MACHINE FOR ARRANGING RECTANGULAR ARTICLES IN PAIRS.

Specification of Letters Patent.

Patented A11 9, 1910.

Application filed June 1, 1909. Serial No. 499,482.

To all whom it may concern:

Be it known that I, HERMAN A. KREr'r, a citizen of the United States, residing at Chicago, county of Cook, and State of Illi nois, have invented a certain new, useful, and

Improved Machine for Arranging Rectangular Articles in Pairs, of which the following is a specification.

My invention relates to machines for arranging articles of a rectangular form in pairs preparatory to and to facilitate expeditious packing thereof.

The object of my invention is to provide a machine of the character mentioned especially designed for use in the arrangement of bars of soap in the manner stated preparatory to the packing thereof for shipment.

A further object is to provide a machine as mentioned which will be entirely automatic in its operation and which will be strong and durable and of comparatively simple and inexpensive construction.

Other objects will appear hereinafter.

With these objects in view my invention consists in a machine characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter fully described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a perspective View of my device in its preferred form, Fig. 2 is an enlarged detail of one of the rollers over which travels an endless belt embodied in the machine, Fig. 3 is an end elevation thereof, Fig. 4 is an enlarged detail of a cam wheel included in the machine, and Fig. 5 is a transverse section taken on the line a: an of Fig. 4.

Referring now to the drawings, 1 indicates a supporting framework in the upper end portion of which is rotatably mounted a horizontally extending shaft 2, the same being driven by any suitable means (not shown) preferably, although not necessarily, through the medium of the pulley 3.

4 indicates an endless belt traveling over rollers 5 and 5 mounted respectively in the upper portion of the vertically extending bars 6 of the framel, and in the rearward end portion of horizontally extending arms 7 rearwardly projecting from said bars of said frame. A pulley 8 fixed to the shaft of the roller 5 and a belt 9 traveling over said pulley and a pulley 1O fixed to the shaft 2 effects an operative or driving connection between the latter and the belt 4. However, I do not wish to limit myself to the precise driving connection shown inasmuch as a chain and sprocket or other suitable connection might be incorporated if desired. In order to insure a positive and certain driving of the belt 4: by the rollers 5 and 5, I preferably provide at either of the extremities of each of the latter, sprocket- Wheels 11, traveling over, and extending between, which are chains 12 to which are suitably secured the longitudinal edges ofsaid belt.

Such connection, it is evident, effects the purpose above stated.

Suitably secured, preferably to the upper cross bar of the frame 1, is a plate 13, the same being so arranged that the vertically disposed lower end portion thereof is positioned directly over the roller 5 and midway the extremities thereof. Reciprocally mounted in the upper end portion'of the frame 1, preferably in slotted lugs 14 depending from the upper cross bar of'said frame, is a horizontally extending rod 15. Carried by said rod is a blade 16 so positioned thereon as to be reciprocated transversely of the horizontal central line of the belt at equally distant either side thereof, the entire extent of such vibration of said plate being slightly greater than the length of the plate 13. In order to effect intermittent reciprocation of the rod 15, a vertically extending arm 17 rockingly mounted upon the outer extremity of a supporting member 18 secured to and laterally projecting from the frame 1, is'provided. The upper extremity of said arm being in pivotal connection with the outer extremity of the rod 15,-the lower extremity thereof engaging the irregular groove 19 in a cam wheel 20 carried by the shaft 2, the stated reciprocation of the rod 15 is evidently effected.

Extending in vertical alinement with the belt 4, the rearward extremity thereof being preferably secured to the lower end portion of the frame 1, is a guide receptacle 21 rectangular in cross section, and formed preferably of metallic strips 21 supported at intervals by rectangular frames 23. Having its upper extremity communicating with the forward extremity of the belt 1 and its lower extremity with the guide receptacle 21 is an inclined chute 24-ofa width at its 1 upper extremity the same as that of said belt and at its lower extremity equal to that of said receptacle. Flanges 25 are provided at the longitudinal edges of said chute and a similar flange 26 is provided midway said flanges25 which divides the upper surface of the chute into two independent passages 27 of equal widths. v

Having its lateral edges slidably mounted in channels 28 suitably secured in the receptacle 21 is a preferably rectangular member 29. A connecting rod 30 having-its forward extremity pivotally secured to the member 29 and its rearward extremity suitably connected to a crank 31 formed in the shaft 2, is evidently adapted upon the rotation of the latter to impart reciprocatory motion to said member 29. The latter is so mounted in the receptacle 21 that, whenin a position at the rearward limit of its movement, as shown in Fig. 1, the forward edge thereof will be disposed in a vertical plane rearward of that including the forward edge of the chute 2 1, for reasons which will be obvious from the following.

In operation, the device is preferably arranged with the rearward or outer extremity of belt 4: positioned adjacent a vmachine which deposits rectangular bars of for instance soap, in longitudinalalinement centrally u on said belt. Such bars are carried forwar plate 13, the latter actin' as a stop therefor. Upon reaching suc' position successive bars, because of the blade 16, are alter- I nately forced to the right and left and thence carried by the belt 4; and delivered into the passages 27 of the chute 24-. The; same descend said chute and are directed for deposition into the receptacle 21 7 directly forward of the member 29. Thereciprocation of the member 29 is so timed that, upon a pair of bars being deposited side by side in the guide receptacle, said member will travel forward'forcing said bars forwardly in the receptacle to such an extent as to permit of the deposition of 'a succeeding pair of bars therein upon thereturnmovement' of said member. Thus it willbeseen that, by

"the-provision of the mechanism described,

'the preferable form of my'machine I do not "wish to' be limited thereto as there might be many changesmade in the'details of con- "structi'onand arrangement of parts without departing from the spirit of the invention;

comprehended within the scope. of :the appended'claims. And although I have deby said belt until they abut the signed my device with special reference to its use in connection-with the packing of soap I may use the same in the similar arrangement of any other articles to which it is applicable.

Having described my invention what I clalm as new and desire to secure by Letters I atent is:

1. In a machine of the class described, the combination of a chute, a guide'receptacle in communication with the lower extremity of said chute,means for conveying and delivering objects to said chute, means cooperative with said chute and said conveying means for causing the objects carried by said con veying means to be deposited in p airsinto said receptacle, and means for forcing forwardly in said receptacle each pair of objects deposited therein, substantially as described. V
