Description
UNITED STATESy PATENT OFFICE.
JAMES T. SIVAIN, OF PITTSBURG, PENNSYLVANIA.
BOLTING OR CLAIVLPING DEVICE.
SPECIFICATION forming part of Letters Patent No. 559,506, dated May 5, 1896.
A Application filed January 22,1396. semi No. 576,423. er@ model.)
To all whom it may concern:
Be it known that I, JAMES T. SWAIN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented an Improvement in a Bolting or Clamping Device; and I do declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication.
My invention relates to an improvement in a bolting or clamping device to be used on a faceplate or platen, as shown in the accompanying drawings, in which;
Figure l is an end view of the device; Fig. 2 a side View, and Fig. 3 a perspective view, of a section of a table, inwhich the device is shown in position ready for use.
Similar letters refer to similar parts throughout the several views.
The pieces A and B constitute the device. The bolt C shows a bolt in position ready for use. The device is put in position by dropping one part, either A or B, in the slot, and then dropping the other part in at the end of the first one and sliding it beside the other, as shown in cuts. The two pieces A and B are in every way alike, and are interchange able. In my device I claim a great improve ment over all otherways of bolting or clamping. i
The following are a few of the advantages of my invention. When used on a planer, the slots in the table do not have to be cleaned out, except the lengths of the pieces, and even that can almost be done with them. If a bolt breaks, another can easily be put in instead. The work can be laid on the table before the bolts are set, thereby saving time in measuring bolts. In case, after the work is set on the table, it is found that the bolts are in the Wrong place, or that they are either too long or too short, or that it would be better to clamp on some other part of the work, or that VVthe bolts do not hold sufficiently, they can be and changed to the outside when :finishing the inside. In putting on or taking the work off the table can be clear. The cross-head does not have to be raised to get the work over bolts.
I am aware that by the use of T-head bolts some of these difficulties are overcome; but as I have before stated they break the corners off the inside of the slots and in time spoil the table, and also the bolt-heads have to be thin and narrow, and the bolts sometimes turn while being loosened and the work when overhanging the table is liable to fall off.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is
An improvement in a bolting or clamping device, consisting of two symmetrical partsA and B, each being provided witha half-T-slot for receiving the head of a bolt and a half-T- shank, adapted to slide in the T-slot of a faceplate or platen, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES T. SWAIN. Witnesses: MARY M. HEDDEN, DENIS M. BEHEN,
