PETER RASMUSSEN, OF DENVER, COLORADO, ASSIGNOR OF ONE-HALF TO STEPHEN KNIGHT, OF DENVER, COLORADO.

MULTIPLE-GUIDE-ROW STACKED-CAKE RECEIVING AND ASSEMBLING- MACHINE.

Patented Nov.22,1921.

Application filed August 30, 1920. Serial No. 406,929.

To all whom it may concern:

Be it known that I, PETER RAsMUssEN, a citizen of the United States of America, residing at the city and county of Denver and State of Colorado, have invented new and useful Multiple-Guide-Row Stacked- Cake Receiving and Assembling Machines, of which the following is a specification.

My invention relates to a multiple guide row stacked-cake receiving and assembling machine, and the objects of my invention are:

First. To provide a machine that will receive cakes in stacked form and will confine them in separate rows and convey them where they can be easily and quickly removed from the machine in edgewise stacked groups and placed in shipping boxes.

Second. To provide a stacked-cake receiving machine having a plurality of adjustably widening or narrowing stacked cake guides, adapted to receive between them cal-res of different sizes, and

Third. To provide a stacked cake receiving machine that is provided with an upwardly inclined, vertically adjustable and counterbalanced endless belt that is hinged to the horizontal portion of said conveyer.

Fourth. To provide a'complete and thoroughly practical multiple guide row stackedcake receiving and assembling machine.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the improved machine.

Fig. 2 is a transverse sectional View thereof, on the line 22 of Fig. 1.

Fig. 3 is a side view of a portion of the forward end of the machine, the near leg being omitted for clearer illustration.

Fig. 1 is a plan view of a portion of the forward end of the machine, showing the plate for bridging the gap between the conveyer drum and the end of the conveyer supporting table.

Fig. 5 is a plan view of the mechanism for raising and lowering the conveyer drum and the inclined board which supports the forward portion of the conveyer, and

Fig. 6 is a fragmentary plan view showing the manner of hinging one end of the inclined conveyer-supporting table.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings:

The numeral 1, designates the supporting frame of my cake row receiving and assembling machine. 2, designates its cake receiving end, and 3, its cake discharging end.

At the opposite corner posts 4:, of the lower end of the frame, I rotatively mount in bearingsb, vertical rods 6, the lower end portions of which are threaded, and on these rods I threadedly mount yoke-shaped boxes in which a shaft 8, is journaled that ex tends across the end of the machine and on which a drum 9, is secured, on which is mounted one end of an endless canvas belt 10, the opposite end of which is mounted on a roller 11, that is secured on a shaft 12, that is iournaled in sliding boxes 18, that are mounted in a slideway 13 and the boxes 13, are adjusted to tighten the conveyer belt by hand screws 13 which pass through the ends of the slideways and through the blocks in the usual manner.

The bearings 5, are formed on metal bars 5 which are secured to the posts 4:, and the upper ends of the threaded rods 6, have rigidly mounted thereon, bevel gears 6 which mesh with bevel pinions 6 on a rod 6 which is journaled in bearing 6, also formed on the upper ends of the bars 5 One end of the rod 6 is provided with an operating hand wheel 6 by which the rod with its pinions 6 is rotated, and the gear 6 and rods 6, are thereby turned, by which the boxes 7, are raised or lowered, with the drum 9, which is mounted in said boxes.

The upper part of the'conveyer is supported at its angular turn by a roller 13 and an inclined. board underneath it, which will be presently described, and the lower part of the conveyer belt is supported on a roller 13 which is mounted on the frame as shown in Figure 1.

One end of the shaft 8, is provided with sprocket wheels 14, of different diameters, any one of which is adapted to be connected by a chain to a similar sprocket wheel on a driven shaftnot shownof the cake delivering part of a complete cake stacking machine, such as is illustrated in my issued Patent Number 1,217,845 dated February 27,

1917, and also in my pending application,

Serial N 0. 406,928 filed August 30th, 1920.

My present invention relates to improvements in the rear or cake row, assembling part of the machine, and is an improvement on my issued patent, including the improvements made in this rear end part to date. Upon the side rails 17, that are secured to thecorner end posts of the supporting frame portion of the belt merges into the horizontal portion, as will appear by reference to Fig.1. 7

The forward, ends of the inclined portions of the guides 21, however, are supported by standards 25, which are secured to supports on the forward GHCl'Of an inclined board 26, that forms a supporting table portion for the endless belt conveyer; slotted straps 27,

are secured to the side edges of this board 26, and bolts 15 extend through the slots of the straps, and into the boxes 7, which arrangement'causes the conveyer supporting board to be loweredfor raised with the boxes 7, and the drum 9, and the lower end of the conveyer 10,-sothat the hinged members of the guides will move simultaneously with theinclined portion of the belt when the drum Sis raised or lowered.

The guide bars 21, are preferably in the 'form of angle bars, and by sliding the supports laterally on'the rods 19, the space be tween'the guide bars 21, may be varled to suit the diameter of the cakes passing over the machine, so that the cakes are maintained in a uniform column of unvarying width duringthelr progress toward the discharge end of the conveyer 10. The guide bars are held at the desired position of ad- .justment by thumb screws 28, in threaded apertures in the supports 20, which are screwedagainst the rods 19, and. thus hold the supports, WltlliillGll rails, in the pos tion desired. A horizontal 7 board 29', is also placed under the horizontal portion of the 'conveyer.

I prefer-ably illustrate three sets of stacked cake confining guide bars in my present 1mproved machine, as my present. machine is adapted to be connected to the discharging ends of the cake stackln'g chutes illustrated in my pending application, Serial No. 406,930 iiled August 30, 1920.

Inasmuch asthe lower end of thecon veyer',with its three sets of cake guiding bars and its roller and shaft and the lower end of'the belt supporting board are too heavy to move upwardly easily when the hand wheel is turned to rotate the threaded rods that are threaded to the conveyer shaft supporting boxes, I provide the opposite sides of the frame and the conveyer with a counter-weight mechanism that is preferably constructed as follows:

To the side rails of the frame I mount rope sheaves 30, on, a short shaftor bolt 31, which is secured to the side rails, and extend a rope 32, over it, one end of which is secured'to the inclined conveyer belt supporting board '26, and the other end of the rope is secured to weight 33, which is heavy enough to permit the lower end of the conveyer to beraised easily by the hand wheel and cross-shaft that raises the shaft-supporting boxes of the lower end of the con veyer. r

' After the belt 10, has been placedonthe machine and tightened sufficicntly,.by ad-- justing the boxes l3', which support the I roller 11, further means are employed for taking up the slack of the belt, when the drum 9, and board 26, are raised or lowered,

and .thusmaintaining a uniform tension of the belt.

The means employed consists of a metal roller 34, having trunnions 35, which are supported in yoke-shaped brackets 36, which are secured to theunderedgcs of thelside bars 1. about midway of the length'of the horizontal table 29. This roller rests upon the under lap. of the beltlO, as shown in Fig.

1, and maintainsa uniform tension of the belt, at all times, as the inclination of the board 26, is changed, to meet requirements arising from the different characters of goods which are run over the belt.

' That half off the machine having the stationary horizontal belt supporting table 29, is the part from which the cakes are taken and placed in boxes by attendants, who stand on opposite sides of the machine. To

the side bars 17., on opposite sides of thispart of the machine, are hinged side boards 3'7, which are held in horizontal positions by arms 38, which are hinged at one end to the outer edge portions of the side boards, and their inner ends are bent at a suitable angle, and are provided with slots 39, which open through the said ends of the arms. 7

The middle and rear legs 40, of the machine are provided with headed bolts 41, whichreceive the slotted ends of the arms, and thus support the side boards in horizontal positions, These side boards support the cake receivin boxes and may also receive' the cakes, which are afterward placedin boxes. 'When the machine is not running, the side boards may be dropped to vertical positions, as shown by dotted lines, Fig. 2, so as to be out of the way, and this is accomplished by simply disconnecting the slotted ends of the arms 38, from the bolts 4L1.

It will be apparent that when the hinged board 26 is raised to approach a horizontal position, its free end will lie close to the face of the drum 9, and when the board is lowered, its free end recedes from the face of the drum, thus leaving a gap or space between the drum and the end of the board. It is necessary to bridge this gap for the following reasons: Cakes are supplied to this end of the belt 10, by a plurality of stackforining chutes l2, which are de scribed in my co-pending applications above referred to, and the discharge ends of these chutes rest upon that part of the conveyer 10, beneath which the gap occurs, and this part of the conveyeris supported from beneath, in the following manner:

A rod 43, extends across the front end of the machine, and its ends are supported on the boxes 7. A thin metal plate 4 1, of the width of the conveyer, is secured at one end upon the said rod by forming a roll upon the end of the plate and passing the rod through the said roll. The plate extends over onto the free end of the board 26, and between the board and the conveyor, thus bridging the gap between the drum and the end of the board, and supporting the conveyor, where the chutes rest.

In operation this machine receives cakes that have been stacked into rows in the stacking chutes of that part of a complete cake stacking machine that is positioned ahead of my present machine and that is positioned to discharge its stacked cakes between the adjustable guide bars of my present machine, and the endless conveyer belt conveys them in these rows in which they are discharged, in overlapping relation to each other, between its guiderails, as these three sets of guide rails are positioned to stand in alinement with the discharge ends of the chutes, a fragmentary view of which is shown operatively connected to the lower cake receiving end of my present cake assembling and removing machine, which conveys them in continuous stacked groups between their guide bars on top of the horizontal portion of the machines, whose operators standing on opposite sides of the machine, scoop each group of stacked cakes as it is conveyed in front of them, into edgewise stacked rows, and liftthem from the guides and machine and place them in ship-- ping boxes.

The object of raising or lowering the lower end of the endless inclined stackedcake-receiving machine is that some sizes and kinds of cakes retain the overlapping stacked form in which they leave the dis receiving portion is a very essential part,

and my invention contemplates its adaptation to any of the cake stacking machines in use, and especially cooperatively connected I to and forming a part of the cake receiving and dividing head end machine and also of the cake stacking chutes machine illustrated in my two pending applications herein mentioned.

My inventionprovides a simple practical machine for handling large quantities of cakes in stacked form so they can be readily removed by attendants and placed instantly in rOWS in shipping boxes, and while l have illustrated and described the preferred construction and arrangement of my machine, I do not wish to be limited to it as changes may be made without departing from the spirit of my invention.
