Thisv inventiony relates totables for cutting cloth and is herein illustrated in some detailas'embodied in a table'havingv attachments for holdinglayers o f folded cloth in such` form that the attachments may be readily Withdrawn after the folds of cloth have been suitably laid on the table thus leaving a smooth,v uninterrupted surface on which thecloth lies ready'for cutting. V

Hitherto it has been the custom-in many shops Where cloth is to be cut, to drive in sharppointed nails in the table, and to lay the cloth in folds on the table face by stretching a length over one set of the projecting nail fronts, carrying the bight of the cloth back to an opposite set ofy nailpoints; impaling it on them, carrying the bght of the restof the cloth back over the first set of nail points, and so on.

The driving. of nails in different parts'of the table damaged much `of its surface, eventually destroying the surface ofthe table and was timeconsurning.

Endeavors have been-made to provide tables with cross bars to which pins` were boltedn and the cross bars were held'by screw clamps at opposite edgesofthe table, but these proved cumbersome and failed of adoption. Itl has also been proposed to mount impaling 4pins on a rotatable rod lying Within a groove in the tabletop, so

that rotation of the rod could carry the pins down into individual grooves extending at right angles, to the rod groove, thus getting them out of the Way, but this structure involved other difficulties in breaking up the smooth table top' so that it interfered with satisfactory cloth cutting, 'and in getting the pins out of the cloth to turn theminto the grooves.

In the form of the invention herein illustrated the foregoing and' other diiiiculties and objections are overcome, and the cutting table is provided' With an equipment of pins Which firmly holdthe cloth during cutting, is provided with pins which are readily removable and yet. are quickly and accurately set as to rmly hold the cloth, and, moreover, the table top provides a smooth surface for the subsequent cutting operation.

In the form shown the device is provided With removable pins which may be clamped so as to project above the surfaceof the table for holding the cloth but which are readily removed after' the cloth has been satisfactorily laid.

In the form shown the pins atA one end of the cutting table are settable along an adjustable edge thus enabling the table to be readily' and 55 efficiently-used for laying clothvin folded lengths of any desired length.`

The table l Gis shown with avrectangular plank top II- and legs 12 near the corners.

In the form shown, ther table is adapted to firmly but releasably hold a set of vertical pins or spikes-'near one end f I3,A and to rmly but releasably hold' a second set of pinsv or spikes along an adjustable bar Ill1 which may-be set near the opposite endl I5v of the table I0:

Inthe form showna bar i6 held to the end l^3`of the. table by screwsl l1 is notched at I8 to receivetheshanksl |9-of a pin 20so that the pin shank I9 is firm-ly clamped in the notch IB and a facing notch 2| in a clamping bar 22-which extendsV along the full length of the Lbar |6that is to say, the full width of the table I0.

In 'the form shown'six pairs of pin notches I8" and 2i are adapted to hold six pins 20, and the pins are rmly held because the clamping bar 22 is adapted to slide over a small shelf 2'3 projectingfrom the bottom of the bar I6' and to be drawn tov/ardthebar' l'by turning bolts 24 whichare threaded. at 25 where they pass through the metal face4 2liy of the clamping bar 2i2.thus.drawng the bar down by the enlarged bol'ti heads 21Y which turn in pocketsy 28 behind the notchedbar I6.v The heads 2,1 maybe lock nuts put on after the bolt is passed through the bar I6 and beforethe bar'l'is putin place.

Thus, when a pin or series of pins 2li are" leased. The number of' bolts may Avary with the Width of the table I0, and the number of pins 20 and pin notches I8 and 2| will vary with the width of the table I0.

The clamping bar 22 is shown as extending beyond the metal bar 26 to provide a flat extension of the table to enable the turns in the folds of cloth to be evenly supported.

For holding the opposite ends of the folds of cloth there is shown a slidable cross bar I4, lying on the surface of the table I and provided with a depending lugr 3I near its end 32 extends beyond the table edge at 3i), so that the lug seats itself in any one of a number of spaced openings 33 in a side bar 34 held by screws 35 and holds its end of the cross bar I4 against sliding.

To give desired support to the opposite end 37 of the cross bar I4, and yet leave the edge 36 of the table clear so that it can be slid up against a second table for very Wide cloth, the end 31 is shown provided with a seat 38 adapted to receive and hold against thrust the horizontal end peg 39 on a brace 40. The brace 40 is shown as lying diagonally on the face of the table ID and carrying a depending peg 4I at its end 42, so

that peg 4I may seat itself in an opening 33 and thus hold the brace 40 to hold the cross bar I4 firmly. v

The cross bar I4 is shown as provided with vertical notches 43 which cooperate with notches 44 on a second clamping bar 45 to hold pins 20 which may be identical with the pins 20 set in the notches I8 and 2 I.

The pins 2U may be set up in the notches 43 and 44 when the clamping bar 45 has been released, and then rest upon the top of the table y I0. They may be firmly clamped in place by screwing up bolts 46 having Shanks 41 threaded where they pass through the clamping bar'45 and headed over at 48 at the front of the cross bar I4 so that screwing the bolts 46 draws the clamping bar 45 against the cross bar I4 to hold the pins 26 in the notches 43 and 44.

The heads 48 may be covered with small hoods 49 held by screws 50 to hold them in position when the clamping bars are opened.

To prevent accidental impaling of an operators hands, or of goods, on the pins 2U in the notches 43 and 44, and to prevent catching the cloth when it is desired to roll the still-rolled cloth over the pins, the pins may be covered by a removable protecting bar I shown in the form of a bent-over flange on plate 52 which is hinged. at 53 along the back upper edge 54 of the clamping bar 45. When the plate 52 is swung upwards and against the top of the pins its flange 5I overlies the points 55 of the pins 20 to cover them, but is easily swung down and back out of the Way to lie flat as an extension of the clamping bar 45.

The pins 20 shown in Figs. 2, 3 and 4 are easily pulled up out of the fabric after loosening the clamping bars 22 and 45 to release the pins 26 in the notches 43, 44. Then the clamping bar 45 and the cross bar I4 may be removed by sliding them out as a unit and the brace may be removed by sliding it out, without danger of shifting the cloth.

The pins 20 in the notches I8 and 2| are usually removed before cutting the cloth. They are removed by releasing the clamping bar 22 to release the pins.

Sometimes it is preferable to use the alternative form of pin 58, shown in Fig. 5, which has the same shape of shank I9, but is provided with an enlarged spear-shaped head 5l which tends to retain the cloth impaled upon it, but allows the pin 56 to be readily withdrawn through the cloth impaled upon it.

When the cross bar I4 with its clamping bar and brace 40 is withdrawn from beneath the folded cloth, and the pins 20 have been withdrawn from their notches I8 and 2I, and the clamping bar has been re-clamped against the end bar I6, the table presents an almost perfectly smooth surface on which the cloth may lieand against which it may be pressed by the usual weighteddown cutting pattern, not shown. Thus the cloth I is uniformly held to be cut by the usual power cutter, or by a hand cutter, as the ease may be.

Figure 6, shows how a special form of pin 5l may be used to overcome some of the difficulties which arise in laying many layers of cloth on a cutting table. That difficulty arises from the fact that each layer of cloth impaled upon a row of pins puts increased tension upon the rows of pins tending to bend the pins toward the center of the table thus altering tensions as the pins bend.

In order to overcome that diiiiculty there may be provided the special pins 56 having round shanks 58 adapted to fit in a series of half-round matched notches 53 in the cross bar I4 and second clamping bar and in the table end I3 and its clamping bar 22.

The pins 56 are adapted to be set up after a number of folds of cloth 64 have been impaled on set up pins 20. To enable the pins 56 to be thus set up without lifting the folded cloth from the pins 20, each pin 51 includes an off-set portion 60 above the horizontal reach 6 I In the form shown the horizontal reach 6I lies close against the top of the clamping bar 45. Each pin 56 also includes a top impaling length 62 beginning about the height of the top of points 55 of the pins 2li, and high enough to hold the desired further folds of cloth like the folds 64.

The length 62 is connected by an upper reach 63 with the offset portion BD, with the result that the pins 56' can be inserted in their notches 59 by partly lifting the folds 64, placing the Shanks i 58 in the notches 59, dropping the cloth folds into the opening found by offset 60, and then laying more layers of cloth and impaling them on the pins 5l at each end of the table.

While the half round recesses fitting loosely about the lower ends of the pins 55 cooperate with the cloth to hold the pins in position, a strip of metal 6l may be inserted between the ends of the layers of cloth and the offset portion 60 as shown in Figs. 6 and 'l to cooperate also in holding the pins in position. The strip of metal 6l may have vertical grooves 68 adapted to register with the offset portion 60 of the pins 56'. While rounded recesses 59 are shown in Fig. l for holding the lower ends of the pins, they may be omitted and the ends of the pins inserted loosely in the spaces between the clamping bar intermediate the regular pins 5S.

As various changes may be made in the form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpretedas illustrative and not in a limiting sense.
