DEVICE FOR HARDENING FELT GOODS.

SPECIFICATION forming part of Letters Patent No. 390,094, dated September 25, 1888.

Application filed May 26, 1888. Serial No. 275,128. (No model.)

To all whom it may concern:

Be it known that we, JOHN PENDERGAST, of Boston, in the county of Suffolk, State of Massachusetts, and DANIEL PENDERGAST, of Merrimac, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Devices for Hardening Felt Goods, of which the following isa description sufficiently full, clear, and exact 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 l is a top plan view of our improved device, represented as in position for use, certain portions being represented as broken away; Fig. 2, a side elevation of the same; Fig. 3, a bottom plan view of the pad detached; Fig. 4, a top plan view of the cone or former closed; Fig. 5, a side elevation of the same, represented as partially open; and Fig. 6, a plan view of a bat made on the cone.

Like letters and figures of reference indicate corresponding parts in the difierent figures of the drawings.

Our invention relates to means for hardening felt goods, more especially felt boots, shoes, hats, 850.; and it consists in certain novel featu res, as herei nafter fully set forth and claimed, the object being to produce a more effective and otherwise desirable device of this character than is now in ordinary use.

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

In the drawings, A represents the steamtable; B, the hardening-pad; G, the cone, and D the bat formed on the cone.

The table A consists of a rectangular box provided with a series of perforations, m, in

- its top, through which the steam may pass,

and with a pipe, E, for supplyingit with steam, said pipe being connected with asuitablesteamboiler for that purpose. The top of the table is covered with wire-cloth above the holes m, said cloth being secured thereto by a binding strip and screws, as shown at z, and also by any necessary additional means to keep it in proper position. The body of the pad B is rectangular in form and is of the ordinary size and construction, excepting as hereinafter set forth. Its face or lower side is covered with wire-cloth, G, which is passed upward over its edges and secured by a binding-strip and screws, as shown at 15, although it may be secured in any other suitable manner, if preferred. Jointed at a: to one end of said pad there is a pitman-rod, H, provided at its outer end with a strap, I, which is fitted to work on an eccentric, J, on the driving-shaft K, said shaft carrying a pulley, L, and being journaled in suitable bearings, which in the present instance are supported by the table A.

The body of the cone consists of two main sections, M N, which are hingedtogether at 22. These sections are rectangular in form and perforated, as shown at 9, their forward ends or toes being rounded or curved, as shown at f. They may, however, be made of any suitable size or shape, in accordance with the bat to be formed thereon. Each of said sections is covered with awire-cloth covering, P, the edges of the wire cloth being secured to the sections on their inner faces, so that when the sections are closed the rough edges of the cloth will not be exposed to catch on the bat and interfere with the work. The body of the pad may, however, be made in one piece, if preferred, instead of in sections hinged together, as described, said piece being perforated to permit the steam to pass through it, and covered with wire-cloth in substantially the same manner as shown in Fig. 4.

In the use of our improvement the bat D, having been carded and formed on the cone 0, the cone, with the bat thereon, is placed beneath the pad B, on the table A, and said pad reciprocated by the shaft K in the usual manner, the cone being turned on the table and the bat manipulated as in ordinary machines ofthis character until properly hardened. The felted material of which the bat is composed is pressed into the meshes of the wire-cloth 5 covering of the table, pad, and cone during the process of hardening, thereby enabling these parts to take sufficient hold of or produce sufiicient friction on the bat to felt or hardon it in a much more perfect manner than it ICO can be performed when they are not covered with wire-cloth or a similar reticulated fabric.

The perforations in one or both sections of the cone 0 may be omitted, if desired, and one or more of the parts described as being covered with wire-cloth may have said covering omitted, although I deem it preferable to cover them all, as set forth. The table and cone being perforated and covered with wire-cloth and the pad imperforate and covered with wire-cloth, the action of the steam on the bat is also much more efficacious than it otherwise would he.

Having thus explained our invention, what we claim is- 1. In a device for hardening felt goods, a pad, as B, having its lower side or workingface covered with wire-cloth, as G, in combination with a steam-table and means for reciprocating said pad, substantially as set forth.

2. In a device for hardening felt goods, the steam-table, as A, having a top provided with perforations, as m, and covered or partially c )veied with wire cloth, as F, substantially as described.

3. In a device for hardening felt goods, a cone or former, as 0, covered or partially covered with wire-cloth, as P, substantially as set forth.

4-. In a device for hardening felt goods, a 0

cone or former, as 0, provided with perforations, as g, and covered or partially covered with wire-cloth, as P,substantially asdescribed.

5. In a device for hardening felt goods, a cone or former, as 0, comprising two main sections, as M N, hinged together, one or both of said sections being covered with wire-cloth, as P, substantially as set forth.

6. In a device for hardening felt goods, a cone or former, as 0, comprising two main sec tions, as M N, hinged together, one or both of said sections being perforated, as g, and covcred with wire-cloth, as P, substantially as described.

7. In a device for hardening felt goods, the steam-table A, provided with the perforations m and wire-cloth cover F, the pad B, provided with the wire-cloth cover G, the cone G, having the perforated hinged sections M N, provided with the wire-cloth coverings P, the pitman H, hinged to said pad, and adjunctive mechanism for reciprocating the pad, substantially asset forth.
