The same is placed iii-position on platform 6 in the machine, by opening-f the door 8 of the casing ror cylinder 1,said

door as shown in Fig. lhaving hinges 9.'

Each receptacle as emptied of its contents,

is removed through saididoor and" replaced by anew one.

- The lifting'platform' 5 may b lmis'edena lowered in any suitable mannerand, ashere shown, this/is accomplish'ed'by the" use of lifting screws 10and' 10': "one of these screws, to wit, 10', is the main lifting screw and it has 'a spline 11 therein, in which a key 12 travels, said key 'projectingfrom the the upper portions of saidscrews are pro vided with steady bearings 15 on the upright frame, members 4,- which',as before stated, unite the baseplate 2 andrthe upper sprocket wheel 13 of the lifting platformfi.

The lower ends of the said lifting"s'crews have bearings14' in the base plate "2 and frame member 3. The main lifting screw 10 extends upwardly and has a bearing 16 in an extended part 16 of the said'zframe 3.

The container 1 is rigidly mounted upon the revolving platform 6, and, in the present instance, is clamped against a semi-circular chuck 17 that standsvupright on said plat- 4 form 6, and which is rigidly secured to said tightened around the front ofthecan to clamp the same firmly. againstfsaid chuck' 17 by means of eccentric hooks 20 which, are

pivoted to one of said straps and hook over platform 6 or made a part thereof, as shown in Fig. 15. The inside or clamping surface of, said chuck is slightly smaller than the pins 20 on the other, as shown Fig.- 2. It will be understood that any suitable means may be employed for holding the can I effi cientand may be employed forthis purorcontainer' 7 firmly on the revolving platorm .6. The means above described are pose" 1 .The revolvlng platform 6:1sprov1ded with rollers which travel on a tracker 'circular raised portion the liftingplatform 5 i As shown n form 6 within a sleevei24sfijou'rna-led "in' the platform 5. On the;underside-of saidre- I rigse aide-ape eat jects downwardly fro1n':said. ,:revolving ;platvolving platform 6, a ratchet wheel 25 is secured. A pawl 26 engages said ratchet of the -sleeve 24. The sleeve 24 is enclosed by-theh-ub of the lifting platform 5 the circumference of which is provided with openings to'receivethe lifting screws before referred to. Attached to the sleeve 24' is .a sprocket wheel29 the hub of which is enclosed by a retaining'plate 30 which is secured to the sleeve 24 by a key 28. The pawl 26 functions in connection with the ratchet wheel25 when the can orcontainer is being elevated, to revolve said can, but, the said pawl 26 rides over the teethof said ratchet wheel when the can or container is being lowered. During this period the ratchet wheel 26 remains stationary through the control of a holding pawl 31 pivoted to a part of the lifting platform 5 and held in en agement with said ratchet by a spring 32; The sprocket wheel 29 is driven by a chain 33 from the sprocket wheel 13, said sprocket wheel being heretofore referred to, and the same being driven by the main lifting' screw 10. The upper end of the said screw, which as before stated, has a bearing 116 in the upper frame member 3, has a bevel gear 35 fixed to it which meshes with a bevel pinion 36 on the main driving shaft 37; The shaft may be actuated in any suitable manner, but in the present machine it is operated manually from a crank handle 38; The main driving shaft 37 is provided with bearings 39 and 40 on the upper frame member 3, and from the foregoing description it, will be seen that by rotating the shaft 37 ,the can, or container, 7 will be elevated by the lifting platform 5 through means of the lifting screws 1010' and revolved by platform 6 rotated through the means shown in Fig. 9 of the drawings. 1

Lifting screwlO has been referred to as the main lifting screw merely because it recei'ves the power from shaft 37 and is made longer than the other two. The power is transmitted to the two other screws from a sprocket wheel 34 fixed t0 the lower end of said screw 10, and similar sprocket wheels 34 fixedlon screws 10, all of which wheels are connected by a sprocket chain 68.

During the simultaneous rotation and elevation of the can or container the lard or other commodity therein contained is removed fromthe mouth of the can by means which engages the lard and elevates it into a discharging tube 4C1. The discharging device by whichthematerial is thus elevated -or*"removed from the can, which is herein- I termed a pump, may take various forms and the" form selected for the present machine is illustrated in detail on Sheet 6 of the draw-' 'ings. 4

As there shown, it consists of two elon-- gated toothed members 42 which are mounted upon shafts '43 having bearings in the ' end plates 45 and 46 attached to side plates 47, which parts, together'with the said toothed members 42- may be said to constitute the pump. The united parts 45, 46 and 47 are attached by bolts 48 to the bell end 44 of the discharge tube 41. The ends only of said toothed members 42 are secured to their re spective shafts, other portions of said gearsbeing chambered out around the shafts, as shown in Fig. 10, to decrease weight; The lower "end of the discharge tube 41 is supported upon the bell end 44 which maybe inthe form of a'casting as may also the parts which house the toothed members 42. Projecting from. one of the side plates 47 is a scraper or blade 69 which is maderigid thereto and scoops the lard into thespace adjacent to the teeth of the members 42 the can or container is rotated andelevatedr From Fig. 2 it appears that :the elongated toothed members 42, which constitute the pump as before stated, are of a length which extends approximately from the center of the can to the inner circumference thereof, so that when the can is rotated the entire contents thereof is engaged by the rotating toothed members. Owing to the increasing radius of the body of the lard or other commodity within said receptacle from the center to the circumference thereo'r'. if provision were not made the pump or toothed members 42 would discharge the lard unequally, therefore, the said members are tapered outwardly from their inner ends by the said teeth being cut down to the pitch line at the center and gradually given their full length at their out-er ends. The said elongated toothed members 42 are driven from the main driving shaft 37 through means of a sprocket chain 47 which connects with a sprocket wheel 48' loose on said shaft 37,

.The bevel pinion 36 is integral with a sleeve which is pinned to the shaft 37 (Fig. 8) and fronfsaid sleeve an arm 71' projects and supports aratchet pawl 72.

Looseon the shaft 37 is'a' ratchet wheel 73 that is engaged by said pawl and joined to said ratchet wheel is the upper sprocket wheel 48" connected by the chain 47 itoa lower The transmission gear 51, on the same "axis with spree-Let wheel 49 meshes with a pinion 52 on a projected end of one of the shafts of the elongated toothed memberes 42,7115; shown in Fi 13. The shaft of the gear 51 is supported on an extended part 53 of the end plate 45 at the bell end 44 of the cischarge tube.

1 It will be understoodthatin the elevation of the container T the contents thereof are removed by the pump as the same. iselerated and that the operation may *heflconsprocket wheel 49 on a short shaft 50.

tinuous or intermittent. After the contents have been completely removed by the complete elevation ofthe container the lifting and revolving Jlatforms, v5 and 6, and the container are lowered by a" reverse movement of the main driving shaft 37. During this movenientit is desirablev that the pump, members 42 remain stationary, and there volving platform 6 [shall remain stationary as to rotation. This is accon'iplished in ref? erence to the platform 6 through means of the holding pawl 31, as shown in. Fig. 6, and before referred to. The pump members 42 are prevente similar holdingpawl 54, (F 12), which is pivoted at'the bell'end t e discharge tubeand engages theteeth ot the gear 5].. This pawl' is held in such engagement by a spring 55 is also the pawl 31 by. a spring cr sim-ilar character. Therever'se operation of the main driving shaft therefore, has no effect on-the pump member, andthe revolving platforin other than to lower the latter.

The discharge tube includingflthe bell end thereof is firmly supported .in the position shown in Fig. 2 by a clamp consisting of two parts 56 which embrace the'upp'er portionof the tube at the upper frame member 3. The said parts 56 are united by bolts as shown in Fig. 3, and have extensions 57 and 58 which are bolted to the upper frame member 3 and thereby made firm. The up-' per end of said dischargetube is fitted with a ring or open casting 59 above which is placed a delivery cup 60, said cup. being hinged at 61 to the casting 59. The said cup occupies: an inverted position and has a bandle portion 62 by which it is moved on the hinge '61 to discharge the contents thereof after the desired quantity of-lard or other commodity has been discharged thereinthrough the discharge tube 41. On theinterior of the said cup there is a plate 63 of equal diameter with the interior of the cup.

This plate is shown inthe lower position in dotted lines in Fig. which indicates that the cupisempty. A plunger 64, also shown partly in dotted lines in F 2 is secured to the center of the plate 63 and extends'outwardly through an opening in the top of cm rotating by means of a the cup, the extended end being provided with a head 65 that may be pressed by the hand 1nd1s'chargn1g the contents of thecup into a suitable receptacle such 'asmay be desired to place the amount of measuredmate rial there n. The said measuring cup is such.

as that shown and described in the former patent hereinbefore referred to, and it is thought unnecessary to give any further description thereof. As the cup is shown in Fig. .2 it is immedi ely abot'e the discharge endof the tube 41 'and when the machine is operated by turning the ciwnk handle 38 the lard or other commodi is forced up through the tube 41 and into the cup 60. 15c

As the contents enter the cup itforces the plate 63 upwardly and therewith the plunger 64 until the requisite amount of the material is delivered to said cup; When this is done the cup is swung to oneside bythe handle 62 and the commodity received. by .the cup is discharged therefrom by-pressing downwardly on the plunger 65. The tube ll, is providedwith a surrounding cooling space orja'cket 66 withopenings 67 at the upper and lower ends thereof for an air or-water pipe to communicate therewith,

While I have with some minuteness described the various structural features, it is to be understood that these may vary more or less within the knowledge of the skilled mechanic, without departing from the broad underlying principles ofthe invention."

The discharge device, or pump, may take various forms but have found the'gear pump herein shown and described to be well adapted forthe removal of the contents of j the container. By;cutting down the ads dendum of the teethfrom a full tooth on the left end of the gears to about the pitch line at the right end, one half of the volume of the material is removed during one revolution of the gears." The volume removed at I, tainer. Kegs in which lard is also [packed 0 tion what I claim as new and desire to seeach revolutionand lifting of the container may be calculated so that the material may be fed to the gear pump in the ratio at which the pump will dispose ofit.

The machine has been described-in connection with a cylindrical form of container 7 in which lard is usually packed by the packing establishments. It is to be understood, however, that the machine isnot lim-- ited to the handling of this form ofconmay be put through the machine with like effect. In that case it would to change the position of the tube 41 to accommodate the the form of thekeg. For example, the mounting of the said tube would necessarily discharging have to be 'of a character that wouldpermit of the pump being swung more or less outwardly from the perpendicular position shown in Fig. 2, to reach the rounded form of the keg.

In the case of cylindrical cans or containers of varying diameters, the discharge tube and gear pump may beadjusted'laterally in a perpendicular position by means of the oblong openings in the clamp extensions 57 and 58, as seen in Fig. 3.
