SPECIFI UAltION forming part of Letters Patent No. 6 10, 141, dated January 2, 1900. Application filed October 3, 1898. Serial No. 692,498. No model.)

To ail whom it may concern:

Be it known that 1, WILLIAM T. BRADLEY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Vringers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its objects to improve the construction and operation of clOthesWringers, particularly that class in which the pressure between the rollers is caused by spring action; and to these ends it consists in certain improvements in construc tion and combinations of parts, all as will be hereinafter described and the novel features pointed out particularly in the claims at the end of this specification.

In the drawings, Figure 1 is a perspective view of a wringer constructed in accordance with my invention; Fig. 2, a vertical sectional view of the same; Fig. 3, a sectional view on the line a" x of Fig. 2; Fig. 4, a view showing one of the guard-plates.

Similar reference-nu merals indicate similar parts.

The main frame of the wringer embodies two side members or brackets 1, containing the bearings for the rollers and connected by the plate or web 2, which latteris engaged between the ribs 3 on the members 1 and secured by the screws 4 passing through said plate and also through perforated lugs 5 on the members and serving as the pivots of the swinging clan1pingarms 6. The arms 6 are provided with clamping-screws 7, which cooperate with the downward extensions 8 on the side frames or members to clamp and hold the machine upon a tub or other suitable support, and the independent swinging motion of the clamps enables the machine to be atached to tubs having various diameters.

The rollers employed are of the usual construction, being covered with rubber, and when in use their surfaces are in contact, their arbors 9 resting in half bearing-blocks 10 and 11, preferably of wood, and as each of the side frames or members is open at the front the rollers maybe inserted and removed without separating said frames. The bearing-blocks 10 for the lower roller are arranged in recesses or sockets formed in the body of the members 1, and the blocks 11 of the upper roller are arranged in sockets in the ends of journal-boxes 12, having cylindrical extensions 13 operating in recesses 14, formed in the members 1 directly over the lower blocks 10.

15 indicates springs arranged in the recesses 1st and operating to press the boxes down and to hold the rollers in contact, the approach of said rollers being limited by adjusting rods or screws 16, passing loosely through the frame and preferably screwing into the tops of the boxes, so that by drawing the boxes upward against the tension of the springs the machine may be arranged for operating on heavy goods, or the rollers may be kept in very light contact, just sufficient to hold them in place when not in use. The rods or screws 16 may be rotated for the purpose of adjusting the rollers by the springs; but I prefer to secure a more rapid adjust ment by a cam action, and for this reason-provide the screws with enlarged heads 30, fitting in recesses in the ends of levers 31 and having the transverse pins 32 extending through cam-slots 33, formed in the sides of said levers, as shown. The cam-slots are so arranged relative to the handles or operating ends of the levers that when the latter are in the position shown in full lines in the drawings the rollers are in contact under springpressure; but when the levers are raised the screws are moved upward and the pressure is entirely removed from the rollers. This arrangement not only facilitates the construction of the parts, buta rapid adjustment may be had by moving the cam-levers, or the screws may be rotated in the boxes, the lower surface of the levers then resting on the top of the frame 1. If desired, the screws 16 could be made rigid relative to the boxes or bearings l2 and the cams alone employed to adjust the latter.

17 indicates guard-plates arranged at the ends of the rollers to prevent the contact of the goods with the frame, said plates having apertures 18 for the passage of the arbors of the rollers and the inwardly-turned flanges 19. One of the apertures 18 in each guardplate is elongated somewhat to permit of the relative adjustment of the rollers, and when in position the outer sides of the plates are against the journal-boxes of the upper roller to prevent longitudinal movement of the rollers.

The parts of the machineframe are very few and simple, only two bolts being required to fasten the parts together, and all said parts are castings which can be easily and cheaply made. Furthermore, the rollers can be easily removed and inserted when desired by moving the upper half-bearings vertically by the adjusting -.screws until the journals of the upper roller are released and then withdraw ing the rollers through the open fronts of the main frame.

I claim as my invention 1. In a wringer, the combination with the main frame composed of the side frames having the bearings thereon, the flanges and lugs, the connecting web or plate extending between the frames and engaging the flanges, and the bolts passing through the lugs and plate, of the clamp-arms pivoted on the bolts, and the rollers journaled in the bearings in the frames.

2. In a wringer, the combination with the main frame embodying the side members, each open at the front and having the stationarybearings and the recesses above them, of the movable journal-boxes, the separate springs located in the recesses and engaging the movable journal-boxes, the rods engaging the movable journalboxes and extending through the upper portion of the frame, adjustable'means operable from the upper portion of the frame for limiting the movement of the boxes caused by the springs, and the rollers.

3. In a wringer, the combination with the main frame embodying the side members open at the front, having the downward extensions, and the stationary bearings, the connecting web, and the bolts connecting the members and web, of the clamp-arms pivoted on the bolts, the movable journal-boxes, the springs for operating them, adjusting devices for limiting the movement of the boxes, and the rollers.

4. In a wringer, the combination with the main frame embodying the side members open at the front, having the sockets, the stationary bearing-blocks therein, and the recesses over them, of the movable journal-boxes guided to move in the recesses, the springs arranged in said recesses, the screws engaging the boxes, and the rollers.

5. In a wringer, the combination with the main frame embodying the side members open at the front, and having the recesses 14, and the stationary bearings beneath, of the journal-boxes 12 having the extensions operating in the recesses 14, the springs in said recesses, means for adjusting the journal-boxes independently against the tension of the springs, and the rollei-s.

6. In a wringer, the combination with the main frame embodying the side members open at the front, and having the recesses 14, and the sockets beneath, and the removable bearing-blocks therein, of the journal-boxes .12 having the extensions operating in the recesses 14, and the bearing-blocks 11 therein, the springs, means for adjusting the journalboXes independently against the tension of the springs, and the rollers.

7. In a wringer, the combination with the main frame, the stationary roller, the adj ustable roller, and the journal-boxes for the lat ter, of the rods connected to said boxes having the pins, and the levers having the camslots in which said pins operate.

8. In a wringer, the combination with the main frame, the stationary roller, the adjustable roller, and the journal-boxes for the latter, of the threaded rods screwing into the boxes, and the cam-levers connected to the upper ends of the rods and engaging the frame.

9. I11 a wringer, the combination with the main frame, the stationary roller, the adj ustable roller, and the journal-boxes for the latter, of the threaded rods screwing into the boxes, having the heads and the pins there on, and the levers having the cam-slots engaging the pins, and also engaging the main frame.
