GEORGE F. SHAVER, 0F NEW YORK, N. Y., ASSIGNOR TO HYGIENIG SOAP GRANULATOR COMPANY, A CORPORATION OF NEW JERSEY.

SOAP-SI-IAVING DEVICE.

Specification of Letters Patent.

Patented Feb. 7, fllt..

To @ZZ whom it' may concern:

Be it known that I, GEORGE citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful ln'iprovements in Soap- Shaving Devices, of which the following is a specification.

'lhis invention relates to a device which is primarily designed as a toilet fixture adapted for use in connect-ion with wash basins for the purpose of supplying soap in such a form that it may be readily and economically used and is intended to do away with the use of a cake of soap in the ordinary manner in the hand.

it has been found by many experiments with soap in various forms that when the soap is cut or shaved into thin narrow strips or shavings the same dissolve or saponify very readily and consequentlyT a inuch smaller quantity is necessary in this than in any other form, as the entire amount shaved ofi' is dissolved and used, resulting. in a greater economy in the use of the soap.

To produce soap shavings in the form above described l provide a machine having a rotatable cutter and a scraper which is adapted to operate in conjunction with this cutter, s will be more fully described hereina-fter.

l t has been found that much better results are produced when the cake of soap is held against the cutter with a uniform pressure as the soap shavings will be of uniform thickness and the cutter is much less liable to clog and will operate much more smoothly and efficiently under these conditions.

In order to hold a cake of soap against the cutter with a uniform pressure I provide a device which is in the nature of a laz F. SHAVER,

tongs actuated by a spring. One end of the series of toggle levers is fixed in position and the opposite or moving end attached to a disk adapted to press against one end of the cake of soap and hold the saine against the cutter. rihe operation of this feature of the device will be more fully explained in the drawings accompanying this specification.

ln the drawings like parts have been given similar reference numbers in each of the figures.

Figure l is a side elevation of a device embodying my invention having port-ions thereof broken away showing the interior construction. Fig. 2 is a vertical, central cross-section, showing the relative position of the several parts of the device. Fig. 3 is a cross-section on the line Sq?) of Fig. 2. Fig. 4 is a cross section on the line 4-4 of Fig. 2. Fig. 5 is a cross-section on the line 5-5 of Fig. 2 Fig. 6 is a cross sectional view of the cutter taken on the line 6 6 of Fig 4. Fig. 7 is an end view of the scraper, shown in plan view in Fig. 5.

n the soap shaving device which l have chosen to illustrate my invention in the drawings herewith a vertical soap container l, is preferably cylindrical in form constructed of sheet inetal and provided with a suitable cover 2. A support or bracket 3 of suit-able form may be provided for attaching the same to the wash basin or toilet fixture with which it is to be used. One end of such a bracket is shown at 3 where it projects through the container l and is riveted thereto thus forming a support for a vertical shaft which is adapted to rotate the cutter 5. A. suitable handle and lever such as 6 is provided at the upper end of said shaft which projects through a suitable bearing in t-he cover 2. This bearing is of peculiar construction and is so designed as to prevent any water leaking through the cover to the interior of the container. As the hands of the operator are often wet this might readily occur.

The upper end of the shaft is iiattened on two sides and adapted to receive the handle 6. An inverted cup shaped member is held in position against the shoulder formed by the aforesaid flattened portion of the shaft 4, by the handle 6, which may be held in place by riveting over the upper end of the shaft. A supporting member 8 is fastened to the inside of the cover 2 and into this member 8 is forced a bushing 9, which is held thus in position so as to preserve the alinement of the shaft 4. This construction provides a substantial bearing which will prevent any water from leaking from the outside of the cover to the interior of the soap container.

A collar lO is secured to the shaft 4 and provides a shoulder which prevents the shaft 4 from being' forced upwardly by the action vof the lazy tong levers. An outer sleeve 11 surrounds the aforesaid collar and the lower end of the supporting member S and forms a support against which the col.- lar 10 may rest and so retains the shaft l in position. Two sets of lazy tong links 12 and 13 are pivotally attached to the aforesaid sleeve 11 on opposite sides thereof and a second pair of crossed levers 14: and 15, pivoted at their intersection, are attached thereto forming a device known as the lazy tong. At the outer ends of these levers a coil spring is attached which is normally under tension and operates to pull the outer pivotal points together and so force the lowerend of the levers downward, as will be seen by referring to Fig. 2. n

At the lower end the levers 14 and 15 a set of links 16 and 17 are attached and also a spring connecting the outer ends thereof which operates in the same manner and in conjunction with the one already described. The lower ends of the links 16 and 17 are pivotally attached to a sleeve 18, which is in turn attached to a disk 19 which engages the upper surface of the cake of soap 20. It is thus seen that the operation of this lazy tong device is to force the disk 19 downward against the cake of soap thus holding the saine against the rotating cutter 5. It will also be seen that when the disk 19 is in its uppermost position the springs 21 and 22 will be extended and will exert the maximum. pull on the levers, but in this position the pivotal points of the levers are more nearly in a straight line and consequently the resultant pressure downward at right angles to the line of pull of the spring is at its minimum. As the disk moves downward the relative resultant action increases o-n account of tie increased leverage due to the relative posit-ionv of the several pivotal points, but the actuating force of the spring at the same time decreases and consequently a unifo-rm downward pressure is produced from the highest to the lowest position of the disk.

lWhen the disk is in its uppermost posi tion the pivot-al centers of the levers are so nearly in a line with the pull of the springs 21`and 22 that it has been found desirable to use an auxiliary spring 23 which is carried loosely upon the shaft 1 and rests against a collar 24C which is secured tothe disk 19. This auxiliary spring 23 is of such a length that itis not brought into action except over approximately the last third of the travel of the disk to and from its uppermost position. It is thus seen that maximum downward thrust of this auxiliary spring 23 willv be at thepoint where the pivotal points of the levers, which are actuated vby the springs 21 and 22, are in nearly a straight line and the object of this auxiliary Vspring is to insure the positive operation of the whole mechanism and prevent the levers from becoming locked in position on account of the friction between the parts or other causes.

The cutter 5 is provided with a centrally located hub or shaft 2 5, which is secured thereto. The upper portion of this hub provided with two projections or ears 26. A sleeve or extension 27 is attached to the lower end of the shaft 4l and is provided with slots adapted to engage the aforesaid projections 26 on the hub 25 and so form a separable connection between the shaft and cutter for rotating the latter when the handle is turned. YThis construction permits the removal of the cover of the con tainer together with the shaft and attached parts, leaving` the cutter in place in the container.

The lower port-ion of the hub 25 extends through the support and at the lowerI end thereof is attached a cleaning plate 28. This plate is preferably formed from ay thin sheer of metal having` a portion thereof bent into circular' form providing` an opening adapted to receive the lower end of the hub shaft 25. This opening is of such a size that the plate fits tightly over the shaft and is rotated thereby but in case it meets with any ohstruction other than the soap shavings the shaft will slip in the opening and will not be prevented from rotating. The object of this cleaning plate is to prevent the accumulation of the soap shavings which are very thin and light and are very apt to lodge and collect in the lower portion of the container instead of falling freely into thc hands of the operator as intended.

The cutter 5 is of such a construction as to shave or cut the cake of soap into thin narrow shavings and to accomplish this result a series o'f serrated cutting edges, preferably in the form of saw teeth projectimls, are provided. A simple and cheap design of such a cutter is shown in Fig. 4. This cutter is formed from a disk of metal slightly smaller in diameter than the interior of the container. This disk has portions thereof cut away and on the advancing edge of these openings saw teeth projections are provided having the points thereof bent slightly upward above the surface of the disk and having a sharp cutting edge inclined at about 35 degrees with the plane of the disk. A cross section of one of these cutting teeth is shown in F ig. (l. Openings in the disk are of large size in order that the soap shavings will readily fall through and not collect and clog the cutter.

The several series of cutting edges are preferably arranged so as to extend radially from thecenter of the disk and in order to provide greater strength and rigidity alternate series extend only a part of the distance from the center to the circumference,

llO

one series extending from the center a part of the way outward and the adjacent series extending from the circumference a part of the way inward. This arrangement provides a cutter which will cut the entire surface of the soap and at the same time allows the disk to be so formed that a much stronger construction is provided than would be the case if each series of cutting edges extended to the center from the circumference.

Mounted upon the support 3 is provided a scraper 29, which is preferably constructed of thin sheet metal and adapted to be slipped over the support 3, as shown, so that the upper surface thereof will be adjacent to the under surface of the cutter. rlhis scraper is provided with a projection 30 at one side thereof having a sharp edge and is intended to cut away or scrape off the soap shavings which hang below the cutter. This has been found to be very effective in preventing` the accumulation of lsoap shavings which would clog the cutting edge and so prevents the most effective operation thereof. The relative position of this scraper and cutter is shown in Figs. 2 and 4 and the scraper is shown in detail in Figs. 5 and 7.

The cake of soap is of a construction especially adapted for use with this machine and is preferably cylindrical in form and of slightly smaller diameter than the interior of the container. A central opening in 'the cake is provided which is of such a size as to permit the shaft 4to be operated theretln'ough. At one side of the container a projection or fin 3l is provided and a corresponding slot or keyway is provided a t one side of the cake of soap. This slot engages the fin 3l and the soap is prevented from rotating with the cutter. A similar' slot is provided in the disk 1S), which preferably corresponds in its outline to the end of the cake of soap, as shown in Fig. 3, which also engages the fin 3l and so prevents the dish' and attached lazy tong device from rotating with the shaft.

'lhe construction of the cake of soap and the relative location of the retaining fin is shown clearly in F ig. 3. The cover of the container l is adapted to fit over the outsiccof the upper end thereof. Projecting pins such as 32'from opposite sides of the container l enter openings 33 in the cover. llhis forms an ordinary bayonet joint and as the cover' is pressed into place a turn brings the pin into the horizontal portion of the openings 33 thus locking the cover in place.

Referring to Fig. l, a lever 34 is pivoted to the cover at one side thereof and is held against' a stop in such a position that one end thereof closes the horizontal portion of the opening 33 above referred to. As the cover is forced down upon the top of the container the end of the lever 34 is raised by the pin 32, allowing the same to pass into the horizontal portion of the slot as shown. Thespring above referred to forces the lever into the position shown and the cover is locked in position until a key is inserted in the opening 35 provided therefor and turned so as to raise the lever 34 and release the pin in the bayonet joint. This provides a simple and effective lock for preventing the container from being opened.

lt will be evident that the several features of my invention may be used individually and apart from one another if desired as well as combined in one device, as shown in the drawings.

As many changes may be made in the details of construction and many apparently different embodiments of my invention could be made without departing from the scope thereof, l intend that all matter contained in -the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
