Original application filed December 8, 1919, Serial No. 343,391. Divided and. this application filed June Z '0 all @071 am it may concern:

Be it known that I, EDWARD GUY GoBnN, citizen of the United States, and resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in an Adjustable Feeding Apparatus, of which the following is a specification.

This invention relates to an adjustable feeding ap aratus and is a division of my patent app ication for cutting machine for cloth and other material filed December 8, 1919, Serial Number 343,391. Its object is the production of such an apparatus whereby sheets of cloth'or other material can be fed therethrough, and in which the amount of material fed can be manually varied or stopped at the will of the operator.

A second object of the apparatus is the production of means, whereby the material fed therethrough can be observed by the operator. The amount of such material operated upon depends somewhat on its thickness, smoothness of surface and consistency, requiring manual means to control its speed through the apparatus.

In the accompanying drawings Fig. 1 represents a side elevation of an exemplification of an adjustable feeding apparatus with a fragmentary portion of a cutting machine with which it is adapted to operate; Fig. 2 shows a top plan view of Fig. 1 and Fig. 3 is a section of Fig. 1 on the line 3, 3.

A frame of the feeding apparatus is indicated with the pair of channel iron col uinns 20 and the pair of circular columns21, the upper ends of the latter being flattened at 22* A pair of channel irons 23 connect the upper ends of the columns 20 and 21, and pairs of angle irons 24 and 25 also connect the said columns, One of each pair of the angle irons 2 1 and 25 is below and in line with one of the channel irons 23, and the other angle irons 24 and 25 of each pair are below and in line with the other channel iron A pair of angle irons 26 is connected to the lower faces of the channel irons Angle irons 27 are connected to the upper faces of the angle irons 2a and are in line with the angle irons 26. Angle irons :28 are connected to the upper faces of the angle irons 25 and are in line with the angle irons 27. A pair of angle irons Serial No. 174,863.

29 are also fastened to the upper faces of the angle irons 25. A. pair of journal bearings 30 are located. upon and fastened to the angle irons 24. A shaft 31 is journaled in the journal bearings 30 and has fastened thereto the guide roller 32. Journal bean ings 33 are fastened to the angle irons 25. A shaft 34-. is journaled in the journal bearings 33 and has fastened thereto the guide roller Journal bearings 36 are fastened to the channel irons 23. A shaft 37 is jour naled in the journal bearings .36 and has fastened thereto the guide roller 38.

A U-shaped trough with the inner wall 10 and the outer wall 41-1 is fastened to the angle irons 26, 27, 28 and 29. The'trough is open at its sides as indicated at 12, and the outer wall 11 is extended at, its outlet end as indicated at 43.

In the top ends of the columns 20 are formed guides 14 for the adjustable cross heads 415. Caps 1-6 are secured to the top ends of the columns 20 and have in threaded engagement the screws 4:7 that bear upon the cross heads 15. The said screws are locked in place by means of the lock nuts 48. The cross heads 45 havejournaled therein the shaft 4-9 and the latter has attached thereto the upper feed roller 50.

A pair of shaft brackets 51 are connected by the foot plate 52 and have formed therein a plurality of pairs of bearings 53. The brackets 51 are located adjacent to the columns 20. A shaft 54; which. has wound thereon long sheet of cloth 55 can be supported. on the various pairs of bearings 53.

A fragmentary portion of similar supporting beams 56 are provided for the cutting machine that may be used with the trough as described in my patent application Serial Number 343,391, filed December 8, 1919, hereinbeforereferred to.

A roller shaft 59 is journaled in the supporting beams 56 has fastened thereto the roller 60 and the sprocket chain wheel 61. Endless conveyer bands 63 extend around the roller 60 at one end and around rollers, not shown, at their other ends. A sprocket chain 64 extendsaround the chain Wheel 61 and sprocket chain wheels, not shown, of the cutting machine. The chain 64 transmits rotation to the shaft 59. A shaft 65 is journalcd in the upper portion of each of the columns 20 and has fastened thereto the feed roller 66. On the shaft is fastened a sprocket chain wheel 67 and on the roller shaft 59 is journaled a sprocket chain wheel 68 having formed therewith one member 69 of a clutch. second member 70 of the clutch issupporte'. on the shaft 59. A spline 71 of the usual construction is interposed between the shatt 5,9 and the clutcn member 70. A bracl'ct extends from one of the supporting beams 56 and has pivoted thereon the operating handle 'Ztwith the forked end 75. The l ter engages the groove 76 of the clutch men. her 70. A sprocket chain 77 connects the sprocket chain wheels 67 and 68. The rot tions of the shaft 59 are transmitted to the shaft 65 through the sprocket chain 'TT and 68 and therefore the wheel. 67 rotates somewhat faster than the wheel 68. The rotation of the sprocket chain wheel 68 is controlled by the operator, by means ot the. operating handle 74:.

l/Vhen operating the feeding apparatus. the shaft '59 is turnedby l-ieans. not shown. o'f the cutting machine whereby the conveyor -bands'63 are mored to talre and conreythematerial that is ted by the trough, after being cut by means, not shown. The rotation of the shaft 59 is transmitted to the shaft 65 through the clutch member" (39 and 7O and thereby the sheet of cloth or other material operated upon. is unwound from the roll on the shatt 54- and (lelirmcd into the trough. During; the charging? of said trough with said. cloth it i. the FldlflC time pulled therefrom by the cutting macl iine over the guide roller The quantity of cloth delivered to the trough depends upon the speed of the element of the cutting machine coasting therewith. and the diameters of. the sprocket chain wheels 7 and 61 :are such that the cloth is delivered to the trough a somewhat greater speed than the speed at which it is pulled there from, by virtue of which undue strains and pulls'on the material operated upon are prevented during its .movemeuts throuqhth trough. The sheets are kept loose in the trough and the banking of the material or cloth-therein has the adiantage of allow 71; the cutting-machine to run on while a fresh roll of fabric is locatedwith its shatt in the bearings 53. It too great an accumulation of cloth or other material collects in the trough. the operator disengages the clutch members 69 and T0 for a short period of time and thereb stops the rotations of the shaft 65. By this means the sheet 5 is stopped from unwinding the material from the roll on the shaft 541..

The siiect of material as it unwinds from the shaft 5%l passes between the teed rollers 50 and 66. from thence into and through the trough and then over the guide roller 35).. The sheet then passes under the guide rollcr 35 and from the latter over the guide roller;- 38 to the cutting machine. not shown.

Various modifications ma he made in the construction oi thc ap iiaratus within thc spirit of the claims, and the prcsent exculplitication is to be taken as illustrntivc and not in a limiting sense.
