Madison St, Baltimore, Md. 212% Filed Aug. 25, I965, Ser. No. 582,676 (:laims. (Cl. II2I46) ABSTRACT OF THE DISCLOSURE A template for sewing two pieces of material of unequal length, having a lower plate, an intermediate plate hinged to the lower plate for holding the shorter piece of material against the lower plate, a three section upper plate hinged to the lower plate, the end sections of which are flat and adapted to hold the longer of the two pieces against the intermediate plate with the edges of the longer piece of material coincident with the edges of the shorter piece of material and the center section of which is provided with pins for producing puckers in the longer piece of material to take up the excess length of the longer piece over the shorter piece, shaped edges on the lower, intermediate and upper plates forming a guide for sewing the two pieces of material together and pressure devices for holding the plates in clamped position on the two pieces of material.

This invention relates to a template to be used in joining the edges of two pieces of material, particularly where the two pieces of material are of uneven length and the edges are of reversed curvature, and where it is desired to join the edges of material evenly and smoothly, such as the joining of the shoulder seam of front and back coat panels.

In the past the joining of the shoulder seams of panels in a coat has been done by hand and only by skilled workers. In the construction of coats, the back panel of material is longer along the shoulder seams than the front panel in that portion of a coat which is between the collar and the sleeve and the joining of these two panels of material must be such that the finished product must present both an even and smooth finish. The panels are joined so that the ends are matched as to length and the difference in length of the two panels is taken up in the center portion by puckering the back panel adjacent its edge and sewing it to the edge of the shorter front panel so that the difference in length is taken up in small increments to conform to the contour of the shoulder of the wearer.

It is one object of the present invention to provide a template which is semi-automatic in operation and which will position the shoulder seam edges of the two panels so that they can be joined together by sewing in a smooth and even manner by semi-skilled labor.

It is another object of the present invention to provide a template which is formed of a fixed base plate, a hinged intermediate plate, a pair of hinged end plates and a hinged center plate, and so operated that the one panel of material to be joined will be first gripped by the intermediate plate while the end portions of the other panel are in matched position with the end portions of the first panel and the difference in length of the second panel of material will be engaged by the center plate and so arranged as to evenly space the puckered central section through the central area between the end portions.

It is a still further object of the present invention to provide a base plate, a hinged intermediate plate and a hinged upper divided plate, the upper plate being divided into three sections forming independently operated end pairs and an independently operated center plate which cooperate with the base plate and intermediate plate to securely hold the two panels of material of uneven length so that they may be joined, by sewing, in such a manner that the side edges will be evenly matched and the excess material in the longer piece will be taken up in the center of the finished product.

It is a still further object of the present invention to provide a template which will grip and hold the edges of the two panels of material of uneven length and of reversed curved edges so that they may 'be joined by sewing by semi-skilled operators to provide a smooth and even appearance in the finished product, and that the operation of the template in the gripping operation is semi-automatic.

It is a still further object of the present invention to provide power means for operating the movable plates, the upper end plates being separately and individually operable, and after the lateral sides of the two pieces are held in aligned position, the center plate will be operated to so space the excess material in the longer piece that the two pieces of material may be joined to provide a smooth and even appearance.

While several objects of the invention have been pointed out, other objects, uses and advantages will become more apparent as the nature of the invention is more fully disclosed which consists in its novel construction, combination and arrangement of the several parts shown in the accompanying drawings and described in the detailed description to follow. In the drawing:

FIGURE 17 is a sectional view taken on line 1717 of FIGURE 16.

Referring to the drawings and to FIGURES l and 2. in particular, the template is shown supported upon, but not attached to, a support 21 and is made up of a fixed base plate 22 on which an intermediate plate 23 is hingedly mounted by hinges 24. Also hingedly supported on this base plate 22 are a plurality of

upper plates

29, 31 and 32.

A base strip 25 abuts the rear of the hinges 24 and serves as a support for

hinges

26, 27 and 28 which respectively support upper end plate 29, upper center plate 31 and upper end plate 32.

Also carried directly on the base plate 22 is a support 33 carrying a plurality of

operating cylinders

34, 35, 36, 37 and 38. Reciprocating in the respective cylinders, are pistons similar to that shown at 42 in FIGURES 3 and 4 which furnish the mechanical force to operate the intermediate and upper plates to securely clamp the material to be sewed.

The necessary linkage for connecting the plates with the operating pistons comprises

piston rods

45, 46, 47, 48 and 49 connected to their respective pistons and reciprocating therewith. The

piston rods

45 and 46 are connected to

pins

51 and 52 respectively. The pin 51 serves as a pivot pin to connect

levers

53 and 54, while the pin 52 serves in a like manner for the

levers

55 and 56. The lever 53 is pivotally attached to one side of the intermediate plate by upstanding ears 57 and the lever 55 is attached to the other side of the intermediate plate by the upstanding cars 58. The lever 53 is connected to the lever 54 by the pin 51, while the free end of the lever '54 is attached to the base plate 22 by pin 59 and the upstanding ears 61. The two pistons carried in

cylinders

34 and 35 working together to move the intermediate plate 23 on its hinges through an arc sufiicient to insert the material below the intermediate plate and to securely clamp the edge of the material between the base plate 22 and the intermediate hinged plate 23.

A row of upstanding limiting pins 63 secured in the base plate 22 are spaced an equal and definite distance from the guide edge 64 of the base plate 22. The intermediate hinged plate 23 is formed with holes 65 corresponding to the position of these pins so that the intermediate hinged plate in its clamped position will avoid the pins and fall over the pins and closely contact the base plate 22,.The forward edge 66 of the intermediate hinged plate exactly corresponds to the guide edge 64 of the base plate 22, and together with the forward edge 67 of the upper hinged plates forms a guiding edge for the machine stitching.

FIGURE 4 of the drawings shows a cross section taken on the line 44 of FIGURE 1 and this section shows the disposition of the template through one of the end plates when the template is in clamped position, without the material being in the template. The lower and shorter front panel 10 is clamped between the base plate 22 and the intermediate hinged plate 23, while the edge 12 of the longer back panel 12 is superimposed over the lower front panel 10 and is clamped between the intermediate plate 23 and the upper end plate 29. This figure shows the lever connection to the piston where the end plate 29 is provided with upstanding ears 71 to which the lever 72 is pivotally attached. The free end of the lever 72 is pivotally connected to a second lever 73 and to the piston rod 47 by the pin 74. The free end of lever 73 is pivoted to the upstanding ears 75 located on the base plate 22. Movement of the piston 42 from the clamped position (shown in solid lines) to the open position (shown in dotted lines) is illustrated here although it would not normally be included in this view.

FIGURE 3 shows a section taken through the center of the template on line 3-3 of FIGURE 1 and illustrates the structure and working of the upper center plate 31. This plate operates in a manner similar to the end plate 29 through

levers

76 and 77 and the piston rod 48. The upper center plate has an attached reinforcing strip 78 on which are mounted a plurality of parallel horizontally disposed pins 79 (FIGURE 7). These pins 79 have counterparts, carried by the center section of the intermediate plate 23, in pins 81 which are likewise mounted in a reinforcing strip 82 attached to the center portion of the intermediate plate 23. The pins of the strip 82 extend upward from the strip and are then bent to a substantial horizontal position. The pins 79 extend downward from the upper center plate strip 78 and are then bent to a horizontal position, with the pins being so spaced that when the template is in clamped position the pins 79 and the pins 81 alternate and are in substantially the same horizontal plane. Beyond the ends of the pins the upper center plate is formed with a guide edge 83 which when the template is clamped will coincide with the guide edge of the intermediate plate 23 and the base plate 22.

The coat panels are particularly illustrated in FIG- URES 13 to 17.

FIGURE 13 is a plan view of a front panel 10 having a convex edge 11, and FIGURE 14 shows a corresponding back panel 12 having a concave edge 13, and FIG- UR-E 15 shows the diiference in length of these two panels.

Referring in particular to FIGURE 15, the length of the front panel 10 is shown as extending from A to B, and the back panel 12 is shown extending from A to C and it is the difference from B to C in the back panel that must be absorbed into the distance from A to B, that is, the length of the front panel. This is done adjacent the center of the two panels, as best shown in FIGURES 16 and 17. The side edge 11' of the front panel and the side edge 13' of the back panel are aligned, also the side edge 11 and the side edge 13" of the two panels are likewise aligned, and at the same time the

edges

11 and 13 along which the seam is run are brought into alignment as shown in FIGURE 16. This is done at the time the pieces are clamped into the template.

The use of the template is particularly illustrated in FIGURES 8 to 12, and its operation may be described as follows: First, all the movable clamps are raised in open position. The edge 11 of the front panel is placed over the edge of the base plate 22 and in contact with the pins 63 and the intermediate plate 23 is operated to clamp the edge 11 to the base plate 22, as shown in FIG- URE 8. The next step is to place the edge 13 of the back panel over the upper surface of the intermediate plate 23, fitting the back panel over the same lateral distance as the front panel and in contact with the pins 63 and in a manner whereby area 12' of the back panel is opposite area 10' of the front panel, and the area 12" of the back panel is opposite the area 10 of the front panel, and the area 1.. of the back panel is extended over the row of lower pins 81 carried on the upper surface of the intermediate plate. At this point, the two

upper end plates

29 and 32 are first operated to clamp the

side areas

12 and 12" in contact with the upper surface of the intermediate plate and in location over the corresponding

lateral areas

10 and 10 of the front panel. It will be noted at this point that the central upper plate 31 is not in clamping position, and it will also be noted in FIGURE 17 that there is an excess of material shown at 12" in the back panel, and it is this excess material that is gathered in small ripples as shown in dotted lines that is formed by the pins 79 in the upper center surface of the intermediate plate when the upper center plate is moved to clamping position. It is during this movement of the upper central clamping plate that the upper row of pins 79 engage the material in the area 12" of the back panel 12, forcing the material downwardly between the pins 81 to form it into regular increments (shown in FIGURE 10). The spacing of the material is done just before the material is clamped and the clamping action holds the material so that the difference in length of the back panel is gathered regularly and evenly. With the material securely clamped by the template, the template and material pass by the stitching needle adjacent the coinciding edges of the several plates for forming the shoulder seam, after which all the movable clamping plates are released.
