DINKING- BLOCK SUPPORT.

APPLICATION FILED mum, 1911.

W/T/VESSES UNITED STATES PATENT OFFICE,

WILLIAM R. FORSYTH, OF SWAMPSCOTT, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

LOSQSOG.

To all whom it may concern:

Be it known that I, VVILLIAM R. F ORSYTH, a citizen of the United States, residing at Swampscott, in the county of Essex and State of hiassachusetts, have invented certain Improvements in Dinking-Block Supports, of which the following description, in connection with the accompanying drawings, is a specification like reference characters on the drawings indicating like parts in the several figures.

This invention relates to dinking block supports.

An object of this invention is to provide asupport for a dinking block in which provision is made for various adjustments whereby the support may be adapted to accommodate blocks of various dimensions and whereby the working face of the block may be maintained at a constant level.

Another object of this invention is to provide a support which may be collapsed and folded for shipment to avoid excessive freight charges.

In the drawings which illustrate a pre-' ferred embodiment of my invention,Figure 1 is an elevation of a dinking block support; Fig. 2 shows the support collapsed for shipment or storage; Fig. 3 is a section on the line w:c of Fig. 1.

In the continued use of a dinking block its vertical height varies owing to the resurfacing of its top or working surface which is made necessary by the wear of the block. It is, therefore, necessary to support the block at greater elevations as the height of the block is decreased in order to maintain the top or working surface at approximately the same level throughout the period of use fulness of the block. To this end, in the construction herein illustrated, uprights 1 are provided with a series of notches 2 in which looped clamp straps 3 may be seated,

thereby providing for the support of the transverse beams, comprising the parts at and 5, at any desired elevation. The uprights 1 are provided with grooves 6 into which fit tongues 7 formed upon the outer ends of the parts 4 and 5 of the transverse beams. It will be seen that the weight of the block 8 bearing down upon the clamps 3 tends to turn said clamps, retarded by the notches 2, into a plane of greater inclination to the horizontal and thus to draw the uprights and transverse 7 beams tightly to- Specification of Letters Patent.

gether. To adjust the elevation of the transverse beams, it is simply necessary to effect a reverse relative movement of each end of each beam and its associated clamp and to place the clamp in the proper notch.

Parts forming the far side of the support duplicate the parts shown in front in Figs. 1 and 2. The pairs of uprights are con nected at a suitable distance apart by the struts 9. The cross pieces 10 span the beams and rest in slots formed in the beams adjacent to their ends. The cross pieces 10 are provided at their ends with pins 11 which extend above and below the cross pieces. The lower extensions of these pins depend from the cross pieces, outside of the beams and the dinking block rests between, and is secured from, lateral displacement by the upper extensions of the pins The clamps are secured to the beams by means of bolts 12, the point of attachment of the bolts being near the bottom of the beams. Now it will be seen that if the beams are raised sufliciently high, the tension on the clamps will be released and (see Fig. 2 at the right) they will drop to a position on the uprights which will permit the uprights to be turned about the bolts to a position beneath and parallel with the beams. Thus arranged the device is in compact shape for shipment or storage.

As the dinking blocks vary in length, it is desirable to have a support that may be adapted to Various lengths of blocks. This device therefore includes extensible transverse beams as an important feature of the invention. These extensible beams are constructed of the two parts, 4 and 5, the part 4 having a tongued extension, see Fig. 3, and the part 5 having a grooved and slotted extension, see Figs. 3 and 1. Through the slot 13 of the grooved extension of part 5 clamping bolts 14 pass to fixed positions on the tongued extension of part 4-. It will be seen by the arrangement of the bolts let with relation to slot 13 that the extensible beams may be extended to vary the distance between the uprights 1 and thus vary the length of the bed of the support for various lengths of blocks. The tongue and groove construction serves to make the transverse beams more rigid and counteracts the tendency of the parts 4 and 5 to yield to the shearing force of their own weight when the bolts 14 are loosened, and the friction of Patented June 25, 1912. v

these parts on each other is thereby reduced for adjustment of the length of the beams.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A dinking block support, having in combination, means for clamping said support in various positions of vertical adjust-- ment, means for securing said block upon said support, and means for clamping said support in various adjustments of horizontal length, said device being so constructed and arranged that-it may be collapsed'without disconnecting said parts.

2. In a dinking block support uprights, longitudinally extensible transverse beams, means for clamping said beams to said uprights, and means for securing said clamping means to said beams, said parts being so constructed and arranged that while said parts are still connected said uprights may be drawn down relatively to said beams and turned about the clamp securing means until the said uprights reach a position beneath and parallel to said beams.

3. In a dinking block support, uprights, longitudinally extensible transverse beams, and a clamp at each end of each beam, said clamp being attached to said beam at a point near the bottoms of said beam and in such manner that said clamp may serve as a hinge on which the associated upright may be turnedabout said point of attachment to a position beneath and parallel to said beam.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
