JOHN A. MINSHULL, CLF WHITINSYILLE, MASSACHUSETTS, ASSIGNOR 10 WHITIN MACHINE WORKS, 0F WHITINSVILLE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

SPINNING, TWISTING, AND LIKE `IWACHINE` Application filed Jarmanr To @ZZ '1.0 tofr/L` t may concern Be it known that I, JOHN A. MINsI-IULL, a citizen of the United States, residing at lVhitinsville, in the county of Worcester, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Spinning, Twisting, and like VMachines, of which the following is a specification, reference being had therein to the accompanying drawings. Y The invention relates to improvements in foot boards of spinning, twisting and like machines, and the object of the invention is structed this is a tiresome operation espe-f cially to operatives of medium height, and in order to make it easier for the operative a stationary step is arranged on the floor alongside of the` machine, which answers the purpose but has the disadvantage of blocking the working space between two adjacent machines. shown and described herein, I eliminate this objectionable feature by providing a foot board of suitable height from the floor that, when not in use swings up out of the way and when in this position its construction `serves as a guard preventing damage to any of the projecting parts of the spindles and ring rails that might otherwise be bumped and broken by trucks passing` through the space between adjacent machines.`

Referring to the drawings, which illustrate merely by way ofexample a suitable embodiment of my invention; Figure 1 is a perspective view of a well-known type of twisting machine showing my improvement in operative position thereon. Figure 2 is an enlarged sectional end elevation on line 2-2 yof Figure 1, showing my im- In my improvements as 15, 1925. serial No. 21,562.

proved construction in operative position ir. full lines and in dotted lines its inoperative position. Figure 3 is a front `elevation of one of the foot board supporting arms and its hanger. Similar numerals refer to like parts throughout the several views.

In the drawings, 10 and 11 are the head and foot ends respectively of a common type of ring twisting machine, 12 is a stationary rail connecting the two ends together. A plurality of L shaped hangers 13 are bolted to this rail. On the lower end of cach hanger are stationed ears 14; and 15 holding a stud or pivot 16 on which an arm 17 `is swingable. The foot board is held .in its horizontal operative position (see full lilies in Figure 2) by the side of the notch 19 on the arm 17 abutting against the lower end of the` hanger 13. Thestud 16 is provided with an enlarged end 20 serving as a support for a coiled spring 21, one end 22 of which is fastened to the hanger 13 and the other end 23 abuts against the underside of the foot board, the tension of all the springs together being sufficient to swing the foot board out of its operative position, whenever the operative steps from the board, into its inoperative position as shown in dotted lines in Figure 2.

By this `construction when the operative desires to attend to the creel 24 he swings the foot vboard down to a position where he may easily step up onto it and thus be in a' position where he may easily reach the creel without undue exertion. After finishing his attentions' to the creel he steps to the Hoor and the foot board automatically swings into its inoperative position close to the side of the machine out of the way of any operations along the side of the machine.

Underneath the `outer` side of the foot board 18 a rail 25 is fixed which serves to strengthen the board and also acts as a guard to prevent trucks, passing along the side of the machine, from hitting the ring rail 26 and the foot board supporting arms 17.

What I claim is:

1. In a machine of the character specified having a` rail connecting the end frames of the machine, a phirality of hangers in a stationary relation with said rail, a swingable arm pivoted to each hanger, a board a stud supported by each pair of said ears7 an arin swingable on each stud, a board supported by the arms, an abutment on each arm cooperating with the end of its supporting hanger, and a coiled spring mounted lon each stud having` one end iixed to the hanger and the other end abutting against the underside of the arm whereby the resiliency of the springs operate to swing the board from its operative position to its ini operative position against the side of the machine.

In a machine of the character specified having a rail connecting the end frames ot the machine, a. plurality of hangers fixed to said rail, a swingable arm pivoted to each hanger, a board supported by the arms, manually operated means to swing,` the board into a horizontally operative position and means to automatically swing the board from its operative position to an inoperative posi-- tion against the side of the machine.

4. In a machine of the character specified having a rail connecting the end frames oi" the machine, a plurality of hangers fixed 'to said rail, a swingable arm pivoted to cach hanger, a board supported by the arms adapted to assume a horizontal operative position under the influence of the weight ot' the operative, and means to automatically swing the board from its operative position to an inoperative position on the removal oit the weight oi the operative.

In a machine of the character spccilied having a rail connecting the end frames oi the machine, a plurality of hangers in a stationary relation with said rail, a swingable arm pivoted to each hanger, a board supported by the arms adapted to assume a horizontal operative position under the infiuence of the weight ci' the operative, a guard member attached to the underside ot the board and means to automatically swing the board from its operative position to an inoperative position against the side of the machine.

In testimony whereof, I have signed this specilication. Y

JOI-IN A. MIN SI-IULL.
