SOAP-CAKE RETAINER.

Application filed July 21, 1919.

To all whom it may concern:

Be it known that I, TEMPLE HERBERT COL- BURN, a citizen of the United States, residing at Minneapolis, in the county of Henriepin and State of Minnesota, have invented certain new and useful Improvements in Soap-Cake Retainers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

hIy invention relates to retainers for cakes of soap and has for its primary object to provide such a retainer that can be easily applied to a molded cakeoi soap and thereafter locked to prevent its removal there-Q scribed and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

iReferring to the drawings Figure 1 is a perspective view of the in-, vention. yieldingly suspended from a wall bracket and supporting a cake of soap over a lavatory;

Fig. 2 is a'fragmentary view principally in section of theinvention applied to a cake Fig. 3 is a side elevation ofthe cake of soap suspended by means of the 1mproved retainer;

Fig. 4 is a side elevation of the cakeot soap and showinglthe method of applying the anchor shankthereto;

Figs. 5 to 8, inclusive, are detail views in perspective, with the exception of 8, which a sectional view, of the severalumts of the retainer separated in their relative,

relation to each other; 7 V i Fig. 9 is a perspective view of the nut- .blockand lock-pawlremoved from the cap Fig. 10 is a horizontal section taken on Fig. 11 is a view. of the cap in vertical seetion and'showing the eye-forming wire applied thereto and before the same is bent into form; and" r Specification of Letters Patent.

2 shown, mounted in a casing 18 suspended by three converging chains 19 swiveled to an eye 20 interlocked with the hook 1G. The parts thus far described have been illustrated simply for the purpose of showing one means for supporting the improved retainer.

The improved retainer comprises an anchor shank 21, a gasket 22, a lock-washer 23, nut-block 24 permanently mounted in a cap 25 in the form of a bell having an apertured upper end in which is swiveled an eye 26 attached by a snap 27 to the chain 1 In some instances, it might be desirable, as at public lavatories, to permanently. connect the eye 26 to the chain 17, so that the soap could not be stolen. The shank 21 has on one of its ends, to wit the upper, a relatively fine screw-thread 28. The lower end portion of the shank 21 is folded onto the body thereof and twisted therearound to form a relatively coarse left-hand screw-thread 29.

The body of the shank 21, at the junction of the lower end, is formed flat, as at 30, to receive the prongs of a screw-driver or other tool 31 by which the shank 21 may be turned to screw the same in a cake of soap.

The "gasket 22 is preferably formed from rubber and has an enlarged central aperture 32 to receive the screw-threaded end 28 of the shank 21. and it also has two diametrically opposite relatively small apertures 33 to receive a pair of depending anchor pins 34'on the under side of the lock-washer 23v On the upper face of, the washer 23 and concentric with the axial opening therein, is a multiplicity of cireumierentially spaced ratchet teeth 35. The cap 25 is adapted to be adjustably secured to the screw threaded end ,28 of the shank 21 by means of the nut-block 24, which has screw-threaded engagement therewith. To prevent, the cap '25 from being unscrewed from the shank 21, there isprovided for cooperation with the ratchet teeth 35 a pawl 36, formed on the end of a spring 37 which normally rests upon the upper face of the nut-block 24,'and is secured thereto by a rivet 38. The pawl 36 projects through a segmental slot 39 formed in the nut-block24" for cooperation with the ratchet teeth 35.

Thenut-bl'ock 24 is permanently and rigidly secured to and within the cap 25'by pressserted from the bottom of'the cap 25through an aperture in the upper end thereof and its head 41 locks said wire to the cap with freedom for swivel movement. After the wire'has been inserted through the aper 1 In applying the improved retainer to I cake of soap 44,.the screw-threaded end 28 tured upper end of the cap 25, thesame is bent to form the eye 26. To prevent water from getting into the cap 25 through {the apertu-red end thereof, a disk 42: is pressed into said cap and against an annular shoulder 43 formed therein just below the swiveled end of the eye 26.

of the shank 21 is pressed into thelower end of the soap cake as far as it willgO,

and then the said shank may be turned byapplying the screw-driver 31 to the lower end 30 thereof- By means of the screwdriver 31,the shank 21 maybe screwed into the soap a distance suflicient to project its screw-threaded end 28 through the upper end. of the cake of soap and to carry its lower end 30 entirely within said cake of soap,as shown in Fig. 4... The screw-driver 31 may then be removed and the lowerend of the hole in the soap formed by screwing the shank 21 therein, closed or sealed by'the soap removed during the. process ofscrewa mg the shank 21 therein.- The purposeofthus sealing the lower end of the cakeof soap is to prevent water from getting there-v 1n and softening the soap around the shank 21 so that it will pull out of the soap cake.

The next step in applying the retainer to the cake of soap is to place the washer-like gasket 22 over the projecting end of the shank 21.. The lock-washer 23 is next placed on the shank with the pointed ends of its anchor pins '34 positioned in'the apertures 33 in the gasket 22. The washer 23 is then pressed onto thesoap and its pins 34 forced therein to lock the washer 23 to the cake of soap against turning movement onthe shank; 21. The cap 25 is thensecured to the shank 21 by screwing its nut-block 24 onto the screw-threaded end 28 of said shank-until its lower edge firmly engages the gasket 22 and presses the same onto the soap to seal the joint between said cap and soap and thereby prevent water from softening the soap so that the shank 21' will pull therefrom. During the final turning movement of the cap 25 onto the shank 21, the pawl 36 engages the ratchet teeth 35 and rides thereover with a yielding action butinterlocks therewith to prevent backward turning movement of said cap on the shank 21. By 'reversely forming the screw-threads 2S and 29, the shank 21 .is locked in the soap ca against turning movement at the time'the cap 25 is screwed thereon. After the cap 25 is finally secured to the shank 21, the retainer cannotbe removed from the soap cake until the same iscompletely gone, at which time the washer 23 is free to move axially on the shank 21 away from the cap 25 and thereby release the engaged ratchet teeth 35 with the pawl 36..
