a n-sauna filed June 25, 192-3. Serial No. erases.

citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in an Olive-Stuffing Machine, of which the following is a specification, and which is illustrated in the accompanying drawings.

My invention relates to improvements in an olive stufiing machine for the production of what are known as stuffed olives or pimento olives and wherein the olives have the pits removed and the spacesfilled with a red pepper and cheese or other spiced compound in the form of a very stiff paste.

The object of my invention is to reducethe large amount of hand labor heretofore always used in the preparation of these olives, by carrying out the various operations on an automatic machine of simple construction and which will provide for controlling the amount of filler paste injected into the olives, and which will per mit of quick replenishment of the paste filler container when exhausted, and also an automatic machine of this character wherein all the features are actuated by a common driving element to insure permanent register of the co-operating parts;

I achieve the objects above mentioned, together with other desirable features, by the mechanismillustrated in the drawings accompanying this application and forming part hereof, and in which Fig. 1 is a front elevation of my complete machine. Fig. 2 is a plan view of the left hand end showing the paste filler container and gearing machine. Fig. 10 is a diagrammaticview to illustrate the automatic pressure feed for the paste container.

Fig. 11 is an enlarged cross section of the injector nozzles and sprockets and showing the paste passage and control within the hollow fixed shaft, and Fig. 12 is a full size view showing an injector nozzle positioned against a socket and over an olive, the olive and socket being drawn in section.

In all of the views, like parts bear similar numerals, and With further reference to Figures 1 and 2 my machine will be seen 'to consist or a long base 1 having a pair of bearing or shattsupporting frames 2 at one end carrying sprockets 3 and 4, and at the other end a double vertical frame 5 carrying sprockets 6, 7 and 8. V The standards 5 are as stated, double, being spaced for bearings for transverse shafts supporting the sprockets arranged as shown, all clear enough to anyone skilled in the art without further detailed description or other drawings.

All the sprockets mentioned are double, that is, there are two of each mounted spaced a short distance apart side by side, for revolution about common centers.

A doublestrand of chain 9 is threaded over the various sarockets as shown, and travels in the direction of the arrow actuating the several sets of sprockets simultaneously.

A motor 10 delivers power through worm gearing 11 to the shaft of the extreme right hand lower sprocket to actuate the machine, the chains referred to transmitting the motion to all of theother sprockets, and thus,

since all have a common means of actuation,

arrangement, etc. Fig. 3 is an enlarged cross \proper sequence of operation is assured.

ejecting or the pitting punches as they both have the same construction.

Fi 9 shows one form of device for refilling the pimento paste container of the To maintain the chains under proper working tension the upper pair of sprockets 6 are carried on bearings 12 form-ed to embrace and slide up and down on the standards 5 and the bearings are pulled upwards by a weight and pulley arrangement as indicated at 14 and 15, the the bearing plates may also be clamped to the standards 5 by the screws 16, being simply released once a month to permit the slack being taken u tnen re-tightened to prevent possible surging of the drive.

The chain strands run in a groove or guide in the base (as shownin Figure 3) and have riveted to and between them at spaced intervals, usually about eight inches, sockets 17 for receiving the olives. These sockets are detailed about full size in Figures 6 and 7, and are adapted to receive the lives tightly between spring and the chains travel at about. six or eight inches a second thus presenting from fortyiive to sixty sockets a minute for filling by an operative who separately places olive in each socket.

Attention may here be called to the fact that the springs are placed. on the sockets at an angle of about forty five degrees to the run of the chaiin as indicated in Figure 7, so as to leave aworking space for the thumband index linger of an operative positioned in front of and racing the strand of chain, as the thumb and index finger holding an olive for placing .in a socket then naturally assume the position of about forty-five degrees across the run of chain.

The sockets carry the olives over the sprockets 3 where the cam actuator. punches 19, spaced around the sprockets to match th socket intervals, punch out the pits, and then over the sprockets e where siuiilarly spaced injector tubes 20 inject the pimento paste into the olives from the reverse side from which the pit punches entered the olives. The stuffed olives then pass over the idlers 6 and over the sprockets 7 where the paste filler is smoothed and the olives ejected by the flat nosed punches 21, "falling into the receiving trough 22.

The complete operation of the machine will thus readily 3e understood. and some of the more important details will now be taken up.

The sprockets 'i" idle on a tired shaft 23 and carry between them the punches 21 actu ated by a stationary cam Q lon the tired shaft all as detailed in Figure 8, this view being a cross section taken between the sprockets and in which the punches are seen to be slidably supported in bearings 25 extending between and ii mild to both sprockets, a spr ng 66 around each rod serving to hold the cam roller 26 against the cam.

On the other end of the machine the sprockets 3 likewise carry a series of punches 19 for punching out the pits of the olives, ut since these punches are operated just the same as the ejecting punches described no further detail or description is required. The only dili'erence between these punches and the ejecting punches is that the latter are as large in diameter the hole in the socket will permit and are i 'T on the end so as to smooth oil the paste :iiller and also push against the edges of olive meatextending more or less within the hole and eject the olives without penetrating into the paste filler, whereas the pitting punches are con siderably smaller in diameter and prefersbly slightly cupped on the ends to better engage the pit.

Referring to Fig. 6, the olive socket w'll be seen to consist of a shallow cup 17 having olive retaining springs 18 projecting above it, and a central opening through which the pit is pu hed, surroiuiding the hole is a short tube 27 against which the olive is pressed by the operative and which cuts the olive shin and insures that the skin or meat wil not break away beyond its cutting limits when the pit is punched out. thus preventing a ragged appearance to the piniento filler.

The punches do not enter the olives lirough the sprock t rotation, but act posii y by the cam, thus they do not enter nor ca' e'the olives at an angle.

At the under side of the opening through the socket it is, at 28 slotted and funneledin direction of travel to permit the angular entry and withdrawal of the pimonto injector nozzles or tubes 20 carried by the sprockets l. The injectors receive their supply of pi mento in the form of a still paste from the cylindrical container 29 in which it is kept under a proper working pressure to force itthrough the piping and tubes. The paste passes from the container through the piping 31 to ahollow fixed shaft 30 around which the sprockets l and the injector tubes revolve.

The container is here shown as a single compression cylinder, but it is evident withoutv illustration that two or more may be used so that as one is emptied another may be cut into the line by suitable valves on the piping, and the empty one removed for filling, but I prefer to refill the container in place as given below.

To rigidly support the container cylinder in place I insert it into a heavy iron cylinder casing 32 which is permantly bolted to the base at This outer casing serves as a rigid base to carry the compression paste cylinder within it and also supports the bearings 3 1 "for the worm pressure teed gearing on top. The casing is slotted vertically to permit insertion and withdrawal of the lower paste outlet nipple extending from the paste cylinder for connect-ion by means of the coupling 36 to the piping 31.

A. feed worm 37 is mounted at the top of the outer casing on a shaft 38 for meshing with a wormwheel 42 on top of the paste cylinder.

The upper head of the paste cylinder is flanged to rest on the outer casing and is properly located thereon by the bolts ll.

The upper end of the paste cylinder also carries the wormwheel 42, this wheel is lined to a threaded plunger rod l3 for ding thereover but is not threaded thereto so that the wormwheel being turned by the worm will rotate the rod and screw it sp sli plunger rod 43 to rise I have the threaded.

downward through the threadedisplit nut 39 secured to the upper head iii of the cyl' inder.

The paste cylinder ma y be easily removed for filling it with paste, by simply disconnecting the coupling 36 and loosening the bolts 4:1. then sliding back out of engagement with the worm and liftin the cylinder bodily out of the casing but I prefer to refill the container when low, by attaching an auxiliary refilling cylinder to a branch l in the piping then opening the valve 17, closing the valve 48 and forcing the'contain er32 full from under its plunger through its outlet pipe 35. To permit the threaded nut 39 through which the rod'passes split as shown in Figure 5, so that by loosening the screws -19 and separating the halves 39, 39 of the nut, the plunger rod is free to back up through the cylinder when the latter is forcibly refilled from below the plunger.

A convenient refilling device is shown in 9 which takes the form of a simple I pressure pump as shown having an outlet 50 adapted to couple to the pipe connection 10 of the machine. 7

No particular importance attaches to the exact construction of the refilling device, as it may be similar to any of the well known grease guns with screw, lever or power arrangement for forcing its contents into.

the line and paste container of the machine.

Fig. 4 is a sectional view of the interior construction of the paste cylinder in position within its casing. The plungerrod 4:3

is shown threaded through the split nut 39 secured to the head 4.4 of the cylinder and connected swivelly at 4:5 to a plunger 46 for forcing the contents of the cylinder down and out of the lower outlet 35, thence to the piping and injectors.

To maintain a constant pressure in the cylinder at each injection of paste into an olive an automatic pawl and ratchet feed arrangement 51 of the well known type is secured to the end of the worm shaft 38 and is actuated by a crank link 52 pivoted to a gear 58 meshing with a larger gear 54 secured to the outer side of one of the sprockets 1, the ratios being such that. the feed will operate just as each olive is in position against an injector nozzle.

Fig. 10 is an enlarged diagrammatic view of the feed device, and it will be seen that the feed can be varied by sliding the pivotal connection 55 to any point along a'gibbed slot 72 in the outer face ofthe gear 53, also that the pawl 56 may be thrown back out of engagement to stop the feed in the usual manner.

The arrangement of the injector nozzles 20 in relation to the hollow fixed shaft 30 is best shown inFig. 11 an enlarged cross section through the sprockets l. The

sprockets revolve on the fixed shaft and are connected together at five places by arms 57 also loosely supporting five inject-or tubes rotatable valve or cutofi 61 for opening or closing the slot to control the amount of filler injected into the olives. The valve seats against a packing ring 62 against a shoulder in the hollow shaft and has an extension through the sl1aft---with an index wheel 63 for adjustment of the valve outside the frame 21 of the machine. 7

Felt packing rings 64 at both ends of the hub58 prevent oil working into the paste or paste under pressure from exudin The injector nozzles are tapered at the end 65 so as to enter and center themselves in each socket for injecting paste into the olives as the sprockets rotate and the tubes are successively passed over the feed slot 60-, the machine being so timed that the pressure feed mechanism 51 operates simultaneously \vith the registering of each injector tube with the slot. I

To give freedom to the nozzles to seat themselves properly in the sockets they are loose in the arms 57 and each is divided and with its divided ends joined with a. short section of rubber hose 67 clamped to the tube To prevent the possibility of the paste pushing the olive out of the socket a short endless rubber belt of considerable flexibility bears against the olives during the injecting period. This belt is indicated at 69 in Fig. 12 and its general position is shown in Fig. 1 of the drawings, it being carried loosely over two small ball bearing pulleys 70, and 71, supported by an extension of the frame 2, the friction of the passing olives serving to, move the belt;
