LIQUID-SOAP. DISPENSER.

to effect the delivery of the liquid material from the bottom portion of said container.

In this class of devices it is usual to employ a container composed of glass and a metal fitting for a dispensing valve, the container being. manufactured by the process commonly known as blowing the glass.

As is well known, blow glass containers vary in dimensions, and this-is trueparticularly in the case of containers an end portion of which is contracted to produce a neck for the attachment of a metal fitting, the problem being to so coordinate. the metalfitting and theconta-iner as to secure a llqu d-t-ight joint at the bottom of said container and to also insure the proper relationship ofv the n metal fitting to the glass container. Moreover, in the practical operations connected with the production of the container, it is necessary to grind off the end. face of the glass at the neck, but experience shows that even with this precaution a considerable variation exists in the end faces of. the necks f of different contalners similar in design and a size, and, further, that it seldom happens that the lower end of thecontainer. is ground off at a right angle, to the axis of said container as should be done. 7

One partof this invention consists of means whereby the glass container and the metal fitting are mutually adapted to each other in such a manner as to secure aliquidtight connection between the bottom part-of the container and the fitting as well as to compensate for variations in the form and dimensions of the container. To these ends, the container is provided with a neck the lower part of which is formed wit-han external thread, whereas the fitting isprovided with an internal thread so as to enable said parts to be separably coupledby a screw connection. A compressible gasket is positioned at a suitable point intermediate the container and the fitting for the purpose of securing the desired liquid-tight connection, and in a preferred embodiment of the invention the neck portion of the container is novided with a shoulder intermediate the Application as, June 9,1919." Serial No. 302,972.

tacts the gasket, thus enabling me to securea true and even bearing surface for said gasket in order 'to compress the latter by screwing the fitting into position, the finish or the physical condition of the glass at the bottom of the neck being immaterial so far as concerns the liquid-tight connection for the reason that said fitting does not contact with the bottom face of the neck, hence it is not required that said bottom face of the neck be ground off at right angles to the axis of the glass container.

Another part of the invention consists in means for precluding the removal of the metal fitting from the container when the latter is mounted in the supporting member, and, further, to provide means whereby the container may be attached toand dismounted from the supporting member wlthout subjecti'ng said container to breakage or fracture during the performance of the mountin;; or dismounting operations.

To these ends, I construct the neck portlon ofthe container ma manner to produce a plurality of collars one of which is of less diameter than the other so as to permit the ready movement of the valve fittings-and container neck through thefsupporting member. The collar of largerdiameter is formed with a male thread adapted to be screwed, into a ;fcmale, thread provided within an annular part of the supporting member,

.whereby the collar at the neck portion of the container may be attached to the supporting member without permittingthe glassv body to come into contact with the supporting member so that the container can be attached and detached with a minimum risk of fracture.

The metal fitting for the dispensing valve is formed with a tubular member and with an outstanding flange, and in assembling the fittingrelatively to the container this tubular member embraces the collar of small diameter on the neck whereas theflange of said fitting is spaced by the interposed gasket with respect to the shoulder intermediate the two'said collars of the neck portion. In mounting the container on the supporting member, the threaded collar is screwed into the annular part until the flange of the fitting is in contact with the flange ofsaid annular part, as a result of which the eontainer has a firm bearing in the annular part ends of said neck, with Wl1lCl1 shoulder conand the-flange of said metal fitting is so seated upon the flange of the annular part that said fitting or the valve cannot be detached from the container during the period that the container is attached to the supporting member.

In this connection it is desired to state that the lower threaded part of the glass neck is free from contact with the annular supporting member and, further, that the flange of the metal fitting is so seated upon said annular supporting member as to utilize the elasticity of the gasket as a bufier in reducing the stresses upon the glassware when mounted on the bracket.

Another part of my invention consists in the provision of means for locking the container to the supporting member, and the same being effective in all variations in the dimensions of that part of the container with which cooperates said locking means. To these ends, the collar of large diameter is provided with a bevel on its upper face, which bevel is exterior to the collar and positioned well below the surface of the container body. Cooperating with said beveled face is a locking member, preferably embodied in the form of a screw mounted in a part of the supporting member, and in one form this screw is concealed from access when in operative contact with beveled face of the container.

Other features and advantages of they invention will appear from the following de scription taken in connection with the drawings, wherein- Fig. 1 is an elevation, with certain parts in vertical section, of a soap dispenser embodying this invention.

Fig. 2 is an elevation of the lower part of the container detached from the bracket and illustrating the format-ion of the neck thereof.

Fig. 3 is a. detail view, partly in section and partly in elevation, of the supporting bracket.

Fig. 4 is a detail view, partly in section and in elevation, of the metalfitting for the dispensing valve.

Fig. 5 is a plan view of the fitting shown in Fig. 4:.

The container A is composed, preferably, of glasshaving a desired shape and dimensions. Said container is preferably closed and flattened at the top, as at a, in order that on dismounting it from the bracket F said container may be turned over and rest upon a table, or other surface, for filling and cleaning it, the flat surface a affording a firm bearing for the container when inverted. Another advantage is that the container is hermetically closed at the top and that it requires no cover for a top opening, thus attaining economy in the manufacture of the container and dispensing with a separate cover, the latter in other styles of con- .metal stamping may be used.

tainers being composed of metal adapted to be locked in place and affording an additional item to the cost of manufacture. The bottom part of the container is formed with a neck, indicated generally at B and in efiect consisting of two collars 6 Z), whereof the upper collar 6 is larger in diameter than the lower collar Z). The upper collar extends for an appreciable distance below the body of container A, and the outer surface of this collar at the upper portion thereof is formed to produce an incline or bevelc sloping downwardly and outwardly from that surface of least diameter at the under portion of the container, see Figs. 1 and 2. Said collar 6 is formed on its annular surface and below the bevel 0 with an external thread .72 see Figs. 1 and 2. Incidental to the use of two collars b b of different diameters, a shoulder or ledge b is produced on the neck, see Fig. 2. The smaller collar Z2 is provided with an external thread cl, the same extending preferably from the shoulder b to the lower edge of the neck B, the under face of which neck may be finished in any desired way.

The neck at the lower part of the container opens downwardly, see Fig. 1, said opening being closed by a metal fitting C containing a dispensing valve E, said fitting being of the kind shown generally in my prior Patent No. 1,235,913, and the said valve being constructed and adapted for operation as disclosed in said prior Patent No. 1,235,913, and in Patent 1,199,913, and reissued Patent 13,898. The fitting is composed preferably of a die casting although a As shown, said fitting comprises a tubular body f, a depending boss f and a radial flange 6 at the top edge of the tubular body. The tubular body is open at the top flanged portion 6 thereof, whereas the boss f isopen for the operation of the valve stem. Said tubular body f is provided with an internal thread g, corresponding to the external thread d of the container neck, whereby the fitting is adapted by a rotative movement to be screwed detachably to the lower collar 7) of the container neck B.

The containeris composed of glass and is produced in the manner usual in the art' by blowing the glass, the container used in my invention being provided with a depending neck characterized by a form of construction which includes the two threaded collars Z) Z) and a shoulder 6 the plane of which shoulder is intermediate the threads Z), d. It is usual in the production of glass containers with neck portions to true up the end face of the neck by grinding off the glass, said grinding operation being performed with more or less irregularity as a result of which the bottom or end face of the neck may or may not be in a plane at a right angle to the vertical axis ofthe con' tainer.

D is a gasket composed of compressible material, the same consisting preferably of rubber and the internal diameter of which corresponds substantially to the diameter 9f the lower threadedcollar b of the neck.

Said gasket is fitted around the collar 11 and into contact with the shoulder 6 the latter acting as a seat for said gasket. The fitting C is screwed upon the collar b for the upper flanged edge of said fitting to have contact the neck B that when said fitting is screwed upon the neck so as to compress the gasket said fitting does not come into contact with the end face of the neck B, see Fig.1, whereby any irregularity in the plane of the end face of the glassware will have no effect upon the liquid tight connection between the glassware and the metal fitting, it being noted that the shoulder b is in' a plane substantially at right angles to the axis of the container so as to constitute a trueand even bearing surface or seat for the gasket.

l/Vhen the container is screwed into the bracket, the flange eof the metal fitting is in contact with a flange m of the metal bracket; in other words, there is no direct contact between the shoulder 5 of the glassware and the flange m of the bracket, but on the contrary, there is a metal to metal contact due to the engagement of flange 6 with flange m, the elastic gasket D being intermediate the shoulder b and'the flange m of the metal bracket. In the operation of coupling the glass container to the metal bracket, the container is screwed into the bracket until the flange c of the metal fitting arrests the rotative movement, the gasket D serving as a butter or cushion between the glassware and the metal bracket.

The container is mounted detachably in a supporting member F, shown in Figs. 1 and 3 as a bracket, the arm 7 of which is integral with a face plate 71 and a ring 7', said face plate being attached in a suitable man ner to a wall or other surface. The ring is formed with an internal thread is, corresponding to the external thread 5 of the neck, and said ring is provided with a flange m, the same being positioned at the bottom edge of the ring and extending inwardly with respect thereto and beyond the plane of the internal thread in. The bracket is provided with an upstanding lug a, for suporting a container locking member herein 'ahown as a screw G, although it is apparent other means may be employed for retaining the container in a locked relation to the bracket. The screw is mounted in a thread provided within the lug n, and in the form shown the screw is adapted to be so positioned that its end portion is concealed by and within the lug,thus precluding unwarranted access to the screw and requiring the use of a suitable key G, see Fig. 1, for the manipulation of the screw in order to unlock and lock the container with reference to the bracket. 7

Assuming that the container is dismounted from the bracket and that it is desired to charge it with the liquid material, the container is turned over and placed on a table,

etcJ, resting upon the closed flat face a. The

metal fitting is now disconnected by a rotative movement in order to unscrew it from the neck B, thus permitting the fitting and the valve to be taken off the container, The liquid material is nowintroduced through the opening in the neck, after which the gasket D is placed around the collar 1) so as to "rest against shoulder 5 and the fitting and the valve are replaced in order that the fitting may compress the gasket D. The

'fittingis screwed on the collar in a manner to tightly close the open neck of the con-' :tiner so as to render the latter substantially air and liquid tight. The container is now turned back to a normal position and the neck, fitting and valve inserted into the ring j of the bracket, the container being rotated bodily forits external threads 6 to engage the internal threads k of the bracket. The

rotation'of the container is continued until the flange e of the fitting contacts with flange m of the bracket, the further rotation and downward movement of the container being "arrested by flange e occupying the bracket flange m, and the valve and the fitting protruding well below the bracket. The look i screw G is now rotated in the lug n for one end of the screw to have contact with the beveled face 0 of the container, whereas the other end of the screw is concealed against access within the lug n, the rotation of the screw being performed by aid of key G, or

other appropriate tool.

It willbe noted that the container has a fiXed engagement with the bracket by reason of its threads 5 being in direct contact with the threads and its shoulder 6 being in indirect contact with flange m of the bracket,

and,further, that it is locked to said bracket,

by member G, or its equivalent, thus precluding surreptitious removalv of the container. Again, the flange e cooperates with the flange m of the bracket in preventing removal of the fitting and the valve from the container when mounted in the bracket; but to remove the container, it is necessary to withdraw screw Gfrom the path of bevel afand to unscrew the container from the bracket, the fitting C and valve E being cleaning it withdrawable with said container in order to preclude any escape of liquid material therefrom.

The parts of my new dispensing device may be manufactured economically, one reason therefor being that the glass container having one opening only can be produced at a cost of one-half to two-thirds below the cost of a glass vessel with openings at the respective ends, it being necessary to grind off one end portion only of the container, and no cover bein required for the top of the cont iner, so that the cost of one grinding operation and of said cover are saved and, moreover, the container is airtight at the upper end portion thereof. Again, the bracket and the valve are inexpensive in construction, while at the same time these metal parts are substantial, durable and efficient.

Devices of this character are exposed to the accession of dirt and become quickly soiled in use, but in my device the container is readily dismounted from the bracket, thus permitting free access to the bracket for and enabling the operator to dismount the valve and the fitting from the container, whereupon the container can easily be cleaned and refilled and the valve can also be easily cleaned to remove any adhering foreign matter tending to clog up the valve, it being apparent that the valve is exposed for repairs, if necessary. Moreover, no very accurate or nicety of adjustment is required between the fitting and the container, or the container and the bracket, but when the container is screwed into, or unscrewed from, the bracket the glass body of the container does not come into contact with the bracket or any part thereof, thus minimizing the liability to breakage on the part of the container when mounting or dismounting it.
