To all fai/tom t may concern Bc it known that I, DUDLEY S. SEYMOUR, a, citizen ol,l the United States, residing at (')alc Park, in the county of Cook, State of Illinois, have invented certain new and use fnl Improvements in Filled Bag- CSewing 1-\1, pa1:atns, of which the following is a de scription, referencev being had to the accomypanyii'lg,drawing and to the figures of reference marked thereon.

The invention relates to ne7 and useful improvements in devices for sewing illed sacks, and more especially to devices of this character Where the sack is brought by a ccnvcyer to the stitching mechanism, and

also simultaneously fed. past the stitching mechanism with the feed of the sewing ma chine.V

-In devices of this character, it is essential to provide means whereby the conveyer may be driven independently of the stitching mechanism, so that the filled bag may bc placed-on the conveyer and the conveyer started so as to bring the sack to a point ad jacent the stitching mechanism, before the stitching mechanism is set into operation` [n this type of machine, theV operator required to use both hands in properly plac ing the month of the sack so that it may be ied to the stitching mechanism, and there tore, it is also essential to provide a coin trolling device which may be operated by he foot or knee of the operator. so that the conveyor and the stitchin ln'echai'iism may be started and stopped iv ieneve'r desired.

An object of the present invention is to provide a controlling member for 'thc driv? ing devices of the conveyor .and sewing mechanism, which controlling member may be operatml so to control the convfeyer and the stitching mechanisn'i in succession bya single movement of the controlling leven A .further object of the invention, to

provide two independent driving connecn tions for' the sewingI mechanism and `conveyor respectively, iyhich driving connections invlndc separato transmitters and a common controlling mechanism for the two ix'ansmi'tters, which is so constructed that ono transmitter may he operated in advance i oi the other.

Thos-c :und other objects will in part hc ohvions and will in partlie hereinafter more fully (.lcscrihcd.

In Vthc drawings which show by way4 of illustration one embodiment oll the invention;

Figure 1 is an end view ot' a filled sack sewing machine, having my improvements applied thereto, many of the parts being shown more or less diagrammatically;

Fig. 2 is a rear view of the same.Y

In carrying outl the invention, I have provided a `filled sack sewing machine with a driving motor whichY has independent driving connections with two separate transmit ters. Oneof the transmitters is connected to the sewing mechanism and thc other transmitter is suitably. connected tothe con! veyer so that the conveyer and sewing mechanism may be independently controlled and thereby the coni-'ayer caused. to; bring the filled sackv to thestitching mechanism, prior to the operation of the stitching mechanism,

The invention consists'further4 ina single lever which fisconnected with one of ,the transmitters through a yielding device which permits' the controlling lever to more relative to the .transmitter after-the transmitter is closed, for imparting or transmitting a driving motion to the conveyer, and a separate connection,between said controlling lever and the other'transmitter, which connection includes a certain amount of lost motion whereby the eontrollinglever may be moved through a limited distance hotore closing the transmitter.

Referring more in detail tothe dra-wings` the invention vconsists of 'a filled bag sewing machine having e supporting Vtunnel. which is provided with suitable brackets on which is mounted a travelin l eonveyer 2. 'This conveyer, is operated. si` cross-shaft A3,: which carriefs'irgear meshing with a worm 4 on avert'ical, shaft 5. Thisvertical shaft 5, at itsy lower end, 4is provided with a bclt wheel 6. Mounted in suitable brackets ad- -jacent the. belt Wheel 6, are suitable 4belt wheels 7 and 8. These belt. `wheels are mounted to turn about 'un axis at righ-t im.- 100 gies to the axis of thebelt wheel and merely serve sts-guiding wheels to change the direction of movement ofn belt ilwhieh coperaties withV the-belt wheel f5 and also co-l operates with a driven bel-t:` wheelcnr-ried by 105 the transmitter 1l). This transmitter` is` similar in- Vconstruction to that shown andv described in .my prior Patent `No.fh '4,(71 grunted May 21, l9l)7. It will not lic necessary to describe the transmitter in detail, 110

but merely to point out that saidtransmitter includes a driven belt wheel 11 with which the belt 9 cooperates, and a second belt wheel 12, which coperates with a belt 18 which in turnengagesa belt wheel 14 on the shaft of a lsl'ita le motor 15. Said driven wheel of the transmitter is normali held disconnected from the driving whee of the transmitter by a suitable spring, and said transmitter is closed, that-is, the friction surfaces interposed between the driving and driven mem ers, are brought into contact by a swinging lever 16. f

Mounted 'near the upperpart of the frame 1, is a sewing machine 17 which consists of the usual bed plate 18, overhanging arm 19, which carries a needle head in which vibrates a needle 20. Coperating with the needle is the lusual complemental stitch forming mechanism and the usualfeed of the sewing machine. The parte are operated from a driving wheel 21. These parts are of such common use that further description of the stitching mechanism is not thought necessar The drivin wheel of the sewing mac ine is operate by a belt 22 which engages a driven wheel 23 on a transmitter 24. Said belt runs over suitable guide wheels 25, 25. This transmitter 24 is similar in construction to the transmitter 10 and the transmitter is closed by a vlever 26. The transmitter 24 is driven by a belt 24* which coperates with a belt wheel 2lin on the shaft of the motor 15.

The two transmitters are controlled b a.

lever or rock shaft 27 which is provi ed with `an arm 28 and a foot treadle 29, both of which are rigidl attached tov the-shaft 27. A rod 30 is co nected at its` lower end to an eye `31 formed i'n the outer end of the arm 28.' The upper end of the rod is con-v nected with the lower end of a coiled spring 32.. The. upper end of the coiled spring is connected at 33, with tlie'lever 16 which contiolsl the transmitter 10. 'lhe rod 30 as herein shown is made' in twparts which are clamped together by suitab e collars 34 permit the length of the rov 3'0y to be ad- ]usted, so that the position .if the treadle 29 relative to the floorl may be shifted. A rod 36 is connected at its up er end' at 37, with the iev/er 26.5 Said rod a vits lower end is connected at 38 with a collar 39 which and 35." The purpose of thefe collars is to slides freely oli-the rod 30. A fixed collar 40 is clamped to the rod 30 at a point above the normalfpostion of the collar 39.

'lhe operationof my device is as follows: The motor 15 continuously operates the driving pulleys of the two transmitters 1() and 24. 'lhe filled sack is placed on the conveyer. The treadle 29 is depressed Sulliciently to .cl'osethe transmitter 10. Inasmuch as the collar4 40 is spaced above the collar 39, the movement of the .treadle which shifts the rod 30 suiiiciently to close the transmitter 10, will not operate the transmitter 24, but will merely bring the collar l0 into contact with the upper face of the collar 39. This closing oi the :transmitter 10 therefore, causes the conveyer to travel pull 'down the rod 36 and close the trans-- mitter. l

The coiled spring 32 will yield to allow a further movement of the rod 30 after the transmitter 10 is closed, so that the lever 16 cannot be further moved. Upon releasing the treadle slightl the rod 30 will move upwardl through t e action of the spring 32, y

and tie spring controlling the transmitter lever 26 will cause the transmitter 24v to open or release the driven wheel, and the stitching mechanism to stop. A further upwardv movement of the treadle will release the transmitter 10, and cause the conveyer to stop.

From the above description, it will be apparent that I have provided driving connections for the conveyer and stitching mechanism which may be successively controlled fromV a single lever so that the coliveyer mayl be first operated and subsel' quently t e stitching mechanism thrown into action.

While I have shown two independent transmitters, it will be obvious that from certain aspects of the invention, the controlling lever andthe devices intermediate the controlling lever and the transmitters, may be used with other forms of clutch devices than the transmitters, the essential feature being the single lever with the intermediate mechanism whereby the eonveyer may driven independently of the stitching mechanism.

Itis obvious that minor changes inthepdetails of construction and arrangemnt of parts may be made, without departing from -the spirit of the invention, as set. forth in 'appended claims.

devices may be each manually set ,into opera-4 tion in succession. l
