ATTACHMENT FOR CARTON-MAKING MACHINES.

Specification of Letters Patent.

Patented March 27, 1906.

Application filed March 14, 1905. Serial No. 250,010.

To all whom it may concern:

Beit known that l, RICHARD SUNDERMAN, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented a new and lmproved Attachment for Carton-Making Machines, of which the following is a full, clear, and exact description.

My invention relates to carton-making machines and admits of general use, but is of peculiar service in connection with machines of the kind described in mypendingapplication, Serial No. 214,159, filed June 25, 1904.

My present invention embodies several objects, one of which is to slightly open the carton-blank immediately after the same is fed into the machine-that is to say, where carton-blanks are fed into a machine for the purpose of being formed into complete cartons, and especially where they are to be filled- While in the same machine itis desirable that some means be provided for opening the carton-blanks. My invention embraces certain other objects and mechanical details for fulfilling the same, as hereinafter described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.l

Figure 1 is a fragmentary plan view of a carton-machine equlpped with my invention. Fig. 2 is a fragmentary plan view somewhat similar to Fig. 1, but enlar ed and showing certain parts occupying a re atively different position. Fig. 3 is a side elevation otherwise similar to Fig. 1 and drawn upon the same scale as said figure. Fig. 4 is a detail elevation of the plun er. Fig. 5 is a somewhat similar detail of t e plunger, but showing the same as viewed at a right angle to the view shown in Fig. 4. Fig. 6 is a fragmentary elevation of one of the carton-blanks ready to be Fig. 7 is a vertical detail section through the lower end of a cartonblank, the same being opened for the point of the plunger; and Fig. 8 is a sectional view of the sleeve 35.

The general framework of the machine is shown at 8, and at 9 is a chute for feeding the group 10 of carton-blanks into the machine. A slide 11 is disposed obli uely to the general direction of the framewor and is adapted to i convey into the machine the individual carton-blanks 10a, acting substantially as described in my pending application, above referred to. Guide-rai s 13 are separated by a clearance-space 12, into which the cartonblanks are'thus fed. Extending practically across this clearance-space is a standard 14, against which each separate blank 1()a lodges, as indicated in Fig. 1.

The machine is provided with a sprocketchain 15, having movable flights 16, mounted thereupon, the chain engaging a sprocket- Wheel 17, and with a guide 18, connected with the frame-work 8 by means of a brace 18a, as indicated in Fig. 1. A dog 19 is connected rigidly with a rocking shaft 20, the latter being connected by a crank 21 and a cam-rod 22 with a head 23, which slidably engages a bearing 24. .A cam 25 is rigidly connected with a shaft 26, upon which the sprocket-wheel 17 is likewise rigidly mounted. Cranks 27 27 a are rigidly mounted upon opposite ends of the shaft 26 and are pivotally connected by pitmen 28 29 with the slide 11, which has an extension 30. The rotation of the shaft 26 not only causes the slide 11 to'reciprocate, and thus feed the individual blanks 1()al one at a time, as above stated, but after each blank is thus fed in the dog 19 grips the edge of the blank, and thus squeezes the latter edgewise. (See Fig. 2.) For this purpose the cam 25 raises the head 23 in the general direction of its length and causes the crank-arm 21 to rock. The carton-blank being locked against the standard 14 is unable to move any farther in the general direction of its travel obliquely downward, so that the standard 14 serves as a limiting-stop and enables the dog 19 to be effective. Another cam 31 is mounted rigidly upon the shaft 26 and engages an arm 32, so as to lift the same at intervals. This arm is pivoted at 33, carries a spring 33a, and is pnovided with a spring portion 34, which eX- tends obliquely upward, as indicated by dotted lines in Fig. 2.

Centrally disposed at the bottom of the framework is a tube 35, providedy with a slot' 35a, and within this tube is a plunger 36, provided with oppositely-disposed faces 37 of the shape indicated in Figs. 4 and 5.l The plunger 36 is connected, by means of a pivot 38, with an arm 39, the outer end of which is provided with a slot 40, working loosely upon the pivot 38. Another arm 41 is rigidly connected with the arm 39, the two arms virtually constituting a bell-crank lever. The arm 41 is provided at its upper end with a roller 42 and is connected by a spiral spring 43 with a boss 44. The tendency of the IOO IOS

I IO

ist y stems spring 43 is to maintain the arm 41 in an oblique osition, as indicated in Fig. 3, so that the p unger 36 is normally in its lowermost position. A cam 45 is mounted rigidly upon one end of a shaft 46, this shaft being revolubly mounted within a bearing 47 and provided with a bevel-gear 48, -which engages another bevel-gear 49 for the purpose of actuatinor thegluing machinery described in my ro pen ing application.

.-One of the individual carton-blanks aL is shown in Fig. 6 and is provided with a body portion 50, having an indenture 51, the indenture being made by simply cutting out a i5 semicircle of the cardboard materialv of which the carton-blank is made. The blank is split at 52, so that its top and bottom portions are formed into flaps 53 54. When ready for use, Y the carton-blank is in the form indicated in o this figure and may be considered as a rectangular member which has been rendered iiatby a pressure diagonally across it. (See 10?, Fig. 2.)

The arms 39 41 are mounted upon a rockz 5 ing shaft 55, supported by hangers 56, as indicated in Fig. 3. Another rocking shaft 57 is provided with a stud 58, carrying a roller 59. The shaft 57 is provided with an arm 60, extending laterally therefrom, and this arm 3o is connected bya link 61 with another arm 62, t-he latter being rigidly mounted upon a rocking shaft 63. By means of a spiral spring 64 this shaft 63 is normally held in a predetermined position. Extending laterally 3 5 from the shaft is a curved arm 65, which projects into the space 12. This arm 65 is curved slightly, as indicated in Fig. 3. The connection of the pitmen 28 29 with the slide 11 is madeI by means of bosses 28a, as indicated in said figure. Mounted upon the shaft 57 are spring-arms 66, which move upward periodically. The shaft 57 is rocked by means of the stud 58, which is in turn'actuated by means of a cam 26a on the shaft 26.

Spreaders 67 are employed for the purpose of bending the flaps 53 outwardly after the carton-blank is opened, and a surface 68 is so disposed as to bend Vone of the flaps inward, thereby assisting in forming the bottom of 5o the carton.

My invention is used as follows: Power being ap lied to the s rocket-chain and other movab e parts, the s aft 26 rotates in a direction contraclockwise, as seen in Fig. 1. As

5 each carton-blank 10a moves into engagement with the standard 14 and is squeezed edgewise by the dog 19, as above described, the indenture 51 at the lower edge of the carton lodges directly against the lunger 36,

y6o comparatively near the sharp e ge thereof, as indicated in Fig. 7. The spring-arm 32 is at different instances released by thecam 31, as indicated by dotted lines in Fig. 1, and its portion '34 is thus caused to press laterally L6 5 against the lower edge of the carton, so as to lead the same into a favorable posit-ion for allowing the plunger 36 to ascend into the carton-b ank. The revolution of the cani-f4.5 next raises the arm 39 and forces the plunger up into the lower end of the blank, soas-v to spread the same considerably, as indicated in Fig. 2. During the time while the plunger is thus rising the dog 19 continues to press edgewise upon the carton-blank, so that the latter vis widened until it extends completely across the space 12. A moment later, however,the cam 25 having turned slightly so as to release the head 23, the dog 19 is free to swing back out of the way.v The continued revolution of the cam 45 causes the plunger 36 to drop back into its normal position. The revolution of the cam 26al causes the stud 58 to rock outward, thus raising the arm 6() and causing the spring-arm to move abruptly downward. T is movement does not occur until after the carton has been fully opened and started'upon its way, being engaged for this purpose by one of the flights 16. The cartonblank having moved a little to the left of the position indicated by dotted lines in Fig. 3, 9o the upper flaps 53 are spread forward and backward by the downstroke of the springarm 65. Before leaving the position indicated by dotted lines in this figure the springarm 60 makes its stroke upward, however, 95 and bends any one of the flaps 54. Another of these flaps is bent inward by contact with the surface 68, whereas the spreaders 67 cause two upper fla s 53 to bend outward, as abo've y described. do Anot limit myself, however, loo to the particularmeans shown for manipulating the flaps, nor does the'present invention contemplate a complete manufacture and Jiilling of the carton-blank. What I seek more articularly to do at this time is to provide fldr opening the carton-blank by means of the lunger 36, which preferably moves upwardly from the bottom.

Referring to the section shown in Fig. 7 and to the view indicated by dotted lines in Fig. 3, it will be seen that the oppositely-disposed faces 37 of the plunger 36 gradually approach each other at-.the point of the plunger, so as to render the same very sharp. It will also be seen that the spring-arm 34 in pressing laterally against the sharp point of the plunger so that the indenture 51 passes loosely over the point, causes the extreme lower ede of the carton-blank to open slightly before t e plunger begins to rise, so that when the plunger is forced upward the continued opening of the carton is effectedy by a positive motion. The opening of the cartony is instantaneous, being accelerated by the engagement of a fli ht 16 with one of its edges, this flight and t e dog 19 traveling toward each other. By the time the carton-blank 1s opened sufiicientlyto prevent contact between it and the. plunger the latter lsrsuddenly retracted, but the carton now' frictionally engages the rails 13 and is moved along by the flight. The several successive o erations of closing and gluing the flaps and lling the carton form no part of my present invention.
