tion is applicable 'to any plurality of clamps for engaging the side edges or' apiece ot like to mountingthem as one of thet-ransverse series of a-.clamp' carrier .as I have shown. Said clamps may furthermore be of any ordinaryk and lwell-known construction providing atfone end, lwhich is the outer end in fa clampcarrier, ahead 4 with a fixed jaw 5` and providing;l nearer the other end an adjustable jaw 6 adapted to be slid upon side bars `7, 8` by suitable means such as a draw bar S) betweensaid sidefbars and having' apertures 10 to engage said jaw and adapted to be moved longitudinally by a handled nut' `11 upon a screw 12 with which said draw bar 9 terminates at the head of thev clamp. At the other or inner end of the clamp a connection between the side bars 7, 8v, and in the particular clamp shown this connection takes the form of a spanner foot 13 adapted to engage spaced cross-rods 14, 14 such as are mounted at their opposite ends in links of the endless conveyor chains of aclamp carrier (not shown). Pivotally mounted in said spanner foot is a member 15 providing at its forward end a .seat or socket 16 for a removable rod 17 and having at its rear end 18 a spring 19 to normally swing This rod 17 projects forwardly above lthe clamp upon which it, is mountedand is adapted. to be pressed dow-n at its out-er end by the operator and `held parallel. to rthe clamp by a hook 2() uponthe head 4. Such a rod 17 has been used heretofore 'for `carrying,l means lor engaging thin work to hold it. down in place and prevent it springing or bulging' upwardly from the pressure uponvits edges, and to this extent theclamp as thus far described is Well-known and thought to need no further description.
The end-clamps of my invention extend transversely ot the vmain clamps 1, 2 and 3, above the same, and have their bars 21 mounted upon the hold-down rods 17, one end of' each bar carrying an adjustable downwardly projecting aw 22 which can be slid quickly into any desired position, and
at its other end ,a jaw 23 which is adapted to be moved toward the Work by` a screw 24. According to my invention the bars21 of the e11d-01a1nps .extend `beneath `the hold-down rods 17 of the main clamps and are supported thereon so that whenever said hold-down rods are released from their catches 29 and thrown upward by their springs 19 to afford access to the main clamps for putting the worlr therein, the said end-clamps are also carried upward out of the way with said hold-down rods. Preferably the bars 21 of the end-clamps are supported by the holddown rods 17 so as to permit adjust-ment of the end-clamps longitudinally of the holddown rods and also enable the hold-down rods to slide with their main clamps longitudinally of the end-clamps, which I have shown accomplished by slides on the helddown rods each comprising a block 25 havng an upper transverse aperture 26 to re- :eive a hold-down rod 17 and a lower transverse aperture 27 at right angles to the upper one (see Figure 5) to slidably receive an end-clamp bar 21., the block having at its upper part a set screw 28 to clamp it in position upon the hold-down rod. By this arrangement the main clamps are all adjustable with respect to one another to enable them to be moved nearer together or further apart to accommodate different pieces of work, and the end-clamps are similarly adjustable with respect to each other. Furthermore, upon releasing the hooks 2O t-he rods 17 are all swung upward, as shown in Figure 3, and carry with them the end clamps out of the way of the operator in taking out or putting in work. Obviously the end clamps may be mounted upon any suitable means supported at the rear ends of the main clamps so as to swing up and down, other than the hold-down rods shown, and may be made slidable in any suitable way other than by the .slides shown, the particular construction shown being only an illustrative one of many that could be employed.
ln applying the sqnaring means which have shown in the drawings, an outside one of the main clamps, as l, is provided upon the outside edges of its table or work-receiving surface with a longitudinally extending bar 29 riveted or otherwise suitably secured to the clamp with its inside edge formingl a shoulder to engage the work being clamped the jaw 23 of the end-clamps bearing against the opposite edge of the bar. Another bar il() similar to the bar 29 is arranged edgewise against the jaws 5 of the heads t of the main clamps and secured in right angular relation to the bar 29 by being riveted to a corner bracing plate 31 which is also riveted to the outer end of the bar 29 en the clamp 1. This coi-nm: plate 3l is most conveniently placed under the bars 29 and 80, upon the table or work-receiving` surface of the clamp 1, and, to properly level up the rest of said bars for this, a spacing strip 32 is put between the bar 29 and the clamp to which it is riveted, and a spacing strip 33 is riveted to the bottom of the bar 30 to rest upon the tables or work-receiving surfaces of the main clamps 2 and 3, this spacing strip 33 projecting beyond. its bar 30, as at 311-, so that the wort', will lie upon it well :is upon the corner plate 231. For the same reason the adjustable jaws 6 of the main clamps have each an angle 35 riveted by one flange to the face of the jaw so that its other flange lies slidably upon the work table or surface of the clamp and receives the marginal portion of the worlf'; and supports it at the same height as the opposite spacing strip projection 34: and corner plate 31.
It will be understood that the squaring means thus described dees not interfere in any way with sliding of the main clamps 2 and 3 with respect to main clamp 1, the bar 230 and spacing` strip 33 being attached only to clamp 1, through the corner plate 31 and bar 28, and being slidably free from clamps 2 and To retain said bar 30 in place against the worlr tables of the main clamps, their stationary jaws 5 are each provided with an angle 3G riveted by one llange to the face of the aw so that its other flange overlies the bar 30 as a guide, and to retain Said bar '39 cdgewise against thc faces of said stationary jaws of the main clamps the work table of the clamp farthest from the one having the corner plate 31 provided with a guide 87 consisting` of a piece of flat steel similar te that of which. the various spacing strips which have been described are made, said guide beingarranged transversely of the clamp and close to the bar 30 so that the latter cannet move edgewise away from the face of the jaw 5.
lVhile it is very useful in many cases to employ the squaring means with improved end clamps, obviously it is not necessary to do so and the end clamps can be used without any squaring means, in which case the guide 37 and angles 35 and 36 on the jaws are dispensed with. lWhen it is desired to remove the end clamps from the main clamps, as for work in which they are not .neededl` their supporting rods may be removed with them or said supporting rods may remain ou the main clamps to receive the usual pressure shoes (not shown) and serve in the ordinary capacity of hold-down rods. litany other variations may be made in the use of my improvements, and many moditications in the structure of parts and of the clamps to which they are applied, without departing); from the spirit and scope of the invention, and therefore I do not desire to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.
