JOHN' F. SCHENCK, JR., OF SHELBY, NORTH CAROLINA.'
stivale-nar MAcHrNE.
Application filed September To all whom t may concern:
Be it known that Jol-1N F. ScHnNoK, J r., a citizen of the United States, residing at Shelby, in the county of Cleveland and State of North Carolina, has invented new and useful Improvements in Sliver-Lap Machines, of which the following is a specification.
This invention relates to cotton spinning machinery and particularly'to Aan improvement in sliver lap machines and the like, and proposes the construction of novel means for releasingthe lap from the driving rolls at the time ofdoffing the full lap.
As is well known to these skilled in the art, a number of card sliversare taken bythe sliver lap machine subjected to draft to draw the fibers into parallelism and fornfiec` into a wide lap or 'ribbon which is wound into a roll by the sliver lap machine from which it is taken or defied to be subjected te later processes in its course through the mill. In present lap machines the lap is wound upon a roll by fri-ctional contact of that part of the lap already wound with the driving rolls. The operation of doffing requires that the fully wound lap roll be raised out of. engagement with the drive rollsvso that the filled roll may be removed'and an empty roll substituted therefor. This, in ordinary practice, is accomplished by manipulation of a hand wheel at the side of the machine and requires that the operative, whose normal work demands that he stand in front of the machine, facing the roll, shall be forced to reach over to one side, bending his body almost at right angles. As the sliver lap machine must be doffed every eight or ten minutes and each operative attends from three to six machines, itis obvious that the labor is fatiguing and the capacity of the operative necessarily limited.
One of the objects of the present invention is to substitute, for the usual hand wheel, means for releasing the wound lap from thedrive rolls accessible to the operative from his standing position and automatically returnable to normal position after having been actuated.
Another obj ect of the invention is the provision of lifting means for the lap roll within easy reach of the operative from his standing position, normally inactive during the self-rise of the lap while building up on the roll, and manually operable to engage with lap roll raising mechanism to lift the 15, 1922. Serial No. 588,367..
lap .from the drive rolls, there being automatlc means associated with 'said lifting means to cause its release from said lap roll raising mechanism and itsfreturn to normal position. l Y
Specifically, the Aobject of .the invention `is the construction of a hand lever journalled uponvthe lap roll lifting shaft of a sliver lap machine and engageable with said shaft at will by manipulation'of a pawl and ratchet mechanism to operate said shaft, and means associated with said lever for causing its automatic return Vto normal position.
'With the above and other objects in view, my invention consists in the improved sliver lap machine illustrated in the accompanying drawings, described in the following speci# fication, and particularly claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.
in the drawings accompanying and'forming a part of this specification, and wherein the preferred embodiment of my invention is illustrated: f
Figure 1 is a side view of aportion' of a sliver lap machine having an embodiment of my invention applied thereto. u
Figure 2 isa" side elevation ofthe machine illustrated in Figure 1 the hand lever being shown in full lines in engaged position with the ratchet on the lap roll vlifting shaft, and in dotted lines in disengaged position.
Figure 3 is an end machine.
Figure Llis a view in perspective showing my improved hand lever.
Referring now in detail to the several figures, the numeral 1 represents the frame of the sliver lap machine which supports bearing blocks 2 and 3, each of which afl'ords bearings for the friction drive rolls i and 5. rllhese drive rolls are driven by a single intermediate gear 6 from a'source of power, not shown, and they therefore rotate in the same direction. A. sliding frame formed by a pair of uprights 7 and 8, best shown in Figure 3, is positioned in a plane passing between said rolls at .their point of closest approacln said frame -carrying bearing blocks 9 and 10, Figure 3 in which is journalled a shaft 11. The bearing block 9 and the outer end of the shaft 11 are formed with complementary breech block elements 12 and 13 and the shaft 11 is provided with al hand wheel 14, so that when the hand wheel is view of the sliver-lap l CFL means being releasable from said shaft to permit the descent by gravity of said fra-me independently of said operating means.
2. In a sliver lap machine, a roll-carrying frame, a shaft for elevating said frame, operating means jonrnalled on said shattand having a normal position {When inoperative, engaging means carried bysaid operating means for engagement with said shaft' to rotate the latter for elevating said frame, said engaging means being releasable from said shaft to permit the descent by gravity of said frame independently of said operating means and means tor automatically returning said operating means to normal position. y
'3. A sliver lap machine, a roll-carrying trame, a shaft for elevating said frame, operating means journalled on said shaft and having a normal position when inoperative, engaging means carried by said operating means for engagement with said vshaft to rotate the latter for elevating said frame and being automatically releasable Jtrom said shaft to permit the descent by gravity ot said frame independently of said operating means, and means 'for automatically returning said operating means to normal position.
4. In a sliver lap machine, a roll-carrying frame, a shaft, cooperating means on said shaft and frame for elevating the latter, a pinion on said shaft, an operating lever journalled upon said shaft and having a normal position when inoperative, a pivoted paWl carried by said lever and normally out of contact with said pinion, means for depressing said pavvl into engagement With 'said pinion to permit rot-'ation of said shaft by said lever and a Weight secured to said lever to cause the automatic return of the latter to normal inoperative position.
5. In a sliver lap machine having a supporting' frame, a roller-carrying frame, a shaft for elevating said roller-carrying frame, a hand-lever journalled on said shaft and provided With means engageable with the teeth of said pinion, means on said handlever for actuating' the engageable means, the hand-lever projecting upwardly and for- Wardly to a position above and forwardly of the front of the frame of the machine.
In testimony whereof I afiix my signature.
