Patented Au 6, 1940 V UNITED STATES PATENT OFFICE SPINDLE MOUNTING Connecticut Application May 11, 1940, Serial No. 334;,865 4 Claims. This invention relates to'a mounting for a spindle or other unit, a plurality .of which are to be driven from a single belt traveling about the machine. One of the objects of the invention is to provide an exceedingly simple and yet positively acting resilient hinge mounting which cannot get out of order. 7 Another object of the invention is to provide an adjustment whereby the spring tension which moves the spindle toward the belt may be adjusted that the desired pressure upon the drive belt may be had. The invention consists specifically in the provision of a single-leaf spring through which all action is provided with an adjustable mounting for such spring. With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. In the accompanying drawing: Fig. 1 is a side elevation of the spindle mounting showing in section a portion of the framework to which it is clamped; Fig. 2 is a section on line 22 of Fig. 1; Fig. 3 is a side elevation looking toward the driving belt from the side thereof on which the mounting is positioned; Fig. 4 is a section on line 4-4 of Fig. 3; Fig. 5 is an exploded perspective view of the hinge connection between two relatively movable members. In spinning or twisting machines in which a 5 single traveling belt is utilized for driving a plurality of spindles with the whorl of each blade resiliently urged into contact with the traveling belt for actuation of the blade in order that an extremely simple mounting of the spindle may be had, I have arranged a resilient hinge con-- nection whereby the spindle mounting is flexibly connected to a bracket so that when the mounting is swung to flex its hinge, the inherent resiliency of the hinge itself tends to return the mounting to a predetermined normal position; consequently, by setting the spindle into engagement with .the belt to such an extent that the hinge is flexed, the hinge will continuously tend to swing the spindle mounting into engagement with the belt; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished: With reference to the drawing, Ill designates a portion of the frame upon which a plurality of spindles of the machine are to be mounted. The traveling belt against which the whorl of the blade is to contact is designated A bracket, designated generally I2, is held in position upon 5 the frame III by means of a jaw l3, a bolt I4 ho1ding this jaw l3 against the frame and the frame against the portion I 5 of the bracket to bind the bracket onto the frame, the same being adjustable as to position by means of set screws. l6 and 10 I! engaging the framework for tilting the bracket as desired. The bracket has an arm I8 which has a hub l9 having a socket 20 with a segmental opening 2| extending thereto. The other member 22 of the mounting consists 16 of a body part provided with some suitable opening for mounting a spindle 23. The spindle consists generally of a blade 24 having a whorl 25 mounted thereon, although the particular type of spindle is not a part of this invention. This 20 member 22 also has a hub 26 with a socket 21 and an opening 28 extending outwardly from 'the circular socket 21. The member 22 and the bracket member 2 are connected together by a hinge device, shown more 25 particularly in Fig. 5, which consists of a piece of spring steel 30 which has secured thereto cylindrical knuckles 3|, 3|, which are illustrated as being bent up from sheet stock about a center core 32 with clamping jaws 33 and 34 to be riv- 30 eted to the flexible sheet stock 30 through openings 35 and 36 provided therefor along the length of the sheet metal hinge 30. This hinge thus formed is located in the sockets 21 of the hub 26 of one member where it is fixed against rotation 35 and in the socket 20 in the hub IQ of the other member so as to provide a flexible hinge connection between the parts. A set screw 31 serves to adjustably hold the knuckle 3| in adjusted position in the socket 20 allowing it some latitude of 40 adjustment by reason of the segmental slot 2|. In use I will position the spindle bracket on the frame and swing the knuckle 3| in the socket 20 until the whorl engages the belt II with the desired amount of pressure and then I will set up 45 the screw 31 to hold the spring hinge connection in this position. Normally, the spring would be maintained in a single plane, as illustrated in Fig. 4, and thus a bending of the spring as illustrated in Fig. 2 places the same under tension, and as the spring is by its inherent resiliency always tending to return to this straight line position, the whorl engages the belt with a certain desired pressure to 55 maintain a running contact of the spindle with the belt. If more pressure is desired, it is simply necessary to swing the knuckle in the socket 20 to a further declination, or if less pressure is desired, the opposite adjustment can be accomplished. This arrangement enables a very simple construction of the parts to be had and a very simple adjustment. No lubrication is necessary, and no wear upon this hinge connection is apparent. The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible. I claim: 1. In a spindle mounting, a pair oi members, one of said members being provided with means to support a spindle, and the other of said members being provided with means to fix the same on a suitable portion of the framework, and a flexible element of a resilient sheet of material connecting said members for hingedly relating said members and causing them to return to a definite relation if flexed therefrom. 2. In a spindle mounting, a pair of members, one of said members being provided with means to support a spindle, and the other of said members being provided with means to fix the same on a suitable portion of a framework, and a flexible element of a resilient sheet of spring steel connecting said members for hingedly relating said members and causing them to return to a deflnite relation if flexed therefrom. 3. In a spindle mounting, a pair of members, one of said members being provided with means to support a spindle, and the other of said members being provided with means to fix the same on a suitable portion of a framework, a flexible element of a resilient sheet of material connecting said members for hingedly relating said members and causing them to return to a definite relation if flexed therefrom, and means to adjustably connect said element to one of said members that its normal plane may be changed with relation thereto. 4. In a spinning or twisting frame, a belt against which a plurality of spindle whorls contact to be driven, a spindle mounting comprising a pair of members, one of said members being provided with means to support a spindle, the other of said members being provided with means for fixing the same on a suitable portion of a framework, and a flexible element of a resilient sheet of material connecting said members for hingedly relating said members, said members being positioned to flex the element and cause the spindle to resiliently contact said belt to be driven thereby.
