PQWER BALHVG PRESS.

Application filed January it, 1925. Serial No. 1,565.

My invention hes reference to power baling presses, and is specially designed for use in large stores and factories, where there is a considerable accumulation of waste paper and similar refuse matter, lit is of that clam in which it is intended to have the materiel ted in at the top, end one of the 2 features thereof consists in simple and novel mechanism for tipping the platen to one side, out of the way, at the upper end of its movement.

The device includes s. receptacle for the waste material, having hinge-d side plates, which, with angular end extensions, comprise three sides of the receptacle, and which, when open, permit the contents of the mo.-

chine to he approached and removed from either side, as desired.

The machine is shown and described herein as heing arranged for and driven by electricnl means, but the 5 me can be readily adopted for operation y other lrinds of power, The use of electric power insures a quick response to the requirements of the operating mechanism, and renders the same more easily handled. This includes devices for automatically arresting the movement oi the platen dowardly, in the compressing operation, when the pressure attains a predetermined intensity. Limit switches are also installed in connection with the electrical system, to automatically checlr the movement of the platen at a point in its upward movement, and at another point in its downward movement. 17*

The above-named, and other features and advantages of the invention will more fully ap cur from the following specification, re erence being had to the accompanying drawings, in which:

Fig. 6 is a plan view of the superstructure.

Z is an end view of the superstructure, with port of the frame cut away.

formed of a pair of I-beams 1, united by cross-plates 2, provided. at their edges with ribs 3, united at a central point by cross-ribs l2. Between the plates 2 is fined a floor 5. provided at regular intervals with channels 8, for the passage of wires in binding the completed hole of paper. Near the ends of the base are supported corner-

posts

7 and 8, united at front and back by channel-pistes 9. Each pair of said posts is also united at their upper ends by cross-plates 10, and fun ther braced by cross-ties ll. (Ti 5;)

The receptacle for the material is termed ot a pair of spaced-apart end-plates 12. to the outer edges of which are hinged side plates 13. bent at their free ends into endplates 14, parallel with the plates 12, and similarly spaced. The edges of the endplates it are reinforced by angle-plates 15. and the inner edges of the plates 12 are similarly strengthened hy angle-plates 16. (Fig. 8.) The outer edges of the plates 12 are bent at a right angle and connected by plates 1'8 with the posts. The doors 13 may be locked in a closed position by fastening means shown in Fig. 5 of the drawings, consisting of e pair of bolts 18 slidably mounted on the outer faces of the end-plates it, and adapted for engagement with openings in plates 19,-fixed to the frame of the machine. The bolts 18 are connected by links 20 with the inner ends of a pair of levers 21. pivoted to the end-plates id, as at b. Atthe lower ends of the plates it are slidably mounted it pair of bolts 22, adapted to enter openings in the lower part of the frame, not shown in the drawings. The bolts 22 are united by links 23 with the levers 21, at points between the tulcrums and outer ends of said levers. A movement of either of said levers operates to simultaneously lock or release the holts connected therewith. The fastening means just described. when in a loclred position, provide as rigid resistance againstthe pres sure exerted in the receptacle, either in the direction of the side plates 13 or end plates i l. I

Secured to the outer faces of the posts till lttd

3 are spacers 25, to which is secured plots I tain devices used in controlling the operation of the machine, which will be hereinafter more fully set forth.

Fixed to the inner faces of the crossplates 10 is a pair of bearings 27, (Fig. 3) from which is supported a pair of shafts 28, so asto be rotatable therein. Said shafts are provided with threads 29, and the lower end of each of said shafts is united in'a bearing in one of the tie-ribs 4. The lower end of each of said shafts is threaded to receive a nut 31, above which is fixed to the shaft a helical gear wheel 32, separated from the bearing 30 by plates 33, provided in their adjacent faces with ball races for a series of balls 34.

On each of the shafts 28 is a traveller 35, internally threaded to correspond with the threads on said shafts, said travellers being fitted with trunnions 36, upon which are rockingly mounted bearings 37, from which shafts 38 are projected inwardly.

Rockingly supported on said shafts is' a cross-beam 39, by means of bearings 40 on the ends of said cross-beam. Fixed to the lower face of the cross-beam 39 is a series of channel-plates 41, comprising the compression member or platen of the machine, such platen being of a suitable, size to move vertically in the receptacle. 'A coincident rotation of the shafts 28 operates to move the travellers 35 and parts supported thereby upwardly or downwardly, depending upon the direction of rotation of said shafts.

Movement is imparted to the shafts 28 from a shaft 43 rotatably mounted in the base of the machine, and upon which are fixed gear-pinions 44, in engagement with the wheels 32 on the lower ends of the shafts 28. Movement of the shaft 43 is derived from an electric motor 45, in one end of the base, by means of a gear-pinion 46 on the motor shaft, in mesh with a gear-wheel 47 on the shaft 43. The pinion 46 is considerably smaller than the wheel 47 so that the speed of such wheel and the shaft 43 will be correspondingly reduced.

The upper ends of the shafts 28 are threaded, and titted with nuts 48, between which and the bearings 27 are inserted ballbearing plates 49 and 50, (Fig. 4) separated by balls 51. In the greater part of its movement portions of the cross-beam 39 near the ends thereof travel in the channels in the ends of the receptacle, and in continuations of such channels formed by ex tension-s 15 in the superstructure. When the platen is supported at a point where it is not in engagement with the material in the receptacle the weight of such platen and appurtenant devices will be sustained entirely by the bearings 27 and anti-friction devices thereon, but upon the platen being moved downwardly into engagement with the material in the receptacle, and beginning to exert a pressure thereon, the direction of the load is shifted, and a force exerted by the platen and travellers 35 in an upward direction upon the screws 29. The resistance of the mechanism at the upper ends of the shafts 28 is thereupon transferred to the lower ends thereof, the upward stress being borne by the anti-friction devices provided at that point. Said shafts 28 are capable of a limited amount of vertical movement in the

bearings

27 and 30, to allow for the transfer from one set of resistance devices to the other.

Connected with the outer ends of the bearings 40, so as to be rotatable therewith. are gear-pinions 53, the teeth of which are adapted to engage the teeth of a pair of This leaves the top of the vmachine clear for the delivery of material into the receptacle. ellers the platen is rocked back into position again, ready for its downward move ment. The superstructure is of a sufficient height to permit the platen to be carried to a considerable distance above the top of the receptacle, and the return movement of such platen is in a combined inward and downward direction, making it possible to pile the material above the top of the receptacle. the excess material being forced downwardly into the receptacle in its downward movement. This gives a greater capacity to the machine, than in those which can only be partially filled, or only filled as far as the upper edge of the box.

The operation of the motor may be under the control of well-known electrical devices, stationed in encasements on the outer face of the panel 26, as shown in Fig. 1. For example, the box 56 may contain a safety switch, under the control of a circuit breaking device in the casing 57, so arranged that when the amperage of the current reaches a pre-determined point, superinduced by the pressure exerted by the platen upon the contents of the receptacle, the circuit is automatically broken, and the machine ceases to operate. At 58 is shown an enclosure for other electrical devices of a standard type, the purpose of which is to cause the motor to operate in a given direction, or the reverse On the return movement of the travthereof. These devices are underthe control of switches in a box 59, provided with a set of push-buttons 60, one of which operates to start the motor to move the platen in a a downward direction, one to cause an upward movement thereof, and another to interrupt the movement of the motor and platen.

' Limit switches are also provided, one at 62 ly as shown in Fig. 7. It will be evident that, as a matter, of convenience, the racks 54 can be arranged on either side of the machine, and the platen tipped accordingly;

The trunnion support of the bearings gives a flexible connection to the ends of the cross-beam 39 with the travellers 35, and prevents the threads of such travellers becoming-jammed on the screws 29, in case a greater strain should come on one end of the platen and cross-beam than on the other.

In Fig. 9 is shown a modified arrangement of the device, wherein a platen is suspended by a cross-beam '66, supported at its ends on the shafts 38. replaced by segment-gears 67 which engage gear racks 68 in the upper part of the frame.

The pinions 53 are By such engagement, and the continued upward movement of the shafts 38 the platen is swung to one'side, as shown in broken lines in said Figure 9. The receptacle can then be filled through the top as in the former case. a

What I claim, and desire to secure by Letters Patent, is: e

1. A baling press, comprising a receptacle,

open at the top, and capable of being opened at its sides; a press mechanism vertically movable in said receptacle, and above the same, said mechanism being rockingly mounted at its ends; an impediment supported in the path of said press mechanism, near the upper end of the movement thereof; and means carried by said press mechanism capable of a mobile engagement with said im ediment, causing a tipping movement 0 said press mechanism to one side of the machine, during a continued upward movement of said mechanism.

2.1. A baling press, comprising a receptacle having an open top; a pair of screws vertically supported at opposite ends of said receptacle; travellers on said screws; :1 press mechanism pivotally connected at its ends I with said travellers, and including a -platen device; gear pinions on the pivots of said pressmechanism; and gear racks supported in the upper part of the machine, in the path fof said PIIIiOIlS, and adapted to rotate the same to rock the press mechanism and platen to one side. of the machine.

In testimony whereof I afiix my signature.
