4 Claims.

particularly to a spinning or twisting machine having driving means for a large number of spindles by a. single motor dr'ven belt'extending a the length of the machine.

An object of the invention is toprovide an improved continuously acting take-up or tensioning means for the spindle driving belt to maintain the. tension therein uniformly constant at all times during operation of. the machine.

Another object of the invention is to provideconveniently accessible means to adjust the tension of the belt during operation if necessary.

- And finally it is an object of the invention to provide a motorand driving pulley for the belt upon a carriage mounted at one end of the machine for movement in a direction to vary thetension in the spindle driving belt.

A feature of importance of the invention is pressed in a direction and with sufiicient pressure to maintain proper driving contact between the belt and the spindles.

Another feature of importance is that the carriage supporting the [driving motor and pulley is mounted upon suitable grooved wheels movable upon laterally spaced rods extending horizontally and longitudinally of the machine at one end. 1

And another feature of the invention that is advantageousis that a pair of helical springs fastened at one end to the machine end frame are attached at-their opposite ends to a plate threadedly connected to-a rod the opposite end of which abuts against an end surface of the motor carriage so that by turning the rod the plate is moved toward or away from the end frame and the tension of the springs is varied.

With the above and other objects'in view the invention may include the features of constructlon and operation set forth in the following specification and illustrated in the accompanying drawings.

In the accompanying drawings annexed hereto and forming a part of this specification, I have shown the invention embodied in a textile doubling and twisting machine of standard form but it will be understood that the invention can be otherwise embodied and that the drawings are 50 not be to be construed as defining or limiting the scope of the invention, the claims appended to this specification being relied upon for that purpose.

. In the drawings; 55 Pig. 1 is a plan view of an end rdcn oi a that the motor carriage is constantly spring i the machine.

. (01. 57-105) This invention relates to textile machines and textile machine to which the invention has been applied;

Fig. 2 is a front elevation partly in section of the parts substantially as shown in Fig.1, and

Fig. 3 is a side elevation of one of the details of construction.

In the above mentioned drawings there has been shown but one embodiment of the invention' which is now deemed preferable, but it is to be understood that changes and modifications may be made within the scope. of the appended claims without departing from. the spirit of the invention.

Briefly, and in its preferred aspect, the invention may include the following principal parts: First, an end frame forming part of the textile machine; second, a motor supporting carriage movable along a guideway fastened to the end frame; third, a rod or arm attached at one end to the motor carriage and extending longitudinally of the machine, a portion of this rod being threaded; fourth, a cross'arm supported on the rod and engaging the screw threads on the inner or free end thereof; fifth, springs at tached at one end to the cross arm and at their opposite ends attached to brackets secured to the end frame of the machine; and sixth, means to rotate the arm or rod to vary the position of the cross arm and the tension of said springs.

Referring more in detail to the figures of the drawings there is shown at It a motor supporting frame spaced from an end frame 9 of a textile machine and attached thereto by means of bracket members Ii attached to the machine and to the end frame. Two of these brackets are provided having along their upper edges guideways extending horizontally and longitudinally of Preferably these guideways may be in the form of rods i 2 held in position by their ends passing through openings within the brackets H. w

Mounted for movement upon these rods i2 is a carriage it having rollers id resting upon the rods i2. As shown in Fig, 1 three of these rollers it are" provided, two upon one side of the carriage l3 and one upon the opposite side. If desired, however, a pair of rollers id may be mounted on each guideway 52. Each roller it may be centrally grooved upon its periphery and provided with an anti-friction bearing for mounting upon outstanding studs E5 on the carriage l3. Bolted or otherwise secured to the carriage i3 is a motor it the armature shaft it of which extends vertically and has secured thereto at its upper end a pulley id. A plate 1d M secured to opposite sides or the carriage l3 as by bolts 20 completely covers and guards the pulley l8. The brackets and the rods |2 are sufficiently long to permit a substantial travel of the carriage l3 along the rods l2 toward and away from the end of the machine upon wheels l4 with minimum friction.

Extending from the carriage l3 longitudinally of and along a portion 01' the machine is an elongated rod or tube 2| one end of which engages over an outwardly extending projection 22 formed on the carriage l3. The opposite or free end of the rod 2| is provided with. screw threads 23 engaged by internal threads formed in a cross arm 24. The cross arm 24 is held against rotation by a recessed depending portion engaging over a rib 25 formed in a bracket 26 secured to one of the intermediate cross frames 21 of the machine. Extending between the end frame 9 and the cross arm 24 are tension springs 28, two of these springs being shown, one on each side of the threaded or tube rod 2|. At one of their ends the springs 28 are attached to the cross arm 24 and at-their opposite ends to small'brackets 29 attached to the end frame 9. The springs 28 are as shown helically wound tension springs normally stretched as shown in Fig. 1 and forcing the rod 2| and carriage l3 toward the right as seen in the drawings.

Extending around the pulley I8 is a belt 30 extending the length of the machine and passing around an idler pulley (not shown) at the opposite end of the machine. Disposed along the machine on opposite sides are spindle brackets 3| secured in properly spaced relation to each other on frame girts 32. Each bracket 31 and its mounting has a spindle 33 the whirl 34 of which presses against a surface of the belt 30 during operation. Asthe spindles 33 and their mountings and operation form no part of the present invention further description of their construction and operation will not be required. As shown in the drawings the spindles 33 are on the outside of the lengths of the belt 30 on each side of the machine and but one spindle on each side is shown. Mounted adjacent-the spindles 33 and bearing against the inner surface of the belt are idlers 35 suitably mounted for rotation in positions to properly support the belt 3|] against the whirls 34. e v

In operation and after the belt 30 has been placed in position upon the machine and around the pulley l8 the rod 2| is rotated by a suitable wrench engaging the hexagon end thereof 38 in a direction to move the cross arm 24 toward the left until the proper compression is exerted upon the rod 2| to give the desired tension to the springs 28. This adjustment forces the carriage l3 toward the right and is constantly exerted. By adjusting the tension in springs 28 by rotation of rod 2| to move the cross arm 24 toward or from the end frame 9, any desired tension may be-imparted to the belt to give the necessary driving effect to the whirls 34.

I claim as my invention:
