WASHING MACHINE.

i Application lccl July 22, 1925. Serial No. 45,386.

The present invention relates to washing vmachines and especially to washing machines of the suction cup or pounder type.

In connection with such washing machines, it is desirable to mount the bells or cups on the yoke so that they are yieldable in a vertical direction. To accomplish this, it is usual to provide a spring mounting for the bells or cups.

An object of my invention is to provide an improved spring mounting for the bells or cups of a pounder type washing machine which, while serving efficiently its intended function, is simple in structure and capable of being manufactured and assembled at a low cost.

A further object of my invention is to provide an improved construction wherein the means which holds the spring mounting assembled serves also to fasten the suction cup or bell to its stem.

A 'further object of my invention is to provide an improved construction wherein there are no openings through the top of the yoke whereby the yoke is left perfectly smooth on its top surface and presents no parts upon which clothes are likely to catch.

For a consideration of what I believe to be novel and lmy invention, rected to the accompanying description and the claims appended thereto. l

In the drawing, Fig. 1 is a side elevation, partly in section, of a structure embodying my invention; Fig. 2 is a detail sectional view of a spring mounting, the Vsection being taken at a right angle to that of Fig. 1, and Fig. 3 is a sectional view of a modification. 1

Referring to the drawing, 1 indicates the plunger rod of a pounder or suction cup type washing'machine and 2 indicates the yoke which is mounted on the plunger rod and carries the suction cups or bells at the ends of its arms 3. The washing machine mechanism for actuating the lplunger rod may be of any suitable type. For example,

Y it .may be of the vtype or construction shown in my Patent No. 1,520,886, dated December 30, 1924. The yoke may comprise'any suitable number of arms 3, for example, three arms or two arms. It is preferably adjustably mounted on the plunger rod, being held by a spring-pressed pin 4 adapted to engage in any one of a number of openings attention is di- 5 in the upper end of the plunger rod. The head of the pin which enters openings 5 is indicated at 6 and the spring for holding the pin is indicated at 7.

At the end of each yokee arm is a downwardly-facing socket 8 which is closed at the top by a smooth wall 9. lVall 9 is rounded so as to present a pleasing appearance and leave no sharp corners upon which Y clothes might catch. In the wall of socket 8 is a transverse opening 10 in which is located a pin 11, the pin fitting they opening with a drive fit. In socket 8 is a tubular stem 12 having a vertically-elongated slot 13 through it, through which pin 11 passes, the stem being thus hung on the pin. On the lower end of stem 12 is a dished collar or flange 14 against which the suction cup or bell 15 is held. The lower end of tubular stem 12 is threadedy and screwing into it from below is a plug 16 having a flange 17 which engages the suction cup or bell 15 and serves to attach it to stem 12. Dished collar or flange 14has a radius of curvature less than that of the'bell or suction cup Vso that when plug 16 is screwed up to fasten bell 15 to collar 14, the bell, will be pulled tightly into Aengagement with the flange at the edge of the flange. This gives a tight connection between the two parts and serves to hold the bell from turning. `As an additional means for holding the bell from turning, I may provide a depression 18 in collar 14 into which a raised portion 19 in the bell fits.

Located in tubular stem 12 between the in ner end of plug 16 and pin 11 is a spring 2O which is held under compression by the plug. Between the upper end of the spring and pin 11 is arranged a disk 21 having a conical projection 22 on its upper surface which lits in a groove 23 surrounding pin 11. This disk serves as a lock for pin 11 to prevent the pin from coming out. It serves also as a seat for the upper end of the spring. In flange 17 of plug 16 are suitable openings 24 to receive a wrench for screwing the plug into place.

With the above-described arrangement, it will be seen that the entire structure is held assembled by the flanged plug 16 and that nok separate fastening means is required for attaching -bell 16 to stem 12. This means that the structure can be quickly and easily Cil assembled and that no special skill or special tools are required tor the operation. Also, as will be noted, the structure comprises a minimum number of parts.

1n assembling the structure, stein 12 is inserted into socket 8 and pin 11 is then driven tnrough opening 10 and slot 13. Following this disk 21 is dropped into stein 12 followed by spring 20. Bell 15 is then placed in position in dishe'd flange 141 and plug screwed into place. The screwing ot the plug into place serves to tasten the entire structure together and to put spring 2O under the desired degree of compression,

.ln Fig. is shown a modification where- -in pin 11n corresponding te pin 11 ot Figs. 1 and 2l-is threaded on its inner end as is indicated a-t 25 and screws into an opening in arm El. lll/lith this arranc'enient the pin is held by fthe screw threads so that a locking disk such as the disk 21 oit Figs. 1 and 2 need not be used. Otherwise, the arrangeinent ot 3 is the saine as that or" Figs. 1 and n..

Spring 20 is held under the desired coinpression by plug 16 and serves normally to `hold the suction cup from vertical movement. llt/Then the upward pressure on the suction cup is excessive, however, the spring yields to permit stem 12 to move upward in socket 8, -t-lie spring being compressed against ipin 11. Slot 13 is ot a length to permit ot the desired amount ot axial movement ot stein 12 in socket 8.

ln accordance with the provisions of the patent statutes, 1 have described the principle -ot operation otliny invention, together with the apparatus which 1 now consider to represent the -best embodiment thereof, but I desire to have it understood ythat the apparatus shown is only illustrative and that the invention may be carried out by other means.

liVhat l claim as new and desire to secure by Letters Patent or the United States, is:-`

1. lln a suction cup washing machine, a `nieniber 'having a. socket open at its lower end, a tubular stein projecting into said socket, said stem having an elongated slot in its wall, a pin which extends through the wall ot sai-d socket and through said slot, a pliiig in the lower end ot' the stem, a spring located between said plug and pin, said tubular stem having aninternal diameter such `that the spring may be inserted trom the outer end of the stein, and a suction cup carried by the stein. n
