ARTHUR G. BOOZER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR O13 ON E-HALF TO GEORGE HILL, OF TUCAPAU, SOUTH CAROLINA.
STRIPPING MECHANISM FOR CARDING-MACHINES.
Specification of Letters Patent.
Application filed April 12, 1918. Serial No. 228,263.
To all whom it'may concern:
Be it known that I, ARTHUR G. Booznn, a citizen of the United States, and resident of Providence, county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Stripping Mechanism for Caroling-Machines, of which the following is a specification.
My invention relates to certain improvements in pneumatic or so called vacuum strippers for card-clothing of the cylinders of carding machines, one of the objects of the invention being to provide means for stripping either one or all of the cardclothed cylinders during the productive operation "of the carding machine. Another object of "my invention is to provide simple and effective means for stripping the cardclothed cylinders, which is not liable to be clogged'by the fibers, neps, dust and foreign matter that pass through the suction nozzles, or are present in the vicinity of the carding machine. Another object of this invention is to provide stripping mecha nism for carding machines in which several suction nozzles are aimed to extend across the card clothed cylinder, the nozzles being renderedefi'ective in non-consecutive order, whereby each nozzle acts upon a nomadjacent portion of the circumference of a rotary cylinder.
My invention is distinguished from the prior state of the art in tha'tthere isipresent a transverse series of suction nozzles maintained adjacent to the teeth of the cardclothing of a cylinder or flat, the :pipes or conduits associated therewith each having an independently actuated hinged valve, such valve and its actuating means being such as to obviate the "liability of becoming inoperative "by the s'trippings, and in that the suction nozzles are rendered operative in non-consecutive orderto'be-efl'ective upon disassoc'iated or non-adjacent portions of the clothing ofthe cylinder to bestripped.
My invention is designed to provide strippingmechanism oftheisuction type which will not'be clogged 'by-the fiber,1ieps, dust and foreign articles that-are drawn into the nozzles and are present in a carding room, and "to place the operating mechanism so as to avoid undue encroachment upon the aisle space and to simplify the construction of the parts and operating means therefor, as will be hereinafter set forth.
In the accompanying drawings, Figure I is a side elevation, partly in section, of a suction nozzle, its valve and valve operating cam, constructed to accord with my invention. Fig. II is a perspective view of the valve. Fig. III is a plan view of the suction nozzle. Fig. IV is a diagrammatic view showing an arrangement of the cams which operate the valves of the suction nozzles.
Fig. V is a view showing the transverse re lation of the suction nozzles and a shaft having thereon cams to one of the cylinders of a carding machine, and Fig. VI is a side elevation showing several applications of the strippers to the cylinders of a carding machine.
Referring to the drawings which illustrate a preferred embodiment of my invention 10 designates a suction nozzle which is attached to or formed integral with a flanged member 11, which member may be a casting, and the nozzle may be made of sheet metal witha hollow end that fits into the open end of the flanged member 11,
which maybe tubular or rectangular. The
The suction nozzlesare connected to .conduits orpipes 13 that have end flanges with apertures :to receive bolts or screws, for attaching the nozzles to said section of the suction'system, andthe'conduit 13 to'avalve carrying'section. The conduits l3n1ay be of any suitable shape and carry a lug 'or lugs lito receive a bar 15, for connecting the sections to the frame of a carding machine, and adjacent to the lugs '14 there is Patented Janie, 1 920.
an apertured projection 16 for a spring.
spaced to admit of the section 13 being coupled to the section of the suction conduit having a valve, and to the nozzle to properly position the nozzle relative to the teeth of the card clothing. The supporting rod 15 between lugs 14: may carry spacing tubes or sleeves and the ends of the rods engage with the side frames of the carding machine.
The flanged ends of the conduits or pipes 13 are coupled by means of screws or bolts to one end of a section 17, that has associated therewith a hinged valve, such section 17 being connected in any suitable manner with a pipe 18, which leads to a receiving chamher and a vacuum or suction pump, located at a central station where the strips removed by the nozzles are separated from the neps, dust and other waste. It will be understood that the pipes 18 may be a part of an overhead vacuum or suction system, or may be supported upon the floor or alongside of the frame of the carding machine.
The valved section 17 is constructed to be coupled to the pipes 13 and 19, and an intermediate portion of the section 17 has parallel flat sides and a side at right angles thereto and opposite the last mentioned side there is an opening and means for attaching to the section a hinged or oscillatory valve 20. The section 17 may be a one piece casting or it may be made in sections, and adjacent to the upper end of the opening are apertured lugs or bosses to receive a removable pintle 21 upon which the valve is oscillated, and below the lower portion of the opening there is a transverse stop 22, against which projections 23 and 24 will engage. The valve 20, is of such construction that when moved in either direction it serves as a closure for the opening through the section to which it is attached. As shown by Figs. I and II, the valve 20 has an inclined face 20' which terminates above a straight-across face 2 1 that abuts against the section 17 opposite the opening therethrough, and when the valve is moved to admit air into the nozzle there will be no obstructions and the strippings will be carried by suction to a receiving chamber. When the valve is positioned to cut off the suction from the nozzle, should there be any leakage it will be stopped by the strippings drawn into the tube, which strippings will be released when the position of the valve is changed. The hinged valve may be readily removed from the section 17 by taking out the pintle 21. The hinged valve 20 has attached thereto or formed integral therewith an arm 25, that carries a roller or wear piece 26 which is held against the face of a cam or recessed disk 27 by a spring 28, the ends of the spring being attached to the arm 25 and to the lug 16,
The disks or cams 27 are mounted on a shaft 28, that is driven by a belt that engages a fixed pulley adjacent to which is an idle pulley, and suitable. means may be provided for shifting the drive belt to the fixed or driving pulley when a cut off valve in the conduit is turned to establish communication with a suction pump. In practice when a carding machine is provided with, for instance, eight nozzles there will be a like number of cams 27 which may be arranged as shown by Fig. IV, the recesses being positioned so that the valves 20 will not be operated successively, but by preference in the order indicated by the small numerals 1 to 8 inclusive, (see Figs. I and IV. of the drawings,) the object of such arrangement being to avoid bringing adjacent nozzles successively into operation, as that would be liable to produce in the sliver or product of the carding machine thin places. When a cylinder or flat is stripped the suction is cut off by operating a valve (not shown) attached to the pipe 18.
The stripping device hereinbefore described may be applied to either one or two places to strip the main cylinder, and is ap' plicable to the doffer cylinder, the flats and to the licker-in, several applications being shown by Fig. VI'of the drawings, and Where a single carding machine is: provided with several series of suction nozzles or stripping mechanism of the construction hereinbefore described, each stripping mech anism may be connected to a suction pipe common to the particular carding machine, and such )ipes will be connected to a suction pipe t at is common to several or all the ca rlclling machines in the carding room of the m1 The invention set forth in the claims obviates the objection to rotary valve mechanism, which has heretofore been applied to stripping mechanism for carding machines, and I consider rotary valves objectionable, as in use the strippings have a tendency to mass between rotary surfaces and form a packing or dense mass that will stop the rotation of contacting parts. I am aware that it has been proposed to provide an ap paratus for cleaning the cylinders of carding machines by means of suction nozzles which extend over the entire width of the cylinder to be stripped, pipesfrom the noz zles being connected to a plate having aseries of concentric apertures, and a suction pipe having an end which is moved to cover and uncover successively the apertures, the movable end of the suction pipe being operated by a pawl and ratchet mechanism. The construction of the mechanism and arrangement of the parts is such as not to avoid the objection to rotary valve mechanism, and is also objectionable in that its construction is such as to encroach to a prohibitive extent upon the aisle space between the carding machine.
I claim 1. In a vacuum strippin mechanism for carding machines, a plurality of stripping nozzles, a suction conduit common to each of the stripping nozzles, pipes connecting the nozzles to the conduit, valves maintained by the pipes, and actuating means for the valves operating indix idual valves in nonsuccessive order to establish communication between non-adjacent nozzles and the conduit.
