OSCAR A. ALBRECHT, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO O.'A.' ALBRECHT COMPANY, OF OMAHA, NEBRASKA, A CORPORATION OF NEBRASKA.'
FRICTION-GEARING.
To all whom it may concern:
Be it known that I, OSCAR A. ALBRECHT, a citizen of the United States, residing at Grand Rapids, county of Kent, and State of Michigan, have invented certain new and useful Improvements in Friction-Gearing, of which the following is a specification.
This invention relates to friction gearing.
The mesh of the braid formed by a braiding machine depends wholly upon the speed at which the woven braid is picked up or delivered from the machine.
The present invention has for its object the provision of means controlling the speed of the pick-up or delivery mechanism of a braiding machine adapted to cause the formation of a braid having alternate closely and loosely woven sections.
My invention contemplates the provision of an automatic speed-changing mechanism, cooperating with the drive shaft and the pick-up or delivery rolls of a braiding machine whereby the latter are alternately driven relatively fast and relatively slow and hence alternately pull the braid fast and slow to effect the result heretofore set forth.
The invention is not restricted to use with any particular braiding machine and it may be applied to the pick-up or delivery rolls of the machine set forth in my Patent No. 1,073,558, dated September 16, 1913, or to any other braiding machine.
WVhen a braiding machine is provided with my improvements it is adapted to form a braid such as set forth and claimed in my application for braided lacing cords executed September 8, 1916.
One embodiment the invention may assume is set forth hereinafter and shown in the accompanying perspective drawing.
On the take-01f drive shaft A operated from the braiding machine is a cone pulley B and alongside is an auxiliary or countenshaft C carrying cone pulley D. The
pulley D and shaft C are driven from shaft A and pulley B by a friction ring E, preferably of leather.
Worm gears F, G on shaft C androll-i driving shaft H constitute means for transmitting the drive to the usual intergeared pick-up or delivery rolls I, I, I mounted in standards J, J of the braiding machine.
Specification of Letters Patent.
Patented Aug. 2'7, 1918.
A standard J v which has a bearing for shaft H, also supports a revoluble shaft L.
Change speed gears K, K connect shafts a r M is a peripheral cam wheel fixed on shaft L and having a cam groove M composed of alternate dwells, with connect ing inclines.
A bell-crank-lever N, pivoted to standard J 2 at Y, has the end N of one of its arms entering cam groove M and its other arm provided with a loop N loosely interlinked with the ring E.
The gears K, K being removable, any desired change gears, representing any gear ratio, may be employed as it will be understood that the ratio of these gears determines the lengths of braid woven between changes from closely to loosely woven structure.
The pick-up or delivery rolls I, I, I are driven alternately fast and slow, relatively speaking, due to the shifting of the friction ring E by the action of cam groove M on bell-crank-lever and consequently the rolls I, I, I pick up or deliver the braid either relatively fast or slow and, as previously set forth, alternate lengths are woven closely and loosely.
As the invention is susceptible of modification withoutchanging the essential principle thereof, I do not limit myself tothe precise embodiment herein set forth.
atively connected to the roll-driving shaft,
and a speed controller therefor operated by.
the cam.
2. An automatic selective-change-speed drive for the delivery rolls of a braiding ing removable change-speed gears 011 the roll-driving shaft and cam shaft which permit selective changing of the gear-ratio by the substitution of other change-speed gears therefor, a drive shaft, a counter-shaft, gearing connecting the counter-shaft to the roll-driving shaft, cone pulleys carried by the drive shaft and eounterrsha-ft,
respectively, a shiftable friction ring 006perating With said cone pulleys, and a bellcrank lever operated by said cam and adapted for shifting the friction ring.
In testimony whereof, hereunto affix my signature.
OSCAR A. ALBRECHT.
