Application filed June 21, 1922. Serial No. 569,979.
To all whom it may concern:
Be it known that I, JEREMIAH F. MARTIN,v
a citizen ofthe United States, and a resident of Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Mountings for Sewing-Machine Heads, of which the following is a full, clear, and exact description.
This invention relates to mountings for sewing machine heads and was primarily designed for use with sewing-machine heads used for sewing filled ba s.
The usual sewing madhine provided for sewing the mouths of filled bags is provided with a massive base that carries the means for supporting thesewing machine head. To install these machines it is necessary to go to some considerable expense in providing a base in the building upon which the sewing machine may be mounted. Such a device is expensive, takes up considerable room, and is very diflicult to move from place to place. The head is usually rigidly attached to the supporting means and when the machine is in operation, if the heavy bag is drawn too quickly through it, the needle breaks thus necessitating the stoppin of the machine to make repairs. The pro lem of eliminating thecost of installation, the expensivebase for supporting the head and the trouble caused by the breaking of the needle by the too rapid movement of the filled bag through the machineis the one which the niventor has solved.
The general object of this invention is the provision of a cheap, simple and eflicient mounting for sewin machine heads that may be easily move from place to place.
A further object of the invention is. the provision of a mounting for a sewing machine head that depends from an overhead support and that is not rigid.
ro- 11(5) a These objects are accomplished b car is adjustably mounted, removably atviding an overhead support upon w taching to the car a guide arm upon which the sewing machine head is slidably mounted and providing in conjunction with the guide arm means for raising and lowering the head.
These and other objects of the invention will be more clearlyunderstood from the following detailed description and accompanying drawings, in whlch,

Figure 1 is a side elevation of the mount '1 ing and sewing machine head;
Figure 2 is a section along the line 22,

Figure 3 Figure 1. I
eterring to the above-mentioned drawings, a track 10 is supported overhead in the building in which the sewing machine is to be used. On this-track is a car assemblage 11 including a, frame 12 and a grooved pulley 13 adapted .to ride'on the track 10. Attached to the bottom of the is a section alongitheline 3 3,
Referring to Figure 1, a sewing machine head 17 of any usualconstruction is shown. In many other machine heads the base 19 of the head has a groove 20 extending across it. With such a mounting this groove is of use and the dependin guide arms 15 is made of such*ashape; an .size that it fits this roove. In this case the sewingmachine head is shown slidably mounted on the guide arm 15 and it .is retained in position on the guide arm by means of a motor 18 which is attached to the head. by bolts21. A-cap 22' is attached to the lower end of-the guide arm 15 by means of a screw 23 and servesas a means for preventing the head 17 from sliding off the :guide arm. If the head is not provided with'a groove in its base then a plate havinga groove might be attached to the base of the head and thus a sewin machine head of any type might be slidab ly mounted on the guide arm.
Attached to the guide arm 15 are bearings 24 in which a shaft 32 is rotatably mounted.
bags 31'. When it is desired to move the sewing machine head from one part of a building to another, by the detaching of the eye 16 from the booklet the head is ready for transportation. When in operatio'n, if the bag 31 is moved too rapidly through the sewing machine thus exerting a pull on the needle, the head will j'swing,
relieving the strain and thus saving the needle from destruction. t
I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I donot limit myself strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the inveiition as defined in the appended claim.
v 5 Claim A swingable sewing machine for sewing filled bags adapted to be suspended by an overhead track and comprising aguide bar, means for supporting the guide bar upon the overhead track and providing for linear 1 movement of the -bar,vmeans for removably connectin the bar with the supporting means and inclu ing means to permit rotation and swinging of the bar, a sewing machine head slidablymounted on the guide bar, means for 1 connecting the sewin machine head to said bar and providing 3 or vertical adjustment of the head on the bar, said sewing machine head being adapted to straddle the unsupported tops of the bags and adapted to be rocked in a pluralityof directions, tdconform to. the movements of the tops o fgthe bags and sup ort the tops of the bags when'said bags at bein sewed I EMIAH-F VMARTINLL
