1 Claim,

This invention relates to a folding vise stand and has for one of its objects the production of a simple and efficient folding vise stand having a maximum strength and so constructed as to eliminate lost motion when in a set-up position, the stand being light in weight and being easily and quickly set-up.

A further object of this invention is the production of a simple and eicient vise stand espeeially adaptable for use by plumbers and the like, one important feature being the bracing element between the folding legs and the visesupporting table.

Other objects and advantages of the present invention will appear throughout-the following specification and claim.

In the drawing:

Figure 1 is a perspective View of the stand in a set-up position; a, certain portion thereof being shown in section;

Figure 2 is a side elevational view of the stand in a folded position, a certain portion being shown in section;

Figure 3 is a horizontal sectional view taken on line 3 3 of Figure 2;

Figure 4 is a vertical sectional View taken on line 4 4 of Figure 3;

Figure 5 is a. vertical sectional view taken on line 5 5 of Figure 1;

Figure 6 is a horizontal sectional View taken on line 6 6 of Figure 1; and

Figure 7 is a vertical sectional View taken on line I 'I of Figure 6.

By referring to the drawing, it will be seen that I0 designates the table portion or table top of the vise stand which 'is preferably square in formation having beveled side edges II. Three ribs I2 are formed upon the bottom of the table top I6 and are preferably formed integral therewith, and these ribs are arranged to provide a Y-shaped channel I3 upon the bottom face of the table I6 so as to support the front leg at an angle of approximately twenty-two and one-half degrees with respect to the sides, and the back legs at approximately a ninety-degree angle with respect to the back of the table.

Legs I4 are pivotally secured within the Y- shaped channel between the ribs I2, as shown in Figure 3, the legs being pivotally secured in position by means of bolts or other securing means I5, the legs being preferably three in number. These legs diverge from each other at their lower ends and are provided with notched feet I6 through which feet may extend anchoring screws Il, or other suitable anchoring ele- 24e-fin) ments A hollow depending tubular guide or pipe I8 is secured to the center of the table top II] and extends therethrough, as shown in Figure 4. A lock nut I9 is threaded upon the upper end of the tubular guide I8 and abuts against the under face of the table top I0 and a beveled washer 20 is threaded on the extreme upper end of the tubular guide I8 to lock the guide firmly in engagement with the table I0.

A vertically extending bracing rod 2I is slidably mounted through the tubular guide I8 and this bracing rod 2l is provided with a threaded upper end 22, and a threaded lower end 23. A slidably mounted collar 24 is carried by the lower end of the bracing rod 2I and abuts against the lower end of the tubular guide I8 When the table is in a set-up position. A binding nut 25 is threaded upon the lower threaded end 23 and engages the collar 24 to hold the collar 24 in abutting relation with respect to the lower end of the tubular guide I8 when the table is in a set-up position.

A plurality of flat radiating braces 26 are hingedly secured, as at 2l, to the collar 24 at their inner ends, and the braces 26 are hingedly secured at their outer ends, as at 28, to the legs I4, as shown in Figures 1 and 7. These braces 26 may be of suitable design to efliciently brace the legs I4 when in an extended position, and at the same time constitute a securing element when the legs are in a folded position, as is shown in Figure 2. A nut 29 engages the upper threaded end 22 of the bracing rod 2I when the table is in a set-up position and this nut is engaged by a swivel link 38, which swivel link is anchored to a chain 3|, the chain 3| being secured, as at 32, to the under face of the table.

The table portion I6 may be provided with a bead IIa around the upper edge thereof to hold articles, such as oil cans and the like, on the top part of the table, and prevent them from slipping off the table.

From the foregoing description it will be seen that a very simple and eflicient, as well as sturdy, vise stand has been provided which will very firmly and securely support the table IIJ when the legs are in an extended position, as is shown in Figure 1, and it will also be noted that the rod 2l will constitute an efficient brace when the

nuts

29 and 25 are threaded on the

respective ends

22 and 23 and are moved to a binding position. When it is desired, however, to transport the stand from place to place, the nut 29 may be removed and the bracing rod 2I may slide down into the tubular guide I8, as shown in Figure 2,

thereby permitting the legs I4 to be swung to an approximately parallel position. When the vise stand is in a set-up position and the screws I'I are anchored into the oor or other support, and the

nuts

29 and 25 are threaded into binding position, the table will be rmly and thoroughly braced. For temporary Work, however, when the

nuts

29 and 25 are threaded to a binding position and the legs I4 are moved to the position shown in Figure 1, the parts will be suiciently braced Without the anchoring screws I1 to provide a sturdy and efficient support. When the screws I'I are used, the notched feet I6 will be forced rmly against the screws as the nut 29 is threaded down upon the upper end 22 of the rod 2I. The table I0 may be provided with

suitable apertures

33 and 34 to receive anchoring means for a vise or other element or tool which may be mounted upon the table II.

From the foregoing description it should be understood that certain detail changes in the construction and arrangement of parts may be employed without departing from the spirit of the invention, so long as such changes fall Within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A folding vise stand of the class described comprising a table top, spaced integral ribs arranged to form a, Y-shaped channel upon the bottom face of the table, legs pivoted in said channel between the ribs and adapted to be extended in diverging relation to support said table top, the legs having means for anchoring the lower ends thereof to a support, a hollow tube depending from and extending through the table top, a bracing rod having an inner end slidable in said tube, radiating at braces horizontally hinged to said rod at one end and to the legs at their opposite ends to resist lateral strain when the legs are in an extended position, and means engaging the inner end of the rod and abutting the top face of the table top to hold the rod in a set position within the tube and thereby preventing the legs from spreading.
