VIBBATOR LEVER FOR LOOMS.
Application filed October 20, 1921. Serial NO. 509,128.
To all whom. it may concern.
Be it known that I, WILLIAM M. vVA'l'lIE, a citizen of the United States, residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented a new and useful Vibrator Lever for Looms, of which the following is a specification.
This invention relates to a vibrator lever particularly designed for use in loom harness or drop box mechanisms. These levers support the bearings and stops for the v1- brator gears.
It is the object of my invention to pro vide an improved construction permitting convenient renewal of worn bearings and convenient replacement of vibrator gears whenever necessary.
Preferred forms of my invention are shown in the drawings, in which- Fig. 1 is a side elevation of certain parts of a loom harness mechanism with my improvements embodied therein;
Fig. 2 is a detail sectional plan view taken along the line 2-2 in Fig. 1;
Fig. 3 is a side elevation of a detail part;
Fig. 4 is a sectional view taken along the line ii in Fig. 3; and
Fig. 5 is a view similar to Fig. 3 but showing a slight modification.
Referring to the drawings, I have shown a vibrator lever 10 upon which is mounted a vibrator gear 11 having a link 12 connected for actuation thereby. These parts are in general of the usual and well known construction. The vibrator lever 10 is, however, provided with a dove-tailed groove 13 extending transversely of the lever and adapted to receive a block 14 having two projections 15 and 16 preferably formed in tegral therewith. The projection 15 is adapted to form a bearing stud for the vibrator gear 11 and the projection 16 forms a stop which limits movement of the vibrator gear in each direction.
In assembling the parts the block 1 1 is slipped endwise into the groove 13. A vibrator gear 11 is then mounted on the stud 15 and a fastening member 17 is inserted through the center of the stud 15' and through a corresponding opening in the lever 10. The stud 17 may be riveted or otherwise secured in the lever 10 and is pro vided with a relatively large head which extends beyond the edges of the stud 15 and engages a recessed shoulderlS in the gear 11, thus preventing displacement thereof.
When the parts become worn or broken and replacement is necessary, the stud or rivet '17 may be removed and a new gear or block may be easily substituted without replacing the entire vibrator lever 10.
In Fig. 5 I have shown a slight modification in which the block 18 is symmetrically formed and the projections 19 and 20 are identical. As there is practically nowear on the projection which serves as a stop, this modified construction permits reversal of the block after the hearing has become worn and thus doubles the useful life of a single block.
Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art within the spirit and scope of my invention as set forth in the claims and I do not wish to be otherwise limited to the details herein disclosed but what I claim is 1. In a loom, having a vibrator gear, in combination, a vibrator lever, a block detachably secured to said lever, and bearing and stop projections fixed on said block, said bearing projection supporting said gear and said stop projection limiting angular movement thereof.
2. In a loom, having a vibrator gear, in combination, a vibrator lever having a transverse groove therein, a block removably secured in said groove, and bearing and stop projections mounted on said block and supported thereby, said bearing projection supporting said gear and said stop projection limiting angular movement thereof.
3. In a loom, having a vibrator gear, in combination, a vibrator lever having a body with a transverse dove-tailed groove formed therein, a block slidab-le in said groove and having bearing and stop projections thereon, and means to hold said block in said groove, said bearing projection supporting said gear and said stop projection limiting angular movement thereof.
4. In a loom, having a vibrator gear, in combination, a vibrator lever having a body with a transverse groove formed therein, a block positioned in said groove and having bearing and stop projections thereon, and a fastening member extending through said block and fixed in said lever, said member block being reversible and said bearing and 10 having an enlarged head adapted to retain stop projections being identical, said bearing said gear on said bearing projection; and projection supporting said gear and said said stop projection limiting angular movestop projection limiting angular movement 5 ment thereof. I 7 thereof. r y 1 5. In a loom, havingavibrator gear, in In testimony whereof I have hereunto 15 combination a vibrator lever, a block deafiixed my signature. tachably secured to said lever, and bearing and stop projections fixed on said block, said VVILL-IAM M. VVATTIE.
