SEXVING-AWL.

Specification of Letters Patent.

Patented July 1 1913.

To all whom it may concern Be it known that I, PAUL PIRNAT, a citizen of the United States, residing at Stone City, in the county of Cherokee, State of Kansas, have invented certain new and useful Improvements in Sewing-Awls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in sewing awls.

The principal object of the invention is to provide an awl which is adapted to support a needle either longitudinally or laterally for respectively sewing harness or the side holder for permitting the thread to be un wound as necessary.

A further ob ect of the invention 1s to provide an awl of thecharacter described in which a tensioning means of novel construction is provided for the spool thereby preventing the spool from unwinding too rapidly. I a

A still further object of theinvention is to provide a sewing awl of the character described which is composed of a minimum number of parts, is therefore simple in construction and is cheap to manufacture.

Vith these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a top plan view of a sewing awl constructed in accordance with my invention, the needle being shown extending longitudinally from the awl, Fig. 2 is a side elevation thereof showing the needle extending laterally from the awl, Fig. 3 is a longitudinal sectional view taken on the line 33 of Fig. 1, Fig. 1 is a detail cross sectional view taken on the line 4-4 of Fig. 1, Fig. 5 is a cross sectional view of the closure plate of the spool holder, and Fig. 6 is a perspective view of the spool.

Like reference numerals designate corresponding parts in all the figures of the drawmg.

Referring to the drawing, the awl comprises a spool holder A, a shank B and a head C.

The holder A comprises a spherical shell 5 having a circular opening 6 formed in its top portion, and a nipple 7 extending laterally from one side thereof, said nipple being bored and communicating with the interior of the shell. Centrally extending upwardly from the bottom of the shell is a post 10. This post extends centrally through and above the opening 6 of said shell and has its projecting end threaded for engagement with a winged nut 11.

A spool12 is formed from metal and comprises a drum 13 and upper and lower flanges 14 and 15. This spool is mounted for rotation upon the post 10, and depending from the lower flange 15 is a circular flange 16. Disposed around the post 10 and seated upon the bottom of the shell is a coil spring 17, the upper end of said spring fitting around the depending flange 16 of the spool. This spring tends to yieldably urge the spool upwardly along the post. Extending upwardly from one edge of the upper flange 14 is a headed finger-piece 18. Arranged within the opening 6 of' the shell and disposed between the upper flange 14: ofthe spool and the nut 11 is a circular closure plate 19, said plate of coursebeing formed with an opening 20 for receiving the post 10.

This plate is formed on its periphery with a notch 21 for engaging the headed fingerpiece 18.

It will thus be observed that by manipulating the nut 11 in either direction, more or less tension can be readily exert-ed upon the spool 12 and consequently the unwinding of the thread from the spool will be more or less retarded.

The shank B is form-ed from an open ended tube, and one end of this shank has threaded engagement with the nipple 7 of the shell 5. The head C is detachably connected to the other end of the shank B, and this head is formed with a longitudinal bore 22, said bore extending entirely through the head and registering with the bore of the shank. Formed in the extreme end of the head and at one side of the bore 22 is a longitudinal seat 23 for receiving a needle 24. A set screw 25 is employed for holding the needle 24: within the seat 23. Centrally formed in the head is a transverse opening 26, and this opening communicates with the bore 22 of said head. Also formed in the head adjacent one end of the opening 26 is a transversely disposed seat 27 for receiving the needle 24. A set screw 28 is employed for holding the needle in the, seat 27.

In practice, the thread 29 is led from the spool 12, through the shank B, and thence through the bore 22 of the head C. If it desired to place the needle in the longitudinal seat 23, the free end of the thread is drawn out through the extreme end of the bore 22 of said head. IVhen, however, it is desired to position the needle 24 in the transverse seat 27, the free end of the thread is drawn out through that end of the transverse opening 26 adjacentthe seat 27. Then the needle is disposed longitudinally of the awl, said awl is ready to be used for sewing harness or shoes on the side. lVhen, however, the needle is extended laterally from the awl, the awl is ready to sew from the inside.

lVhat is claimed is:

1. In a sewing awl, the combination with a spool holder, of a hollow shank extending therefrom, a head extending from the other end of the shank and formed with a bore extending longitudinally throughout its length and communicating with said shank, said head being further formed with a lat eral opening communicating with the longi' tudinal bore, and needle attaching means carried by the head and respectively arranged adjacent the outer ends of the bore and opening.

2. In a sewing awl, the combination with a spool holder including a shell having an Opening formed in its top, a spool rotatably mounted within the shell below the opening tensioning means for regulating the rotation of the spool, a hollow shank extending laterally from the shell and communicating therewith, a head extending from the other end of the shank and formed with a bore extending longitudinally throughout its length and communicating with said shank, said head being further formed with a lateral opening communicating with the longitudinal bore, and needle attaching means carried by the head and respectively arranged adjacent the outer ends of the bore and opening.

3. In a sewing awl, the combination with a spool holder including a shell having an opening formed in its top, a post mounted within the shell and having its upper end threaded and projecting centrally through the opening thereof, a spool rotatably mounted on the post, a coil spring disposed around the post between the bottom of the shell and the spool, a closure plate disposed within the opening of the shell and loosely mounted on the post above the spool, a. winged nut associated with the upper end of the post and engageable with the plate to tension the spring for regulating the rotation of the spool, a hollow shank extending laterally from the shell and communicating therewith, a head extending from the other end of the shank and formed with a bore extending longitudinally throughout its length and communicating with said shank, said head being further formed with a lateral opening communicating with the longitudinal bore, and needle attaching means carried by the head and respectively arranged adjacent the outer ends of the bore and opening.

In testimony whereof, I aiiix my signa ture, in the presence of two witnesses.
