Specification of Letters Patent.
Patented June 8, 1915.
Application filed November as, 1913. Serial No. 803,371.
T 0 all whom it may concern:
Be it known that I, CHARLES R. SAAT- WEBER, citizen of the United States, residing at 13 Garrison street, in the city of'Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Positive High-;
Speed Shuttle-Motions, of which the fol lowing is a specification, reference being,
had therein to the accompanying drawing.
My invention relates to improvements in looms for weavingsilk, cotton or other fabrics; and the main object ofjmy improvements is to provide, a. positive high speedshuttle motion, which is without limit, within reason. i
Other objects of my improvements are to prevent any undue strain on the filling, to prevent smash-ups and break-downs; to;
provide a series of intermeshing gears and coacting cams all driven from the one shaft to operate the. batten and the shuttlesi, at a;
speed gradually increasing from thestarting point to the center and then gradually decreasing to the stopping, point in either .direction; to prevent the breaking of the.
filling at the edges of the fabric or to. pre-.
vent an uneven selvage, which is sometimes I .caused by the strain upon the filling; to
combine in a loom an eccentric shuttle motion and an eccentrlc batten motion, so as to give the shuttle a chance to start a little sooner and to come home a little later than it otherwise would; to prevent great loss in time and money, and to provide a loom that will turn out work greater in quantity and better in quality. 4 .7
I attain these objects by the mechanism illustrated in the accompanying drawings, i
in which Figure 1 is a plan view of a portion of a loom showing the relative positions of my improvements, and Fig. 2 is a side elevation of a portion of a loom frame embodying my invention.
In the drawings similar letters and numerals refer to like parts.
Upon the stud A, which is secured to the loom frame, are mounted fast and loose pulleys. Motion is communicated to the fast pulley 3 to which is secured thegear 2. The gear 2 meshes with and imparts motion to the gear 2 on the stud A. The eccentric gear E is secured to the gear 2 and meshes with the eccentric gear E which is secured to the main shaft S, re-
volving said shaft S, eccentric E and the gear 41, which is fixed on said shaft inside the 100111 frame; From said main shaft S motion is imparted to thebatten by means of the driving arm 0, one end of which is eccentrically mounted on the stud O,-which is secured onthe eccentric ear E.- The other end of the driving arm 1s ad ustably mounted on the stud 0 which passes throughan elongated slot in a bracket secured to the batten. From the fixed gear 41 on the main shaft S motion is communicated to'an intermeshing gear 42, which is mounted to revolve on the stud B, and thence to the intermeshing gear 43, which is secured to the shaft R inside the loom frame: Actuating cams R and R are also secured to said shaft R outside the frame, side by side, and alternately engage the rollers 5'and 7 which rotate in brackets on the treadles T and T. Said treadles T and T are connected with the smaller portions of the double pulleys P, which rotate on the stud P, by straps M. There are a pair of said double pulleys located side by side, each being provided with a circumferential groove on bOthtllG larger and smaller por thence around the pulleys D in the lower portion of the loom frame, andthence upward substantially perpendicularly, when the batten is in the center or midway of its course, each strap passing over one of the rollers -a-, one strap passing to the right and the other strap passing to the left in a groove in the body of the batten beneath the rack to which they are secured. The shuttles s' are thus operated by the rack and pinions. When the cam It engages the roller 5', pushing the treadleT backward, the cam R permits the treadle T to recede and the straps C are thus alternately pulled, giving the reciprocating movement to the rack, which is imparted to the shuttles s-- through the cooperation of the ordinary or usual pinions.
Only one shuttle is shown in the drawings, it not being deemed necessary to show more than that. It will be obvious, therefore, that there is never any slack straps, when one recedes, the other advances. For instance, referring to Fig. 2, the cam R by engaging the roller 5 has pushed the treadle T back and by so doing has unwound its advantage in many ways. It will beespecially useful when filling of an inferior quality is employed, because it will obviate breaks strap pulley P, causing the double pulley]? to turn, thereby winding its strap G on the larger portion of the double pulley I"; and
referring to the same figure, the cam R has simultaneously permitted the treadle T to R and the rollers 5 and 7 may be provided with teeth, without departing from the scopeof my invention.
By the construction herein describedand shown in the drawings, any desirable speed may be obtained without imparting aje'rky motion, and I obtain a positive high speed shuttle motion which will prove a great and smash-ups.
An essential feature of any invention is the lrregular formation of the cams R and R which are duplicates, each having thesame' large arc-shaped engaging surfaces and small arc shaped engaging surfaces, said arc-shaped engaging surfaces having a com--' I a gear secured to said cam shaft inside the loom-frame, twin actuating cams oppositely mon center, and said cams being secured to a common shaft B, so as to alternately oper- 1 ate their respective treadles T and'T'. This cam construction enables my device to com municate such a motion through the "treadles T and T andother operative connections to i the rack that the shuttles are allowed to lie at rest a portion of the time, while the bat-:
I ten beats the filling up to the fell and while the batten retires half way back before the shuttles i start on their return movements through the warp-shed"to the opposite side of the ribbon.
As with my shuttle motion the shuttles start off easy and-go faster up to thecenter of their prescribed course and then gradually slow down and go easy at the end there-,
' of, the filling will'not drag against the eelvage while thelaybeats up the filling to the ished fabric.
M from the smallportion of its double 5 The eccentric elements of invention and the combination thereof are capable of various modifications to attain the variable speed required in the driving of the batten andv the operating of the shuttles to insure any degree of dwell or rest required preparatory to the flight of the vshuttles in either direction, without departing from the essential spirit or scope of my invention.
With this description of my invention,
what I claim as new and desire to secure by Letters-Patent, is
' L In a loom, the combination with the frame, the battencarrying rack and pinions and shuttles, operativelyconnected with. a a
pair of treadles fulcrumed in the lower portion of said frame, of -a driving shaft and actuating connections including eccentrics to drive from the shaft both' the batten and a the rack, communicating to each a variable speed, substantially as set forth.
2; In a positive high speed shuttle motion for looms, the combination with the frame, the batten, shuttles, rack and pinions carried by the batten, main driving shaft and eccentric driving connections-between said driving shaft and the batten to communicate a variable speed to the batten, of treadles, connections between said treadles and therack, a camshaft mounted in said frame,
arranged and secured to said cam shaft outside the loom-frame and'adapted to-alterand the fixed gear'on the cam shaft, an ec- V centrically arranged gear secured to the main shaft, a gear having an eccentrically arranged elliptical gear secured thereto-and adapted to mesh with the eccentric gear secured on the main shaft and means for communicating power to said series of gears whereby the main shaft is driven at a variable speed so as to drive the shuttles at a variable speed, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES ROBERT SAATWEBER.
