Nov. 25, 1952 A. A. WEINGARTN ER BUTTONHOLE SPACER Filed June 1, 1950 1 N V EN TOR. AaazzzA. M elkgarzer B Y ATTORNEY Patented Nov. 25, 1952 UNITED STATES PATENT OFFICE Myinvention relates. generally'to buttonhole.

spacers and specifically to buttonhole spacers which, with a single-setting, will determine a plurality of spacings.

It is among the objects of my invention to provide: for" the accurate placement. of buttonholes .on. items wherein: a plurality of; successive holes are to bemadeand spaced equidistant from each other.

It isa further object 'of my invention to provide a means for quickly'determining theposition of a. plurality" of buttonholes comprising. a series.

It is'yet .a further object of my invention to providean adjustable variable means'forplacing a variable number of equally spaced buttons in relationship corresponding to the size of the garment to which they areattached.

It is among the further objects of my invention to provide a buttonhole spacer that is simple inform, easy to use, relatively inexpensivaand durable.

These objects and advantages, may beachieved by the device illustrated in the drawings, in which:

Figure-1 is a. top view showing the buttonhole spacer disposed in operable relationship to a buttonhole machine, and'an item symbolical of a garment to" which buttonholes are to be applied; and

FigureZ is a side view of the buttonhole spacer.

Referring. now to the drawings in detail, my buttonhole spacer has a bar or support II which serves as a mounting for theseveral indicators or positioning means. This support II is attached to the machine table l2 by a. bracket l3- atone end, and. another bracket 14 atan intermediate point. Mounted on the support ll, there is an index 15. This index. is attached to thesupport H. by a pivot. pinlfi. One end of. the index l5 has a down-turned endor' pointer IT. The other end, beyond the pivot pin I6 has an extended portion [8. This extended portion 18 has a plurality of holes l9 disposed in a series.

At the opposite end of the support ll, there is another. index 20. This index 20 is also attached to the support H by a pivot pin 2|. The tip of the index 20 is provided. with a point 22 so that it may be precisely lined up with a point on a garment. Between the point 22 and". the pivot pin 2|, there is another pivot pin 23 mounted on the index 20 which serves as. a mounting tor a connector 2d. The connector 24 isia'rod or bar which isattachedi at one end as aforesaid, and at the other end, is attached to the index l5 by a pivot pin 25 inserted in one of the holes IS. The pivot pin 23 is threaded so that it will engage the threads in the hole which it enters in the index 20. By tightening the pivot pin 23, the. index 20 may be locked at any chosen position. Adjacent to the point where the pivot pin 23' attaches the connector 24 to the index 20, there is a series of holes 26 in the connector" 24. These holes 26 enable the bar to be adjusted to: accommodate garments of varying sizes beyond the ordinary range of adjustment. The holes: 19 on the other hand, are positioned so as to increase or decrease the ratio of movement of the indexes when they are moved with respect to each other. Thus, one of the holes [9 may be the setting by which an operator can gauge the position of the successive buttonholes in a series of 8, while the. next hole will gauge the position of successive buttonholes in a series of 7, et cetera.

Now for the manner of use and operation of my buttonhole spacer, the operator makes the first buttonhole 21 in the garment which is symbolically illustrated by the buttonhole strip 28. The strip is then moved on the table and the: indexes are adjusted so that the index 22 coincides with the point where it is'desired that the. last buttonhole shall fall, and the pointer II lies over thefirst buttonhole 21 as shown in Figure l. The second buttonhole 29 will then fall at the point of the needle 39. To keepthe pointer 11 asa gauge point for successive buttonholes, the pivot pin 23, which is in reality also a set screw, is tightened. Thus having completed the'second buttonhole 29, that buttonhole 29 is moved into coincidence with the pointer l1 and the correct position for the next buttonhole will automatically lie under the needle 30. This is brought about because the distance from the needle 30 to the point 22 is always the same multiple of the distance from the needle 30 to the pointer I! regardless of where the point I! is movedv to. Depending on the hole l9 selected, distance- 32 will, for example, if six buttonholes are to be made, always be four times greater than distance. 3!. And if for example, sevenbuttonholes are to be made, the connector 24 is. ad.- vanced from the six buttonhole hole [9, to the next hole 19 which is the "seven buttonhole hole. Automatically, the distance 32 delineated by the point 22 and the needle 39 will be live times the distance 3| measured by the. pointer IT and the needle 30.

The operator then continues to move each buttonhole when completed to the pointer 11 and the correct position of the next buttonhole will fall at the needle. This operation is continueduntil the requisite number of buttonholes in. the series has been made.

The foregoing. description is intended merely as illustrative of one embodiment of my invention, for many changes in the construction,
