DRIVE FOR SPINNING FRAMES R SIMILAR IVIACIIINES.
Application filed December 29, 1927. Serial No. 243,343.
This invention relates to the driving mechanism for a spinning frame or similar machine where the spindles or similar elements occur in large numbers and are driven by belts from a common driving drum.
In such machines, it is of great importance that all the spindles or similar elements shall, so far as possible, be driven at the same speed and that the frictional resistance between the driving belt and each spindle shall be the same. 7 i
The object of the present invention is to secure this esult by driving large groups otthe spindles orsimilar elements, each group by a single belthaving substantially the same degree of frictional engagement with each. p
The object of the invention is further to provide a simple and eilicient means common to two adjacent groups for taking up slack in the two belts and for placing the same tension on both belts.
The nature and objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.
The invention in its preferred form is shown as arranged for the driving ofa series of spindles throughtheir' whirls in a ring has to-do with the driveand as this type of machine is otherwise well known'and fan iliar to those skilled in the art, it is. only necessary here to illustrate and describe those portions of a ring spinning frame wlth which the present invention is directly concerned.
In the drawings:
Fig. 1 is a top plan view, somewhat diagrammatic, of a longitudinal section of a portionof a ring spinning frame.
Fig. 2 is a detail, partially in vertical cross section, showing the driving belt passing around the whirl of a single spindle.
.The elements to be driven are here shown as vertical spindles provided with vertical whirls such as employedin a ring spinning frame. These spindles are indicated diagramn'iatically arranged in long, equally spaced rows, one row at each side of the spinning frame and as the invention only frame, as is usual. The spindles are arranged in groups of e1ght spindles, four at each side of the frame and all drlvenby a single belt. Thus in the first group shown,
there are the spindles l, 2, 3 and 4 at the left, viewing Fig. 1, and 5, 6, 7 and 8 at the right. These spindles are supported as usual upon-the girders or rails 9 and 10 at the sides of the frame. I
Each spindle or similar element may be constructed as desired, but is shown in Fig. 2 as arranged for ring spinning. Here the spindle, such as 4, is mounted in a bearing 11 secured to the girder 9' and carries the whirl 12 around which passes the belt 13.
All the eight spindles of the group are driven by the single belt 13 from the driving drum 14 extending the length of the frame. It is desirable that there shall be substantially the same length of peripheral contact of each whirl withthe belt and a contact of not less than substantially ninety degrees of the periphery and this is secured by the present invention by the arrangement illustrated. An idler roll 15 is located be tween the two rows of whirls and preferably between the drum 1 1 and one row of whirls, such as the row 5, 6, 7 and 8, and midway between. the middle two whirls, such as 6 and 7, of that row. The endless belt 13 passes around the entire group of eight whirls and between the whirls 6 and 7 passes around the idler 15. This belt also passes twice only around the drum 14 and only in the same direction, once between the first and second whirls, as 1 and 2 of the group at the left, and once betwen the second and third whirls, such as 2 and 3 of the same row. That is to say, assuming that the drum is rotating in the direction of the arrow 16, the belt will be traveling in the direction of the arrows shown adjacent the belt. Consequently the portion of the belt shown as running from between the whirls 1 and 2 around the drum and the portions of the belt shown as runningirom between the whirls 2 and 8 around the drum both travel in the same direction. I V I lV-ith this arrangement the desired result is secured and all the whirls of the group will be driven by the single belt under the same conditions.
Preferably, as shown, the endless belt 13 is flat and therefore its flat side must engage each whirl and also the periphery of the drum eaclrtime it passes around the drum. But as the whirls are vertical and the drum is horizontal, deflecting idler rolls 1? and 18 are shown arranged to rotate on a horizontal stud 19 supported on a brache; 20 from the girder 9 adjacent the first row of spindles. The idler roll 17 is located adjacent the second whirl, as 2, engaging the run of the belt from that whirl to the drum and the idler roll 18 is similarly located adjacent the third whirl, as 3, so that the run or the belt in each case which passes from a whirl to the drum isdetlected so that its flat surface passes on to the drum concentric to the drum.
It is necessary to provide means for taking up the slack in the belt and for producing the required tension on the belt. As it is desirable that all the spindles or similar elements shall be run at the same speed and with the same frictional resistance, this invention provides uniformity of these conditions over a large number of spindles. This result is seem-ed by a slack take-up and tension producing means common to two adjacent groups, such as just described.
An adjacent group of spindles is shown, viewing Fig. 1, below the group just described and the arrangement of this second group with respect to all the elements is the same as that described excepting that the entire system is reversely disposed with respect to .the drum. This is indicated by the numbering of the spindles or whirls 1, 2, 3 and 4, and 5, 6, 7 and 8 with the idler roll 15.
The idler rolls 1-5 are both carried by bell cranl: levers tulcrumed at 21 on brackets 22 supported from the respective girders. The longer arms 23 of these bell cranks carry journalled at their ends the respective idlers 15, while the shorter arms 24; are connected by a common contractile connector, herein shown as a rod 25 having a turnbuckle 26 by which its length may be adjusted and a contractile spring 27, the spring and rod being arranged in tandem. It will thus be seen that the spring 2? acts equally on the two bell cranks and causes each idler automatically to take up the slack in its belt and also automatically places the same tension on both belts and that the degree of tension thus placed on both belts is adjustable by means of the turnbuckle 26. Thus the two groups of sixteen spindles in all are driven the two belts at the same speed and under the same conditions and vith the same tension on the driving belts, so that all sixteen spindles are driven under uniform conditions.
Having thus described the invention, what is claimed as new, and desired to be s cured by Letters Patent, is:
1. In a spinning frame or similar machine, the combination ot a horizontal driving drum, :tour spindles having vertical whirls arranged in a row at each side of the drum, an idler located between the two rows of whirls and midway the middle two whirls of one row, and an endless belt passing around the entire group of eight whirls, around the idler, and twice only around the drun'i and only in the same direction, once between the first and second whirls and once between the second and third whirls of the other row.
