FLoUa-PAoKER.

SPECIFICATION forming part of Letters Patent No. 366,167, dated July 5, 1887.

Application filed February il, 1886. Serial No. 191,348. (No model.)

' which the following is a speciiication.

This invention relates to an improvement in,

that class of flour-packers which are provided with a packing tube containing a device whereby the flour is forced down into the barrel, sack, or other package, which is placed uponxa receding platform whose downward movement is automatically arrested when the desired quantity of flour has been packed.

The object ot' this invention is to render the machine easily portable and more etiicient and convenient in its operation, and to provide' means for regulating the packing-pressure with great nicety.

My invention consists to that end of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

'In the accompanying drawings, consisting of three sheets, Figure 1 is a sectional elevation of my improved flour-packer. Fig. 2 is a fragmentary sectional elevation at right angles to Fig. 1, on an enlarged scale. Fig. 8 is a vertical sectional elevation of the movable bearing and shaft. Fig. 4 is a fragmentary vertical section of the upper portion of the packing-tube. Fig. 5 is a horizontal section in line w so, Fig. 4. Fig. 6 is a vertical section through one of the supportingposts and connecting parts. Fig. 7 is an elevation, on an enlarged scale, of one of the helical springs and connecting parts. Fig. 8 is a side elevation of one ofthe catches whereby the platform is held down when the paekingpressure is removed. Fig. 9 is a horizontal section in line yy, Fig. 1, on an enlarged scale. Fig. 10 isa sectional elevation .showing amodified construction of the packing-tube.

Like letters of reference refer to like parts in the several figures.

A represents the lower end or dischargespout of the stationary flour-bin, and Al the receiving-hopper of the packer, connected by arms a with the upper ends of the posts ofthe packer. The upper end of thehopper A fits against the lower end of the bin A, as shown in Fig. l. l

A2 represents a movable band attached to the outer side of the hopper A by clamps a', so as tolap over the ljoint between the hopper A and the bin A and prevent the escape of ilour through said joint. Upon releasing the clamps a the band A2 is dropped downxthere by disconnectingthe hopper from the bin and permitting the packer to be moved underneath another bin, to which it is connected by the band A2, in the abovedescribed manner. By this means one packer may be used to pack flour from several bins.

The hopper Ais provided with a valve or slide of any suitable or Well-known construction for cutting off the supply of flour at desire.

a represents the tubular throat of the hopper forming the upper stationary portion of the packing-tube, and B the lower portion of the packing-tube detachably secured to the throat al by bolts b.

C represents a bevel gear-rim which surrounds the throat ai and turns upon supports c attached to the throat. These supports may be rollers or short bearing-pieces, or a ring which extends around the throat.

. D represents a rotary tube which surrounds the stationary tube B, and which is detach ably secured to a collar, d, which is attached to the under side of the gear-rim O. The tube D extends downwardly beyond thelower end of the packing-tube and is provided at its open lower end with a cross-piece, d', to which is secured a vertical shaft,` d2. The latter`extends upwardly into the packing-tube B and carries packingaugers E i. The upper end of the shaft d2 is journaled in a cross-1 )iece,d*, secured in the packingtube.' Thelower crosspiece, d', may, be constructed in the form of a packing-auger, if desired. By turning the gear-rim C the tube D and the shaft dN and angers E E secured thereto are turned, so as to force the iiour out of the packing-tube B into the barrel or other package. Upon disconnecting the packing-tubcB from the throat a and the tube D from the collar d the flourforcing mechanism can be removed andreplaced bya similar mechanism of smaller size, if desired.

In the construction represented in Fig. 10 the packing-tube B and the central shaft are IOO omitted and the packing-angers are directly attached to the rotating tube D. This construction is simpler than that shown in Fig.

1, and is especially adapted to pack barrels,

as the latter are not liable to turn with the rotating tube. l

f represents the horizontal drivingshaft, journaled in stationary bearings and provided at its outer end with a tight and loose pulley, F F', and .at its inner end with an internallytoothed gear-wheel, f.

g represents the movable drivingshaft ar ranged near the inner end of the driving-shaft f and provided at its outer end with a pinion, g', which engages with the gear-wheelf and at its inner end with a bevel-gear, g2, which engages with the gear-rim C. The shaft gis journaled eccentrically in a bearing, Q,which is capable of turning` in its seat in the frame of the machine, so that by turning this bearing the shaft g is raised or lowered, thereby throwing the pinion gout of or into gear with the wheelf. r

HH represent the hollow vertical posts of the main frame arranged on both sides of the packingtube and connected at their upper ends to the arms ct, which support the hopper A.

I represents the receding platform, composed of horizontal side pieces connected preferably at the rear of the machine bya cross-piece,`I, and provided with upright tubular posts I2, which guide the platform in its vertical movements upon vertical rods t' fi. The latter are secured with their lower ends to the base of the machine. The upper end of the rod t' is secured to the post H by a bracket, t, and the upper end of the rod t" is secured to one of the arms a.

j represents spiral springs surrounding the posts H H and resting with their lower ends upon collars j', which can be adjusted vertically on the posts for regulating the tension ofthe springs.

.I represents crossheads, which are secured with their inner ends to the tubular posts I2 of the platform and which embrace with their outer ends the posts H H and bear upon the upper ends of the springsj, so that the latter are compressed as the platform is lowered.

k represents chains or ropes secured to the cross-heads J an'd running over pulleys k', which are attached to the posts H H.

K represents weights secured to the end of the chains or ropes k in the hollow posts for the purpose of counterbalancing the weight of the truck and platform.

Z represents rackbars secured to the lower ends ofthe postsH H' and extendingnpwardly on the inner sides ofthe posts.

L represents spring cases or drums turning upon arbors Z and provided at their peripheries with gear-rims which engage with the rack-bars Z.

m represents a helical spring arranged in each ofthe drums L and secured with one end to the arbor Z and with the other to the drum,

' so that the spring is wound lup as the platform is lowered. The arbors Z" are secured to sleeves M, which are attached to the tubular posts I2 by set-.screws m', so that the toothed drums can be disengaged from the rackbars when not required for use by turning the sleeves lVI upon the posts I2.

N represents spring-cases provided with similar helical springs 'and turning upon arbors n, which are secured to brackets n. The latter arc attached to the arms a of the main frame. The spring-cases N are connected'with the posts l2 of the platform by straps a2 in such mannerthat the springs are wound up as the platform is lowered.

O represents the vertical shifting-rod guided with its lower end in an opening in the base of the machine and connected at its upper end to an arm, O', which slides upon the rod t above the tubular posts I2. The arm O is connected by a rod, O2, with an arm, l?, which is secured to the bearing g3 of the shaft g, so that by raising the shiftingrod O the arm P 'is swung upwardly and the bearing g3 turned in such manner as to engage the pinion g with the wheel f', while by lowering the rod. O the bearing is turned in the opposite direction and the pinion g is thrown out of gear with the Wheel f.

p represents an arm, which is secured to the rod O below the platform in such manner that the latter comes in contact with the arm pand shifts the rod and throws the shaft g out of gear when the desired quantity of flour has been packed. As the platform approaches the upper limit of its movement the post I2 `strik es against the arm O', lifts the latter, and throws the shaft g into gear when the platform reaches its uppermost position, thus starting the packing mechanism automatically.

Q represents the truck, which is placed upon the platform I, and which supports the barrel, sack, or other package into which the flour is packed. The platform I is provided with rollers q, which facilitate running the truck upon and from the platform. The truck is provided with wheels g', so that it can be easily moved on the iioor of the mill.

R represents catches pivoted to the base of the machine for securing the platform I in its lowest position. Each catch R is provided with an upper claw, r, and a lower claw, 1'. The platform I is provided on its under side with inwardly-projecting noses s, which engage with the catches R. The catches R on both sides of the machine are secured to the same rock-shaft r2 and assume a backwardl inclined position when the platform is elevated, as represented in Fig. 2. When the platform has nearly reached its lowest position, the noses s strike the lower claws, r, ofthe catches R, whereby the latter are turned for- `.vardl y so as to engage the upper claws, r, over the noses s, as represented in Fig. 8, thereby locking the platform inposition and permitting the truck Q with the package of flour to be removed from the platform.

r3 is an arm pi'voted to the base of the machine and connected with one of the hooks It by a rod, t, which is provided with a spring, t', whereby the rod is rendered extensible. W'hen the package filled with flour has been removed from the truck, the latter is moved back upon the platform. Vhen the truck has nearly reached the proper position upon the platform, the rear edge of the truck strikes the arm if and swings the latter backwardly, thereby swinging the catches R baekwardly and releasing their upper claws, r, from the noses s. The platform is now elevated by the reaction ofthe springs, and when it has nearly reached its upper position the packing-angers are automatically set in motion, as above described. Vhen the platform approaches its lowest position and the catches It are swung forwardly, the truck bears upon the arm i' and prevents the latter from moving with the catches It. rlhe spring t permits the arm fr3 -r to be held back by the truck, while the catches It move forwardly and interlock with the noses s. As soon as the truck is removed from the platform the arm r3 is drawn forward by lthe spring t. The catches R are held in engagement with the noses s by the upward pressure which is exerted upon the platform by the compressed springs. When a shorter package is to be packed, the noses s are removed and replaced by correspondingly-longer noses, which depend further below the platform and engage with the catches R at the proper time.

In my improved packer the pressure of the flour in the bin is exerted directly downward upon the iiour in the barrel or other package, and assists materially in packing the flour.

Either of the spring devices which resist the downward movement of the platform may be disconnected, or two or all of them may be used simultaneously, as the size of the package to be packed may require, thereby affording ready means for regulating the packingpressure.
