Letters Patent No. 110,700, dated January l3, 1871.

IMPROVEMENT IN ALARM-ATTAcHMENTs Fon MACHINES Fon EoRMlNe HAT-comes.

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

drawing forming part of this specification, and in whichp Figure l represents a plan of my invention as applied to a hat-body machine employing a double conical former, or such portions of a machine of said description as is necessary to explain the operation of my improved attachment; v

Figure 2 is a side elevation of tbe'j'same; and

Figure 3, a vertical section, taken transversely through the center of the conical former.

Similar letters of reference indicate corresponding parts.

My invention relates to hat-body machines which employ a double or reverse conical foriner, arranged to occupy a horizont-al position on or over a lower series of simple conical rollers, between whichand the former the bat passes as it is fed to and is laid on the former, the whole being carried by a swinging crane or frame, as usual in such machines, for the proper laye ing ot' the bat. 1n machines of this description, it

vhas been usual heretofore to gauge the thickness' or amount of lap of the bat on the former, necessary for my given thickness of hat-body, by the eye, or as practice otherwise enabled the operator by his judgment to determine. This requires skill, and is attendant with considerable uncertainty or want of accuracy; and v My invention consists in a certain automatic means or alarm-attachment to a hat-body machine for notifying the operator of the su'icient feed or supply of the bat to the former, to produce a hat-body of any required thickness, and whereby every provision is made for the adjustment of said attachment and for its automatic accommodation to any interruption of 'the operating surface by division of the bat on the cone, and a simple construction, generally, of such attachment obtained.

Referring to the accompanying drawing A represents the double or reverse conical former, with the usual center groove, b, in it, for division of the bat by means of a pair of scissors or other suita.

ble cutter or cutters;

B B are the lower single conical rollers; and

D, the swinging frame of the machine.

This frame is formed with a slotted extension, D', on the back or oi side of the former, along which is adjustable, toward or from the former, by means of an adjusting-screw, E, a block or standard, F, that serves -to carry both the bell G ofthe alarm-attachment and an operatinglever or hammer, H, together with its spring c, so that the whole are adjustable in common by the sliding of the standard F, which forms also the box for the regulating-screw E to work in.l

The object of this adjustment is to provide for the f sounding of the signal or alarm when the bat has been laid on the former A to any desired thickness, according to the thickness of hat-body required, the

hammer H being operated, to strike the bell, by a freely-revolving roller, I, made to face 'both cones of 'the former, and which may be the converse of the latter, and is driven by the friction ot' the bat as it is fed from `the carding-cngine onto the former, said roller being provided with an y number of teeth, d, for

operating the hammer H, when thebat reaches the requisite thickness on the former.

To provide' for the proper working of this roller l,

and to'insure for it a selfaccommodating action to the bat, both generally and when the bat is divided at the groove b, and the one-half or portion .of it forming one hat-body is removed in advance of the other, said roller is loosely hung, so as to be capable of a universal motion, as it were, the same being freely suspended,

by its trunnious e c, in loose link-bars J which arefreely and independently pivoted, as at ff, to acrossbar, K, that is adjustable alongvthe slotted extension D to time7 the action of the roller I on the hammer of the bell, and, in conjunction with the screw E, to effect a most perfect adj ustment of the operating. roller and bell, not only relatively to each other, but also to the former. v

This supple suspensionof the roller l, that is operated by its weight resting on the revolving former or` lied'.

2. The combination of the bell Gr and hammer H with the sliding block or standard F, the adjusting-g screw E, and the operating-roller I, essentially as and for the purpose,herein set forth. y
