CONE OR FORMER FO R FELT-HARD ENING MACHINES.

SPECIFICATION forming part of Letters Patent No. 404,362, dated May 28, 1889.

Application filed December 26, 1888. Serial No. 294,618. (No model.)

To all whom it may concern.-

Be it known that we, JOHN PENDERGAsT, of Boston, in the county of Suffolk, State of Mass sachusetts, and DANIEL PENDERG-AST, of Merrimae, in the county of Essex, State of Massachusetts, have invented acertain new and useful Improvement in Cones or Formers for Felt- Hardening Machines, of which the following is a description sufficiently full, clear, and exact IO to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a top plan view of our improved former; Figs. 2 and 3, sectional views illustrating details of construction, and Figs. 4 and 5 like views showing a modification of the improvement.

Like letters of reference indicate corrcsponding parts in the different figures of the drawings.

Our invention relates to cones or formers employed on machines for hardening felt goods, as boots, shoes, hats, &c.; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a more effective device of this character than is now in ordinary use.

0 The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

The former A consists of a flat body com- 3 5 posed entirely of wire-cloth f. It may be tapered or curved at one end, as shown in Fig. 1, or constructed in other shapes suitable for the character of the goods being manufactured. The edge of the cloth is bound at z to prevent the ends of the wires from catching in the felt and rendering it difficult to remove the former from the bat. The binding .2 may consist of a strip of metal secured to the ends of the body and filling wires of the cloth, or said ends may be soldered together, the latter method being preferable, as the binding thus constructed is practically of equal thickness with the body of the former, rendering its operation on the bat more effective. We prefer to employ galvanized wire-cloth, as the cone thus formed is much stiffer and more readily handled, the Wires being thusseeured firmly together, as shown in Figs. 2 and 3.

To obtain additional rigidity, we sometimes use two sheets of wire-cloth, placed one above '5 5 the other, as shown in Figs. 4 and 5, and secured together by a metallic binding-strip,'m.

It will readily be seen that when the bat is folded or formc d onto our improved former and manipulated upon the steam-table in the usual manner the felt comprising the bat will be forced into the opening between the wires of the cloth, or the ribs or corrugations of the cloth will penetrate into the felt and prevent the bat from slipping on the former.

The action of the steam upon the bat is also more thorough than is ordinarily the case, as the former offers slight resistance to its passage.

The action of the heat and moisture upon the Wooden formers in ordinary use frequently causes them to become misshapen and practically useless-an objection which is obviated by our improvement.

Having thus explained our invention, what we claim is 1. A former for shaping a completed wool bat during the hardening process, consisting of a flat body composed entirely of wirecloth, substantially as set forth. 8o

2. A former for shaping a completed wool bat during the hardening process, consisting of a flat body composed of two sheets of wirecloth and a metallic binding-strip uniting, said sheets at their edges, substantially as set 8 5 forth.
