Specification of Letters Patent.

Patented Oct. 15, 1912.

Application filed June 5, 1911. Serial No. 631,307.

To all whom it may concern:

Be it known that I, WVILLIAM I'IALL, a citizen of the United States, and a resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for lVrapping Pamphlets and Similar Articles, of which the following is a specification.

The invention consists in the novel construction, combination and arrangement of various devices, elements and parts, whereby the object of my invention is attained, all as fully and specifically set forth in this specification, and in the accompanying drawings which form a part hereof.

The invention relates more particularly to the type of wrapping machine set forth and described in U. S. Letters Patent No. 699,419, granted to Edward P. Sheldon on May (S, 1902, and consists more especially in certain improvements and modifications of the machine of the said patent, but my said invention is not limited to use with such or any similar machine, but is capable of use with various types of wrapping machines, and it will be obvious that any such use and any modification of the devices herein described which may be necessary to adapt same for use with other machines is within the spirit and scope of my invention.

Before describing in detail the construction and operation of my invention it may be well to state the general plan or mode of operation of a machine of the kind referred to, which is as follows: A single pamphlet, magazine, newspaper or like article to be wrapped, is taken into the machine by devices provided for that purpose, and is conducted to an approximately cylindrical wrapping space formed inside of and bounded by a series of rollers, which rollers progressively bend the article and form it into a cylindrical roll. Before the process of rolling is completed the previously gummcd or pasted wrapper is led into the wrapping space and rolled around the article, which is then ejected from the wrapping space.

In the machine of the above mentioned Sheldon patent the ejection of the rolled and wrapped article is accomplished by allowing the same to drop into a peripheral groove in the lowest series of rollers, (which are of substantially larger diameter than the other rollers bounding and forming the wrapping space) which groove carries the said wrapped and rolled article around and away from the wrapping space and deposits it upon a traveling apron by which it is conducted ont of the machine. Prior to the said Sheldon patent wrapping machines were known in the art whereby articles could be rolled and wrapped in a wrapping space composed of a series of rolls and ejected endwisc from the wrapping space, and also machines in which the rolled and wrapped articles were ejected sidewise between two adjacent rolls which at the proper time were separated for the purpose, and it will be obvious that my present invention is adapted to be used in connection with machines of any of the said types as well as with machines of various other types.

. My present invention relates specifically to the devices for feeding the articles to be rolled and wrapped into the wrapping space, all as hereinafter more particularly described.

In the accompanying drawings, Figure 1 is a side view of a portion of the machine, showing the pamphlet feeding devices and the wrapper feeding, cutting, gumming and perforating devices; the wrapping devices being indicated diagrammatically; Fig. 2 is a side view of a part of a portion of the pamphlet feeding devices, on a larger scale; Fig. 3 is a transverse section, looking back from the front end of the machine, taken on the line 3 3, of Figs. 1 and 2; Figs. 4L, 5 and 5 are detail views showing portions of such mechanism, taken from the other side of the machine from that shown in Figs. 1, 2, &c. and Fig. (3 is a longitudinal vertical section of the pamphlet feeding mechanism, all as hereinafter more particularly described.

Referring now to said drawings, it will be seen that side frames 12 are provided, in which are journaled the various shafts, and by which other portions of the machine are supported. These frames may be of any suitable form and shape. At the front of the machine, being at the right in the side elevations and plan views of the drawings, the pamphlet feeding mechanism is located, and toward the rear the wrapper mechanism.

At the front end of the machine (see Figs. 1 and 2) a platform 13 is suitably supported upon brackets 12, and upon this platform the pamphlets to be wrapped are laid flat, preferably with their backs or bound edges toward the machine. Several of these pamphlets are shown at 14 in Fig. 2. They are placed with their back edges against the upright guides 15, which are secured to the bar 16, which is supported by the brackets 12 and are held in this position by the adjustable stops 17, which bear against the outer or front edges of the pamphlets and keep them pressed backward, their back edges projecting a short distance beyond the back edge of the platform 13, being thus free of its support, and abutting against the segmental reciprocating roller 18 and feeding wheels 19 as hereinafter described.

Upon one of the main driving shafts of the machine, 31, (see Fig. 1) is a bevel gear wheel 32, which engages with another bevel gear wheel 33 on one end of a shaft 34. On the other end of this shaft 34 is another bevel gear wheel 35 which engages with a similar wheel 36 on the shaft 38. On this shaft 38 is a larger plain gear wheel 37, (see also Fig. 2) which engages with the gear 26 (see Fig. This gear 26 is rigidly connected, by the neck 42, (see Fig. 3) to the gear 24, which engages with the gear 25 on the shaft 21 (see Figs. 2 and 3). From the gear 26 extends laterally the interior core or shaft 27 (Fig. which bears the feeding wheels 19 rigidly secured thereto and revoluble therewith, and which also bears the sleeves 18, loose on said shaft 27, and intermediate and also exterior laterally to the wheels 19. From the gear 25 there extends laterally the shaft 21, which also bears feeding wheels 20, located just below and in contact with the feeding wheels 19.

The sleeves 18 are connected together by the bar 22. The sleeves 18 do not revolve, but are reciprocated, by means of the mechanism now to be described, shown in Figs. 5 and 5", and which is located on the side of the machine opposite to that shown in Figs. 1 and 2.

On the shaft 38 is keyed a crank-arm 45, to which is pivot-ally connected one end of a link 46, the other end of which is pivotally connected to a crank-arm 47, which is keyed to the adjacent sleeve 18. It will be obvious that the rotary motion of the shaft 38 thus produced causes a reciprocating rotary motion of the three sleeves 18, which are secured together by the bar 22. The stop 48 prevents too great a movement of the crankarm 47 To the bar 22 and the sleeves 18 are secured blocks 50. The pamphlets lie on the platform 13, pressed by the guides 17 so that they lie fiat when the sleeves 18 are in such a position that the bar 22 and blocks 50 are below the back edge of the lowest pamphlet in the pile. When the sleeves 18 are rotated and the bar 22 and blocks 50 are carried upward, the lowest two or three pamphlets of the pile have their edges pushed backward and thus buckle slightly between the edge of the platform 13 and the sleeves 18. The upward motion of the bar 22 continues until the blocks 50 pass above the edge of the lowest pamphlet, whereupon the pamphlet straightens or flattens out, the edge passing under the blocks. At this time the reciprocating motion of the sleeves 18 and the consequent upward motion of the bar and blocks ceases, and the reverse or downward motion of the bar and blocks commences, and this movement bends the edge of the lowest pamphlet downward so that it passes between the feeding wheels 19 and 20 (Fig. 3) and is drawn into the machine and delivered on to the sloping platform 41, down which it slides to the devices which feed it to the rolling and wrapping mechanism, which feeding devices are shown in Fig. 1 and at the left in Fig. 2.

In order to prevent the whole pile of pamphlets from being elevated or buckled as the bar 22 passes upward, I provide fingers 29, which press upon the edges of the lower two or three of the pile of pamphlets. These fingers are set in the bar 30 and rigidly secured thereto. At the ends of this bar are similar fingers 28, which bear upon cams 51 on the sleeves 18 (see Fig. 4.) These fingers pass through and are supported by the uprights 7 8, and they as well as the fingers 29 also move freely up and down through perforations in the bar 16. They are drawn downward by the springs 52. These parts are shown in Fig. 3, and a portion thereof more plainly and on a larger scale in Fig. 4. It will be understood that the bar 30 is supported in place by the engagement of the fingers 28 and 29 with the uprights 78 and the bar 16.

The devices for feeding along the pamphlets will now be described. On the main driving shaft 31 is secured a small sprocket 60 (shown in dotted lines in Fig. 2.) From this leads a sprocket-chain 61 to a similar sprocket 62 on a shaft 69, which also bears a gear-wheel 63. On the shaft 31 is also a cam 65, which bears against a cam-roller 66 borne on a lever 67, suitably pivoted at 68. The roller 66 is kept in operative contact with the cam 65 by a weight on the lever 67, or a spring operating thereon, or other suitable means. On the other end of the lever 67 is a gear-wheel 64, rigid on a shaft 70. On the shafts 69 and 70 are feedingwheels, 63 and 64 respectively similar to the feeding- wheels 19 and 20. It will be obvious that as the shaft 31 and its cam 65 rotate, the gears 63 and 64 will be intermittently thrown into engagement and will operate the feeding-wheels 63' and 64 on their respective shafts, and that these feeding-wheels will operate to draw the pamphlet from the platform 41 down so that it will be placed in position to be transferred into the rolling and wrapping mechanism. The construction and operation of the rolling and wrapping devices are substantially the same as in the Sheldon patent heretofore referred to and are not claimed in this application and need not here be described, further than to say that the pamphlet is rolled and at the same time a wrapper, which has been previously gummed, is placed around it and secured thereon, and the wrapped pamphlet then ejected from the rolling and wrapping mechanism and delivered out of the machine.

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

1. A. feeding mechanism for wrapping machines, comprising a receptacle adapted to hold the articles to be wrapped, means adapted to separate the edges of the articles to be wrapped at the portion thereof nearest to the wrapping machine so as to permit one of said pamphlets to be gripped, and means adapted to draw said article from said receptacle and deliver same to the wrapping machine, comprising co-acting rollers located near said receptacle adapted to receive said article between them and to deliver same to other co-acting rollers located near the wrapping machine, and means adapted to cause said last named rollers to feed intermittently, comprising a driving shaft of the wrapping machine, a sprocket 62 on one of said rollers, a drive chain 61 engaging with said sprocket and running through said driving shaft of the machine, rocking arms or levers 67 in which the other of said rollers is journaled, gear wheels 63 and G l on said rollers, a cam 65 on a driving shaft of the machine and a cam roller 66 on one of said rocking arms or levers, adapted to alternately throw said gear wheels 63 and 64L into and out of engagement with each other.
