GLOTH-GARRYING MACHINE.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed April 29, 1910. Serial No. 558,525.

To all whom it may concern:

Be it known that I, STANLEY HARDY, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Cloth-Carrying Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention consists of an improved machine for conveying cloth and the like, and is particularly adapted for handling duck, such as is used in making awnings, tents, and similar articles.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a top plan view of the machine; Fig. 2 is a side elevation of the machine; Fig. 3 is an end elevation of same; Fig. 4 is a side elevation, on an enlarged scale, of part of the machine, showing the cloth-feeding mechanism and parts in conjunction therewith; Fig. 5 is an end elevation of the part of the machine depicted in Fig. 4; Fig. 6 is an enlarged transverse sectional view of Fig. 4, showing the means for driving the cloth-feeding means; Fig. 7 is a detailed View, on an enlarged scale, of the cloth-clamping device; and Fig. 8 is a sectional view on the line 88, Fig. 7.

The main frame of the machine is dis posed above a table 1 or the like and is preferably formed of angle-irons 2, which are connected in pairs by means of plates 3, said pairs being connected with cross braces 4. An auxiliary frame is supported from a ceil ing 5, or other support above table 1, and is formed of angle-irons 6 that are depended from said ceiling and are connected by means of end braces 7 and side braces 8. Angle-irons 9 or the like at the ends of said auxiliary frame support journal-boxes 10 for shaft 11 upon which a pair of drums 12 are mounted, one of said drums being located at one end of said frame and the other one of said drums being disposed at the other end of said frame. Each drum 12 is provided with a pair of cords or ropes 13, preferably wire, said cords being fastened to said drum so that, when shaft 11 is r0- tated in one direction or another, said drum causes said cords to wind or to unwind simultaneously. A cross-piece 14 is located beneath said drum, and connects a pair of members 15 that is fastened to rods 16, which support the main frame of the machine. Members 15 are connected to a pair of turn-buckles 17 that is fastened to cords 13, respectively, said cords being arranged to pass over rollers 18 which are supported in any suitable manner from angle-irons 6. By means of the turn-buckles 17 the corners of the main frame of the machine can be raised or lowered in order to cause said frame to occupy a horizontal position. When shaft 11 is rotated in one direction or another, drums 12 wind up or unwind cords 13, whereby the main frame of the machine is raised or lowered to increase or diminish the space between said frame and table 1 in order to allow a large or small amount of cloth to be deposited upon said table in the manner hereinafter described.

Shaft 11 is arranged to extend beyond one end of the auxiliary frame and is journaled in a journal-box 19 that is supported from a wall or upright 20. A sprocket 21 is secured to said shaft and is driven with a chain 22 that is driven by means of a sprocket 23 on shaft 24. Said shaft 24 is journaled in journal-boxes 25 on bracket 26, which is fastened to wall 20, there being a crank handle 27 or the like secured to said shaft 24 in order to rotate same. A pawl 28 is pivoted to one of said journal-boxes 25 and is arranged to cooperate with the teeth of a ratchet 29 on shaft 24 to prevent shaft 24 from rotating backward, thereby holding the main frame of the machine at any desired elevation.

A roll of cloth 80 is supported in any suit able manner from a pair of sideboards 31 that is supported by means of a frame 32, said frame being located adjacent one end of the'main frame and arranged to support an apron 33. The ends of said frame 32 are preferably screw-threaded and are bent downwardly to extend through perforations in said pairs of angle-irons 2, respectively, each of said screw-threaded portions being provided with a nut 84 or a plurality of such nuts to hold said frame in place and, also, to adjust same vertically. The cloth 35 extends between a pair of cloth smoothers or guides 36 and then passes between a pair of feed-rollers or. Said smoothers are preferably formed of sheet metal and are fastened to rods 88, respectively, that are supported from the sideboards 31, each of said rods being provided with an arm 89 to which a weight 40 is attached in order to press such cloth smoothers toward each other with theresult that the cloth 35 passing therebetween is freed from all wrinkles and creases before it passes between feedrollers 37. Said feed-rollers are loosely in engagement with sprocket wheels 47 mounted on shafts 48, which are journaled ,in journal-boxes 49, said journal-boxes be ing supported by the main frame of the machine and arranged to be adjusted by means of'set-screws 50 or othersuitable means to regulate the, tension of said chains. The oonveyer extends from one end of the machine to the other, and the width [thereof about equals the width of the machine. One shaft 48 is located at one end of the machine and another shaft 48 near the other end, the latter shaft being the driving shaft of the machine and being driven from any ldesirable source. One of the shafts 41 extends beyond a sideboard 31 and" bears a sprocket 51 that is driven with a chain 52,

.said chain being driven by means of a sprocket 53 on said driving shaft 48. A clutch 54 is feathered tosaid shaft41 and is arranged to be shifted into and out of engagement with a clutch 55 borne by feedroller 37 on said shaft, whereby'sa id roller is caused to rotate or to remain at rest. A member 56 encircles clutch 54 and bears a pair of rollers 57 that extends into an annular groove 58 in said clutch, said member being pivoted at 59 to a bracket 60 and arranged to be operated by means of a lever 61 or the like in order to move clutch 54 into engagement with clutch 55, a spring 62 being arranged to hold said clutch 54 normally out of engagement with said clutch 55.

Each slat 46 is provided" with a pair of clamps 44. Each clamp 44 is formed of a finger 63, which is pivoted by means of a bolt 64 or the like to lugs 65 and 66'of a plate' 67. Plate 67 is located at an. end of a slat 46 and is fastened thereto by means of bolts 68, which, also, secure a link 69 of a chain 45 to said slat, said plate being grooved at 70 and arranged to allow said finger to move in a plane extending longitudinally of said slat so that, j when said finger is depressed in the manner herein after described, same enters a similar groove 70 in slat 46 in order to clamp the cloth to :said slat. A spring 71 fastened to lug 65 by means of stud 72 is arranged to hold finger 63 out of groove 70. A member 73 ispivoted at 74 to lugs 66 and 75 and is arranged to rotate in a plane substantially at a right-angle to the plane of finger 63. Each side of the main frame of the machine is provided with a sprin 76, which is arranged near apron 33, an is located in the path of travel of an arm 77 of said member 73. Another arm'78 borne by member 73 is arranged to depress finger 63 when said member is rotated toward said finger, the

end. of said arm 78 being notched at 79 in order to hold finger 63 in groove 70. When slat 46 travels around drive shaft 48, the arm 77 of member 73 engages spring 76 with the result that said member rotates toward finger 63 and causes arm 78 to depress said finger, thereby causing said finger to enter groove 70 and, also, to enter notch 79 in the end of arm 78 which holds said finger firmly in groove 70.

The cloth 35 passes over the edge of apron 33 and engages a slat 46 when said slat travels past said apron, and, as the fingers 63 are depressed-in the manner hereinabove described, said fingers clamp said cloth against said slat and draw same over table 1. While the endless conveyor 43 travels along, the pair of clamps on the next slat 46 take hold of the cloth in the same manner, and so on until the desired length of cloth has passed over apron 33. The machine may then be stopped and the cloth cut by hand across apron 33,

or if desired, the cloth-cutting device disclosed in'my United States Letters-Patent No. 925,096, granted June 15, 1909, may be used for cutting said cloth. After the cloth has been cut at the desired length, it is carried by the conveyor 43 to a position to be deposited upon table 1. In. order to release the cloth when same reaches the place where same is to be deposited upon table 1, a shaft 80 is provided that is arranged to extend crosswise of the main frame and is journaled in members 81 borne by said main frame, said shaft being rotated by means of a crank handle 82 or the like. A pair of miterwheels 83 is mounted upon shaft 80, and meshes with a pair of miter-wheels 84 mounted on a pair of crank shafts 85, respectively, one shaft 85 being arranged to extend along one side of the main frame and journaled in supports 86 borne by said frame, and the other shaft 85 being arranged to extend along the other side of said frame. When the cloth 35 reaches the desired position to be deposited upon table 1, the shaft 80 is rotated, which causes the crank shafts 85 to rotate, with the result that said crank shafts strike the arm 77 of each clamp 44' adjacent thereto and cause arms 78 to release their respective fingers 63. Each of said fingers returns to its normal position by the pull of its spring 71 and allows the piece of cloth to drop upon table 1.

As an additional means for support-ing the endless conveyer 43, each slat is provided with a pair of members 87 that bears a pair of rollers 88, respectively, one member 87 being located at one end of said slat and the other member at the other end. As the endless conveyer 13 travels along, the rollers 88 of each slat 46 on the upper side of said conveyer ride upon the upper angleirons 2 of the main frame of the machine, while the rollers 88 of each slat 46 on the lower side of said conveyer ride upon the lower angle-irons 2 of said frame,

When the pieces of cloth that are deposited upon table 1 in the manner hereinabove described pile upwardly upon table 1 so that it becomes necessary to raise the main frame of the machine in order to allow more pieces of cloth to be deposited upon said table, the crank handle 27 is rotated in the direction to cause drums 12 to wind up cords 13 with the result that said cords raise the main frame of the machine to the desired elevation.
