Int. Cl. D06c 15/00 US. Cl. 223-61 1 Claim ABSTRACT OF THE DISCLOSURE A pin bar which comprises an elongated, straight, fiat bar having along its undersurface at least two rows of pins which can be forced into a porous surfaced table. The bar has on its upper surface, handles to lift and position the bar and is useful in combination with the porous surfaced table in sizing of fabric by providing a portable and removable line up against which the edge of a fabric can be butted to provide a straight alignment of the fabric.

This is a continuation-in-part of Ser. No. 552,348 filed May 23, 1966, now abandoned which is a division of Ser. No. 438,927, filed Mar. 11, 1965, now abandoned.

This invention relates to a pinning device, the general object of the invention being to provide a means whereby draperies, curtains and the like can be easily and quickly placed on a drapery table in a straight line, in preparation for sizing or tabling. The invention also consists in certain other features of construction hereinafter described and illustrated in the accompanying drawings and recited by the claim, in particular to the combination of the pinning device and a porous surfaced work table.

The invention will be described by reference to the figures, of which:

FIGURE 1 is a bottom perspective view of the pinning device;

FIGURE 2 is a top perspective view of the pinning device; and

FIGURE 3 illustrates the work table and the pinning device.

Referring now to FIGURE 1, the pin bar is shown as a generally fiat and elongated member 12 with a plurality of pins that project from its undersurface. As shown in FIGURE 1, the pins are provided in two rows of evenly spaced apart pins. In practice, a suitable spacing of these pins has been two inches; however, this spacing can be varied depending on the firmness of the work table surface and its ability to hold the pins when these are pressed into the table. Preferably, the pins are arranged in sets directly beneath the handles 13 which are used to press the bar and its pins into the table surface. In this manner, adequate locking of the bar to the work table surface can be achieved without the necessity to force the pins into the table surface along the entire length of the bar.

FIGURE 2 shows the top surface of the pin bar with handles 13 provided along the length of the bar; at least two handles are provided although more than two can be provided at spaced intervals for lengthy bars. The handles provide gripping surfaces for the users to pick the bar up from the table and to force the bar and pins into the table surface. The pin bar is formed of wood or metal construction with a length to thickness ratio of from about 250:1 to about 10:1 and with a width adequate to prevent flexing of the bar in a plane perpendicular to its bottom surface, thereby providing an accurate and straight line up on the table surface. Typically, the bar is provided with a width which is at least equal to and preferably from 1.5 to 5 times its thickness to insure rigidity in the plane perpendicular to its undersurface. In an embodiment that has found acceptance, the bar is one inch thick by two and one half inches wide and as long as is required, e.g., 60 inches. The bar can be made any length with the same width and thickness as required by the work table size or the size of the fabric to be tabled.

FIGURE 3 illustrates the combination of the pin bar 12 resting on table 20 with pins 10 of the bar forced into the porous surfaced work table. Typically the table is covered with a canvas surface over a porous underlay such as felt or cork. The fabric to be sized or tabled is placed next to the bar 12 and is thereby placed in a straight alignment on the surface of work table 20. When the fabric is in this position, the fabric securing device of my copending application, now Patent 3,386,728 which comprises a bar of similar size and shape and which has several rows of pins along its length and protruding from its undersurface, is placed over the fabric 24 and is forced into the table with its pins penetrating fabric 24 and the porous surfaced work table. In this manner, the fabric is rapidly aligned and secured to the table.

The pin bar 12 rests on the table with its pins 10 penetrating the porous surface directly without penetrating any other porous materials such as fabric 24. In this use the pin bar 12 is freely detachable and removable from the table so that after alignment of the fabric the entire work table surface can be unobstructed. The bar can also be located at any place on the table to accommodate any size of fabric. The pin bar is placed at the desired measurement on the drapery table and a downward push on each of the handles secures the device in place so that the fabric to be tabled or sized may be placed next to or butted against it in a straight line. Being light in Weight and freely removable from the table it is easily handled and quickly placed in any position on the drapery table.

While the invention has been described with reference to a particular illustrated device, it is apparent that other equivalent devices can be employed such as bars of ribbed or open webbed construction, etc. It is intended that the invention be defined by the means, and their equivalents, set forth in the following claim.

I claim:

1. The method for tabling a fabric to be sized that comprises positioning on the top of a work table having a porous surface and near an edge of said table an alignment bar comprising an elongated bar rigid in a plane perpendicular to its undersurface and bearing a plurality of pins protruding from its undersurface; pressing said bar against said table to force said pins into the porous surface of said table to thereby secure said bar on said table surface; placing the fabric on said table; butting an edge of said fabric against the inboard edge of said bar; placing a second elongated bar bearing several rows of pins along its undersurface in juxtaposition to said alignment bar and forcing the pins of said second bar through 3 4 said fabric and into the porous surface; and removing 3,285,480 2/1961 Estephanian 223-61 said alignment bar from said table. 3,386,728 6/ 1968 Smakel 269----289 References Cited PATRICK D.
