To allwhom itmay comm." I i part of a packeting machine with filling ap- Be it known that I WILLIAM county of Lincoln, England, have-invented new and useful Improvements in Fillmg Apparatus, of which the following is a specification.

This invention relates to filling apparatus for use in machines for packeting tea tobacco and other materials, and the sai in vention has for its object, to provide means whereby such materialscan' be rapidly and efl'ectively filled into bags, or containers,-

insuring the amount of material being fed into the bags, or containers, in the short time hitherto available for this operatlon and this has seriously and adversely afiected the utility of such apparatus.

According to this invention I employ two, or more, chutes for the purpose of delivering material to ba orcontainers, which travel in a straight fi ne, or path, the said chutes being arranged to travel with the bags or containers, so as to'increase the speed at which the apparatus can be worked, The

chutes are arranged above the line, or path of travel of the bags or containers, the necessary vertical, or downward and upward movements and the longitudinal, or forward and return movements of the chutes, being imparted thereto in any suitable manner.

.The chutes may be of any desired shape and size, for instance they may each consist of a tube, or channel, with a funnel-shaped top into which the required amount of material is suppliedby any snitabla means.

I Wlll describe with erence to the acnstru'ction in accompanying drawin cordance with this invent omfpremismg that the invention is not limited tothispartlcular construction. I Y Figures 1, 2 and 3. are respectwely a side elevation, an'end elevation, and a plan, of

H a sub jeot of the King of Great Britain, residingat Albion Works, Gainsborough, in the- 22, to the sli paratus accordance with this invention. F1g. 4 1s a side elevation of the chutes and operating levers,; showing the ends of the c utes introduced into two bags, or containers.

1, are the chutes fed'with material by the pipes 1' and connected,to a slider, or sleeve, 2, which is capable of sliding on a guide or spindle 3, supported at its ends by the arms .4 of bell-cranklever's which can turn on center pins 5 and 6 secured-to the frame 7 of the machine. The arms 8 and 9' of the said bell-crank levers, are connected by a rod 10, so that the said bell-crank levers are-actuated in unison. A prolongation of the arm 9 of one of the bell-crank levers is pivotally connected, by a rod 26, to the arm 11 of the bell-crank lever 12, to which motion is transmitted by a cam 13, on a shaft 14 which cam bears on a roller 15, carried by the arm 16 of the bell-crank lever 12. On the shaft 14 is a disk ,with a cam groove 17 in it, with which engages a .roller 18, carried by the arm 19 of .a bell-cranklever 20, the other arm 21 of which is connected by a rod der, or sleeve 2; 23 are bags, or containers, which are shown as being supported by a chain of carriers passing around wheels one of which is shown at 24 in the drawing secured to the shaft 25 which may be the main driving shaft.

The lower ends of the chutes 1, 1' are 0 such size as to allow of their enterin the bags, or containers, 23, and the said c utes may be connected together in any suitable way, the upper part of each chute being preferably of funnel form as shown.

By the action of the cam 13 and bell-crank -lever. 12 and its connections with the guide 3, the chutes are caused to descend and their lower ends to enter the bags, or containers,

which are then stationary beneath the said ends and material is delivered to the chutes tion, and at the same rate, as the bags, or

containers, the material being delivered to the bags, or containers, during such movement. The carrier then again comes to rest and at, or about, the same time the chutes are caused, by the action of thecam 13 to of the conveyer and the chutes should maintain a definite relationship with each other. In the case illustrated where two chutes are employed the conveyer, as already described,

es two consecutive forward movements during such time as the chutes are making one complete forward and return movement. The drive connection for obtaining this movement is shown in Fig. 1.

The carrier wheel 24 is intermittently partially rotated by a pawl 27 on one arm 28 of a bell-crank lever, mounted loosely on the shaft 25, the said pawl 27 engaging a ratchet-wheel 29 fast on the said shaft 25. The other arm 30 of the bell-crank lever is connected by a rod 31 to a crank-arm 32 fast on a shaft 33. The said shaft 33 is rotated by means of a toothed wheel 34 which engages a toothed wheel 35 on the shaft 14, the ratio of the toothed Wheels being as 1 :2 so that for every rotation of the wheel 35 and consequently, each complete forward and backward movement of the chutes, the wheel 34 makes two rotations and the carrier two consecutive forward movements.

From the foregoing description it will be understood that the time during which the material falls through the chutes and into the bags, or containers, can be made equal, or approximately equal, to two of the stationary periods and one of the intermittent forward movements of the bags, or. containers.

It will be readily understood that, if desired, more than two chutes may be similarly connected and operated.

What I claim is 1. In a machine of the character described, an endless conveyer adapted to carry receptacles to be filled and having at one point a rectilinear travel, means for imparting intermittent forward movement to said conveyer, a reciprocating filling chute arranged above the conveyer at said point of rectilinear travel and adapted to lead material to a receptacle carried by said conveyer, means for moving said chute forward with the conveyer during the filling oper ation and returning said chute to initial position during the .ensuing advance of the conveyer.

2. In a machine of the character departing intermittent forward movement to a said conveyer, a reciprocating filling chute arranged above the conveyer at said point of rectilinear travel and adapted to lead material to a receptacle carried by said conveyer, means for moving said chute forward with the conveyer during the filling operation and returning said chute to initial position during the ensuing advance of the conveyer, together with means for lowering said chute into the mouth of the container at the initiation of the filling operation and lifting it therefrom after the filling is completed.

3. In a machine of the character described, an endless conveyer adapted to carry receptacles to be filled and having at one point a rectilinear travel means for imparting intermittent forward movement to said conveyer, a plurality of simultaneously operated, reciprocating filling chutes arranged above the conveyer at said point of rectilinear travel and adapted to lead material to successive receptacles carried by said conveyer,means for moving said chutes forward with the conveyer during the filling operation and returning said chutes to initial position during the ensuing advance of the conveyer.

4. In a machine of the character described, an endless conveyer adapted to carry receptacles to be filled and having at one point a rectilinear travel, means for imparting intermittent forward movement to said conveyer, a plurality of simultaneously operated reciprocating filling chutes arranged above the conveyer at said point of rectilinear travel and adapted to lead material to successive receptacles carried by said conveyer, means for moving said chutes forward with the conveyer during the filling operation and returning said chutes to initial position during the ensuing advance of the conveyer, together with means for lowering said chutes into the mouths of the cooperating containers at the initiation of the filling operation and lifting said chutes therefrom after the filling is completed.

5. In a machine of the character described, an intermittently actuated traveling conveyer adapted to carry receptacles to be filled, a filling chute arranged above said conveyer and adapted to lead material .to a receptacle carried by said conveyer, means Ill for moving said chute forward with the conveyer and adapted to lead material to a receptacle carried by said conveyer, means for moving said chute forward with the conveyer during the filling operation and returning said chute to initial position after the filling operation is completed, said return movement of the chute being timed to occur simultaneously with the succeeding forward movement of the intermittently advanced conveyer.

7. In a machine of the character described, the combination 'of a rectilineally moving conveyer carrying receptacles to be filled, a plurality of simultaneously operated chutes mounted above said conveyer, and adapte to deliver material therefrom direct to said receptacles, a slider connected to said chutes, means actuated independently of said conveyer for reciprocating the slider, means for lowering the chutes, means for moving the chutes forward with the conveyer to permit of the delivery of material direct to the said receptacles, means for raising the chutes, and means for subsequently effecting the return movements of the chutes.

8. In a machine of the character described, the combination of a rectilineally traveling conveyer, a plurality of chutes mounted above and moved independently of said conveyer, a reciprocating slider connected to the said chutes and mounted on a guide, means for moving the chutes downward,

means formoving the chutes in unison with the forward movement of the conveyer, means for raising the chutes and means for veyer, a reciprocating slider connected to the chutes, a guide carrying said slider,

means for moving the guide downward,

means for moving the chutes in unison with the forward movement of the conveyer, means for moving the guide upward, and means for subsequently effecting the return movement of the chutes.

10. In a machine of the character described, the combination of a rectilineally traveling conveyer, a plurality of chutes mounted above and moved independently of the conveyer, a reciprocating slider connected to the chutes, a movable guide carrying said slider, means for moving the guide downward, means for moving the slider and chutes in unison with the forward movement of the conveyer, means for moving the guide upward, and means for subsequently eifecting the return movement of the slider and chutes.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM ROSE.
