IMPRovEMBNT IN MACHINERY FORIMAKING cLorEms-Pnvs.V

To all whom it may concern:

Be it known'that I,-A. J. OoKINGToN, of Stratford Hollow, in the county of Coos, and State of New Hampshire, have invented a new and improved Machine for Making Clothes-Pius; and I do hereby declare that the following in a full, clear, and exactidescription thereof, which will enableothers skilledin the art to make and use the'same, reference being had to the accompanyingdrawings, forming. part of this specification.

The object of this invention is to provide a simple and efficient automatic machine for receiving the turned blanks from one or more lathes, |sawing the said blanks, which are long enough for three or more pins, and slot- .ting and delivering thorn, all as hereinafterl specied.

' Figure 1 represents a plan View of my improved machine; i

Figure 2- represents a longitudinal section, taken on the line c: :1; of igQl; e

Figure-3 represents a transverse section, 'taken on the line y y of tig. 1; and

, Fignrel represents .a transverse section, taken on the line z z of fig. ll.

Similar letters of reference indicate corresponding parts.

A represents the frame `of a receiving and sawingapparatus, consisting of 'a hopper, B, or inclined chute,

, a series of grooved carrying-cylinders, saws D, and guides E andF.

This apparatus is designedto beso placed relatively to a tnrninglathe, wherein the blanks G are turned in lengths for three or more pins, so that as the said blanks 'are chopped from ,the lathe` they will fall into the chute B, and roll'down against the faces of the cylinders C, revolving on the shaft C.

These cylindersl have longitudinal grooves, H, so shaped that as each groove passes the mouth of the chute, one of the blanks will fall in and be carried over 4the said cylinders, which brings the blanks against the saws D, on a mandrel parallel with the cylinders.'

ylior sawing the blanks into three pieces, four saws will be used, one at each outer end ofthe outer cylinders, and one in each of the spaces between the cylinders. these saws the bl'anksare cut into the proper lengths for the pins as they are carried over by the cylinder from the hopper to the carrier I, the said blanks being held in the grooves by the' guides'E and F.

The said carrier I consists of an endlessb'elt, Working-over wheels'K and L, and along a trough, M.

AIt convcysthe blank pins from the sawing-apparatus,-delirering them to a carrying-wheel, N, which takes themI up, one at a time, by means of two hooked fingers, O, projecting from one side of the said wheel, near the face, over which ingers the ends of theblanks are presented, and a spring-actuated wedging-inger, P, working laterally through the wheel, and arranged to www...

spring forward over the blank atthe moment the hooked fingers arrive under the said blank. l

These spring-fingers slide in suitable supports in the gear-wheel S, which operates the wheel N, and are forced forward by the springs R, after being disengaged from a curved spiral guide, T, which engages with notches V,'to draw the said spring-fingers back 5 to discharge the pins, and hold them in the retracted posit-ion until the proper time for securing the blanks.

The blanks, so engaged, are` carried up bythe wheel N and presented-to a saw, WV, which slots them, as shown at x, tig. 4, after which they are discharged by the Withdrawal of the spring-finger I, as above stated, and a discharger, P. i

'Any number of these sets of hooked and spring-fingers may be arranged on' the wheel N, according to its size and speed relatively to that of the carrier I.

A stop, Y, is provided inside of the ngers, to arrest the blanks at the right point.

The carrier is designed to be run at such a speedthat all ,the blanks delivered at once from the carryingcylinder C will be moved but of the way before a succeeding delivery.

It may also be so arranged as to'receive similar dey lliveries from another receiving and cutting-apparatus,

1. The combination of the inclined hopper'B, re-4 cessed blank-holder and transferrer G, and guide E, arranged as described, so that the first Vwill feed the blanks by gravity to the second, which shall transfer andl'hold them to the saw, as set forth.

2. 'lhe carrier-wheel N,provided with the hooked fingers 0 and'sliding spring-lingers P, combined with the carrier I, and arranged to presentithe blanks to a saw, W, all substantially as specified.

3. The combination of rotating-wheel N, provided with spring-holding ngers P, as shown, with the4 perforated gear S, 'spring- R, and spiral guide T, all arl ranged and operating together, as described.
