CLOTH ES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 651,217, dated June '5, 1900.

Application filed $eptember 2, 1899. Serial No. 729,376. (No model.)

vented a new and Improved Clothes-Wringer,

of which the following is a specification.

This invention relates to improvements in that class of clothes-wringers known as ironframe wringers, having horseshoe spring members that form supports for the journals of the rolls and which have their spring tension adapted to hold the rolls normally to a tight compressing position.

Primarily this invention seeks to provide certain improvements embodying a very simple, economical, and compact arrangement of parts capable of being easily manipulated and which will eifectively serve for the intended purpose.

Another and essential feature of myinvention lies in a novel construction of means for conveniently adjusting the tension of the spring ends of the horseshoe members, whereby their spring pressure can be quickly adjusted to permit the rolls being used for wringing differentkinds of material, including the wringing of dampening-cloths, such as are commonly employed for letter=press copying.

Again, my invention includes a novel means for supporting the spring members, and in its subordinate features it comprehends certain details of construction and peculiar combination of parts, all of which will be hereinafter fully described, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my improved iron-frame Wringer. Fig. 2 is an end elevation of the same. tion taken on the line3 3 of Fig. 2. Fig. 4; is a similar View taken on the line 4 4 of Fig. 3.

Referring now to the accompanying drawings by numerals, and in which like numerals designate like parts in all the figures, it will be noticed my improved wringer comprises end frames 1 1, which may be cast metal, and their lower ends terminate in tub or bench clamps 2, which may be of any ordinary construction. The castings l are preferably made with an upwardly-extending member 1*, which has a guide-slot 1 for the hub por- Fig. 3 is a detail sec tion 3 of the rolls 3, which may be of anyapproved construction. The frames 1 are each provided with a forwardly-extending wing 1, having outwardly-extending horizontal brackets 4, in which the devices that hold and support the U-shaped springs 5 are held. The U shaped or horseshoe springs have the tensionof the ends 5 normally pressing toward each other, and each of the ends terminates in ball-bearin gs 6 to receive the journals of the rolls 8. The springs 5 are held in a substantially-fixed position by the springtension-adjusting means, which comprises a pair of opposing right and left threaded shanks 8, each of which has a collar or flange 8 near its outer end and a projecting nonthreaded portion 8*. The ends 8 in practice pass through apertures 8 in the spring members, which are normally held to bear tightly down on the flanges S, and by reason of their free ends being supported on the roller-journals and the ends 8 of the shanks said horseshoe-springs will have a fixed position and yet be capable of free adjustment.

9 indicates a turn-nut having opposite right and left threaded sockets 9 to receive the threaded ends of the shanks. Thus by having the threads in the nut 9 in different directions the tension of the horseshoe=spring can be governed at will. The shanks 8, it will be noticed, pass through non-threaded apertures in the brackets 4, which, together with the compressible action of the ends of the springs, serves to hold the adjusting means firmly in proper position.

By supporting the springs in the manner shown and providing the double screw shank and nut device it is manifest the tension of adjustably mounted on the end supports,

said springsnpports including means for simultaneously and uniformly spreading the free ends of the springs as set forth.

2. The combination with the end supports, said supports having outwardly-projected apertnred brackets; a right and left threaded turn-nut interposed between the said brackets; right and left threaded screw-shanks, engaging the nut and pointed in opposite directions through the apertn red brackets; the rolls and the horseshoe-springs supported-by the said shanks, said springs having hearings at the ends to receive the journals of the rolls, all being arranged substantially as shown and described.

3. The combination with the end supports, said supports having clamp members and provided with extensions 1, said extensions havingoutwardly-projected horizontal apertnred flanges; the turn-nut 9; the threaded shanks 8, said shanks having collars S, and extensions 8 the horseshoe-springs having the opposing membersdetachably held on the extensions 8 of the shanks; spring-arms having bearings provided with bearing-balls; and the rolls, said rolls having their journals engaging the ball-bearings in the ends of the arms as specified.

4. The combination with the end hearings 1, having slotted extensions; the rolls 3, having hub portions 3, guided in the slots of said extensions; said end hearings having an extension 1, formed Witha pair of outwardlyprojecting horizontal flanges 4 4; the turnnnt 9; the shanks 8, having collars 8; and the horseshoe-springs having their arms detachably held by the shanks, and having end hearings to receive the journals of the rolls, all being arranged substantially as shown and described.
