PRESSING DEVICE.

. Application filed May 16, 1923. Serial No. 639,257.

To all who-m it may concern;

Be it known that I, BENJAMIN D. GoLnnuns, a citizen ofthe United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in ressing Devices, of which the following is a specification.

"My invention relates to pressboards or pressing devices designed for use in pressing fabrics or clothing and so. Constructed as to afforda supporting surface having a large number of fine metal teeth or points upon which the fabric is sustained during the operation.

' In devices of this nature it has been customary to employ what is known asoard clothing comprising numerous bent pieces of hard drawn wire called dents or teeth which are fixed in a suitable foundation consisting usually of several layers of cloth or textile fabric cemented together to form a good supporting body, the whole comprising substantially a wire brush the individual teeth or" dents of which are very close together over the Whole surface and form a great number of points or needles that afford a support to the fabric when subjected tothe action of the pressing iron.

This form of card or brush is subject to several objections among which may be mentioned that when a hot/iron in conjunction with moisture is applied in the pressing operation, the steam developed by the hot iron condenses on the foundation and the wire itself becomes oxidized, thereby destroying the device. Furthermore the heat softens the cement of the cloth foundation, thus permitting the position of the wires to be disturbed, and also the heat may cause them to lose their temper and permit them to bend under the pressure, thereby destroying the efliciency of the entire device.

The object of my present invention is to avoid the objections-and disadvantages incident to the ordinary construction of card clothing and to make it possible to dispense with the employment of any cloth or textile material in the device whatever.

My present invention consists in constructing the card or brush upon which the fabric is sustained in the pressing operation from a multiplicity of thin strips or plates of metal each formed on one edge with a line of closely spaced points or teeth, said plates of any desired number being assembled and held in position side by side in a close mass, all forming in co-operation, by their points or teeth, a surface for the pressing device of any desired area consisting entirely of closely arranged metal points or teeth over the entire surface, acting in the same manner as the teeth or dents of the usual card clothing.

In carrying out my invention the said teeth or points are preferably formed in a conical shape so as to afford a widened base for the point itself, thereby strengthening the same against turning or denting under the pressure; The individual plates themselves may be each formed with a number of depressions in a side thereof for the purpose of affording passages through the mass of plates for condensed moisture or for the passage of a supply of steam or moisture upward through the body of plates. In effect my device is madeof solid metal and incapable of absorbing moisture. Being of metal, however, it is adapted to become heated in the process of pressing and any moisture collected in the device will be turned into steam or vapor thus increasing the elliciency of the device and avoiding rusting. Inasmuch as the bodies of the plates or strips are in firm-side conta t with one another and form together I. s solid, metal body, and the teeth themselves have enlarged bases, it is obvious that my present device will be extremely strong and will not give or dent upon the application of the pressing iron since there is no cloth cemented foundation. Furthermore, inasmuch as my present device is made wholly of metal, it is extremely sanitary.

My invention further consists'in details of construction more particularly pointed out in connection with the accompanying drawings and specified in the claims.

In the accompanying drawings:

Fig. 1 is ageneral view of a steam or similar pressing board for pressing fabrics provided with a pressing device constructed in accordance with my invention. In this figure the fine points are indicated at one end of the top surface or area, said points being repeated inpractice, of course, over the whole supporting area on the upper surface of the pressboard here shown as an elongated board with rounded ends.

Fig. 2 is a plan of the base upon which the assembly of metal strips is supported, said strips or plates being removed.

Fig. Bis a cross-section on the line 33 of Fig. 2. v

Fig. 4 is a side elevation of one of the strips. Y Fig. 5 is a bottom edge view thereof. Fig. 6 is a vertical cross-section through one of the strips upon the lineof one of the points.

Fig. 7 shows the device .in plan with .a portion of the assembly of strlps in place. Fig. 8 is aperspective view of the bottom side of a mass. of .the strips enlarged in size. l'indicates an individual thin metal strip or plate formed in proper shape for producing, by assembly with a number of others, a pressing device embodying my invention. Referring to Fig. 4:, the individual points or teeth of each strip are indicated at 2. These aresformed inv oneedge of the plate or strip and may bemultiplied toany desired number in each strip and are each of substantial conical form as shown in the Fig. 4; and in the Fig. 6 which is a vertical section through one of the points. This shape of point or tooth, by affording an enlarged base for the point, adds strength to the device. Also in a side of each strip I prefer to form vertical grooves or depressions indicated at 3, the number=of which may also be multiplied as desired.- When the plates are assembledin close side contact with one another, these. grooves or depressions form in efl'ect perforations in a metal body made up of the plates or strips and afford passageways for moisture or steam.

4 indicates a metal base-upon which the strips are supported on edge and towhich they are locked or secured in any desired manner. j Preferably I provide in each strip a notch indicatedat 5 which constitutes, when the plates are assembled as shownin Fig. 8, a groove running crosswise of the strips solidlyassembled together in contact and operating as the groove or mortise for ways or guides 6 on the upper surface of the base .4 (Figs. 2 and 7). These ways or guides are formed as tenons co-operating with the grooves 5 ofthe massed assembly of plates thereby locking the-assemblage of plates in position against detachment from the base. Any other means might be employed, however, for holding the assembled plates down upon a suitable base plate.

In the base plate are provided any suitable or desired number of openings or passageways 7 which permitthe passage of steam or vapor through the base plateand through the fine passages in. the-mass of toothed plates or strips-aiforded by the grooves or depressions 3 therein.

To assist .in firmly holding the plates upright in position and preventing their .displacement, the base plate 4 may be provided with a flange 9 bounding the assemblage of plates or strips. At one end of the assembly of strips the portion 9 of the flange may be made detachable and suitable clamping screws or other clamping means employed to press the same against the end plate or strip of the assembly, thus pressing them firmly together in solid contact wit-hone another.

A hollow support for the device having a vapor or steam connection is indicated at 10 while: the connection is. indicated at 11. Evidently steam, supplied through 11 and the hollow support 10 is -free to pass up through the openings in the based and through the passageways in the solid mass of strips. 1 1

As will be seen, the base 10 for the fabric support proper mountedthereon provides a steam space underneath the whole fabric support from which steam 'issupplied through all portionsof: the fabric support for passage therethrough tothe fabric being pressed. F

The device may be used eitherv under or over the clothbeing pressed or maybe ap plied both under and over. i
