lj Substitute for abandoned application Serial No.` 465,387, 'med April 29, 1921. This application filed August 25, 1924. Serial No. 733,999.
To all whom t may concem:
Be it known that I, EDWARD F. FOSTER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Labeling Machines; and I do hereby declare that the following is a full, scription thereof.
My invention relates to the preparation of individual articles or packages preparatory to offering them for sale and particularly to labeling and selling of such articles or packages in such a manner that they may be identified as a product of the original manufacturer and so sealing the saine that the genuine character thereof is established and is impressed on the mind of the customer.
It is one of the objects of my invention to provide a simple, effective and durable machine by which small, flat labels or seals may be aflixed to 'Wrapped articles of uniform size such as cakes or tablets of soap, when passed through the mechanism provided by my invention will accurately engage and control moving parts of the machine so that the labels or seals will be accurately placed in position on each package; also-to provide storage devices by which a quantity of the labels may be held in proper relation on each package; also to provide storage devices by which a quantity of the labels may be held in proper relation to the label aiixing part of the machine and also to provide means by which the labels are accurately removed4 one by one from the storage devices moistened and transferred to the point at which they are to be affixed and securely placed on the article to be labeled. p
My invention further includes details of construction by which the different movements of the machine are adjusted and by "which they are made to Work in harmony with each other.
The principles of my invention are illustrated in the drawings, in which Figure 1 is a side elevation of my improved machine.
Figure 2 is an enlarged vertical section thereof on the line 2 2 of Figure 1. n
Figure 3 is a vertical section on the line 3 3 of Figure 2.
- Figures 4 and 5 are further enlarged clear, and exact de- (i is a section on the line 6 6 of Figure 8 is anenlarged view of an airv regulating device. y
#Further describing my invention with reference to the drawings in which like characters of reference .denote like parts throughout, 1 is a substantial base or foundation upon which are mounted the side supports 2. A plurality of boxes 3 is slidably mounted vin the slots between the guideways in said supports formed by the upwardly extended -members 4. Upon the inwardly projecting ends 5 of boxes 3 are mounted upward extensions 6 which should be secured in place by means of straps 7 extending around said boxes or by other suitable means. Cross pieces 8 are secured to the tops of extensions4 and between said cross bars and boxes are included springs 9 to hold the latter resiliently in their normal positions. A shaft 10 having interrupted axial openings isextended through the bearings 3 and, except for slight rotation as hereinafter described, it is non-revolubly mounted therein. The central portion 13 of said' shaft should be tapered to receive a correspondingly internally tapered hub 14 of a Wheel constructed as hereinafter described. In order that the said hub may be given proper adjustability against air leakage and yet be permitted to revolve freely on said shaft the latter is threaded and provided with the nut 15 and lock nut 16. The said hub 14 is provided With radial arms or spokes having the Walls 17 and the tubular openings 17, 17h, etc. Said tubular openings lare continued through the hub 14 and extended outwardly through the rim 18 upon which they are spaced at equal radial distances from each other. The external openings should be continued above the periphery of the wheel by small distances as indicatedby the plate 19 and the latter is preferably provided with a multiplicity of holes 20. An opening 2l is placed in the wall of the tubular shaft 10 in such a position that the openings in the spokes as they revolve about it will .be successively presented thereto. At a point approximately opposite to the openings 21 there is a the line 4 4 and 5 5 of Figgroove 23 Vin the shaft which extends transversely of the wheel and longitudinally of the shaft and is connected with the axial opening l2 in the shaft by which communication is made with the outer air. At the upper part of the machine upon the extensions is mounted a transverse yoke 25 supporting tlre tubular structure 26 within which are placed the labels which are to be affixed by operation of the machine. The said tubular structure has a longitudinal opening 27 as illustrated in Figure and it is enclosed by the adjustable clamp 28 and bolt 29 whereby the diameter may be slightly varied as desired. At the lower end of said tube are provided flanges 30 upon which the circular labels may be and normally are supported. The said yoke is adjustably mounted on the supports by clamping bolts 32 whereby the. lower end of the label tube 26 is held in definitely spaced but elastic relation to the periphery of the wheel hereinbefore described and particularly with reference to the extended portions 19 thereof. A runway on the base l consists of an ascending portion 35 and the descending portion 36 whereby a hump-37 is formed at their point of junction. Guiding walls 38 are provided on either side of said runway or chute, so that as a series of articles, such as wrapped pieces of soap as represented by a, 7), c, and d, are passed upwardly upon said chute and past the hump 37 an opening or space 39 is formed within which peripheral teeth 42 on the main wheel will be engaged. A moistening wheel 45 is mounted on uprights 36, the latter being pivoted at 47 on the base l. The said wheel is positioned with reference to the main wheel by means of a bracket 48 against which the upright 46 is normally held b spring 49, adjustment further being given y means of the adjusting screw 50. At the other end of the runway upon the uprights 54 is mounted a wheel 55 which is journaled in the boxes 56 and held in.
normal position by springs 57.
When the machine is to be operated, connection of the hollow shaft 10 is made by a tube 58 with an exhaust fan or pump (not shown) by which the air can be exhausted from the said shaft and itsconnections. A series of wrapped articles such as shown is fed in succession through the chute descri-bed beginning at the left as shown `in Figure 8. As the first article passes the hump 37 it will engage a tooth 42 causing the wheel to revolve. The successive openings of the spokes will register with the shaft opening 2l thereby causing a suction through the spokes, to the holes 20 at the periphery of the wheel. For instance at the first impulse the tubular portion 17a of spoke 17 will register with the opening l 2l. An instant suction will be produced at brought into contact with the upper poi-,
As the wheel tion of the article there positioned as c and aiixed thereto. As the various articles progress they are carried beneath the Wheel 553 which under the stress of springs 57 is brought into pressure contact with the label, thereby positively pressing it into position. As the main wheelv carries the label into its linal attachment position at the lower part, the tubular portion is brought into registration with the longitudinal notch 23 whereby atn'iospheric air rushes in to destroy the vacuum in the tube and free the label.
Registration of the ,tubular structure with each other whereby the timing may be effected is shown in Figure 8 in which a lever 60 is attached to the tubular shaft 10, and a graduated index 61 is attached in the rear thereof so that rotation of the shaft may be given to determine the time at which the desired vacuum may be produced through the hollow spokes when adjacent to the lowermost label in the label holder.
As a further means for providing for variation in the size of the articles passing through the labeling machine, I prefer to provide an elastic section 64 in the run- .way at the point of label application. This is mounted independently of the other sections upon supporting springs 63 which normally hold the section in line with the adjacent sections, but Will yield suliiciently to prevent clogging of the machine when an article of greater than normal thickness passes under the labeling Wheel.
I have illustrated my invention by reference to a practical form and embodiment thereof, but many changes such as the number of the spokes or arms, the number and construction of the several parts and the relative positions thereof to each other may be made without departing from the spiritV of my invention.
