ATTORNE Patented Sept. 12, 1939 UNITED STATES PATENT orries AUTOMATIG PIN SETTING DEVICE FOR HOLDING MATERIALS FOR SEWING This invention relates to new and useful immovements in a device for holding materials for sewing, particularly, tie material.

More specifically, the invention provides for a plurality of pin setting devices attached to a table and which are adapted to insert pins into aligned sections of tie material for holding these materials in their aligned positions so that they may be sewn by hand or upon a conventional sewing machine, after which the pins may be removed.

Another object of the invention is the construction of a pin setting device in the normal position of which the device swings away from the top of the table permitting the top to be free from any interfering members so that the operator of the machine may easily align the pieces of material into which it is desired to insert the pins.

Still further it is proposed to provide a novel type of pin holder which is adapted to grasp one of the ends of the pin to hold it in a horizontal position so that it may be moved laterally for inserting the pins into the cloth.

Another object of the invention is to provide a construction in which a continuous roll of wire may be substituted for separate pins and which may be cut into small sections for insertion into the aligned materials.

Another object of the invention is to so construct the pin inserting devices that they may be out of their normal aligned positions so that they may be used for inserting pins into curved seams.

Still further it is proposed tointroduce a new and novel device for reversing neckties and which consists of a spiral shaped spring attached to a flat member and which is adapted to be inserted into the small end of the tie for positioning the I tie upon the fiat member so that the wide end of the tie may be passed over the narrow end.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 13 is an enlarged View of one of the pins used in this device.

The automatic pin setting device for holding materials for sewing consists of a table It having a guide gauge ll mounted thereon and against which a lining l2 and covering material I3 of a tie may be positioned. Holding strips I4 are engageable over the lining and covering materials for holding the materials in position while the covering material I3 is being folded upon itself.

A plate 15 is slidably mounted on the top of the table ill and has one of its edges l5 engaging beneath a portion of the covering material l3 so as to fold the covering material over the holding strips when the plate [5 is manually moved rearwards. A manually operable means for inserting pins into the material at spaced positions for holding the materials in their folded positions is pivotally mounted on the table, as will be hereinafter set forth.

The table consists of a table top having a substantially flat surface and provided with a resilient covering Mi upon which the lining and covering materials may be positioned. It has legs 5t for supporting the table [0 at a position in which it is convenient for the operator to align the materials and also operate the pin setting device. The holding strips l4 consists of end sections M which are pivotally mounted on the ends of the table l0 by means of hinges l6 and are provided with extending portions M extending at'right angles to the end section M and have their ends abutting each other at about the center of the table top H]. With this arrangement it is possible to pivotally raise the holding strips l4 after the pins have been inserted into the covering material l3 to withdraw the tie from the strips. Inasmuch as the tie material is obviously flexible, this step is accomplished by simply grasping the central portion of the tie and slidably raising it off the strips H.

The holding plate |5 comprises a piece of substantially flat material provided with an upturned edge l5 by which the plate may be grasped for manually moving it rearwards. The table top I0 is provided with elongated slots through which pins I8 from the plate l5 project and which act to guide the plate l5 in its forward and rearward movement for properly folding the covering material l3 over the holding strips l4.

The means for inserting the pins into the material consist of a plurality of separate devices connected together for simultaneous operation, and each of these devices consists of a bracket l9 which is pivotally mounted by means of a stud 20 upon a lug 2| extending from the face of a plate 22 which is attached at the rear of the table H]. A member 23 is pivotally mounted inter- 'mediate of its ends on the bracket l9 by means of a stud 24 and has one of its ends 23 extending over the table I. A resilient means consisting of a spring 25 extends between a screw 26 engaging through a portion of the bracket l9 and an eye member 21 attached to the underside of the member 23. A rod 28 is slidably mounted through the other end 23 of the member 23. A stop pin 29 is fixedly attached to a portion of the plate 22 above the pivot point of the bracket |9 for limiting the turning of this bracket. Means are provided for moving the rod 28 to turn the bracket l9 until it strikes the stop 29 to limit its pivoting so asto pivot the member 23 on the bracket l9 against the action of the resilient spring 25 until the bottom of the member 23 strikes against the aligned materials positioned upon the top of 'the table I0.

Pins 39 are contained withina pin supply 3| in the end '23 of the member 23 and a pin holder 32 is mounted on the member 23 and has opposed holding jaws 32 for receiving and holding the end of one of the'pins 30. Means areprovided for moving the pins downwards from the pin the pins laterally, operable only after the member andthe "bracket have ceased pivoting, as will be seen, for forcing the pins into the tie materials for holding the materials in their aligned positions. The pins are pointed at each end and, in a preferred form, are provided with annular rooves 30') at each end (Figure 13) to interrupt the'smooth surface'of the pin, and thus better insure that the pins will stay in the fabrics until they are ready to be pulled out.

The bracket i9 has lug portions l9 by which it is pivotally mounted on the lugs 2| of the plate 22 and other lug portions l9 upon which the member 23 is pivotally. mounted. An extended portion IQ of the bracket |9 is provided with a threaded opening through which the screw 26 may be passed and against which the member 23, strikes when the spring 25 draws these two members together. This screw 26 may be adjusted to control the relative positions of the member 23 and the bracket IQ for controlling the distance through which the member 23 will move with relation to the bracket IS.

The means for moving the rod 28 to 'pivot the bracket l9 and the member 23 consists of a shaft 33 which is rotatively mounted in brackets 34 tached to the shaft 33 and a link 35 has its ends pivotally attached to the other end of the radial arm 34 and the lower end of the rod 28 for pivoting the bracket l9 and the member 23. A foot pedal'36 is fixedly attached to the shaft 33 and extends to the front of the table It] and is provided with an enlarged portion 36 upon which ones foot may be placed for pressing the foot pedal 36 downward to turn the shaft 33, which in turn raises the radial arms 34 upwards (see dot and dash line 34 in Fig. 5) to cause the link 35 to act against the bottom end of the rod 28 to pivot the bracket I9 until it strikes the stop 29 for limiting the pivoting of this bracket and.

the smaller opening and another opening 3| connects the smaller opening with the slot 31. The purpose of having the two openings connected by the narrow slot, which in turn is connected by another narrow slot with the slot 31, is to prevent the pins from jamming on the top of the'jaws 32 and for limiting the passage of these pins. It will be noted that the pins will come out upon the top of the jaws 32 in a single file after each downward motion of a plate 38 which is'slidably mounted within the slot 31.

This plate 38 is fixedly attached to a member 39 which has its top end pivotally connected with a lever 40 which is pivotally mounted intermediate of its ends upon a lug 4| formed upon the member 23vand a stud 42 is passed through these parts to accomplish the pivotal mounting. A rod 43 is slidably mounted within the member 23 and has its ends extending from the top and bottom of the member 23. The top end of the rod 43 is provided with a cam 44 adjustably mounted thereon and which engages a complementary cam recess 45 formed on' the adjacent end of the lever 40 for pivoting the lever 40 as the rod 43 moves up and down to. cause the plate 38 to move similarly. The cam is mounted upon the end of the rod 43 by means of opposed nuts 46 which threadedly engage this extended end and which may be adjusted to change the position of the cam 44 with relation to the rod 43 to control the distance through which the lever 40 will pivot when the rod 43 moves up and down.

' The other end'of the rod 43 is provided with a ball bearing 41 which is adapted to engage a portion of the bracket I9, and when the member 23 pivots on the bracket IS the ball bearing will ride on the bracket and cause the lever 43 to be urged upwards, which in turn will pivot the rod 40 causing the plate 38 to move downwards V forcing the pin downward between the jaws 32 of the pin holder to a position in which it may be easily passed into the tie material.

Plugs 48 are engaged into the ends of the opening in the member 23 through which the rod 43 passes, and the rod 43 is provided with a shoulder 49 intermediate of its ends. between one of the plugs 48 and the shoulder 49 to urge the rod 43 downwards to a position in which the ball bearing 41 will bear against the bracket l9. A spring 5| is mounted within an A spring 50 operates enlarged portion 3'! of the slot 31 and operates between the bottom of this enlarged portion and a pin 52 extending from the plate 38 and tends to normally push the plate 38 upward within the groove 31. Thus it will be seen that the action of the springs 58 and 5| will tend to cause the members of the pin moving device into a position in which the slightest movement of the member 23 on the bracket l9 after this bracket has ceased to pivot, will cause these members to operate forcing the pins 38 downward between the jaws 32 of the pin holder 32. This pin holder 32 consists of jaw portions 32 one of which continues into a portion 32* extending upward at an angle to the jaws 32 The portion 32 continues into another portion 32 which extends upward at an angle from the portion 32 and which is parallel with the jaws 32 This pin holder 32 is mounted within a cavity 23 and the portion 32 is provided with an elongated slot 53 through which a screw 58 may be passed. The screw 54 threadedly engages into the'end 23 of the member 23 and is adapted to hold the pin holder 32 in various adjusted positions upon the member 23 to control the positioning of the pins 3| with relation to the material in which the pins are to be inserted.

The top face of the table l8 has a cam 55 which engages a complementary cam recess 56 formed in the bottom face of the member 23. This cam is adapted to force the material into a curved position at the end of the pin 38 which is held between the jaws 32 of the pin holder 32 so that when the pin 38 is moved laterally, it will be forced through the curved portions of the materials. The means for moving the pins laterally consists of a member 5! which engages the free end of the pin 38 and which is adapted to move laterally for correspondingly moving the pin laterally. This member 5'! has an upwardly extending stud 58. Alever 56 is pivotally mounted upon the bottom face of the member 23 and has a slot 68 into which the stud 58 engages for moving the member 51.

A bell crank 6| is pivotally mounted intermediate of its ends by means of a pin 62 and has one of its ends provided with a reduced portion 63 which engages an opening 64 in the lever 59 for pivoting the lever when the bell crank is moved. The other end of the bell crank 65 is engaged over the upper end of the rod 28 and is positioned within a tensioning device for holding the bell crank 6| in its normal position as shown in full lines in Fig. 6. This tensioning device consists of a collar 65 fixedly attached to the rod 28 by means of a pin 66 and opposed conical shaped members 61 are mounted upon the rod 28. A spring 68 is coaxially mounted on the rod 28 and operates between the lower conical shaped member 61' and the collar 65 for urging the conical members 61 together. The end of the bell crank 6| has an elongated slot 59 which engages over the upper end of the rod 28 and between the conical members 61. The top of the rod 38 is provided with nuts 18 which bear against the topmost conical member 61 and which may be adjusted with relation to the rod 28 for increasing or decreasing the tension with which the spring 28 will bear against the lowermost conical member 61.

A spring ll having a tension greater than the spring 25 is mounted on the lower end of the rod 28 and operates between the bottom face of the member 23 and an enlarged portion of the rod 28 for preventing this rod from moving upwards with relation to the member 23 for preventing the bell crank from being pivoted until the bracket 19 and. the member 23 have ceased pivoting. After these members have ceased pivoting it is still possible to depress the foot lever 36 to urge the rod 28 upward to pivot the bell crank 6|, which in turn pivots the lever 59 and which in turn causes the member 51 to move laterally for correspondingly moving the pin 38 to engage the pin into the portions of the material which have been foldled over the cam 55. As shown in Fig. 2 there are a plurality of these pin setting devices which are connected together by means of a bar 12 attached to the bottom faces of the members 23 for causing these devices to move simultaneously when the foot pedal 36 is depressed.

The operation of the device is as follows:

Assuming that the parts are in their normal positions, shown by the full lines in Fig. 5, a plurality of pins 38 are put into the pin supply 3| formed at the front end of the member 23, and the lining and covering materials are placed in their aligned positions on top of the table I8 with relation to the guide H. The plate 15 is moved rearwards to cause the front edge of the covering material l3 to be folded over the holding strips M which have been positioned upon the aligned materials and the foot pedal 36 is depressed causing the bracket [9 to pivot until it strikes the stop pin 29 (see dot and dash lines in Fig. 5). The member 23 pivots on the bracket l9 until it strikes the top of the cloth materials which have been positioned on the table I8 (see full lines in Fig. 6). During the time that the bracket 19 ceased pivoting and while the member 23 is pivoting, the rod 43 is being urged upwards to cause the lever 48 to be pivoted to force the plate 38 downwards against the holding action of the spring 58 to press the lowermost pin at the end of the passage 3| down on the pin holder 32 until one of its ends engages between the jaws 32 and the other of its ends rests on the member 51. After the member 23 has ceased pivoting the foot pedal 36 is further depressed to cause the rod 28 to move upward with relation to the bracket 23 and the holding action of the spring H to pivot the bell crank 6|, which in turn pivots the lever 59, which in turn moves the member 5'! laterally to move the pin 38 laterally to engage the positioned pin into the materials which have been bent over the cam 55 by the cam recess 56 formed in the bottom face of the member 23.

When the foot pedal 36 has been depressed as far as it will go the pin setting operation has been completed and the foot pedal 36 should be released to permit the springs 25, 58 and H to draw the member 23, the rod 43 and the rod 28 back to their original positions, which is shown by the full lines in Fig. 5, and the dot and'dash lines in Fig. 1. The next operation is to remove the materials l2 and I3 from the table top I 8 and this is accomplished by withdrawing the pin-secured tie material from the holding strips, as aforesaid, to permit the materials to be sewed upon a conventional sewing machine, after which the pins may be removed, or by hand, in which case the pins are removed while sewing.
