CONVEYER MECHANISM.

Application filed October 14, 1927.

A from the top of which the cartons are dropped ill) in succession, into the feed chute of the sealing or wrapping machine.

WVith this and other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the'appended claims.

Referring to the drawings:

Fig. 1 is aperspective view of a portion of the carton filling and closing machine; the 7 wrapping machine, and my Improved mechanism which is interposed between the same.

Fig. 2 is a top plan view of means forming part of the present invention for delivering the closed cartons successively from the closing machine to the conveying mechanism, the lower portion of the latter being also shown in this view.

Fig. 3 is a side view of the delivery unit of the improved mechanism.

Fig. 4: is a side elevation of the improved mechanism.

In the drawings, 1 designates the carton filling machine, 2 the carton closing machine and 3 the machine for applying a wax paper wrapper to each carton.

I These three machines form no part of the present invention, but the improvements are used in connection with such machines.

In using such machinery, a series of cartons 4. is fed along the runway 5, after the cartons have been closed, and it is at this point that the improved mechanism comes into play.

Such a mechanism comprises a throw-0E device 6, positioned at the delivery end of the runway 5, and provided at one edgewith a forwardly projecting flange 7, which functions as a stop to engage the end carton on the series. The throw-off device also has a rearwardly extending flange 8 at its other side Serial No. 225,089.

form of a bell-crank lever, one arm of which supports the plate 10,-carrying the flanges, and the other arm'll of which engages a retatable cam 12 which is constantlydriven in a clock-wise direction by a shaft 13 to which it is fixed.

A spring 14 has one of its ends connected to the bell-crank lever, and its other end secured to a fixed point on the frame of the machine, so as to move. the arm 11 toward the cam. A stationary abutment l5 limits the movement of the bell-crank lever in one direction.

When the throw-off device swings in the direction of the arrow, it throws the end carton of the series in an arc-shaped path, and into a short inclined chute 16. In order to steady such movement of the carton while it is travelling to the chute 16, the mechanism is provided with an arcuate friction plate 17, against which the thrown carton rubs on its way to flat position in the chute 16. This plate 17 is carriedby bolts or' the like i 18, which extend through holes in a supporting bracket 19, that is secured at 20 to the runway 5. Coil springs 21 surround the bolts and are. arranged between the bracket and plate 17 to yieldingly hold the latter in position. 7

As best shown .in Fig. 3, the throw-off device and arcuate friction'plate causes the cartons to stack up in the chute 16. i

The bottom of this chute is connected to the lower end of an inclined feed-way 22, the upper end of the latter beingconnejcted to the top of a chute 23 which leads the cartons to the wrapping machine.

The feed-way 22 is preferably formed of oppositely disposed angle iron tracks 24:, connected together at spaced points by cross bars 25. The lower ones of these cross bars are provided with guides 26 for the sliding bar 27 of an ejector 28. The latter reciprocates in the lower end of the feed-way 22, and acts to force the lowermost carton of the stack in the chute 16, up the feed-way 22. As a carton moves from the chute'16 on its first step up the feed-way 22, it is caught by pivoted latches 29 which act to hold the line of cartons as the cartons move up the feed-way 22. When the uppermost oneof the cartons in the feed-way, reaches the upper end of the latter, j

the pivoted latches.

it is pushed by the second uppermost carton, into the chute 23.

The ejector 28 is pivotally connected to a rod 30, which in turn, is connected to a bellcrank lever 31, pivotally mounted at 32, and rocked from any suitable mechanism by a rod 38.

The latches 29 are preferably mounted on pins 34, supported on the sides of the feedway 22, and coil springs 35 are arranged on these pins, so as to urge the fingers 36 of the latches, through slots in the sides of the run- Way.

It is believed from the foregoing description, when considered in connection with the accompanying drawings, that one may read ily understand the construction, but explaining the operation briefly, it may be stated that the throw-off device 6 is intermittently rocked on its pivot to throw the cartons from the runway 5, one by one, into the chute 16, where they .pile up neatly, into an inclined stack. The ector 28 reciprocating in proper timed relation to the movement of the throw-elf device, pushes the cartons one by one from the bottom of the stack, and marshals the same into an inclined row which is maintained by As the cartons moveup the feed-way 22, they are deposited one by one into the chute23, and are thus delivered to the wrapping machine. c

It will be apparent to those skilled in the art, that various changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.

What is claimed and desired to be secured by Letters Patent is:

2. Transfer mechanism as claimed in claim,

1, including friction means against which the cartons rub on their way from the throw-off device to said chute.

3. Transfer mechanism as claimed in claim 1, in which the throw-0H device comprises a movable plate having oppositely directed flanges at its side edges functioning as stops for the cartons.

4%; The combination with the delivery runway of a carton closing machine, of a throwoff device pivotally mounted and arranged to successively throw cartons from the runway to one side of the latter, a spring-pressed arcuate friction plate arnnged at the side of the runway and in the path of movement of the cartons thrown by the throw-off device to rub against the cartons as the latter are thrown, an inclined chute arranged below the friction plate to receive the cartons and stack them up, an inclined feed-way communicating with the lower end of the chute, means for feeding the cartons successively from the chute on to the feed-way, and latching means for supporting the cartons while they are on the feed-way.

In testimony whereof I affix my signature.

Patent No. 1,714,533. Granted May 28, 1929, to

' WALTER s. WEBER.

it is hereby certified that the assignee in the above numbered patent was erroneously described and specified as "Wm. H. Luden, Inc., of Reading, Pennsyivana, a corporation of Pennsylvania", whereas said assignee should have been described and specified as "Ludens, Inc., of Reading, Pennsylvania, a corporation of Pennsyivania", assignee by mesne assignments of the entire interest in said invention, as shown by the records of assignments in this office; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Office.

Signed and sealed this 18th day of June, A. D.. 1929..
