IMPRCVEMENT IN MACHINES FOR TURNING HANDS AFOR SHOES.

The Schedule referred to in these I-ters Patent and making part of the same.

To all whom it may concern:l

Be it known that I, HoRAon H. BIGELow,of the city and county of Worcester and State of Massachusetts, have invented certain new and useful'lmprovements in Machines for Turning Bands; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing which forms a part of this specification, in which- Figure 1 represents a ont view'of my improved randturning machine;

Figure 2 represents a plan view of the same;

Figure 3 represents an end view; and

Figure 4 represents a longitudinal vertical section through the center of the operating-shaft. To enablethose skilled in the art to which my invention belongs to make and-fuse the same, I will proceed to describe it more in detail.

The nature of my invention consists in certain imeach side above the bearing O, thereby forming cheek plates, F, between which a movable bearing, G, for supporting the shaft H, is arranged, to which the tops of the cheek-plates F are joined by means of a capplate, I, in the manner shown in the drawing.

J J indicate spur-gears, by which the shafts E and H are connected for operation.

The bearing-piece G is provided with lugs G at each end, which extend downward and fit the upper side of the shafts E, thereby preventing the shafts from being pressed too near each other.

The cap Ov', for holding the lmain shaft E upon its bearing C, is formed short enough to t between the lugs G', and it is secured in position by set-screws K,

arranged through the check-plates'F.

A strong spring, L, of rubber or other suitable material, is arranged upon the top of the bearing G within alrecess formed in the cap-plate I, and a set-screw, M,

for governing the pressure of the spring upon the bear` ing, is arranged through the projection I upon the top of the cap-piece I. f

A pressing-cam, N, is secured upon the outer end ofthe top shaft H for pressing the rand between ythe forming-cams or jaws P P', one of which is fixed to the endvo'f the main shaft E, and thev other yto the end of a rod, O, which extends through the center of the main shaft H, the latter' being formed hollow for its reception.

The forming-earns- P P are made inthe shape re- P P closely together for compressing the rand.

v The pressing-cam N is made of the proper shape to match thecams P P', so that when the shafts H and E are revolved the cams will roll together with an equal pressure throughout the whole revolution. The i cam N is recessed out at one side, so as to facilitate entering and removing the rand.

A bar, R, is secured-to the front-of the machine, Awhich is provided with two backward-projecting studs or pins c, which form a guide for the `rand as itisA` drawn into the machine. A driving-pulley, S, is arranged .loosely upon themain shaft E, and the hub S thereof is furnished with' clutch-teeth upon one of its ends which engage with asimilar tooth upon the clutch-ring` T when'the latter is moved up against the pulley-hubs.

The" clutch-ring is secured to the centerv spindle O by means of a pin, c, which passes through the parts from side to side. v

A longitudinal slot is formed in the shaft E, through which the pin c' passes, thus permitting the actionof lthe .ring and .center spindle in a directionl parallel to Atheir axis independently of the main shafd;

The clutch-ring T is provided withaprojecting'lug, V, which runs against a beveled starting-lever, W, and forces forward the ring to release the clutch from the teeth on the pulley-hub ST1 The starting-lever W is made in bell-crank form, and is fulcrumed at its heel between projecting earpieces f f ou the bed-plate B, while the rear arm thereof, W', is connected by a rod or strap,-X, to'some suitable operating treadle beneath the table upon which the machineA stands.

A spring, Y, is attached to the starting-lever W for the purpose of drawing its upper beveled end forward against the pulley-hub S', upon which is formed a suitable shoulder to guide and steady' the end of said lever.

The clutch-ring T, center rod O, and forming-cam P work in concert, and are moved to` the right by the spring Q, and to the left by the llug V and beveled 'starting-lever W.

The operation of my improved rand-turning machine is as follows:

The operator passes the end of the rand upward` between' the guidestuds c and rest-s it against the spur a,. he then places his foot upon the treadle-and depresses the'rcar arm-W', which swings hack the itarting-lever W and releases the lug'Y and clutchring T, when the' springQ throws the center rod O :o the right, which closes the cam P against the rand ind moves the clutch-ring T up to the end of the hub S', so that their teeth engage, and the-pulley S, being .n motion, causes the shafts E H and cams I P' and N to revolve. The cam N runs upon the top'of the rand and forces it down between the forming-cams? P', which press it into the desired form.

When the shaft E has made one revolution the lug V runs onto thev beveled end of Vthelstarting-lever, whereby the ring T and center rod O are carried to the' le far enough to disengage the clutch-teeth and thus stop the motion of the shaft,'and also to separate the cams or jaws l? P', so as to release the-rand, which is then remov'ed from the machnetumed to the proper form. s l Y l Having described my improved machine for-turning rands, l

What Iclam' therein as new and of my invention, and desire to secure by Letters Patent, is-' 1. The'combination, with the formngcams or jaws P P', of the pressing-cam N, substantially as and for the purposes set forth. Y

2; The combination, with the shafts E and H, 'of the center rod O, forming-cams or jaws l? P', pressingcam N, and spring Q, substantially as and for the purpose set forth. t

3. The combination, with the shafts E and H, center rodO, and cams N P P,of. the bearing-piece G` G', spriugL, and adjusting-screw M, substantially as and for the purposes set forth. N.

4. The combination, with the sha: E and rod O, of the clutch-ring T, starting-lever W, and 'sprin g Q, sub-` stantially as and for the purposes set forth. y

5. The combination, with the cams or jaws P P",",of

"` the bar R, provided with guide-pins c, substantially as and for the purposes set forth.

6. The combination, with the cams or jaws P Pv', of f the holding stud or point a, substantially as and for the purposes set forth.
