IMPROVEMENT IN MACHINES FOR COVERING REEDS FOR HAT-TRIMMINGS.

I Specification forming part of Letters Patent No. 102,722, dated May 3, 1870}. reissue No. 6,782, dated December 7, 1875 application filed February 8, 1875.

for Hat-Trimmings, of which the following isa specification:

The object of this invention is to coverrodsof whalebone, wire, or other material, technt cally known as reeds, used in trimming hats with prepared cloth, leather, or other material, or-attaching the same by machinery, at a single operation.

The invention consists, first, in the combination of a folding-gage, a lower revolving presser or roller, and an upper revolving presser or roller, formed on the projecting end of a revolving shaft, so as to enable the material to be folded to be introduced from'one side between the revolving pressers without regard to its width or length, and so as to permit the easy inspection and regulation of the operation of the revolving pressers when at vwork; second, in the combination of a folding-gage with a revolving presser formed on the projecting end of a revolving shaft, rotating against a second revolving presser,

formed with a flange or guide revolving withit behind the pressing-surfaces, to regulate the width of the material to be passed between the surfaces, and prevent its escaping through beyond them; third, in the combination of an endless feed-apron, a folding-gage, and revolving pressers formed with cuttingedges, as hereinafter described; fourth, in the combination of a folding-gage witha revolvingpresser formed on the projecting end of a revolving shaft, and a second revolving presser, having a groove in its pressingsurface, to admit of the passage of the reed over which the covering material is folded, the object of this part of the invention being to give the proper pressure upon the cemented material folded around the reed, without pressing or crushing the latter out of shape or position; fifth, the combination of a revolving presser, formed on the projecting end of a revolving shaft, having a cutting-edge at the outer end of its pressing-surface, with a second revolving presser, having a raised cutting edge or flange on the outer end of its pressing-surface,

so that the two cutting-edges correspond, and

may be brought into constant contact, and a spiral spring on the upper revolving shaft, by

which the cutting-edges maybe. firmly pressed togethe'r, so as to operateat the point of con tact lik-e'revolving shears.- l

"In the drawing, Figure 1 is a perspective view of a machine embodying myinvention. Fig. 2 is'a section of the upper revolving disk and lower roller,-upon whichare formed the pressers or pressing-surfaces a b. Fig. 3 is a side view of the same, showing the pressing surfaces, the groove for thereed, and the guide-flange attached to the lowerpresser in rear of the pressing-surfaces, for regulating the width of the material which ispassed through between them and its compression around the reed and the cutting-edges, in contact on the side of the pressing-surfaces opposite the groove and guide-flange.

Ais the frame of the machine. B is a crank, by which the: shaft C is made to turn. C is a shaft over the shaft 0, and is made to turn by the motion of the shaft C through the gears D 1). E and E are the revolving disk and roller, formed or placed on and concentric with the revolving shafts C and C, and constructed so that their pressing-surfaces a and b revolve with equal velocity, and are turned in opposite directions by the shafts C C. The roller E has n flange, 0, on the outer side of its pressing-surlace, on the upper and inward circumference of which is a cutting-edge, a, and on the outer circumference of the disk E is also a cutting-edge, a, both the end of the disk E and the flange 0 being turned a little under. 1* is a pulley on the outer end of the shaft- C, and when in motion gives a corresponding motion to the pulleys F F" and to the rollers H H, to which the pulleys F F are fastened by means of the belt 61. I is an Fig. 4' shows a piece of the covering, material,1' artl y--- turned over and upon the-reed, as; is donejbyf passing it through the" curlinggageset in front of the revolving .pressers.) Fig. 5 is: a'

endless apron strained over the rollers H H, and moving with them. K is a piece of mate rial covered on its upper side with adhesive substance, so that when folded over and pressed together it will tirmly adhere. a-reed, such as may be used in hat-trimming, laid at the proper distance from the edge of the material, which is to be folded over it and pressed down. N is a folding or curling gage, made of such shape and form that when the material K and reed m are passed through it the material will be folded over, the reed to the proper distance, and it is so placed with reference to the revolving pressers that the material so folded over the reed shall pass directly between the pressers, the reed and material directly about it following in the groove 0 and against the guide G. The flange or guide G is formed on the lower revolving roller E, and projects past the place of contact of the pressing-surfaces a. and 11,111 what ever positiou they maybe, and acts as a gage to regulate'the-width of material which may be introduced between'the pressers from the other side, and prevents its escaping from between the presser-surfaces. The groovecis formed in one side'of the roller E, next to the gage G,and the corresponding edge of the disk E is turned off somewhat, so that the material may be firmlypressed around the reed as it passes through or over the groove without crushing the reed or injuring the material. h is a spring, by which the disk E is made td' press firmly though not rigidly against the pressing-surface a, to cause the adhesive material .to adhere as it passes between the surfaces. f is aispring on the shaft 0, by which the cutting-edge a of the disk E may be kept firmlyagainst the cutting-edge a of the range 0', thus forming rotary shears to out on the: material at the line of contact as it passes through and this action of the spring f in the directionof the axes of theshafts is necessary to the complete actiouof the cutting-edges, for if itdoes not operate the mate rial will pass by between the'pressers without being cut. 7

When the machine is in operation for coverin g reeds, a strip of prepared material is the proper distance from the inner edge, and both the material and the reed are carried by the apron through the folding-gage and between the pressing-surfaces, so that the reed follows through the groove and against the gage, and the turnededge of the material is pressed closely down by the pressing-surfaces, and adheres firmly, and at the same time the strip of material containing the reed so covered is cut off at the proper width, and the covered reed is turned out ready for use. 7

It will be seen that when the material is introduced in front of the pressing-surfaces a b, the guide-flange Gr operates not only to prevent the material from escaping in the rear of the pressers, but also as a gage to regulate the width of the material pressed and of the strip out oh, and, in conjunction with the groove 0 and turned-off edge b of the disk E, to compress the material neatly about the reed and make an even finish. It will also be seen that the operation may be repeated as often as desired by bringing the material again along on the apron and passing it through the folding-gage and other parts in the same manner and the construction of the disk E upon the end of the shaft, with its pressingsurface revolving upon the pressing-surface of the roller below, issuch that the material can be conveniently manipulated about it, and easily inspected and adjusted during the operation, and the work is done without compressing or injuring the material beyond the line of contact of the cutting-edges.

The sheet of adhesive material passing over the horizontal apron of the machine as the folding and pressing of its edge proceeds,

and being attached to its edge, which is folded Zand pressed substantially until the instant it :passes between the pressing-surfaces, serves to regulate the operation of the folding device, and the width of folded material passing between the pressing-surfaces to be pressed with the utmost nicety, and enables the operator to leave a greater or less selvage edge of one thickness of material upon the side of the covered reed by causing the folding-gage to turn over the edge of the material to a greater or less width upon its surface and this action of the sheet of adhesive material upon its edge to be folded over, and the oper-' ation of folding and pressing it with accuracy, are only rendered possible by the pressingsurface of the disk E being formed upon the proj ecting end of its shaft outside of the shaft-' bearings, so as to permit the sheet of adhe-' *sive material to be introduced from the open side of the pressing surfaces and remain attached to its edge, which is folded over sub stantially until the fold passes between thepressing-surfaces, while the sheet of adhesive material continues to progress in the same plane as before, past the end of the disk E under the control of the operator, and without itself passing between pressing-surfaces. placed on the endless apron, with the reed at What I claim as new and my invention is l.
