Specication of Letters Patent No. 15,634, dated `.August 26, 185.6- *dw To all whom t may concern Be it known that we, l/VILLIAM `Fosxii'r and `,BENJAMIN S. STEDMAN, of Meriden, 1n the county of N ewiHaven and State of Connecticut, have invented a new and useful Machine for `Sizing Comb-Blanks or other Articles; and we do hereby declare that the following is a full, tion of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l, is. an elevation of the machine, partly in section. Fig. 2, is a plan of the same.

Similar letters of reference indicate corresponding parts in the two figures.

In the blanks are generally out of as great a length as the material admits of, and in a large number there will be a great variety ot lengths and many will be so nearly of the same length that it will be ditticult to detect any dit'erence without comparing them closely side by side.

It is desirable in putting the combs up in packages of dozens or more or less to have all the combs in one package of the same size exactly, and as the only way of sorting them in sizes heretofore employed has been to pick them out by hand which has been a slow and tedious operation and has required great practice to acquire any degree of skill in the process. This machine is intended to perform the operation of sizing, .as it is termed, with great exactness and dispatch.

Themachine may be in different forms, but the form represented in the drawing will serve to illustrate the principle of the invention as well as any other.

A, is a metal table supported by a. stand upon a base C, and surrounded by a circular metal frameD, which is shown in section in Fig. l. The edge o, a, of the table is made in the form of a. spiral, gradually ree ceding from the center to which center the frame D, is truly concentric. The spira-l form of the edge of the table leaves a taper slit or opening E, between the table A and the frame D, and this should be so proportioned in width thatthe width of the narrowest extremity e, of the opening should be a trifle less than the length ofy the shortest blanks, and the width of the widest end e', a tritle greater than the length of the longest blanks. The ends e, e, of the opening E, do

Y not quite meet and unite, but the `tab clear, and exact descripi to `the rabbet f.

manufacture of ivory combs, the

tended at part to meet theframe o form a resting' place o, `for the blanks to be 'laid .on for introduction to the machine.

Thetable is beveled all around forsome '60 distance inward `from its edge, as `shown at el, d, Fig. 1, and the inner portion of the top of the fra-me D, has a rabbet f, turned in it, the `angle of the said rabbet occupying such a position that it would be met by a straight line continued from the bevel d, CZ as will be understood by reference to `the right hand side of Fig. l, where a comb blank is shown striding across the opening E, from the table F, F, are 'series of boxesor compartments arranged below the opening E.

G, G, G, are arms tted to turn on the center pin t. Of these arms there may be as many, attached to one hub, as can be ineluded in the circumference of the table, leaving spaces between them fully suliicient to admit the width of the comb blanks, said arms fitting down to the bevel d d, of the table and extending all or nearly all across the opening E.

The operation of the machine is as follows A continuous rotary motion at a moderate speed in the direction of the arrow shown in Fig. 1, is given to the arms G, G, G, by any convenient means and an attendant who occupies a position near the resting place c, takes up the blanks g, indiscriminately from a heap and places them one by one upon the resting place c, with the length of the blank running toward and from the center b, as

`fast as the arms G, G, severally pass the said resting place. The resting place o, has the same inclination as the bevel b, of the table, which is suliicient to cause the blank to descend by gravitation till its lower end is arrested by finding the bottom of the rabbet f. The arms, in passing the resting place, sweep the blanks oit it and push them along partly supported by the rabbet F and partly by lapping over the edge of a,

ot.' the table, moving them from the narrowest toward the widest end of the opening E, until, in passingover the gradually receding edge a, they, sooner or later, accordingas they are shorter or longer, reach a point where they are no longer supported by the edge of the table and fall through the opening E, into the box or lcompartment below. j This s illustrated in Fig. 1, where, on the "1;10

left side of the machine, a blank g, is shown over the narrowest portion of the opening, where it receives support for a considerable portion of its length, from the table, but on the other side of the machine the same blank is shown as having arrived at a point where the 'edge a, has receded so far from the frame D, as no longer to support the upper end of the blank which drops down `and the whole blank falls bodily through the opening.

By making the table of large size so as to make room for a very large number of compartments or boxes F, F, the sorting may be effected with such nicety that no diierence can be detected by the eye on a comparison between the blanks Jfalling into any one box. But, by making a long table and frame of similar character to A and D, but of an oblong form With rounded ends, and attaching the arms G, G, to an endless belt or chain running around two pulleys on upright shafts a large machine can be brought into less space than if made of the circular form shown; as an instance of this, We will state that a machine on that plan, constructed by us, contains over three hundred compartments F, F, While the diierence be tween the longest and shortest blanks sized upon it seldom exceeds one inch and a half.

It may be remarked, that instead of having the beveled and gradually receding edge a on a table inside the rabbet f, the position of the parts may be reversed by making the rabbet on the central table and the beveled and receding edge on the frame D, but the 'former arrangement is preferable.

What we claim as our invention and desire to secure by Letters Patent, is

The gradually-receding edge a, arranged within or around and inclining toward a rabbet f, so as to Jform a tapering opening E, between them, with a resting place c, at the narrowest end of the opening, when combined with a set of arms G, Gr, rotating or otherwise moving over the opening and with boxes, compartments or other .receptacles below, to operate substantially as and fo the purpose herein set forth.
