4 Claims. I

My invention relates towrapping machines and more particularly to a type of machine that "will place an outside sheet or wrapper around a quanti-ty of bound pamphlets, magazines, newspapers, or similar articles.

An object of my invention is to provide arlevice that will hold "a stack of sheets or the like, in engagement with one another and in stacked relation to one another while the wrapping operation is progressing.

Another object of my invention is .to provide .a device that will adjust itself to any height of stack, or any number of sheets.

, .Still another object of y invention is to provide a device that is operated .by a single actuatmg means.

When preparing a quantity of newspapers,

magazines or the like .for mailing, it is necessary to wrap varied quantities, depending on the yrequi-red number of copies in each bundle being wrapped. With the device specified, claimed and illustrated herein, it is only necessary .to place the single sheet of wrapping paper .or hinder on the bottom conveyor, together with .the desired .quantity of periodicals and newspapers disposed thereon and they will be conveyed towards the rolls and held in position while they are being put into a compact, tightlyerolled, wrapped package.

The device is simple in construction, easy to operate, and highly efiicien-t for the purpose for which it is intended.

Other and further objects of :my invention becomemore apparent as the description proceeds when taken in conjunction with the drawing in which:

Figure l is .a side elevation :of the assembled device showing the component parts constituting the device.

Figure 2 is a fragmentary view .of the conveyer .arangement, showing a stack of papers on the loading end .of the :bottom conveyor.

Figure .3 is a similar view showing the papers rolled into a compact package and showing another stack in phantom placed on the conveyor ready for wrapping.

Figure 4 is a top viewof the conveyer belt together with the flanged roller at the end pf the bottom conveyer, taken at the line 4-4 in Figure '3, and

Figure 5 is a top view of the top roller on the right in Figure 1.

Similar characters of reference indicate correspond-ing parts throughout the several views, and referring now to the same, the characters It), I'll and W portray ,a frame construction which :may consist .of castings or may be as shown constructed of angle iron or structural steel. v frame has vertical end members II extending upward therefrom, and also vertical plates shown as H and 11 having angularly disposed slots 43 therein. The vertical end members N and the vertical plates I2, are provided'wi-th bearings 154 and I4" near their upper ends which support shafts l5 and 15' respectively, on --which -pulleys 16 are rotatably mounted. These pulleys 46 have grooves on their outer periphery tor the engage- .ment of cables I! and W which support weights 18 .on theirfree ends. 7

'There is a main conveyor unit consisting of a plurality of V-ibe'lts 19 which are horizontally :disposed over =v-pnlleys 2-0 and 241' spaced apart from one another and mminted on shafts 21 and 21 respectively. These shafts are journalledqin bearings 22 and 22" respeetively supported by the vframe member 10'.

There is an idler :roller 28 contacting the lower face of the V- belt's l 9. This idler roller is journal'led on the upper end of pivot-ed levers '24! mounted on a shaft 25 which is tourna-lled in bearings 26 supported on a portion of the frame I'll. IFhe lower depending ends of the levers M are provided with springs H which are attached at 28130 the base of the frame 4H).

There is an auxiliary conveyerunitconsisting or a plurality of V-belts 29-supportedbyt7 -belt pulleys 3:0, 31 and 132 which are mounted on shafts 3%,"34 and 35 respectively and spaced apart from one another. All of these shafts are journalled Withinan auxiliary *frame member shown as 38.

The shafts '34 and 35 engage the slots 1'3 in the verticalplates 1 2 and t2" 'arrdhave the other ends of the cables W and W" respectively attached "thereto. Obviously, the weights *8 are heavy enough t0 almost counterbalance the -weigh-t of the assembled auxiliary conveyor unit'thereby permitting its 'up and down movement w i'thlease, when-guided by the slots P3. The shafts l5 and t5" are equipped with additional "pulleys .37 supporting a cable 38 over a portion of their outer peripheral surfaces. This cable 38 equalizes and controls evenly, the revolving of the pulleys '16 supporting the cables Hand M. s

'The pulleys 30 are of smaller diameter than the pulleys 3-1, thereby creating an angular sec- 'tion 39 on'the bottom ofthe til-belts 29 to permit the engagement of a stack. of periodicals ready to .be wrapped as shown at 4'0 in Figures and 3 between the belts 1'9 and-the belts -29. "The height of the stack 40 will determine the height that-the 3 auxiliary conveyer unit willrise when counterbalanced by the weights [8.

The lower surface of the upper V-belt I9 is supported by a roller 4| mounted on a shaft 42, journalled in bearings 43 supported by the angle irons l9 constituting a portion of the frame I0. A motor 44 acting as an actuator for the pulley 45 mounted on the shaft 46 journalled in bearings 4! shown supported by the frame member revolves the pulley by means of the belt 48. Other bearings 49 are mounted on the frame member ID and support a shaft 50 on which pulleys 5| and bracket links 52 are mounted, the pulleys 51 being rotated by means. of the belt 53 when the pulleys 54 on the shaft 46 are revolved. There are also shown drive belts 55 which revolve the shaft 2| to actuate the conveyer belt l9 on the pulleys 20 and 20".

The links 52 supported by the shaft5n also support a shaft 56 at their upper end, and pulleys 51 are mounted thereon and revolved by means of a belt 58 over the pulleys 5|. Another set of link members 59 supported by the shaft 56 act as a support for pulleys 60 which are .mounted on the shaft Bl which is supported on the frame 3-6 to revolve the top roller 62 in the wrapping operation. The roller 62 consists of a plurality of discs spaced apart from one another and is free to move up and down with the auxiliary conveyer supported within the frame structure 35.

The shaft 46 also supports a frame 53 which acts as a support for the roller 64 journalled on the shaft 65 and revolved by means of the belt 66 over the pulleys 54 and =61 respectively. The frame 53 is supported at 68 by a piston rod 69 forming a part of a piston and cylinder assembly Hi which is provided with a resilient member H. The cylinder in is hingedly attached at 12 and is actuated by a source of pneumatic pressure (not shown) through the tubular member 13.

In operation, the device functions as follows: The magazines or papers to be wrapped are placed on a piece of wrapping paper disposed onto the top surface of the belts l9 and as the belts [9 travel in the direction as indicated by the arrows in Figure 3, the papers will be conveyed towards the angular portion 39 of the auxiliary conveyer, which belts also travel in the same direction, and as the newspapers or magazines are carried between the belts l9 and 29 towards the rollers 62 and 64, they will be caused to assume a cylindrical contour as shown at 14 in Figure 3, and as the wrapping paper forming the outer wrapper for the rolled articles is provided with a strip of glue at its open end, the revolving of the rollers 52 and 64 together with the pulleys 32 on which the belt 29 are disposed will cause the entire unit to assume a cylindrical contour, and when the pneumatic arrangement of the assembly In is put into operation, the piston will be drawn down into the cylinder causing the roller 64 to move downward in its path thereby releasing the rolled periodicals such as the papers or magazines shown at 14.

In the chosen embodiments of my invention, there are many features that are heretofore disclosed in the prior art, and although I have shown a specific arrangement of the component parts constituting the device, I am fully cognizant of the fact that these parts may vary in form and contour and even in arrangement to some extent, without departing from the spirit of my invention or the scope of the appended claims l Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:
