WATSON H. CLINE, OF CAMDEN, NET JERSEY, ASSIGNOR OF ONE-HALF TO JAMES E. IIAYS, OF SAME PLACE.

PAPER-EAG MACHINE.

SPECIFICATION forming part of Letters Patent` No. 458,559, dated September 1, 1891.

Application filed September 17, 1890. Serial No. 365,288. (No model.)

To all whom, it #may concern.-

Be it known that I, IVATSON I-I. CLINE, of the city and county of Camden, and State of New Jersey, have invented an Improvement 5 in Paper-Bag Machines, of which the following is a specification.

My invention has reference to paper-bag machines; and it consists of certain improvements which are fully set forth in the followro ing specilication, and shown in the accompanying drawings, which form a part thereof.

My improvements have particular reference to apparatus for manufacturing satchelbottoms upon bellows side-fold tubes, whereby the formation of the bag may be had in a continuous manner and while the bag-tube is in motion passing through the machine.

In carrying out myinvention I employsuction for the purpose of opening the tube for 2o permitting the entrance of the bottom-forming mechanism. The tube after leaving the tube-formingmechanism is received between the two endless aprons or bands, from which one end of the tube projects. rlhe tube is conveyed between suction-boxes, through which air-currents are formed and by which the sides of the paper tube are drawn apart, forming an entrance at one end of the tube. As soon as the tube is opened in this 1nan- 3o ner 'fingers are projected into the interior thereof and then caused to move away from each other until they reach points corresponding to the four corners of the bottom. IVhile in the custody of these fingers a pair of 3 5 hinged plates or blades are thrust down into the mouth of the tube and by suitable devices caused to lie flat upon it to positively fold the free edges of the paper tube into a condition for subsequent proper folding and 4o pasting of the bottom. Immediately after creasing the paper into the proper shape for the bottom these plates and the fingers are removed automatically, and then by pasting, creasing, and folding` devices the Satchel-bottom is completed upon the bellows side-fold tube.

In the operation of my improvements the aforesaid fingers and plates are connected to a series of carriages, which are caused to 5o travel with a speed equal to that of thev conveying-bands, by which the tubes are held and caused to travel through the machine. While the said carriages and their operatingingers and blades or plates are being con@ veyed in contact with the tubes the said parts are automatically manipulated by suitable cam devices, which cause them to perform their operations at predetermined moments and with proper relation one with respect to the other. 6o

In the drawings, Figure l is a front elevation of my improved machine with the de' vice for shaping the bottom removed. Fig. 2 is a plan view of same, showing the driving mechanism for the device for forming the bottom. Fig. 3 is a perspective view of one of the suctionboxes for opening the tube. Fig. 4 is a front elevation of my improved machine with each end cut away and a portion of the bottom-forming mechanism re- 7o moved. Fig. 5 is a plan view of same, showing the bottom-forming mechanism in position. Fig. (5 is a plan view of the cams for operating the forming blades or plates. Fig. 7 is an elevation of same. Fig. S is a front 75 elevation of one of the carriages for carrying the forming plates and iingers. Fig. 9 is` an end view of same with part in section. Fig. l() is an elevation of the forming plate 0r blades and operating mechanism therefor, 8o with part in section. Fig. Il is an end view of same, also with part in section; and Fig. 12 `illustrates a series of tubes in the process of form-ation, and shows the several operations in the formation of the bottom.

A A are two endless bands passing about the pulleys B, arranged at each end of the machine. These pulleys may be driven in any suitable manner, so that the two endless bands are caused to travel in contact for a 9o portion ot' their length.

C is the frame of the machine arranged between the bands and wheels B. To thisframc C are secured the 4two boxes D, arranged adjacent to the feeding ends of the bands and formed substantially as illustrated in Fig. 3 that is to say, having the opposing faces made with perforationsD. These boxes connect with an exhaust-pipe d, leading to an exhausier D2. By the operation of the eX- Toe hauster air is drawn through the apertures D, causing the faces of the bellows side-fold tube to be drawn apart upon passing between the said boxes D.

E represents mechanism for forming the bottom of the bag prior to its being folded down and pasted, and this mechanism is arranged in front of the boxes D andthe frame C, adjacent to the boxes.

F are two endless bands which travel upon each side of the feeding-bands A and are guided over rollers f. These bands are caused to travel bymeans of suitable gearing, or ot-herwise, so as to move with a speed equal to that of the feeding-bands A. The object of these bands F is to receive the folded paper forming the bottom and convey it along with the tube, which is in the custody of the bands A, and at the same speed so handle it that the paper shall not be dragged out of shape. The bottom of the bag is folded into the shape shown at 5 in Fig. 12 bythe time it reaches the plate Q, andthe tube is then conveyed by the bands Aunder the plate Q and receive paste from the paste-applying rollers C. As it continues its travel it passes under the creasing-disks C2, which crease the bottom on the lines on which itis to fold. After being creased it passes under a roller C4, which is kgiven a vertical and lateral motion by means of a frame C5, holding the roller and connected to rotary cranks C, said cranks being rotated by means of gearing c. The gearing c is made eccentric, so that the movement of the roller C4 is notl uniform as to velocity, but is greatest while acting upon the paper tube and slowest in returning to be in a position to act upon the next tube. The motion of this roller C4 is designed to push over the creased flap, and then roll it down, at the same time traveling with the moving bag-tube. A similar roller and mechanism is arranged immediately after the ,first-mentioned roller, and is designed to roll down the opposite pasted flap. The action of these two rollers upon the bag is illustrated in Nos. 7 and 8 of Fig. 12. No. 6 illustrates the creased paper tube before reaching the rollers C4, and after being actuated upon by the creasingdisks G2. After the bottom is formed, as in No. 8 of Fig. l2,it passes under the pressureroller C3, and is then completed.

The mechanism E for forming the bottom of the bag ,is clearly shown in Sheets 2 and 3. It consists of a series of carriages G, arranged end to end and guided in suitable-guides E3, Figs. 4 and 8. EachV of the carriages G is preferably formed of three parts hinged together, as is clearly shown in Figs. 5 and 8, for the purpose of more readily turning' the curves. The carriages are held at a given distance apart by means of screws g', attached to the carriages, and the heads of which are caused to rest against the next succeeding carriage. Each of the carriages is provided with a pin or projection G2, which is acted upon by the teeth of the propelling-wheels O, which propelling-wheels are secured upon shafts e, geared together by sprocket-wheels E and chain E2. These shafts e are driven by gearing B from the main shaft b of the pulleys or wheels B, (see Figs. 1 and 2,) whereby the speed of the carriages G is in exact accordance with the speed of the bands A and F. The guide-rails E3 are grooved and receive guide-rollers g, which are secured tothe carriages, as shown in Fig. 8. In the central portion of the carriage there is a sliding frame L, projecting' toward the bands A, and to the free end of this frame L and pivoted at m are two forming .blades or plates'M, Figs. lO and ll. These forming-plates are rotated upon their bearings by means of a reciproeating shaft L', which is guided within the frame L and is normally acted upon by a spring L2, carried in the frame L, for the purpose of bringing the two blades M parallel,

as shown in Fig. ll, in which position they l are ready for entrance into the opened bagtube. The rear end of the frame L is provided with a wheel Z, which works in a camway N, and likewise the rear end of the shaft L is provided with a wheel Z', which works in a grooved camway N. These camways are shown in Figs. 5, 6, and 7 and are designed to move the blades toward the bands A until within the open tube, and then while holding' the frame L operate the shaft L to cause the said blades M to rotate about their bearings m and open out flat into the position indicated at 4, Fig. l2.

Upon the end pieces of the carriages G are journaled the reciprocatingand rotating rods G', carrying at their free ends the cranks H, which are formed with long fingers adapted to enter the bottom of the tube when opened by the suction-boxes and by proper manipulation bring the tube to the shape shown at 2 in Fig. l2, and while so held permit the blades M to be forced into the open end of the tube, as indicated by numbers 3 and 4 of Fig. l2. The rotary reciprocating shafts G pass through pinions J, carried upon the carriages, (see Figs. 8 and 9,) and these pinions J are rotated in opposite directions, so that the two adjacent shafts G', or those upon one end of the carriage, are rotated in opposite directions. The pinionsJ at one end ot' the carriage are connected on adjacent sides to a rack I by suitable teeth, and this rack is made jointed and is provided with teeth at the other end operating upon the outer or opposite sides ot' the corresponding pinions J ot' the other two reciprocating and rotating shafts G. It will thus be seen that each of the carriagesv G is provided with four shafts G and four cranks H. The rack I is reciprocated upon the carriage G by means of the lever-arm K, pivoted at one end to the middlcportion of the carriage G and provided at the other end with a roller k, which works upon a cam R, secured to the frame C of the IOO IIO

machine, and on the side adjacent to the bands A, Fig. 4. As the carriages travel adjacent to the bands A, the cam R causes the lever-arm K to move against the action of a spring K and induces a reciprocation of the rack I. This action causes the cranks H to move farther apart, and thereby open the end of the bag-tube into the shape shown at 2 in Fig. l2. Asit is necessary for the cranks H to enter the tube, provision is made for their longitudinal reciprocation through the pinions J and J which provision consists of a camway P, Fig. 5, which acts upon the shafts G" to thrust them forward to project the cranks H into the open tube while in the custody of the suction-boxes D. After being projected into the open end of the tube the said shafts are held against reciprocation while they are rotated in the manner above specified to cause the bag-tube to be opened into a condition to receive the forming-plates M. After the bag has been shaped in th-e manner above described the curved ends of the camways N and N causes the plate INI to be Withdrawn'from the tube, and the rear oblique end of the camway P causes the cranks or fingers H to be withdrawn from the tube, and these parts pass around with the carriages into a position to act upon successive tubes. The cranks and crank-fingers H, during the entrance of the forming-plates M, are moved and are received through curved slots m', Fig. l0, into blades M, and while the blades M are entering into a nal position within the tube the crank-fingers are withdrawn. Subsequently the blades M are withdrawn and the tube folded in the condition at 5 in Fig. 12 passes on to the pasting-rolls, and then to the creasing and folding mechanism. The various rotating and moving parts are mechanically connected together or with proper power machinery of any suitable construction, whereby their movements and speeds have a given relation with the surface speed of all the parts, and so far as their movement in the direction of the travel of the tube is concerned said movements are equal to the speed of travel of the bands A.

It is quite evident that the details of construction might be more or less modified without in the least departing from the principles of my invention. Hence I do not limit myself to the details herein set out.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
