GEORGE ASH-EPARD, OF BETHEL, CONNECTICUT.

Letters Patent No. 102,722, (lated May 3, 1 870.

IMPROVEMENT IN'MACHINES FOR COVERING- REEDS FOR HAT-TRIMMINGS.

The Schedule referred to in these Letters Patent and making part of the same.

It consists in the arrangement in the machine of y an endless feed-apron, folding or curling-gauge, re-Y volving cutters, and pressers that act upon the cemented material; and

It further consists in the giving the proper press-V ure upon the cemented material that covers the reed without crushing or in any way Ainjuring the reed in passing through the machine.

Figure l is a perspective view of a machine einbodying my invention;

Figure 2 is a front view of the cutters, with the other parts removed;

Figure 3 is a side view of the cutters, showing the groove in the lower cutter for the reed;

Figure 4 shows a reed, placed near the edge of a cemented piece of cloth, with 'a portion of the cloth turned over the reed, as it is done by passing through the curling-gauge in front of the cutters;

Figure 5 is a cross-section of the covered reed; and Figure 6 is a side view of the same. A is the frame of the machine. B is the crank by which the shaft C is made to turn.

C' is a shaft over the shaft C, and is made to turn by the motion ofthe shaft C through the gears D D.

E and E are revolving cutters` centrally placed around revolving shafts C and C'.

The cutter E is turned down to form the recess o, and receive therein the outer edge of cutter E', as seen in figs. 2 and.

Each ofthe cutters has cutting-edges, a. c, upon the angles of contact. A

The cutter E' revolves in and upon the upper snrface of recess o in cutter' E.

The sides of the cutters are purposely turned a litt-le under, in order that their cutting-edges a' a may always be in contact and sure to out the luaterial.

Thevedge of E', at 11, which comes over groove c in the recess o ot' cutter E, is turned od slightly, so as to give room for the reed being covered to pass through without being pressedany more than to closely fold the cemented material around it.

The lower cut-ter E (not seen iu iig. 1) is fastened to and turned by the shaft C, and the cutter E is fastened correspondingly to the shaftA C.

F is a lpulley on the outer end of the sha-ft C, and when in motion gives a corresponding motion to the `pulleys AIWF", and to the rollers H H', to which the pulleys F F" arehstenedby and'with the belt a.

I- is an endless apron, strained over the rollers H H", and moving in connection with them.

K is a piece of material, (cloth or leather, as may be, cemented on the upper side, so that when the edge is folded cver and pressed together it will rmly adhere.

misa reed, such as used in hattrimming, laid at 'the proper distance from the edge of the cloth K to be folded in as itpasses through the foldinggauge N, and by which thecloth K is turned over it, asseen in fig. 4.

c is a groove turned iu the cutter-head G to receive the reed m, soas to allow the cloth K to be pressed firmly together between the cutter-rollers E E as it passes through.

fis a spring ou t-he shaft C', by which the`cuttingface and edge of the revolving cutter E are kept firmly against the corresponding face and edge of the cutter E, thus forming rotary or revolving shears to cut oit' the covered reed from the material as itpasses' through.

Ath is a spring, by which the cutter E is made to press firmly, though not rigidly, against the cutter E, causing the cemented surfaces to adhere to each other as they pass between t-he pressing-surfaces ofthe cutters E E'.

N is a folding or curling-gang@iliade 'from sheetmetal, of such shape and form as that, when the material K and the reed m are forced through it, the material will be folded overthe reed and back upon itself to or nearly to the line cut by the revolving cutters E and E.

It will be seen that, when the'cemented cloth K is put on the revolving 'apron I, the reed 'm being properly placed, by the mot-ion given to the apron I by .the rollers H H', the pulleys F F F and the belt c from vthe crank B, through the shaft C, the cloth K will be carried forward through the curlinggauge N, folding the edge of the cloth K over the reed m, as shown in iig. 4, and through between the cutting and pressing-rollers E E', thus turning out thecovered reed ready for use.

The cloth K is now drawn back, readj usted, another reed put on, and the process repeated as often as desired.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the'rcvolving endless apron I,

folding-gauge N, and revolving and pressing-cutters El and E',` when the several parts are constructed and arranged to operate in the manner'and for the purpose above described.

2. lhe spring h over shaft C, in combination with the revolving and pressing-cutter-E and cutter E, having recess o and groove c, all arranged to operate in the manner substantially as and for the purposes set forth.
