Specification of Letters Patent.

Patented Nov. 28, 1905.

' Application filed February 10,1905- erial No. 245,063.

To ail whom, it may concern:

Be it known that we, CHARLEs SCHOFIELD and ISAAC REEDER, citizens of the United States, and residents of Philadelphia, Penn sylvania, have invented certain Improvements in Lap-Feeding Devices for Carding-Machines,of which the following is a specification.

Our invention. relates to that class of lapforming devices for carding-machines in which the web or fleece from the delivery-apron of one carding-machine is folded back and forth .upon a transverse apron running at right angles to the direction of movement of said delivery-apron for the purpose of conveying the lapped web or fleece to a second cardingmachine alongside of the first.

Our invention relates especially to the means I employed for receiving the web or fleece from the delivery-apron of the first carding-machine and conveying the same to and lapping it upon the transverse conveyer-apron, the

purpose of our invention being to effect such conveyance of the web without injury thereto and to impart to-and-fro motion to the devices which direct the web or fleece onto the transverse conveyer-apron and also feeding or carmanner hereinafter set forth, reference being bad tothe accompanyingdrawings, in which Figure 1 is a side View of a lap-feeding device for carding-machines constructed in accordance with our present invention. Fig. 2 is a plan view of the same, and Fig. 3 is a transverse section on the line a a, Fig. 1.

1 represents the deliverybelt or apron of the carding-machine, which receives the thin web or fleece from the dolfer or other member of said carding-machine, said apron being mounted upon drums upon shafts 2 and 3, which are adapted to suitable bearings in a frame comprising side bars each composed of members 4 and 5 rigidly secured together, and a transverse rod\6 connecting the outer ends of the bars 5, said frame being supported by means of suspension-rods 7, which are hung from a suitable fixed support above the machine. The shaft 2 has achain or spur wheel 8, whereby it is rotated from some convenient rotating member of the carding-machine, and said shaft also has a sprocket-wheel 9, to which is adapted a chain belt 10, the latter also engaging a sprocket-wheel 11, secured to the shaft 3, and a sprocket-wheel 12, which is secured to a shaft 13, the latter being adapted to bearings in the arms 5 and having secured to it a drum 14, as shown inFig. 2. To similar bearings inithe arms 5 is adapted another shaft 15, which is provided with a drum 16, and depending from and free to Swing on said shafts 18 and 15 at each end of the same are arms 17 and 18, each arm 17 being connected at its lower end to the adjoining arm 18 by means of a link 19*, as shown in Fig. 1.

The lower ends of the arms 17 and 18 constitute bearings for shafts 19 and 20, which carry

drums

21 and 22, and mounted upon said drum 21 and upon a drum 23, whose shaft is adapted to bearings in the arms 17, is a conveyer-apron 24, another conveyer-apron 25 being mounted upon-the

drums

16 and 22, so that the web or fleece delivered from the conveyer-apron 1 will first pass forwardly over and around the drum'14 and then downwardly between the aprons 24 and 25 and will be deposited upon the transverse conveyer-apron 26, which is disposed beneath the structure which we have'just described and is mounted upon suitable drums whose shafts turn in fixed bearings on the floor, said transverse conveyer-apron extending laterally to any-desired position where it has to deliver its load to the feeding devices of the other cardingmachine. The said transverseconveyor-apron may deliver to or may form part of What is termed a-camel-back, whereby the web or fleece is lapped upon the feeding-apron of the second carding-machine.

By the use of the drum 14 we overcome an objection which applies to apparatus in which the web or fleece is fed directly from the apron 1 to the upper portions of the directing-aprons 24 and 25. Where the apron 24 passes around its upper drum 23, the slats of the apron are separated, and when the apron passes from the curved'to the straight course the slats approach each other, andhence have a tendency to nip the fibers of the web. When the drum 14 is used, however, the webdoes not come into contact with the apron 24 until the latter has assumed its downward course and its slats are close together.

In order to impart swinging movement to the arms 17 and 18, so that the aprons 24 and 25 may lap the fleece back and forth upon the surface of the transverse conveyer-apron 26, a shaft 27 is adapted to suitable bearings in brackets projecting upwardly from the arms 5, and this shaft is provided at each end with a spur-wheel 28, which meshes With a spurpinion 29' on the shaft 3, said spur-wheel 28 having a series of openings 30 at different distances from the center of the same, to either of which openings may be adapted a crankpin 31, which engages one end of a link 32, the other end of said link being connected to an arm 33, which forms an upward continuation of the arm 18. As the spur-wheel 28 is rotated, therefore, swinging movement will be imparted to the arms 17 and 18, the extent of this movement being dependent upon which of the openings 30 in the spur-wheel 28 receives the crank-pin 31.

Rotary movement is transmitted from the shaft 13 to the shaft 15 through the medium of a pair of interposed and intermeshing spurwheels 34 and 35, and movement is transmitted from the shaft 13 to the shaft of the drum 23 by a chain belt 44, adapted to sprocketwheels on the two shafts.

Hung to a pivot-pin 36 on a bracket at the lower end of each of the arms 17 is a link 37, which constitutes a bearing for one of the journals of the spindle of a drum 38, and in like manner the arms 18 carry pivot-pins 39 for links 40, which .carry the spindle of a drum 41, and said drums 38 and 41 are rotated in the direction of the arrows shown in Fig. 1 by means of chain belts 42 and 43,

adapted to sprocket-wheels on the shafts 13 and 15 and on the spindles of the drums. These drums 38 and 41 serve to lay the web or fleece properly upon the surface of the transverse conveyer-apron 26, and, if desired, can press upon the upper layer of each lap, so as to compact said lap upon the apron, adjustment of the drums 38 and 41 in respect to the upper surface of the apron 26 being effected by simply loosening the nuts upon the pivot-pins 36 and 39, swinging the links 37 and 40 in one direction or the other to the proper extent and then again tightening said nuts.

It will be observed that our improved lapfeeder constitutes an attachment which is complete in itself and can therefore be readily applied to any carding-machine without requiring any modification in the structure of the latter, and, further, that the mechanism for swinging the depending frame which carries the directing-aprons 24 and 25 has no connection with the carding-machine proper and is located wholly at the top of the attachment,

so that the lower portion of the swinging,

frame with its directing aprons and drums is accessible on all sides to permit of ready access to any part of the fleece or web which is being laid upon the transverse conveyor-apron 26.

Having thus described our invention, we claim and desire to secure by Letters Patent- 1.
