Application filed July 1, 1910. Serial No. 569,955.

To all 'whom it may concern;

Be it known that I, CHARLES F. STRAS- BURGER, a citizen of the United States, re-

.siding at 616 West Kinzie Street.l Chicago,

v a self-contained apparatus, which shall involve a simple construction and operate on 'the plunger principle to reliably measure tained elements,

- by inspection cessive the. product will be render and indicate, y comparison, the consistency of liquids, including semi-liquids such as catsup and others of analogous density. v In he manufacture, for example, of catsup, for testing which I have more especially devised my improvement, the matter of obtaining requisite density or consistency of the product is the result of boiling for the proper time, which is liable tol be too short or too long, and is not reliably determinable while the material is in hot condition. If the boiling be too little, the product, u on cooling, 'will be unduly thin and accordi and consumer, while if the boili be exunduly thick by cooling and fail to discharge prop` erly from the bottles in which it is used, which not only vinjuriouslyljtfects the salability of the article but decreases the profit of manufacture by depriving it to an unnecessary extent of the cheapest of its connamely, water. By means of my improved apparatus, the consistency may be ascertained ata glance to determine whether more cooking 1s required or the product has been cooked to excess. In the accompanying drawing, Figure 1 is a view of my improved device in sectional elevation, the section being taken at the line l on Fig. 2, and Figs. 2, 3 and 4 are enlarged sections lines 2, 3 andvft of Fig. 1.

A reservoir 5 for thermatter to be tested is shown as a part of the apparatus,l though the actual testing means may be applied to ngly objectionable `to the trade. end normally in -the pat freleasably holding the plunger and rod in taken, respectively, on

any such holder, including the kettle in which such matter is prepared. The holder shown is adapted to receive a mere sample of said matter and is shown as a cylinder provided with a handle 6 by which to carry it and closed at its ends. The removable top of the holder has sockets 7 rising from it, of which four are shown. Posts 8 are seated and fastened in these sockets and extend into and are fastened in sockets 9 alining with the sockets 7 and depending yfrom a head 10 having a central sleeve 11 extending upwardly from it for guiding the rod 12. provided with a stop 13, of a. plunger 14 in the holder and of 'the open construction represented' 'or of any analogous suitable construct-ion. The rod 12. which Works through the head 10, carries, for the tripping purpose hereinafter described, an abutment Whlch is practically a. partof the rod but is shown as a sleeve 15 fastened, as by set-screws 16. to render its position on the rod adjustable. A sprintf-,pressed lelver 17 fulcrumed between its en s on a stud 18 depending from the head 10, is maintained by its controlling sprin 19 with its inner of the Stop 13 for its uppermost elevated position read;r to descend on disengaging t-he'lever from the stop for the purpose hereinafter explained.

A wall 20 rises from the head 10 and has projecting .from it., atv right-angles to each other, arms 21 and 2Q between the outer ends of which extends and has fastened at its end-portions to them, as by pins 23. a segmental gage-plate 24`bearing-upon its display-surface an arbitrary indication of measurement. A wall 25. shown of general Z-shape. rises from the head 10 in spaced and parallel relation to the wall Q0: and ona pin 26 supported in these two walls to eX- tend across the space between them 1s Journaled the hub 27 of an index-finger 28, the

,forward end ofwhich is adapted to engage A`the lower pin 23 as a stop to arrest it agalnst movement beyond its normal horizontal position, and the` opposite end of which forms a projection` 29 extending into the path of the sleeve 15. A brake-shoe 30 is provided on a stem 31 reciprocatingly supported on the upper horizontal end of the Z-shaped wall 25 to cause the shoe to bear, under the pressure of a spring 32, against the hub 27.

To apply the apparatus to its purpose, the reservoir is filled with a predetermined quantity of the matter to be tested, say catsup in the hot condition in which it is taken from the kettle wherein it has been boiled. Thereupon the lever -17 is turned to release the rod 12, permitting the plunger 14 vto descend in the reservoir with'a degree of force according to the density of the contents, and in the descent the sleeve 15 encounters the finger-projection 29 with impact-force sufficient to suddenly turn the index-finger upon its axis. The extreme point on the gage with which the force of the impact causes the nger to register, and at whichA the pressure of the brake will arrest it, denotes the density of the contents of the reservoir as compared with a predetermined point on the gage ascertained by using it on similar contents of known consistency.

After making a test in the manner described, the ap aratus may be restored to its normal condition to prepare it for another test by raising the plunger into the position wherein the lever 17 will engage its rod to lhold it, and turning the index-finger back to the stop 23.

What I claim as my invention is:
