TIEE-IBUNDLING EIACHINE.

Application filed Apr-i1 13, 1922. Serial No-. 552,331.

To all whom it may concern:

Be it known that I, ALBERT MILLER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and use-V ful Improvements in Tire-Bundling Machines; and I do hereby declare the tollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to machines for pressing together a plurality of superposed tires, tire casings, or like annular objects, and holding them so compressed while they are being bound together by yarns, cords, or other flexible binders, in order that, when pressure is removed, the bundles expand in the binders and may be handled and rolled around without danger of the separate ob jects slipping with respectto each other.

The invention consists in a press having a pair of opposed platens, at least one of which is movable during operation, andmechanical advantage means for effecting relative movement of said platens toward and from each other, each platen being so constructed as to admit of a plurality of binder cords or the like to be passed around the annular objects and snugly secure them while held under compression. I

By means of this improved machine bundles of rubber tires (for example) may be snugly bound together at a plurality of separated points so that the bundles may be rolled around and otherwise handled, each as a unity, without the separate tires becoming displaced or slipping upon one another, resulting in tearing of paper wrappers, chafing, and other mishaps.

In the accompanying drawings in which like reference characters indicatelike parts throughout the several views:

Figure 1 is a side elevation ofa preferred embodiment ofthis invention Figure 2 is a section on the line2 2 of Figure 1 looking down upon the adjustably I fixed platen;

Figure 3 is a section on the line 3- -3 of Figure. 1 looking down 'uponthe plunger platen. 1 V

In the embodiment illustrated, 1 indicates thebase of apress' frame adapted to rest upon a floor'or other foundation and to be secured thereto. At diametrically opposite points on said base 1 are bosses 2, in which are threaded; openings tor the reception of hollow columns 3 screwed thereinto and ex tending upwardfrom the base'l in parallel relation. The upper ends of columns 3 are tied together and braced by a cross tie 4 which may be secured to the upper ends of the columns in any suitable manner as by being fitted over the upper ends and secured in place by set screws 5. brace t may be divided, or have openings therein, to receive sheaves 6 and the upper ends or the columns may be slotted to accommodatesaid sheaves. A chain 7, or other flexible membenis passed over each sheave, one end of each chain being attached .tov a. counterweight 8 within a column '3 and the other to an adjustable platen that is adapted tc be fixed at any desired level vto the columns 3. i p r In this embodiment the saidfixed platen comp-rises a plurality oi arms .10 and 10 preferably tour, suitably strengthened and reintorcedby the ribs 9. The ends of the two arms 10 may be expanded to form split circular clamps 11, or the said clamps may, if desired, be secured to said arms. Each clamp is provided with'laterally extending lugs 12 and 12 having alined openings drilled therein, the opening in the lug 12 being slightly smaller than the opening in the lug l2 land threaded, as shown. A clamp bolt 13 passed through the opening in lug 12 is threaded into lug 12. By ,means of the clamp bolts clamps 11 maybe tightened upon the columns 3 or released therefrom. In order to turn the bolts 13, handles 14; are pivoted to the bolt heads; and it will be obvious that the ends of said handles ad-. jacent the clamp may serve as cams whereby quick setting action of the clamps may be secured. 'Se'curedito the underside of the platen arms 10, 'lO is a plate let having equally spaced .peripheral openings or notches 15 for the purpose of enabling a binder-cord to be readily passed around the tires, tire casings, or other annular The, cross tie or dle of "superposed tire casings or the like are larly strengthened by ribs 16-. The ends of the arms in the movable platen need not, however, embrace the columns 3 but are preferablyvprovided with yokes or curved guides 17 fitting the inner races of the col umns 3 so that the said platen in its up and down movements may be guided byfsaid columns. At the center of the movable platen there is a h0le 24 which is adapted to receive the upper end of a piston rod 24 to be presently described. Upon the upper face of thepluifger platen a supporting plate 18 rests and be bolted 'or otherwise secured to the arms 15 and 15 if desired. The supporting plate 18 is provided with peripheral Irotches 19' corresponding in position and preferably also in shape with the notches 15 of the described plate l l'so that when a bunheld between the plunger platen and the fiked platen an operator may readily pass binding cord around the several tires or other annular 'obj'ectsthrough said notches or operri ngs and securely; tie them together.

Mounted on the central portion of the base 1 is a cylinder 20 having flanged upper and lower fend's', the lower flange being perforated for thefre'ception of cap screws 21 which are threaded into the base 1 in "order to secure said cylinder in place, and the upa ntings having threaded hol'esfor the reception of cap screws '22 which secure the 7 cylinder head 23 on the cylinder. Said cylinder head 23 has a central opening for thepassage of the piston rod 24 attached to the piston 25, the upper end of the rod 24; being reduced as at 26,"said reduced end entering V r the opening 24 at the center of the plunger platen, tries-hanger at the junction of the reduced portionee with the main portion of i the piston "rod 2l'supporting said plunger platen. Adjustably secured to the cylinder head '23 is a stufiing box 27 ofan'y approved type adapted to pack'thepiston rod. Tapped into the lowerendfof the cylinder 20, is a main 28 for''c'ondiuiting air or other suitable .fluid into the cylinderQO for forcing the piston 25 upward a'nd thereby lifting the plunger platen.- T he in'let of fluid to the cylinder 20*maylbe'controlled by a three way 5 valve 29 which whenin"one'position"admits fi uid to thecylinderQO and While in another position opensc'ylinder 20 to the atmosphere inorder re exhaust the flu-id therefrom and permit the descent of the plungerplaten.

quickly adjusted and released.

Although the utilities of my invention may be realized to anextent by arranging the'pl'u nger platen and an operating means above the adjustably fixed platen, yet 1 prefer the arrangement shown because of the greater convenience in using the apparatus. By means of the construction shown the plunger platen may be lowered'toa height making it convenient for workmen to lift heavy objects ontoiit preparatory to compressing them.

In operation, tlres suitably wrapped in paper, or other annular objects, may be superposed on theiplunger platen, For example, a set of five tires may 'be placed one upon the other in a pile on top or, the plate 18 of the plunger platen and centered thereon 'by'hand When so placed sufiicien't space is provided" at the i inner "portions of the notches 15. and 19 (which are of'grea'ter radial "extent than the thickness of the objects) for the ready passage at rope yarn, cord or other binding material-between the inner surface of the bundle and the plate. Also the plates '18 and 14' present 'sufiicient-sustaining surface to the tiresso that theycannot bulge materially into thenotches l5-=and 19 under the pressure-exerted. s

According tothe size of-thetire's or other objects and the number toq-be bundled in a single :bundle the fixed platen andthe gage stops 30 should beadjusted axproper distance apart in orderthat the necessary amount of pressure, and no more, shall have been exerted upon the bundle when the plunger platen'engages the stops. ;A=f ter the plunger platen has been raised into engagement with the stopsgtheftires notherQannular objects will beheld clampedrand squeezed 7 together under moderate pressure suchthat,

the superposed "objects 1 have been I have found by experlment tha -t the best 7 results compatible, with jeconomy or labor and bindingcord is secured by tyin'g the bundle of tires or other annular objects in four places substantially equally spaced. Less than four ties about a plurality of tires makes an insecure bundle and more than four is wasteful. I have therefore shown each plate 14: and 18 provided with four notches symmetrically spaced about the edges of the plates.

The adjustable platen 9 is counterweighted so that it may be readily adjusted to position without excessive labor. v

Cord for tying the compressed bundles may be carried on spools arranged on a reel above the apparatus in such position that the ends may depend within convenient reach of the workmen; or the workmen may be supplied with yarns, or binder cord, cut to proper length for surrounding the bundle and affording ends for tying. The manner of supplying the cord is no part of the present invention and is not illustrated.

Having described my invention what I claim and desire to secure by Letters Patent is:

1. In a machine for bundling tires or the like, a frame, a platen adapted to be adjustably fixed thereto, a plunger platen guided thereby, fluid operated means for moving the plunger platen toward the fixed platen, and separate means for adjustably limiting the extent of movement of said plunger platform toward the adjustably fixed platform.

2. In a machine for bundling tires or the like, a frame, a platen adapted to be fixed to said frame, a plunger platen movable toward and from said fixed platen, mechanism for moving said plunger platen toward the fixed platen, and adjustable stop means carried on the frame for limiting the movement of said plunger platen toward the fixed platen.

3. In a machine for bundling tires or the like, a frame comprising parallel uprightcolumns, a platen adapted to be fixed to said columns, a plunger platen guided by said columns, means for moving it toward said fixed platen, and stops on said columns adapted to be secured at different distances from the fixed platen in order to limit the movement of the plunger platen toward said fixed platen.

4. In a machine for bundling tires or the like, a frame comprising upright parallel columns, a platen adapted to be fixed adjustably at various elevations along said columns, a plunger platen guided by said columns beneath said fixed platen, fluid pressure mechanism adapted to lower or raise said plunger platen, and separate means for adjustably limiting the extent of upward movement of said plunger platen.

5. In a machine for bundling tires or the like, a frame, opposed platens mounted on the frame, means whereby one of said platens may be fixed at different distances from the other, counterbalancing means for the adjustable, fixed platen, means for forcing the other platen toward the adjustable, fixed platen and separate means on the frame for limiting the movement of said other platen.

In testimony whereof I affix my signature- ALBERT MILLER.
