Thereafter, he reverses the position of the rods, lifts the machine at the wheel-end, freeing the wheel axle and then lowers that end to the floor and restores the wheels to their normal idle position.

By making the rods 25 shiftable, one avoids having them normally projecting unduly at either end of the machine, where they might be in the way of the operator.

The bed 20 may carry any machine tool which the stand is adapted to support. I have illustrated a pipe threading machine made after the manner of my Patent No. 1,947,874, issued February 20th, 1934, to my assignee, The Borden Company, now known as Beaver Pipe Tools Inc. As shown in Fig. l, the supported machine comprises a hollow frame A, carrying a rotary chuck B, a longitudinal shiftable cariage C, which may carry for instance a pipe cutter D, and a ring E having inwardly projecting threaded dies. A motor F may drive suitable gearing not shown. within the hollow frame to operate the chuck.

The stand described with the exception of the machine bed plate 20, is made up of angle irons and plates welded together, and thus is light and at the same time strong in construction. The bed plate of the machine, which makes in effect the top of the stand, is bolted to the parts directly below it. By mounting the slidable rods on this bed plate, they may serve also as a means by which men may carry the machine itself when the bed plate is freed from the frame.

I have found that the shifting of the rods and the lifting of the end of the frame, and the repositioning of the wheels may be effected very quickly. The operator when he lifts the wheels from their normal support, ordinarily places them with the axle raised against the outer face of the receptacle plates 36, and then by lifting that end of the machine he can with the toe of his shoe shove the axle towards the machine so that when the machine is lowered the axle is automatically repositioned. If desired, the intermediate portion of the axle may be square so as to fit with desirable snugness in either of the rectangular receptacles, while allowing it to be readily removable.

It will be noted particularly that the wheels 30 are comparatively large, so that they may readily roll over a rough floor or even on the ground, thus accomplishing a much better result than small wheels or casters. By having such wheels entirely above the floor level when idle, the machine has the desired firm support for use. The wheels are carried in that end of the machine which is distant from the position of the operator, in front of the carriage, and thus do not interfere with him in any manner.

If desired, the space in the stand above the horizontal bracing plate l5 may be open, such plate constituting simply a tray for any convenient storage. On the other hand, this space may be closed to provide a storage compartment, by vertical plates carried by the legs. In this case, there are fixed vertical plates at the ends and one side of the machine, while at the other side I provide a removable vertical plate enabling access to the compartment.

As illustrated in the drawings, the storage compartment just referred to is closed by a vertical plate 40, the lower end of which extends freely behind the upper flange of the brace bar l0, while near the top of this plate is an opening through which a staple 4| depending from the top plate 8 may pass. This staple may, for instance, receive a padlock (not shown), and the plate may have a suitable handle 43 by which it may be lifted.

I claim:

A portable stand having legs, a removable axle carrying a pair of wheels, means carried by the legs at one end to support the axle with the wheels above the floor, and also to engage the axle when the wheels are on the floor and the legs above the floor, whereby that end of the stand may rest on the legs or on the wheels as desired, and a pair of slidable rods adjacent the top of the stand adapted to project beyond it at either end.
