I Application filed July 11,
To 'aZZ wlwm it may concern:
Be it known that I, RICHARD WATSON, a British subject, residing at Blackburn, county of Lancaster, England, have in-- vented certain new and useful Improvements in Shedding .Motions .for Looms for Weaving, of which the followingv is a specifi'cation. i
This invention relates to shedding motions more particularly applicable for calico looms with a plain shed. 'The object of the invention .is to dispense with tappets and levers or treadles and to provide a positive oscillating motion to operate the healds alternately, and according to the invention an oscillatingor rockbosses to which the heald straps or connections-. are attached.
It is constructed with a crank wheel and connecting rod driven from a rotary part of the loom, a shaft and slotted lever rocked or oscillated by the connecting rodand a second rocking or oscillating shaft geared thereto carrying heald bosses'by' which the healds are operated.
The invention will be fully described with reference tothe accompanying drawings in which sufiicient of a loom is shown to illustrate the invention. 1
Fig. 1. is a front elevation of the improved apparatus. i
Fig. 2 is an end elevation.
Fig. 3 is a perspective view of {bracketlil detached.
Fig.- 4 is a perspective view of gear wheel g detached.
Fig. 5 is a perspective view of connecting rod C detached.
Fig. .6 is a perspective viewof guide bracket F detached.
Fig. 7 is a perspective-view of slotted lever H Fdetached.
ig. 8 is a ers ective view of the ide bracket F det cheii. gu
In carrying out the invention on the side or gable end of the loom a crank wheel A is mounted to rotate on a suitably placed stud 0r shaft 0 and driven b a wheel B from the ordinary crank shaft The wheel A is fitted -with acrank pin a',.which by'be-- ing bolted in one of several holes a a 'therein may be set at any desired distance 1923. Serial in. 650,954.
The connecting rod C is side rods 0 with a number of bowls or runners d d (Z (Z d d at its free end mounted to rotate upon a transverse bar (1 bolted between the two side rods 0. The bowls or runnners d to (l receive a to and fro movement from the crank pin a. as the wheel A rotates. 4
A bracket E bolted to the loom gable carries one or two guide brackets F, (preferably two to give a steady movement) with guide races f f in which the bowls or run.- ners d" 0L and d and d travel as they are rocked to and fro by the crank pin a. The
built up of two guide races are of the shape shown and give wheel g, and affixed to it at or near the centre between the guide races is a slotted lever .H. The two centre bowls (i and 03 of the connecting rod 0 engage with the slot h of the lever H imparting a positive rocking or oscillating motion to the shaft G as the rod C moves to and fro with a dwell at each end as the bowls travel the inclined parts of the faces 7 f.
A second shaft K extends across the loom and is geared to the rocking shaft G by a pinion g and to this shaft the oscillating or rocking motion of the shaft G is imparted. It carries the heald bosses in to which the heald straps k are connected.
. The dwell of the oscillating shaft G at each stroke of the connecting rod C imparts or above the healds, the healds being coninclined or horizontal ide brackets F F" carrying at one end a pmion nected by straps passing over a, roller, or two such motions working synchronously may be employed. one below. and the other ing in combination a crank wheel driven from. a rotary art of the loom, a connecting rod, fixed guide brackets to control and guide the path of the free end of the connecting rod, races in the fixed guide brakets, a shaft and slotted lever oscillated by the connecting rod, the races in the guide brackets being inclined at the ends to provide a dwell for the shaft, a second oscillating shaft geared to the first shaft heald bosses on the second shaft by which the healds are operated and means for varying the dwell of healds. i
2. A shedding motion for looms compris ing in combination a crank wheel, driven the shafts and the lift of the mamas from a rotary part of the loom, a connecting" rod built up of two side rods, a transverse bar at the free end of the connecting rod a plurality of runners upon the transverse bar, races in fixed guide brackets engaged by said runners, a shaft and slotted lever oscillated by the connecting rod, the races inthe guide brackets being inclined at the I G.
