MACHINE FOR SPONGING CLOTH.

SPECIFICATION forming part of Letters Patent No. 516,945, dated March 20, 1894.

Application filed January 28, 1893. Serial No. 460,000- (No model.) Patented in Austria-Hungary May .19, 1892, 110.26.144;

in France November 14, 1892,110. 225,682, and in England December 14, 1892, No. 24,156.

To all whom it may concern.-

Be it known that I, THEODOR SARFERT, a subject of the King of Saxony, and a resident of Chemnitz, Saxony, German Empire, have invented certain new and useful Improvements in Machines for sponging Cloth, (for which patents have been granted in England, No. 24,156, dated December 14, 1892; in France, No. 225,632, dated November 14, 1892, and in Austria-Hungary, No. 26,144, dated May 19, 1892,) of which the following is a specification.

This invention relates to certain improvements in cloth finishing machines, and has for its object to provide a device of this character which shall be simple and inexpensive in construction, effective in operation and which shall obviate certain defects attendant on other forms of such machines heretofore employed, all as will be hereinafter fully set forth.

The novel features of my invention will be carefully defined in the claims;

In the accompanying drawings which serve to illustrate my invention-Figure 1 is a general front elevation of a machine constructed according to my invention and Fig.2 is a side elevation of the same. Fig. 3 is a detail sectional view of the steaming cylinder and Fig. 4 is a corresponding view of a modified form thereof which will be referred to hereinafter. Fig. 5 is a cross section of the steaming or sponging roll detached with its surrounding parts.

In the views A represents a frame of suitable form and strength, in which is journaled a cross shaft '1'.

O is a counter shaft bearing the usual tight and loose pulleys n m, together with a friction wheel 0, the periphery of which is in engagement with a second friction disk or wheel 0 mounted on a vertical shaft Q, the upper end of which shaft is provided with a bevel gear q, engaging with a bevel gear (1 on the machine shaft 1", as clearly seen. Mounted on the frame above shaft r and driven therefrom by means of gears r, r is a second shaft e, on which is mounted the steaming cylinder or roll (1.

Around the roll a, are arranged at suitable points a number of light rollers 6', e f, f',f f three of which are adjustably mounted in movable bearings as clearly shown, said bearings being arranged in guide-ways and adapted to be adjusted by means of screws 8, 8', collared in the frame as clearly seen in the drawin gs. Over these rollers passes an endless covering cloth or apron 't, which also passes 7 about the sponging or steaming roll a, being reversed over the upper rollers e 6 as clearly seen in Fig. 5. This covering cloth is composed by preference of felt or other suitably close and impermeable fabric, and serves to prevent too ready passing of the steam through the cloth, as well as to hold the cloth strained on the sponging roll in order to prevent shrinkage. The cloth to be finished passes from a reel w, over a tension device composed of the transverse rods Z, Z, over the rollers h, 71/, down over the roller 6, between the covering cloth t and the periphery of the roll a, around said roll where it is steamed or sponged, up over the roller e and finally onto the roller or reel 70. Between the rollers e, 6 is arranged a light roller d, which may be heated in order to dry the cloth and to smooth the same after the operation of sponging has been performed. The roll a is composed of an outer perforated drum and an inner cor rugated imperforate cylinder b, both of which are fixed on shaft e and receive and discharge steam through ports e e suitably formed in said shaft. The outer drum or is supplied with steam for sponging through an inlet tube- 62X (see Fig. 3) which opens into the interior of cylinder 1) the ends of which 'are open as clearly seen, said cylinder being mounted on spiders on shaft 6 whereby its ends remain open. Thus it will be seen that the steam for sponging the cloth passes out through the open ends of the corrugated and imperforate cylinder 17 and passing through the perforations in drum a reaches the cloth.

In order to prevent the formation of water stains, &c., in the cloth due to the falling thereon of water of condensation from the steam in the sponging roll, I have provided the cylinder b with inturned flanges 2' at its opposite ends whereby any water which might fall from the inlet tube 6 will be caughtand held within said cylinder 1) and in order to prevent the accumulation of such water in said cylinder, I have provided a steam coil 0,

arranged in said cylinder b and receiving a supply of superheated steam through ports in shaft 6, whereby such water of condensation as may fall into said cylinder will be vaporized by the heat from said coil as will be read ily understood.

In the form of sponging roll illustrated in Fig. 4,1119 construction is substantially the same, except that the coil 0 is doubled and receives and discharges steam through ports formed in one end of shaft e, while at the other end of said shaft are formed ports for the admission and discharge of steam to and from the interior of said cylinder 1) to efiect the Sponging.

The advantages of my improved finishing machine over other constructions hereinbefore devised are obvious. As stated,the formation of water stains due to water of condensation falling from the sponging roll onto the cloth is prevented and by the provision of the endless covering cloth or apron t, the said cloth is prevented from shrinking While under treatment,being held securely between said cloth and the drum.

Having thus described my invention, I claim- 1. In a cloth finishing machine, the c0mbination with a shaft, of a sponging roller consisting of an outer perforated drum and an 30 der having open ends provided with inturned o flanges, an inlet pipe having its mouth arranged within said inner cylinder and adapted to supply the steam for sponging, and a steam coil, arranged in said inner cylinder around the mouth of said inlet pipe and 45 adapted to contain superheated steam substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

THEODOR SARFERT.
