RECEPTACLE ESPECIALLY ADAPTED FOR MUSTARD.

Specification of Letters Patent.

Patented May 25, 1909.

Application led February 27, 1907. Serial No. 359,704.

T o all 'whom it may concern.'

Be it known lthat we, `CARL FlnEDRlcn WILHELM LINDEWIRTH and EUGEN ARTHUR WIECK, residing at Bielefeld, NVcstphalia, Kingdom of Prussia, German Empire, subjects of the German Emperor, haveI invented new and useful Improvements Relating to Receptacles Es ecially Adapted for Mustard, of which the fo lowing is a specification.

It is a Well known fact that mustard is exposed to decomposition by theV action of light and air, and particularly of the air, whereby the use of the mustard may be rendered extremely prejudicial to health, while its liavor is likewise detrimentally affected. Means heretofore provided for improvingv these conditions are ineffective and are likewise mostly objectionable from the hygienic point of view. In all known devices, the exclusion of air is incom lete, and the mani yulation is not cleanly. wing to the insuflic1ent exclusion of the air, the receptacles in whichthc material isl stored, or from which it is taken .for use form favorable places for the deposit of bacteria, and this is articularly so in places of ublic resort. his of course hastens the ecomposition of the mustard, and the use of such mustard may be highly prejudicial to health. The uncleanly manipulation consists in the use of spoons for emptying the receptacles, these spoons mostly consisting of a material which is attackable by the acids contained in the mustard, thus rendering the latter harmful to health, especially as they are frequently allowed'to remain in the receptacle.A In course of time the appliance used for taking the mustard will be almost entirely decomposed. In addition to this, in all businesses in which mustard is used or sold the hard upper layer of the mustard which, owing to exposure to the air in the receptacle becomes decomposed and assumes a dark brown color, is commonly stirred up with the rest of the mustard contained in the receptacle, as in large businesses its removal would entail a large monetary loss. Accordingly for reasons of economy the laws of health are disregarded. /v

' 'lhe present invention obviates these defects completely. The mustard is protected in the receptacle from the action of air and light. j It is withdrawn in a cleanly manner for use and in accordance with the invention it is unnecessary toopen the receptacle or `the spindle a to rotatewith it.-

employ special spoons or the like. The'mustard always remains fresh to the last drop,

and will keep for almost an unlimited ti1ne This is of especial importance for export and use on ships or during long journeys.

In accordance with the invention, by actuating a train of gearing simultaneously with the descent oll the pressure piston or plunger, that'is to say the emptying of the receptacle by displacing the operating handle, the discharge valve is automatically opened, and on releasing the handle and stoppmg the descent Figure 1 shows itin vertical section, Fig. 2 is a section on the line A of Fig. 6 showing the connecting rod for the lever which is connected with the spindle to which the handle is fitted. Fig. 3 is a front elevation of the fork connecting the handle-s indle with the said connecting rod. Fig. 4 sliows the upper part of the receptacle viewed in the direction indicated by the arrow l in Fig. 1, on a larger scale and partly in section. sents a horizontal section through the operating gear on an enlarged scale. Fig. '6 is a top view of the receptacle, and Figs. 7 and 8 illustrate the hub of the handle in side elevation and in plan on a larger scale.

In the constructional form of the devicel here illustrated the bottom end/a3 of the re- Fig. 5 repreceptacle a is provided at its middle portion with a cavity 'a4 in which the hollow spindle a is guided.A The lid nl is attached to the rece tacle n by means of a bayonet joint, pins o fixed on the receptacle lL-entering angular slots o1 in the lid n1. discharge tube d and the ho low spindle a are mounted in the neck ns of the lid. v The prolonged hub portion b1 of the worm wheel b is formed internally as a hexagon at its lower part; the hexagonal head a1 of the spindle a -is inserted in this hexagonal recess'so that when the worm Wheel b is rotated it causes The'surface The o erating gear, the

of the spindle a is ehamfered slightly inward mounted'in the worm 1], e

spindle for the in order to provide a tight joint for the stationary discharge tube d which is likewise correspondingly chamfered. The casing 1n is fitted to the neck a5 of the lid; it is closed by a lid p and serves for the reception of the worm gear and for the mounting of the wormf. In the neck p1 of the lid p a screw thread is formed into which the correspondingly threaded discharge tube d is screwed. A counter nut g enables the discharge tube d to be tightened or loosened for the purpose of estab ishing a good joint between it and the spindle a.

The spindle e for the handle is displaceabljT the square 'portion e1 (Fig. 5) of the spind insurlng the driving of the worm f when the handle h is rotated. In the cavity m3 of the hub of the worm f, which is closed on one hand by the collar r and on the otherbyan annular part r, a spring m is located for returning the handle to its position of repose; it bears against the collar rFig. 5. The handle h is fixed to the rolonged hub of the worm f. On the hub L of the handle ZL inclined surfaces i, 'il are provided which when the handle h is turned press forward the pin g sliding upon them and which is fixed'on the spindle e, thereby displacing the latter. The hub h1 of the handle is covered by a. cap efixed on the handle h at h2; one end of the -spiral s ring s1 is fixed to this cap while its other en surrounds 'the pin g. The special object of this spring is to assist the rotation of the-handle whenthe latter is returning to its position of re ose.

Above the lid p a rod 7c is mounte in the same direction as the spindle e and is likewise subjected to the action of a spring m1. The rodI 7c rests in bearin s z z2 which are cast upon the lid p. A for tis fixed to the rod k,

.l rod k is likewise displaced in the same direction owing to the connection of the two parts l by' means of the fork t. On the end of the rod Zc opposite'to the fork t an arm v carrying a pin' v is xed. This pin engages in 'the longitudinal. slot 'w' in the arm 'w which is mounted on the rod c-'whichrests in bearin s x, z fixed to the lid p at an angle Ato the rod This rod also `carries an arm Z provided. with la universal joint y. In this joint there eniges va lever'lzwhich is jointed to the arm Z3 ed tothe valve body d3.

A sprlng n is soldered-to the lid ni at z and -presses on-'the-piston c in the raised position of the latter in order to insure the engagement of the screw threads on the piston and urpose o f depressing the p1ston.-.To faci tate the manipulation of the piston c it is provided with a collar c3 which is preferably screw-threaded to' enable the iston to be inserted and withdrawn readl y. The tapering annularspace c* inside lthe screw threaded hub of the piston c has for its object to permit of the discharge of the contents of the receptacle through the openings a3 provided in the lower part of the spindle (L even in the lowest position of the piston. Between the piston ring c2 and the leather sleeve c an annular space c5 tapering upward is left free; the material is forced into this space upon the depression of the piston. By this means a good joint is formed between the sleeve c and the inner wall of the receptacle n and considerable friction is produced between these parts for the vpurpose Voi' preventing rotation-ol' thev piston c with the spindle a. The leather sleeve c is fixed on the piston ring cgby an annular part c by means of screws c7. All the parts of the receptacle and of the discharging device which come into contact with the. contents are formed of acid prooi' material, such as ebonite, porcelain or the like.

The valve casing d2 intersects the valve body d3 at the outlet in order to prevent dripping after the valve d vhas been closed. Any drops remaining pendent are carried inward when the valve body d rotates, or are cut oil' by it so that they fall into the vessel placed below for the reception of theinustard.

The operation of the apparatus is as 'follows :s-After lthe receptacle 'n has been charged, the spindle e 1s iirst of all inserted so that it rests in the cavity n* in the bottomn3 of the receptacle. The piston c is then loosely mounted on the spindle a. and the'lid 'n' is closed. By the action of the spring-1n2 on the piston c, when the handle h is rotated the screw thread on the piston is caused to mesh with the thread of the hollow spindle a. At the same time, owing to the-pin g striking against the inclined surfaces t, '1, on the hub h of' the handle, the spindle ef is displaced. By means of the fork t they rod Ic is displaced in the same direction whereby the springs m, fnt, s are compressed.v The rod Zc, by means 'w aside, whereby the ro cis rotated Jand the. arm Z of this rod lifted. By this means th lever Z2 is pressed upward and the valve body d3 is rotated-by the arm Z3 which is jointed to the lever Z2, that is to'say, the discharge valve d is opened. By the further rotation of the handle the piston -c'is depressed whereby the material'with which the receptacle is'charged is caused to escape through the o enings a inthe hollow spindle a out of the atter i'nto the discharge tube d and thence through the .of the arm 'v' and pin "v" resses the lever arm used equally well for, appliances from which the material is taken for use or receptacles in which it is stored, may of course be modified in various Ways.

By means oi' the arrangement described, it is possible as soon as a receptacle is emp'- tied to remove the lid readily and fit it to a freshly filled receptacle and thus toa certain extentan operative system is provided.
