FILLING-MACHINE.

SPECIFIGATON forming part of Letters Patent N o. 683,016, dated September 24, 1901.

Application tiled April Z9, 1901. Serial No. 57,986. (No model.)

To all whom, t may con/cern:

Be it known that we, J AMES BAXTER and DAVID BAXTER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling-Machines, of which the following is a specication.

This invention relates to machines for filling cans, bottles, and the like collectively and with uniform quantities of liquid of the type illustrated in Unit-ed States Letters Patent No. 640,987, granted to us on the 9th day of January, 1000; and the invention consists in certain improvements, more particularly in the nature of an attachment tothe type of machine illustrated in the said Letters Patent, whereby the serviceableness and utility of the machine is extended, the object of the present invention being to enable the said machine to be used for filling cans, bottles, and vessels having contracted openings,\vhich are usually closed by a screw-threaded cap or ordinary plug-stopper.l

While the invention has been designed more especially as an attachment for the fillingmachine forming the subject-matter of our prior patent above referred to, yet it will 'be obvious from the following description that the same is applicable generally to machines of this type in which itv may be desired to provide means directing the flow of a liquid or other highly-mobile substance from a series of measuring-chambers into a corresponding series of receptacles having contracted receiving-openings.

A iilling-machine in which are incorporated the improvements forming the subject-matter of our present invention is illustrated in the accompanying drawings, in Which- Figure lis a side elevation showing the filling attachment in its elevated position. Fig. 2 is an end elevation of the same, the depressed position of the filling attachment being indicated in dotted lines. Fig. 3 is a plan view taken on the line 3 3 of Fig. l, and Fig. 4 is an enlarged detail illustrating the conjunction of the filling attachment with the necks of the cans or bottles during the filling operation.

In the drawings, A represent-s a suitable supporting-frame, which carries at its top the receiving and measuring tank of the apparatus, designated by B. This tank B is a plain rectangular metal casting, which is divided into a series of equal-sized measuring-cells by means of suitable longitudinal and transverse partitions, as fully shown and described in our former patent hereinbefore referred to. Inasmuch as the formation of this tank 6o forms no part of our present invention, the same need not be particularly described.' It

is', however, noted that the bottom of each cell has a centrally-located discharge-aperture, the several apertures in each longitudinal row of cells being controlled by a valvestrip O, which valve-strips O are connected at one end thereof bya transverse tie-barC, whereby the several valve strips may be caused Vto operate in unison through the 7o agency of an operating arm or lever D, all as clearly set forth in our aforesaid patent.

vE represents a pair of cross-bars connecting the legs of the frame near the lower ends thereof at opposite ends of the machine. In each pair are journaled a series of rollers e, forming an antifriction-track for the reception and removal of a box or case F, the latter containing a series of uniformlyspaced or positioned cans, bottles, or other receptacles 8o G. These cans or receptacles, in accordance with the purpose ofour present invention, are provided with openings of contracted area, as shown at g, such openings being ordinarily closed by a screw-threaded cap or by au ordinary cork or other stopper.

Referring now to the mechanism in which are embodied the improvements forming the subject-matter of our present invention, H designates a'series of funnels, there being 9o one for each of the measuring-cells contained within the tank B. These funnels are preferably arranged in a series (here shown as three) of rows of funnels disposed side by sido longitudinally of the machine, the funnels in each row being separated from each other simply by vertical partitions therebetween. The series or rows of funnels I-I are supported and carried on va'suitable baseframe I, which frame is suspended from and roo normally drawn toward the base of the tank B by'means of a series of tensile springs J, connecting said parts in the manner plainly shown. Each of the parallel longitudinal bars or plates of the frame I has formed therethrough a series of apertures z', corresponding in number and relative location to the superposed funnels H, each of the said apertures being entered through the greater' portion of its depth by the lower end of a vertical discharge-nozzle h, connected with the bottom plate of the funnel-body. The several longitudinal rows of funnels H are supported vertically upon the frame I by means of two or more hollow or tubular members K, depending from the base-plate thereof and telescoping a corresponding series of posts or pins L, extending verticallyfrom the longitudinal members of the frame I, whereby provision is made for the ready positioning and removal of the funnels upon their supporting-frame.

The series of funnels and the frame carrying the same are designed to be vertically shifted between a position directly beneath the discharge-orifices of the measuring-cells, as shown in full lines in Figs. l and 2, and a position directlyabove and contacting with the cans or other receptacles contained in the case F, as shown in dotted lines in Fig. 2. In order to effect this movement of the funnelc'arrying frame in a manner adapted to secure a close and perfect registration of the the form of pins through the vertical slots of the guides M and also through longitudinal pivoted at 0 to the vertical members of the frame A, at or near the upper -end thereof, at one end of the machine. The opposite ends of said levers O are connected by a transverse horizontal handle-bar O', as best shown in Fig. 2. Pivoted at p to the vertical members of the frame adjacent the free ends of the levers O are a pair of slotted guides P, the slots of which engage pins p' in the outer faces of the levers O, near the free ends of the latter. One of these pins p is screw-threaded and carries an arm p2, by turning which the lever O and slotted guide P may be rigidly clamped together in any desired position. The longitudinal bars of the frame I are chamfered on their under surfaces around the apertures t', as at for a purpose which will appear later in the description of the operation.

Referring to the operation of our improved attachment, it is noted that the normal position of the frame I and the series of funnels H carried thereby is as shown in Fig. 1,

wherein said parts are elevated to occupy a position directly below the `discharge-apertures of the measuring-tank B and to freely permit the placing and removal of the box of cans or other holders to be iilled. This boX having been placed in proper position beneath the measuring and guiding parts of the machine, as shown in Figs. l and 2, the handle-bar O' is depressed by the operator, thereby swinging downwardly on their pivots the levers O, which latter carry with them the connected frame I and the several rows of funnels H carried thereby. By the continued depression of the handle-bar O the funnels H and their supporting-frame I are carried downwardly until they occupy the position indicated by dotted lines in Fig. 2 directly upon and contacting the receivingnozzles g of the cans G. During the latter operation the lower chamfered edges of the apertures 'L' engage the top edges of the nozzle g of the cans and by their cooperation therewith serve to properly center the apertures and nozzles in a manner that will be readily understood, thereby insuring the proper positioning of the discharge necks or throats h of the funnels H relatively to the nozzles of the cans G, the vertical axes of the two said elements becoming coincident, or substantially so, as clearly indicated in Fig. At,wherebya proper discharge of the syrup or other material being handled is insured, with the provision also of an adequate annular space between the inner surface of the nozzle g and the outer surface of the neck 7L to permit the free escape of air or steam from the can as the filling operation proceeds. The verticallyswinging frame I and the funnels carried thereby having been thus depressed into snug registration with the tops of the cans, they are temporarily locked in such position by a partial turn of the arm p2. The lever D being then swung in a direction to open the discharge-valves of the measuring-cells, the syrup or other liquid flows therefrom into the wide open mouths of the funnels therebeneath and by the latter is guided and discharged into the necks or nozzles of the receptacles G. When the filling of the latter has been completed, the clamping-arm p2 is released, and the springs .l immediately return the frame and its contained funnels to their elevated position, as shown in full lines. The box F, containing the filled receptacles, is then free to be withdrawn and replaced by another similar box containing empty receptacles, whereupon the above-described operation is repeated. Any time when it is desired to remove any or all ofthe longitudinal series" of funnels to be cleaned, repaired, or for any other reason this is readily accomplished by merely depressing the frame I in the manner above described and raising the funnels off their supporting-pins L. The slotted vertical guides M, cooperating with the upper and outer eX- tremities of the hangers N, insure the ver- IIO IIS

tical movement of the frame I between its elevated and depressed positions, and by reason of the fact that the frame I is, in effect, pivoted centrally bythe hangers Non its operating arms or levers O it is capable of'a slight vertical oscillating or rocking movement when forced into registering engagement with the tops of the receptacles, thereby adjusting itself automatically by continued downward pressure on the operating-bar O to a snug registration therewith, in which operation the chamfered lower edges of the apertures t' are effective, as above described, to secure a perfect centering of each dischargenozzle relatively to the corresponding receiving-nozzle of the can or other receptacle engaged thereby. By reason of the liexible connection of the frameIwithitssupportthrough springs J said frame is alsoA capable of such slight horizontal or lateral adjustment as may be effective in an auxiliary way to secure a perfect registration between the cooperating parts.

From the foregoing it will be observed that by our present invention we are enabled to extend the capability and usefulness of multiple-cell filling-machines which havev a direct discharge through the bottoms of the cells, rendering the same equally capable of charging small-necked receptacles without any leakageor waste whatever. A machine of this type equipped with our present improvements is certain and reliable-in operation and effects a large saving of time over the common hand method of filling such receptacles individually7 now commonly practiced.

While our invention has been designed more particularly for use in connection with machines used for packing syrup and mo-v lasses and like commodities, yet its utility is by no means limited thereto; but it may with equal advantage be employed in the packaging of oils, paints, and any other liquid or mobilecommoditiesthat are put up and marketed in measured quantities and in receptacles of the class described.

It will be observed that the above-described means for supporting the longitudinal series of funnels upon the frame I, comprising the telescoping members K and L, provides a free vertical adjustment of the funnels relatively to their supporting-frame, such as would be desirable to prevent injury to the parts, in case in the operation of forcing the frame I and the nozzles h into registration with the receptacles G the lower ends of the nozzles h should contact the upper ends of the receivingnozzles g before the said parts became properly centered by the automatic adjustment of the frame I.

We claim as our invention l. In a lling-machine, the combination with a supporting-frame and a measuringtank superposed thereon, the latter comprising a series of measuring-cells having discharge-openings in their bottom walls, of a frame carrying a series of funnels correspond-- vcharge-openings in their bottom walls, of a frame carryingaseries of funnels corresponding in number and relative arrangement to the measuring-cells disposed directly beneath the latter, automatically-operating means for raising and supporting said frame normally in an elevated position beneath the measuring-tanlga'nd other positively-actu ated means" for depressing the same to carryl the funnels into registration with a series of receptacles to be iilled disposed therebeneath, substan-y tially as described.
