GEARING. l
` Application nlearbmary 24, i917.l serial No. 156,652.
To all who/m t may concern;
Be it known that I, HAnMoN a. citizen of the United States, residing at "Whitinsville, `in the county` of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Gearing, of which the following iis a full, true, and concise specification.
This, invention to be hereinafter described relates to roving, spinning and like machines, and more particularly to means for obtaining finer changes in the draft or stretch of the material being operated on by the drawing rolls. In machines as constructed at present the draft arrangement of the rolls consists in the employment of a train of gears comprising the driving gear on the front roll, an intermediate gear meshing therein and driving a short shaft held in a bearing concentric with the front roll. To the other end of this shaft is fixed the change gear which meshes into a gear on the back roll. In this arrangement alterations in the draft between the rolls can be obtained only b using gears of different sizes for the so ca ed change gear. Owing to the limited space that can be devoted to this gear its size is necessarily small; consequently a change of only one tooth results in altering the draft to a greater degree than is sometimes desired. In order to obtain the required draft it is sometimes necessary to change both the intermediate gear and the change gear. This necessitates employing several different swing stands, one for each size of intermediate gear which is objectionable owin to the room they take up in the mill and a so on-account of the work imposed onthe operative in making the changes.
With this general fact in view my present invention aims to produce a more simple, efficient and reliable means for obtaining any desired draft with a minimum number of parts and the least work to the operative; and while it is [herein shown and described as associated with spinning machinery, it is to be understood that the invention may be used in connectionA with other types of machinery requiring chan es in gearing and that in its true scope, t e invention is not l restricted yto the details or particulars as i1- Y f lustrated and described, but may be varied within the denition of the invention as pointed out in the claim.
O. NELSON,` y
Inv thefdrawings; Figure l showsfan end clevationof the draft gearing of a roving frame` with my, `improvement embodied thereon. Fig. 2; lisa rear elevation of the saine. Fig. 3 is a section on line A B of Fig. lshowingthe arrangement for main- `,taining the swing arm concentric with the front roll gear. Fig. 4 is an enlarged view of the swing arm. Fig. 5 is an end view of the slide for the shaft bearing of the intermediate gear. Fig. 6 is a side elevation of the intermediate gear shaft bearing.
Similar marks of reference indicate corresponding parts in all the figures.
It will be understood that the roller beam, marked 1 in the drawings, is the usual construction on which the rolls of a roving or like machine are supported, or above which they are mounted being a lon 'tudinal member extending the full length o the machine.
The drawings show only the ends of the drawing rolls, the front, middle and back of which are marked respectively 2, 3, and 4. These rolls are su ported in the usual manner in bearings not shown) fixed to the roller beam. As usually constructed motion is transmitted from the front roll to the back roll by a train of gears consisting of the front roll gear 5 driving the gears 6 and 7 of a compound gear, the latter gear 7 i driving the back roll through its gear 8. The compound gears 6 and 7 are fixed at 0pposite ends of a short shaft 9 revolving in a bearing integral with the swing arm `10 which swings on a ring 11 integral with standard 12 fixed tothe roller beam; the ring 11 being concentric with the front roll gear insures constant contact between the front roll and intermediate gears for all sizes of the change gear 7. When the gears 7 and 8 are curely held in that state by the bolt 13 clamping the swing `arm and standard 12 together.
As heretofore stated the above construction is objectionable -as it necessitates a different swing arm for each sizeof intermediate gear. To overcome this objectionable feature I provide an adjustable bearing 14: for the compound gear shaft 9 whereby butone swing arm is required for all changes` in the sizes of both the intermediate and roperly meshed they are se- .1
