T0 @ZZ zul/00711, it vit/ty concern:

Be it known that I, ISAAC E. PALMER, a citi- Zen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Machine for Extracting Liquid from Fabric, of which the following is a specification.

My invention relates to a machine for extracting liquid from fabric, and more particularly to means for utilizing centrifugal force in connection with the wringing of a rope of fabric to free the fabric from liquid.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a top plan view of the machine. Fig. 2 isa longitudinal vertical section in the plane of the line A A of Fig'. 1, and Fig. 3 is a transverse section in the plane of the line B -B of Fig. 2.

The bed of the machine is denoted by 1. It may be supported in any suitable manner-as, for example, upon legs 2.

From the bed 1 standards 3 and 1 uprise, and in the said standards 3 and a bearing's 5 and 6 are formed for the reception of the hollow trunnions T and 8 of what I am pleased to term the "centrifugal frame. This centrifugal frame is composed of a pair of side plates 9 and 10, fixed to or formed integral with the trunnions 7 and 8 and held spaced apart to receive between them the rollers for guiding therope of fabric through the frame. ln the present form of my invention l use four of these rollers, two of them (denoted, respectively, by 11 and 12) being journaled in the upper and lower parts of the centrifugal frame in vertical alinement and another two (denoted, respectively,by 13 and 14) being mounted in the opposite ends of a vibrating frame 15, mounted, by means of trunnions 16 17, extending' outwardly from the opposite sides of the frame, between the sides 9 and 10 of the centrifugal frame. The vibrating frame is made in open-loop form, so as to permit the rope of fabric to pass between its opposite sides, and the rollers 13 1&1, carried by the vibrating' frame, are in such position as to hold the rope of fabric in proximity to the rollers 11 12, journaled in the centrifugal frame, and, fur- (No model.)

thermore, as the result of the centrifugal force of the centrifugal frame when rotated at a high speed the rollers 13 and 14 will have a tendency to move away from the axis of rotation of the centrifugal frame, and this will cause the vibrating f rame carried by the centrifugal frame to rock in a .direction to press the rollers 13 and 14 toward the rollers 12 and 11, respectively, and so squeeze the rope of fabric passing between them. This squeezing' force may be increased, if desired, by a spring so arranged as to normally rock the vibrating-frame to press the rollers 13 14 toward the rollers 12 and 11, respectively. Such a spring is indicated in Fig. 2 as a bar-spring 18, fixed at one end at 19 to the inner face of one of the sides of the centrifugal frame and with its free end pressing on the side of the vibrating' frame. It is to be understood that this spring is a feature which may 0r may not be used, according to the pressure required in any particular instance, as only one of many obvious forms of applying spring-pressure to the vibrating frame.

The centrifugal frame is rotated by means `of a band-pulley 20 on the extended end of the trunnions 8, driven from a suitable source of power. (Not shown.)

The rope of fabric (denoted by 21) is fed to the centrifugal frame from a series of gripping-rollers, three in number, (denoted by 22 23 24,) mounted in a suitable frame 25, upris- Y ing from the bed 1 at one end thereof, and is drawn from the centrifugal frame by a corresponding set of gripping-rollers 26 27 28, mounted in a suitable frame 29 at the opposite end of the bed 1. In the form in which my invention is here presented the rollers at the discharge end are relied upon to draw the fabric through the machine, although it is obvious that the rollers at the opposite end might be power-driven, if so desired. The fabric after passing' between the inlet-rollers in the form of a flat strip passes through the hollow trunnions 8 and thence under and partially around the roller 14: in one end of the vibrating frame 15, thence between the roller 21 and the roller 11 up, over, and around the roller 11 and down between the sides of the vibrating' frame 15 under and around the roller Y twisting the fabric intermediate of said grip- 12, thence between the roller 12 and the roller 13 and over and partially around the roller 13, and thence through the hollow trunnion 7 to the discharge-rollers.

The centrifugal frame driven at ahigh speed of rotation while the rope of fabric is being drawn through produces a tight twist and wringing effect upon the rope of fabric in proximity to the rollers at the inlet end and throughout that portion of the rope of fabric between the inlet-rollers and the centrifugal frame, and this twist is taken out as the rope of fabric leaves the centrifugal frame and passes through the hollow trunnion 7 to the discharge-rollers.

The rope of fabric in passing through the centrifugal frame is carried a considerable distance radially away from the axis of rotation of the centrifugal frame in opposite difirections from the axis, and so is brought under the influence of a powerful centrifugal force because of the high rotation of the centrifugal frame, which has a tendency to throw the liquid away from the rope of fabric andremove all free liquid from the fabric. This centrifugal action follows closely upon the wringing effect produced by the twist of the fabric as it approaches the centrifugal frame, so that all liquid which is wrung to the surface will be thrown off. i

lVhat I claim is- 1. The combination with means for gripping a rope of fabric at points spaced apart and causing the said rope of fabric to pass through the said gripping devices, a rotary part for ping-points and means for guiding the fabric laterally away from the axis of rotation of the said rotary part as it passes through said gripping devices.

' 2. The combination with inlet-rolls and outlet-rolls for conducting a rope of fabric, of a said rotary part while engaged with said rotary part.

3. rlhe combination with inlet and? outlet rolls, for conducting a rope of fabric, of a rotary frame provided with hollow trunnions rotary frame located intermediate of said gripping-points and provided with hollow trunnions, of rollers mounted in said frame radially distant from the axis of rotation of the said frame," a vibrating frame mounted in said rotary frame, rollers mounted in said vibrating frame and means for directing a rope of fabric through the said rotary frame in engagement with the aforesaid rollers.

5. The combination with means for gripping a rope of fabric at points spaced apart and a rotary frame located intermediate of said gripping-points and provided with rollers located radially distant from its axis of rotation, of a vibrating frame mounted in said rotary frame in position to rockin a plane of the axis of rotation, rollers mounted in the opposite ends of said vibrating frame and means for directinga rope of fabric into engagement with the said rollers between the said rollers mounted in the rotary frame and the rollers mounted in the Vibrating frame whereby the rocking of the vibrating frame under centrifugal force of rotation of the rotary frame will squeeze the fabric between the rollers.

Intestimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this lst day of January,

ISAAC E. PALMER. Witnesses:

CHAs. M. SAUER, FRANK P. HAYDEN.
