PIPE VISE STAND.

the following is a specification.

This invention relates to pipe vise stands, having: particular reference to portable and collapsible stands of this character, an important object of the invention being to provide avise stand of comparatively light cor.- struction so that. the same may be readily carried about or transported, which may be compactly folded so as to be easily handled, which occupies but a small amount of space when collapsed, which may be easily set up when required, which will provide a rigid structure when set up, and with which a variety of types or sizes of vises may be used. i

A further object is to provide a stand or bench ofthe general character set "forth which is of such construction that the strains to which the same must necessarily be subjected when in use will be equally distributed to all of its supporting elements, whereby rigidity of the stand when in use is at all times assured and wobbling of those is obviated.

ll. Further object is to provide improved means for maintaining the stand firmly in operativefor erected position, and in the manner of mounting the said mezins upon the stand.

The invention'has for a further object to provide a stand ofthat' character wl'ierein a vise table or bench is employed. also a foot board or platform associated with the stand. and whereby means of an improved nature is used for connecting the frame to the table to permit of the latter assuming certain positions when collapsed, and further characterized by improved connections between the said platform and the stand.

ll ith these objects in view. together with others which will appear as the description proceeds. the invention consists in the novel construction, combination and arrangement of parts. all as will be described more "fully hereinafter, illustrated in the accompan ing drawings, and particularly pointed out in the claims.

The base or platform or table upon. which the viseis to be attached is indicated at 13,

and comprises a plateoit'me-tal or other ma terial of sutlicient size to ac-commodatethe vise and to resist the pressures to which the table must necessarily be subjected. The

table is preferably such type that .va-

rious sizes or styles of Vises may be accommodated, in order that the stand maybe employed in a number of uses, and any preferred means may be resorted to in adapting the vise to the table. It will be understood, of course, that devices other than vises may be applied to the table if desired, and though the invention is 'described as designed primarlly tor the ac-/ eommodation' of vises, its use is not to be understood as being soconfi'ned. Near the rear end of the table there is provided a former l5, affording means whereby pipes or rods may be bent. or shaped, as will be understood. I

The stand for the vise bench or tableis indicated generally at'17, and. comprises front and rear legs 18 and 19 respectively,

These legs are arranged in pairs as Shown,

the legs of each pair being disposed relatively far apart at their lower ends to insure stability, and being extended inwardly toward each other at their upper ends to be secured to the under side of the table 13. In the present instance,the legs of the frame are formed of pipe of relatively small diameter, which will prove suiliciently strong in practice to bear the weights and strains incident to the use of the vises, yet being of such light weight to permit of the device being easily handled. Other material, however, may be used in constructing the supporting frame. The front legs of the frame are tied together near their lower ends by a cross bar or rod 20, while the le s of the rear pair are similarly connected by the bar 21; these tie rods thus acting to stabilize the frame, to hold the legs of each pair true, and to assist in distributing the weights and strains equally to all parts of the frame. W hen in set up position, the front legs are disposed at substantially right angles to the table 13, while the rear legs extend rearwardly beyond the table at an inclined angle therewith. The rear legs are therefore longer than the front legs, and near their outer or free ends are bent or inclined downwardly as shown and provided with feet having relatively sharp prongs 22- to engage in the ground or a floor to prevent-slipping.

The upper ends of the legs are pivotally or hingedly connected. to the table l2. To facilitate this connection, spaced apertured projections or members 23 are provided for each of the front legs, the said members in this instance being formed integral with the table 13. The rear end of the table is provided with depending rearwardly inclined projections 30, the lower ends of which are bifurcated as shown to receive tongues 31 at the upper ends of the rear legs 19. The tongues 31. are formed upon the caps or nipples 32 attached to the legs, and are provided with longitudinally disposed slots 32 to receive pins 33 carried by the projections 30. The upper ends of the tongues are each provided with toes 34 to engage behind shoulders at the bases of the furcated portions of the projections 30; such interlocking engagement of these parts only taking place when the projections 30 and legs 19 are in true alinement with each. other and when the pins 33 are at the bases of the slots 32. vVhen thus positioned the legs 19 will be held against forward swinging movement by engagement of the toes behind the said shoulders, and the legs 19 will be prevented swinging rearwardly by engagement of the surfaces 36 the tongues 31 with the surfaces 37 at vthe cases of the bifurcated portions.

The front and rear legs of the frame are connected by the collapsible or foldable brace indicated at 88, to hold the legs against collapsing. This brace comprises the arms .-394 O, the former being pivotally connected to the frontlegs at one end, while the rear ends of the arms ii) are similarly connected with the rear legs of the frame. The adjacent ends of these arms are pivoted together in overlapping relation, and the overlapping portions of the forward arms overhang and rest upon the adjacent portions of the rear arms all to prevent the said arms moving downwardly out of alinement with each other.

A tiny at is hinged between the forward legs of the frame and when swung down-' w idly rests at its free end upon the arms 39. This tray is capable of swinging upwardly when the device is to be collapsed, and when extended in horizontal position affores a holder for tools, supplies, etc, of the workman,

The forward ends of the brace members 3) are pivoted as 42 between spaced lugs =18 t the rear ends of clamp sections l4 45, the latter being of arcuate shape and when assembled forming sleeves conformllla to the size and shape of the legs 18 of the frame. The forward faces of section are slotted and receive ton ues 46 on sections 44:; this construction securely yet etachably locking the forward ends of the sections together, while the rear portions of said sections are detachably held together by belts or screws The leg 19 the rear of the supporting frame are closer together than are the legs i s of the front pair, inorder that the'frame be properly collapsed! and rendered com pact and the rearends of arms All) of he foldablc brace must therefore be at tached to the outer side of the said rear legs. "to the outer side of each rear leg is a tached, by a screw 50, a block 51, the latter being channeled as at 52 upon each 110 side to conform to the contour of the leg If), and it will be seen that When the screw 19 is tightened the block will be held securely upon the leg and against rotative u'iovement thereon. By channeling the block upon both its inner and outer faces, the said blocks are rendered adaptable to both the right and left hand legs of the rear pair. The upper end of each block is provided with angularly and forwardly projecting spaced cars 53, between which the rear ends of brace arms 40 are pivoted, as at In connection with the stand, I provide a platform upon which the workman stands, the said platform in addition to affording a comfortable and dry foot rest for the workman, enables the weight of the latter as tin. stabilizing the frame. This platform is indicated at 55, and comprises 130 a frame formed preferably of angle iron having three sides, the channel or open sides of the frame affording pockets or rests for the transversely disposed platform slats 56. The extremities of the channel iron frame carry clevis members 57, the latter being secured to the irons by rivets or bolts, and the opposite ends of the irons are tied together by the tierod or bolt 58. The clevis members receive the lower ends of the feet 59 of the front legs of the fraine, the said feet being pr vided with longitudinally disposed slots or recesses 60 to receive pins (31 carried by the clevises. Thelowcr ends of the feet 59 are provided with forwardly projecting toes 62 adapted to engage and interlocltwith the shoulders 63 in the clerises when the legs of the frame and the plat form are disposed at right angles to each other, as shown in Fig. 10.- lVhen in this position, the rear portion ofthe foot of each leg will be in binding engagementwith the rear portion of their respective clev s s at a point above the pivotal connection of the leg with the clevis. The rearward strain of the frame will therefore be borne by the clevises, while upward movement of the legs will be restrained by engagement of the toes with the shoulderportions 63 of the clevis portions .Theaea surface of each foot of the forward legs is rounded as at 65, to permit of the feet being turned in. the clevises after the toes of the feet have been Withdrawn from engagement with the shoulders of the cle'vises; the said curved or rounded portions permitting the feet being retracted sufficiently to cause such disengagement; affording a rigid connection between the legs and platform when disposed at right angles to each other, enablesthe platform to be easily swung upagainst the front legs of the frame to assume. a position in a spaced plane wherewith.

In use, the frame will assume the position shown in Figs. 1 and 3. When so set up, the prongs of the rear legs are engaged in the ground or floor, and the shoulders at the point of connection, of the rear legs with the table projections will be interlocked, as above described. The clevises and feet of the frame will also be locked together, as shown in Fig. 10. The tray 41-1 will be swung to horizontal position and will rest upon braces 38. T he strains to which the frame will be subjectedinci dent to work being done upon the table will be delivered equally to the front and rear legs of the frame, also to the braces 38 and the connecting tie rods of the front and rear legs respectively. Work performed upon the table by the workman standing upon the platform 55 will necessarily subject the framev to rearward strain, and the rear leg are disposed at the angle This construction, while the position shown in'FigLQI, spaced from the front legs, and the lower ends of the front and rear legs will be disposed in substantially the, same plane] The table will have passed through a 1novenient"'of sub; stantially ninety degrees, a1id,will be dis-- posed at a slight angle to the front a1 rear legs of the frame. The platform will be swung upwardly'into substantially the'same plane with the table, inthe manner above described so that the stand will oce eupy a comparatively small amount of space and may be easily carried or transported.
