LAPPlNe-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 723,272, dated March 24, 1903. Application iiled January 14,'1901. Serial No. 43,238. (No modeL) To @ZZ wwT/t it. may concern: l

Be it known that I, ROBERT J. HILL, a citizen ofthe United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Forming Bats, of which the following is a specification.

My invention consists of a lapping device` operating on the well-known camel-back principle, but varying from the latter in certain parts and having certain additions whereby it is adapted for making laps Of any width and various thicknesses, `such as are employed in the manufacture of mattresses,

quilts, comfortables, cushions, carpet-lining, .g

stairpads,commercial bats, &c.

The special object of my invention is to provide a lapping device or machine having a wide range of application and which will simplify and improve the process of making said laps. The machine is adjustable to any wid th of lap, thereby enabling me to deposit agood grade of stock on the transverse apron by one carding or garnet machine, an inferior grade of stock on top of that by a second machine, and by a third machine to cover this again with good material, thus producing a fine-surfaced bat at the least expense. y

In the accompanying drawings, Figure 1 is a side view of sufcient of abat-forming machine to illustrate the invention. Fig. 2 is an end View of the same looking in the direction Fig. 3 is a View on a larger scale than Fig. 2, illustrating a part of the machine forming a continuation of that there shown. Fig. 4 is an end view looking in the direction of the arrow w, Fig. 3. Fig.

' 5 is an enlarged elevation of part of the mechanism shown in Fig. 1. AFigs, 7, and 8 are enlarged views of.M parts ofl the mechanism shown in Fig. 1. Fig. 9 is a sectional view of part of the mechanisnishown in Fig. 3, and

Fig. 1 0 is a diagram illustrating the method in which the device is used to form a multiple bat. j

In Fig. 1 part ofthe apron of a cai-ding or garnet machine is represented at l, this apron delivering its web or ieece onto an endless slatted conveyer apron or belt 2, which passes around four drums 3, 4, 5, and 6, the drum 3 frame 7, having rollers 8, which run upon` rails formed by beams or girders 9, mounted upon frames 10, said frame 7 engaging with pins projecting from endless belts or chains 1l, one at each end of the frame 7. These chains at points adjacent to the conveyerbelt 2 are carried and driven by sprocketwheels on short shafts mounted in bearings in the beams 9 and each driven by-means of a chain belt 12 or other suitable power-transmitter from a Wheel or pulley on Vthe shaft of the drum 3, to which shaft power is applied by another' chain belt or equivalent power-transmitter 13, driven by any available shaft of the carding or garnet machine. Back-and-forth reciprocation is thus imparted to the frame 7 to an extent equal to ,the length of the belts 11, and as the distance between the drums 3 and 6 is thus constantly varying there is a corresponding rise and fall of the intermediate drums 4 and 5, which support4 the conveyor-apron 2, and in order to permit this the shaft of the upper drum 4 is carried `by the upper ends of a pair of bars 14, one pivoted at its lower end in line axially with the shaft of the drum 3 and the other pivoted at its lower end to the carriage 7 in line axially with the shaft of the drum 6, the upper ends of the hars being connected together in line axially with the shaftof the drum 4. The shaft of the drum 5 is adapted to bearings l5,movable vertically in a bracketplate 16, secured to one of the bars 14, said bearing-boxes being supported upon springs 17, so that the conveyer belt or apron4 2 is `kept under proper tension inall of the varying angles in respect to eachother assumed by the bars 14 of the carrying-frame.

At each of the ends of the beams 9 are elastic buffer-pins 80, projected by springs 81, contained in sockets 82, which form part of brackets 83, as shown in Figs. 7 and- 8, each bracket having jaws 84 for embracing one of the flanges of the beam and set-screws 85 for securing the bracket to the beam, so that it between which the web or eece delivered by the conveyer belt or apron 2` passes and by which such web or fleece is laid upon the upper run of the conveyer belt or apron 21, which travels in a direction at right angles to the travel of the conveyer-

belts

1 and 2, the vertical adjustability of the rods 18 on the carriage 7 providing for the disposal of the drums 19 and 2O at any desired distance from the upper run of the belt or apron 21, depending upon the thickness of the web which is being acted upon. Y. l

To the upper end of each of the rods 18 is pivoted a lever 22, one arrn'of which carries a weight 23, the other arm of the lever having a pulley or sheave 24, around which passes a belt. 25, which also passes around pulleys 26 on the shafts ofthe drums 19 and 2O and at an intermediate point is caused to pass around or'in contact with a pulley or sheave 27 on the shaft or drum 6, thereby imparting movement in opposite directions to the-

dru ms

19 and 20, so that they will properly lay the web or fleece upon the upper run of the transverse belt or apron 21, the weighted lever 22 keeping the belt 25 under normal tension, which is not interfered' with by the vertical adjustment of the

drums

19 and 20. These features are shown most fully in Fig. 5.

The endless driving-chains 11 are carried at their outer ends by sheaves or pulleys each mounted upon a stud 28, carried by a bracket 29, which has a projecting foot embracing the lower flange of the beam and ,secured thereto by a set-screw 31, as shown in Fig. 6, so as to constitute a clamp whereby the bracket 29 can be secured upon the beam in any desired position of longitudinal adjustment and the chain `belts 11 can thus be kept under proper tension.

In order to compact the web or lieece carried by the endless belt or conveyer 2, I secure to the side beams 14 of the camel-back frame brackets 32, which receive the boxes for the journals of rollers 33, the latter resting upon the web or fleece as it is carried by said conveyer-belt 2.

At one end of its run thetransverse belt or conveyor 21 passes arou nd a drum 35,the shaft.

ings on the frame 38, has at one end a pulley 41 for receiving a suitable `driving-belt and at the other end a spur-pinion 42, which meshes with a spur-wheel 43, turning on a stud projecting from said frame 38, this spur-wheel having a crank-pin 44, connected by a link 45 to an arm 46, hung so as to swing freely upon a shaft 47, to which is secured the drum 48, whereby the endless belt 21 is driven, the shaft 47 also having secured to it a ratchet-wheel 49, with which engages a pawl 50, hung to the arm 46. Hence as the spur-wheel 43 is rotated the arm 46 will be caused to swing upon the shaft 47, andintermittent movements of partial rotation will be im parted to the ratchet wheel 49, and hence to the shaft 47 and drum 48, so as to cause intermittent forward movements of the conveyer belt or apron 21, the extent of each movement being dependent upon theadjustment of a segmental shield 51, loosely mounted on the shaft 47, and which can be adjusted so as to cover more or less of the teeth of the ratchet-wheel within the limit of swing of the pawl 50, thus determining the number of teeth which remain in action,and consequently the degree of fractional rotation imparted to the ratchet-wheel on each swing of the arm 46.

In advance of the drum 48 are a pair of press-rolls 52 and 53, the bearings of the upper roll being suitably controlled, so that any desired amount of pressure may be imparted to them, and the shaft of the lower press-roll is driven from the shaft 47 through the intervention ot' three spur-gears 54, 55, and 56, as shown by dotted lines in Fig. 3, the spurwheel 54 being secured to the shaft 47, the spur-Wheel 56 being secured to the shaft of the lower drumv 52, and the spur-wheel being carried by a swinging arm mounted upon the shaft 47, so that it will properly mesh with the spur-wheels 54 and 56 vand will impart to the lower press-roll 52 movement equal in surface speed to the speed of the belt 21, whereby the web or vfleece will be drawn forward by the press-rolls 52 and 53 just as fast as it is delivered by the belt 21.

A sprocket-wheel 58 on the shaft of the drum 52 drives, by means 0f a chain 59, a

sprocket-wheel 60 on the shaft of a drum 61, y

this shaft being mounted in suitable bearings on the Vframes 38 and serving to drive the shaft of another and similar drum 62 through the intervention of spur-

gears

63, 64, and 65. (Indicated by the dotted circles in Fig. Hence both of the drums 61 and 62 will be rotated in the same direction and at the same surfacespeed.

The drum 66, upon which the bat is to be wound, rests upon the drums 61 and 62 and as the bat is wound thereon rises, each spindle of the drum being adapted to a bearing in a Weight 67, which can slide upon a bar 68, mounted on the frame 38, this Weight determining the degree of compactness with which the bat is Wound upon the drum 66. When the use of the weight is not desired, it may IIO be raised to the "top of the bar 68 and secured thereto by means of a locking-screw 69. In order to guide the journals 4of the drum 66 when the weight 67 is not employed, I may remploy a bar 67a, held in upright position by a catch 68, so that it can be readily released when it is desired to insert or remove the drum 66.

In order to support the web or fleece in its passage from the rolls 52 and l53 to the drum 6l, I employ 'an intermediate supporting-roll 70, as shown. by dotted lines in Fig. 3, this roll being driven from the shaft of the drum 6l through the `medium of sprocket-wheels 7l and 72 and a chain 73 or other equivalent power-transmitting device.

When itis desired to deposit upon the web or fleece upon the 4conveyer belt or apron 21 a coating of size for the purpose yof uniting the surface fibers of the web or securing together successive webs deposited thereon, I

. employ one or more sizing devices, such as shown in elevation in` Fig. 3 and in section in Fig. 9, these sizing devices being suitably located upon the frame 37. On reference to Fig. 9 it will be .observed that the sizing device comprises a pan 75 for containing the glue or other sizing fluid, in which is partially submerged adrum 76, the shaft of which is adapted to `vertically-adjustable bearings in side frames mounted upon the beams 37. vertically-adjustable bearings carry the shaft of a rotating brush 77, thijs brush-shaft and the shaft of the drum 76 being suitably connected, so that said brush and drum will rotate in the directions of their respective arrows, Fig. 7. Upon suitable upright studs 78 on the side frame is mounted so as to be vertically adjustable a blade or strip 79, which can be adjusted from and toward the brush 77 so as to project to any desired extent into the mass of fibers or bristles constituting said brush. Henceas the latter rotates it will gather the liquid glue or other sizing compound from the surface of the drum 76, and when the fibers or bristles are first bent backwardly and then suddenly released by contact with the blade 79 the sizing liquid thus gathered by said fibers will be forcibly thrown or projectedmnto the surface of the web or fleece `upon the endless belt or conveyer 21, and a continuous rain or sprayl of the sizing fluid thus caused to descend upon said web or fleece, so as to impart a uniform covering or coating of 4size to the latter as it is carried forward by the conveyer.

In forming a multiple bat I combine with the single conveyer belt or apron 2l a series of carding or garnet machines, each with its camel-back lapper, as shown, for instance, in

Fig.V 10, in which three of such devices are shown, the web or fleece from the second machine being laid upon that from the first machine and` the web or fleece from the third machine being laid upon the two previously i deposited. By this means I can readily form a bat having any desired thickness and having outer layers of good material and aninterposed layer or layers of inferior material.

Having thus described my invention, I claim and desire to secure by Letters Patent- I. The combination of the reciprocated carriage of a camel-back lapper, a transverse conveyer belt or apron, a pair of drums between which the web or fleece passes from the conveyer of the lapper to the transverse belt, a driving-belt for-imparting rotating movement to said pair of drums, and a weighted lever carrying a sheave around which said drivingbelt passes, substantially as specified.
