Application filed August 15, 1896. Serial No. 602,878. (No model.)

To, ctZZ whom it may concern:

Be it known that I, ROBERT A. CARTER, a subject of the Queen of Great Britain, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Wrapping, Folding, and Sealing Circulars, of which the following is a specification, reference being had to the accompanyto ing drawings, forminga part thereof, in which similar letters and numerals of reference indicate corresponding parts Wherever found throughout the several views.

This invention relates to machines for folding and w'rapping'pamphlets, magazines, circulars, bills, and other documents; and the object thereof is to provide an improved machine of this class which is simple in construction and operation and which is designed to fold and wrap the articles referred to and to seal said wrappers.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in Whl0ll- Figure 1 is an end view'of my improved machine; Fig. 2, a side view thereof with part of the construction in section; Fig. 3, a section of a detail of the construction; Fig. 4, a plan view of a part of the construction shown 0 in Fig. 3; Fig. 5, a partial section on the line 5 5 of Fig. 2, showing the circulars to be folded and the wrappers by which they are covered in position; and Fig. 6, a sectional side View similar to Fig. 2, but showing the 5 parts in a different position.

In the practice of my invention 1 provide a suitable main frame, in which is mounted a longitudinal power-shaft (5, which is provided with a balance-wheel 7 and a yoke-crank 8,

with which is pivotally connected a rod 9, which is also pivotally connected with a pedal 10. Said power-shaft may be turned or operated by said pedal, or any suitable means may be employed for accomplishing 5 this result, such as a crank-wheel at one end of said shaft; or a power pulley may be mounted thereon, and said shaft may thus be turned by steam or electric power. I also provide a supplemental shaft 11, which is mounted in the frame parallel with the powershaft 6 and at a suitable distance therefrom.

-Mounted on said supplemental shaft and about centrally thereof is a drive wheel 12, provided with a wide rim 13 and radial spokes 14, and secured to one side of the rim 13 is a segmental or circular gear-plate 15, which is provided with gear-teeth 16 on its outer perimeter. Secured within the rim 13 is a segmental or circular flange-plate 17, said plate being also secured within the segmental or circular gear-plate 15 and terminating at one end thereof, as shown at 18, and projecting slightly beyond the opposite end, as shown at 19.

The end 19 of the segmental or circular flange-plate 17 is curved outwardly toward the rim 13 of the drive-wheel, and said flange-plate is bolted to the spokes 14: of the drive-wheel, as shown at 20 in Fig. 2;

Mounted on the power-shaft 6 is a pulley 21, and a powerbelt 22 is mounted on the rim 13 of the drive-wheel and on said pulley 21. Below the drive-wheel or the lower end of the circular or segmental gear-plate 15, as shown in Figs. 1 and 2, is a gear-wheel 22,

which is adapted to operate in connection with said gear-plate 15. Said wheel 22 is mounted on a shaft 23, the outer end of which passes through the frame and is provided with a beveled gear-wheel 24, and the free end of which is supported by a cylindrical head 25, formed on a bracket or arm 26. The cylindrical head 25 is provided with an upwardly-directed arm 27, on the inner side of which is a keeper 28, through which passes a vertically-movable bar 29, which carries at its upper end a roller 30, and the lower end of which is adaptedto enter a notch or recess formed in the hub 31 of the gear-wheel 22, as shown at 32. Said bolt 29 is adapted to be operated by the circular or segmental fiangeplate 17, as hereinafter described.

The upper part of the main frame is provided with a transverse rod or bar 33,0n which is formed a sliding sleeve 34, which is provided with a depending plate or arm 35, the 5 lower end of which is provided with a vertical slot 36. The plate 35 is provided on its outer side with a keeper 37, between Which and said plate is mounted a vertically-movable slide 38, which is provided with an arm I00 39, which extends through the slot 36 and is provided at its inner end with a roller 40.

The plate 35 is also provided on its outer side with an arm 41, to which is pivoted at 42 a crank-lever 43, one end of which extends inwardly and is adapted to entera slot or opening 44 in the upper end of the slide 38, and the other arm of which extends upwardly and is provided with a pivoted head 45, with which is connected a rod 46, the function of which will be hereinafter explained.

The plate 35, which is secured to or formed on the sleeve 34-, carries a revoluble head 47, which is provided on the inner side of said plate and adjacent thereto with a locking-disk L8, and the upper end of the slide 38 is provided with an arm 4.), which projects through the slot 36 in said plate and is curved upwardly and adapted to operate in connection with said lockingdisk 48. The head 47 is also provided inside of the locking-disk 48 with a circular gear 50, which is operated by the circular or segmental gear-plate 15, these features of construction being best shown in Figs. 2 and 3.

Mounted on the shaft is a stationary sleeve 51, which carries a tubular sleeve 52, and secured to the inner side of the head 47 or the side of the circular gear 50, or formed thereon, is a tube 53, which passes through the sleeve 52 and in the upper side of which is formed a longitudinal slot or opening 54, one side of which is provided with an inwardly-directed longitudinal plate 55, at the lower edge of which is an angular longitudinal plate 56, which forms a bottom for the longitudinal opening or slot 5-1. Mounted in said tube 53 is a sliding and turning gate 57, which extends almost the full length of the tube 53, and formed in said gate 57 are inclined and curved slots 58, through which project pins 59, formed on or secured to the inner side of the tube 55. Said gate 57 is pro vided with two in wardly-directed lugs or projections (30, through which the rod 46, which is connected with the head 45 of the upper arm of the lever 43, passes, said rod being passed centrally through the head 47,as shown in Fig. 3, and through said in wardly-directed lugs or projections 60, as above described. Said rod 46 is provided centrally thereof with one or more nuts or burs 61, between which and the inner lug or projection (30 is a spiral spring 2, and a similar nut or bur (33 is also secured to said rod in outside of said inner lug or projection (30, and between the nut or bur (i3 and the outer lug or projection (30 is another spiral spring 64-. Secured to said rod &6, between the inner lug or projection 60 and the nut or bur U3, is another nut or bur 65, which is provided with an arm (36, with which is connected a s1 rong spiral spring 67, one end of which is secured to the head 47, within the tube 53, and the funcl ion of which is to throw the rod 46 outwardly and to hold it in c011- nection with the head 415.

The beveled gear-wheel Bl on the end of the shaft operates in connection with a corresponding beveled gear-wheel 68, as shown in Fig. 2, said gear-wheel (58 being mounted on a vertical shaft 69, the upper end of which is provided with a crank 70, which is pivotally connected with a rod 71, which is pivotally connected with a shoulder or projection on the lower side of the sleeve 3i, as shown at 72 in Fig. 2. By means of this arrangement the sleeve Si is caused to slide on the rod 33 in the operation of the machine, as hereinafter described.

Secured transversely of the machine and immediately over the tube 50 are two downwardly-

inclined chutes

73 and 74, which are separated centrally bya triangular partition composed of

upright walls

75 and 76, said partition-walls being connected at their lower ends. In the bottom of the chute 73 is a slot or opening 77, and a similar slot or opening 78 is formed on the opposite side. Mounted transversely of the partition wall or plate 7 6 is a roller 7.), and a similar roller is mounted transversely of the partition wall or plate 75. In practice the covers for the pamphlets, circulars, and other articles to be folded, wrapped, or covered are placed in the chutes 73, against the partition plate or wall 75, as shown at B, and the circulars or documents are placed in the chutes 74-, against the part-ition wall or plate 76, as shown at I). Said wrappers or covers and said circulars or documents are held in place by triangular blocks 81., which are placed in said chutes, as shown in dotted lines in Fig. 1 and in full lines in Fig. 5, the detailed construction of this part of the apparatus being best shown in, Fig. 5. The object of the triangular. blocks 81, which are adapted to slide inwardly and downwardly, is to hold said pamphlets, circulars, or other documents and said wrappers or covers in position against the partition plates or walls 75 and 7G.

The shaft 82, on which the roller 79 is mounted, is provided with a gear-wheel 83, and the shaft 84, on which the roller 80 is mounted, is provided with a corresponding gear-wheel 85, these gear-wheels beinglocated at the outside of the chutes, as shown in Figs. 1 and (3. Above the gear-wheel 83 is a ratehetwheel 8 which is adapted to be operated by a sliding rack-bar 87, one end of which is pivotally connected with the upper end of a lever 88, as shown at 89, by means of a slot formed in said lever. The lower end of the lever 88 is connected with a shaft 90, which extends parallel with the shaft or rod 33, and the inner end of which is provided with a crank 91, which is operated by a pin or projection 92, formed on the circular or segmental gcar-plate 15, and on the shaft of the ratchet-wheel 86 is a small gear-wheel 86, by which the gear-wheel 83 is operated. By means of this construction the circulars, pamphlets, and other documents and the wrappers therefor are fed through the openings or slots 77 and 78, as hereinafterdescribed, into the longitudinal slot 54 in the tube I also provide means for gumming the wrapposition by the sliding blocks 81.

pers and for sealing the same, which consists of a suitable vessel 93, which is supported at one side of the tube 53, and at the lower edge thereof, adjacent to the tube 53, is a shaft 94, provided at each end with arms or cranks.

95, which support a roller 96. The shaft 94 is provided at its outer end with a curved crank 97 which is adapted to be operated by a similar curved or segmental crank 98, secured to the end of the shaft 11, on which the drive-wheel 12 is mounted. One of the upwardly-directed arms 95, between which the roller 96 is mounted, is provided with a spring 99, one end of which is secured to the support of the vessel 93, and said spring is adapted to hold the roller 96 in contact with a roller a, which is mounted on a shaft supported at the top of the vessel 93, as shown at a in Fig. 1. The shaft on which the roller a is mounted is provided with a pulley at its inner end, which is not shown, and the main power-shaft 6 is provided with a similar pulley a and a belt a connects said pulleys. I also provide a roller a which is supported by pivoted arms a and which is adapted to bear on the side of the tube 53 opposite to the roller 96, and a spring or springs a", secured to said arm or arms, hold the roller a in contact with the tube 53.

The operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawing, and the following statement thereof.

The normal position of the parts is that shown in the drawings, and in practice the circulars or other documents to be wrapped and sealed are placed in the chute 74 and press against the wall or plate 76, and the wrappers are placed in the chute 73 and press against the wall or plate 75, and said documents'and said wrappers are secured in this The powershaft 6 is then revolved by the pedal 10, or by any suitable means, and this operation revolves the drive-wheel 12, and the pin or projection 92 on the segmental gear-plate 15 strikes the lower end of the crank 91. Said crank operates the shaft 90, which in turn operates the crank 88, by which the rack-bar 87 is operated, and said rack-bar, through the ratchet-wheel 86, operates the gear-

wheels

83 and 85, which operate the rollers 79 and 80. At this operation one of the circulars is fed through the slot 78 and one of the wrappers through the slot 77, and both are passed into theslot 54 in the upper side of the tube 53 and at the same time. The outwardlyinclined end 19 of the segmental flange-plate 17 strikes the side of the roller 40, which is connected with the slide 38, and forces said slide downwardly, releasing the arm 49 from the locking-disk 48, and drawing down the lower arm of the lever 43 forces the rod 46 inwardly. This operation of the rod 46 forces the gate 57 outwardly and at the same time turns it so as to force the upper edge thereof against the lower edge of the circular thereby in the direction of the arrow, as shown in Fig. 5. 53 and wraps the circular thereon, also the wrapper, the wrapper being on the outside of the circular, and said wrapper and said circular are held in contact with the side of the tube 53 by the roller (i At the proper time the roller 96 is thrown forward by the crank 98 on the shaft 11 striking the crank 97 on the shaft 94, and said roller 96 presses upon the wrapper as the tube 53 revolves and applies the gum thereto. Said roller 96 is again retracted by the spring 99 after it has been operated as described, and as the tube 53 continues to revolve the roller a presses the end of the wrapper over the gummed portion thereof and seals it thereto. As the wheel12 continues to revolve the roller 40 is released or passes over the opposite end of the segmental flange-plate 17 and the end 19 of said flange-plate passes beneath the roller 30 and raises the arm 29, to which it is secured. This releases the gear-wheel 22, and as the wheel 12 revolves the gear-plate 15 engages with the wheel 22 and revolves the shaft 23, which operates the vertical shaft 69, which operates the crank 70. This operation draws outwardly the sleeve 34 of the plate 35 and with it the tube 53, which slides in the sleeve 52, this position of these parts being shown in Fig; 6, and the sealed circular is removed from said tube by said sleeve 52 and drops onto the floor or into a receptacle prepared therefor. As said wheel 13 continues to revolve, the sleeve 34, the plate 35, and the tube 53 will be returned to the position shown in Fig. 2, and this operation continues as long as the power-shaft 6 is operated.

It will be understood that the vessel 93 is provided with any suitable gumming material, such as mucilage or glue, and the roller a is constantly turning therein. The roller 96 is in contact with said roller a except when operated by the

arms

98 and 97, as hereinbefore described.

I have also shown in Fig. 5 a spring-operated pin or blade a which passes outwardly through the partition plate or wall7 5 in the chute 73, and the object of this device is to prevent all the wrappers except the one in contact with said plate or wall from being drawn or forced downwardly through the slot 77 by the roller 80, and this pin or blade passes through or into a number of said wrappers, and the one adjacent to said plate or wall is torn off by said roller and passed downwardly through said slot, as hereinbefore described, while all the rest areheld in proper position to be operated upon by the said roller. 1 also provide the roller 79 with a number of small teeth or sharp points which pass into the circular or document to be forced through This operation revolves said tube v the slot 78, and the operation of this roller is thus made positive at all times. The roller 80, by which the wrappers are fed through the slot 7 7 is preferably provided with a sanded or otherwise-roughened surface. The head 45, which is connected with the lever 4L3, is pivotally secured thereto and the outer end of the rod ad, which is pivotally connected with said head, is pointed and passed into a socket formed therein. The spring 67 serves to press said rod into said socket, and the springs 62 and (3 1 serve to give the gate 57 a yielding pressure against the paper or the circulars and wrappers, so as to accommodate the action of the gate to the thickness of said paper or of the circulars and wrappers.

The segmental gear 15 is so proportioned to gear 22 that the latter will have one revolution for each operation of the machine, while the gear 50 is so proportioned to the gear 15 that it will revolve three times for each operation of the machine.

Myimproved machine is simplein construction and operation and perfectly adapted to accomplish the result for which it is intended, and it is evident that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages, and I reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

The slotted, revoluble, and longitudinallymovable tube 53 constitutes the core on which the documents and wrappers are wound, as herein described, and it will be apparent that this core may be made of any desired size or diameter, and the construction of the parts connected therewith may be regulated so as to adapt the device to circulars, periodicals, and various other printed publications of different shapes, sizes, and thicknesses.
