PATENT OFFICE] JAMES 'A. LONG, 01 READING, PENNSYLVANIA, ASSIGNOR TO PENN ENGINEERING COMPANY, OF READING, PENNSYLVANIA, LONG, CLEVE E. LONG, J. EDWIN TOTHERO A PARTNERSHIP 'COMPOSED OF JAMES A. AND HARRY A. KISSINGER VISE STAND Application filed November 27, 1929. Serial .No. 410,130.

The invention relates to improvements in stands such as those commonly used by plumbers, steam-fitters and other mechanics for supporting vises, pipe benders or other equipment;

It is one object of the invention to provide a new and improved construction for connecting' the legs with the top plate and allowing said legs to swing inwardly from ope-rative inclined positions to substantially vertical ositions, the construction being such that tiiere is no danger of breaking any parts of the pivotal connections during/ordinary use, or during shipment or rough handling.

A further object is to provide novel means for limiting the inward swinging of the legs.

A still further aimis to make unique provision for holding the legs against accidental inward swinging.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the ac companying drawings.

Fig. 1 is a rspective vie-w wlth the lower portions of t e legs broken away.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional view on line 3-3 of Fig. 2.

In the drawings above briefly described, the numeral 5 denotes a suitably shaped top plate provided with various openings 6 instrumental in attaching equipment thereto, with an opening 7 to receive a pipe to be bent, and with a pipe-bending rest 8. The

lower side of the plate is suitably ribbed as and legs, only one socket and leg will be specifically described.

The socket 10 embodies two spaced vertical side walls 13, an outer end wall 14 integral with said side walls, and an inner end wall 15 also integral with said side walls. The side walls 13 are preferably stepped so that greater length is imparted to the outer portions of the sockets 10 than to the inner portions, but this exact configuration is not essential.

The pivot 12 is spaced inwardly from both of the walls 1 L15, is spaced downwardly from the upper extremity 16 of the leg 11 and is spaced upwardly to a slight extent from the lower extremity of the outer end wall 14, and said leg extremity 16 is permanently spaced downwardly from the top plate 5. The relation of parts is such that when the leg 11 is swung outwardly to its operative position, said extremity 16 thereof abuts the end wall 15 while a portion of the leg below the pivot 12 abuts the lower extremity of the outer end wall 14. Hence, leg is effectively limited and said leg can exert no lever-like strain upon the pivot 12 tending to shear the latter. When the leg is swung inwardly to its 1 vertical position, seen in dotted lines in lig. 2, its extremity 16 abuts the outer end wall 14 and hence limits such inward swinging of the leg.

The opposed side walls 13 of the socket 10 are provided with inwardly distorted p0r-' tions 17 providing humps past which the leg the outward swinging of the retracted substantial 11 snaps when said leg is swung outwardly as the legs snap past the humps l7, incident to outward and'inward swinging of said legs.

By providing the novel construction shown and described or a substantial equivalent thereof, a stand is provided which will efiectively attain the objects of the invention.

The details disclosed have proven highly advaontageous from all standpoints and are preferably followed. However, within the scope of the invention as claimed, variations ma be made. i

claim 1. A stand comprising a top late having pairs of downwardly projectlng parallel walls, legs whose upper ends are pivoted between said walls in position to at all times clear-said top. plate, means for limiting the outward swinging of said legs to their operative positions, and humps integral with said side walls and projectmg inwardl therefrom in opposed relation with eac other, said humps being positioned to abut opposite side portions of said legs and hold the latter in their operative positions, portions of said stand having suflicient inherent resiliency to allow said legs to snap past said humps when swinging said legs to and from operative positions.

2. A tripod comprising a top plate having downwardly projecting socket members, each of said socket members having parallel side walls disposed substantially radially of said top plate, outer end walls integral with the outer ends of said side walls, andvinner end walls integral with the outer ends of said side walls,downwardlydiverginilegswhoseupper ends are reecived in said soc et members, and pivots below the'upper extremities of said legs passing through said legs and said side fixed'my signature. 4

walls and mounting the former to swing radially of said top plate, said pivots being dis- 4 posed to vcause said legs to abut both said inner and outer end walls when said legs are in downwardly diverging relation and to cause said leg extremities to strike said outer end walls when the legs are inwardly swung to substantially vertical positions.

3. A tripod comprising a metal top plate having downwardly projecting socket members, each of said socket members having parallel side walls integral with and dis posed substantially radially of said top plate, and inner and outer end walls integral with said top plate and said side walls, metal legs whose upper ends extend into said socket members, pivots passing through said legs and side walls and mounting said legs in position to at all times clear said top plate, said pivots bein posi- 'tioned to cause said legs to strike sai inner end walls above the pivots and said outer end walls below the pivots when-said legs are swung outwardly to operative position, and

to cause said legs to strike said outer walls above the pivots when said legs are swung inwardly to substantially vertical positions,

7 and hump integral with said side walls'and projecting inwardly therefrom in opposed relation with each other, said humps being positioned to abut opposite side portions of said legs and hold the latter in their operative po-
