15 Claims.

The present invention relates to industrial tables and more particularly to supports for work boards, which, as a matter of example, are suitable for use by furriers.

A use for the device concerned with herein, is where comparatively large boards are used to have fur pelts nailed onto both surfaces thereof. It usually requires two persons to lift such board onto trestles or other table-top supports, turn such board over when required and thereafter remove it from such supports to make room for the next board to be worked on.

An object therefore of this invention is to provide a novel and improved supporting means for a board or the like, whereby it is convenient for one worker to lift the board onto or oil the trestles, or turn same over thereon.

A further object hereof is to provide a board supporting means of novel and improved construction, adaptable for boards of various area sizes.

Another object of the present invention is to provide a novel and improved device which enables manipulating the work board as mentioned, and which-can be made as an attachment for existing trestle or other supporting structures.

A further object hereof is to provide a novel and improved device of the character described, which is simple in construction, reasonably cheap to manufacture, easy to use and efiicient in carrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosure proceeds.

In the accompanying drawings forming part of this application, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 is an end view of a work board and a supporting means therefor embodying the teachings of this invention; said board being shown in a manually held position.

Fig. 2 is a section taken at line 2-2 in Fig. 1.

Fig. 3 is a section taken at line 33 in Fig. 2 with the table resting on the supporting structure.

Fig. 4 is a-perspective view showing a bracket included in said embodiment.

In the drawings, the numeral [5 indicates a work board and I6 any suitable supporting means therefor, as for instance the pair of horses I1 and 18 which are in spaced relation thereunder. Mounted underslung on the respective top rails of said horses or trestles I! and I8, are the brackets 19 and 20 respectively. Bracket l9 carries the tubular member 2|, while bracket 20, carries rod member 22; said members 2| and 22 being in telescopic relation. The numerals 23 and 24 are bolts for securing said telescopic members to the respective brackets, while 25 is a thumb screw to maintain said members in a definite relation. Thus far described, is a telescopically adjustable table-top supporting structure. At the remote ends of such structure are the respective foldable braces designated generally by the numerals 26 and 21. Brace 26 comprises a link 25 pivotally mounted at one end at 28 to member 2| and another link which may be of the extensible type as 26", pivotally mounted at one end to a board clamp 29 at; the other ends of said links being in pivotal relation by pin 3|. Brace 21 is of identical structure. The links comprising same are identified by the numerals 27' and 21". Pivotal connections are 32, 33 and 34, while 35 is the associated board clamp. The clamps 29 and 35, are comprised of the respective channel-pieces 29' and 35, and the respective thumb screws 29" and 35", to engage board l5.

For use, the horses I! and I3 are spaced apart as far as is practical and bolts 23 and 24 tightened, as well as thumb screw 25, so that the clamps 29 and 35 are a proper distance apart to receive board l5 between them. The extensible links 26" and 21" are adjusted by means of the respective set screws 36 and 31, so that the total length of the braces 26 and 21 shall be identical when extended and suflicient to permit the board i5 when mounted to be turned to clear the horses I! and It. A board l5 to be worked on, is then placed with its forward edge resting on the floor and a surface thereof resting against said horses, meaning a position'indicated by the numeral l5 in Fig. 1. The clamps 29 and 35 are mounted substantially centrally onto the side edges of the board [5. The entire assembly being of sturdy construction, board I5 is taken hold of at its side edges near the floor in its position l5 and its lower end lifted, at the same time sliding said board along the top rail of said horses until it lies in position [5". To reverse the position of the board so that what was its underside shall face uppermost, said board is taken in hand, its forward end is then lifted and pulled forward, and said board can thenbe turned about while its rear edge slides forward atop the horses. All such manipulation of the board I5, can be accomplished easily by only one person. Once the device is set up for the largest size board; and if the widths of the boards used are not at great variance, the only adjustment which need be made is for length, requiring only adjustment of the telescopic brace members securedby thumb screw 25.

To aid initial lift of the board I5, a lever 33 may be provided, rotatably mounted on rod 22, intermediate the ends of said lever, and dimensioned so, that it is balanced so that it does not revolve of itself when board I5 is off the trestles l1 and i8.

When the boards used are of uniform size as to their widths, the adjustability afforded by links 26" and 21" may be omitted, and if also of uniform length, the adjustability of spacing the horses, may be omitted.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desiredthat the embodiment shown herein be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; reference being had to the .following claims rather than to the specific description and showing herein to indicate'the scope of the invention.
