3 Claims.

Our invention relates to a manually operated press in which tobacco, after being stripped from the stalks and hung on sticks, can be pressed into bales to retain it in a case condition so that it can be easily handled.

One object of the invention is to provide a press of this character which is collapsibly constructed so that it can be easily taken down, moved to another location and then quickly set up for further use. The collapsible construction also permits the bale to be removed intact instead of being taken apart one stick at a time, as might be necessary if the tobacco was pressed in a xed baling chamber.

A further object is to provide a simple and inexpensive tobacco press which is free of pawls, ratchets, sprockets, gear wheels, and similar mechanisms the presence of which would add considerably to the cost of construction and maintenance.

Another object is to arrange the working parts in' such manner that the press can be manually operated by one or two men.

Other objects will hereinafter appear and in order that the invention may be readily understood reference will now be had to the accompanying drawings, in which:

Fig. 1 is a side elevation of the press with a portion of one of the windlasses broken away and the Shaft thereof in cross section.

Fig. 2 is an end elevation of the press.

Fig. 8 is a detail perspective View of one of the standards forming a portion of the frame.

Fig. 9 is a'broken detail of the upper portion on one of the standards with cable tensioning means mounted thereon.

Fig. 10 is a detail cross sectionv of a portion of the tensioning means.

Fig. 1l is a detail perspective view of one of a plurality of antifrictional devices employed in carrying out the invention.

In carrying out the invention we provide a baling chamber 2 closed at its bottom portion by a platform 4 fixed upon a pair of horizontal beams 6 forming the lower portion of the collapsible frame of the press and resting near their ends upon a pair of sills 8. l

' The baling'chamber 2 is open at `both sides asclearly` Showny by Fig. 4, so that it may `be charged from both sides lwith the tobacco A which is usually supplied in the form of hands B mounted upon sticks C. The vertical ends of the baling chamber 2 are closed by end walls I0 each of which is xed `to a pair `of standards I2 fixed at their .lower ends Vupon the sills 8 and constituting a portion of the frame of the press. The beams 6 are equipped with fixedly mounted angle irons I4 which abut the sills 8 and hold the same in spaced relation to each other.

The upper portions of the end walls I0 are held in spaced relation to each other by means of a removable beam I6 which bears at its Aends against the inner surface of said end walls II). The beam I6 is provided at its terminals with angularmetallic straps I8 which engage the upper edges and the outer surfaces of said end walls and coact with the beam I6 in holding the end walls in spaced relation to each other.

The tobacco is compressed to the desired density in the press by meansA of a plunger 20 reciprocably mounted within the baling chamber 2 and including a pair of horizontal beams 22 slidably engagingthe standards I2. The plunger 2] is manually operated by means of a pair of windlasses 24, a pair of upper cables 26 and apair of lower cables 28. The windlasses may be of any suitable form. In the present instance each windlass comprises ahand wheel 39 and a horizontally disposed shaft 32 uponone end of which latter the hand wheel 30 is xedly mounted. The

shafts 32 are journaled in bearings 34 fixed upon the beams 22 of the plunger 20, and each shaft 32 is removablyheld in its respective pair of bearings 34 by Suitable means such as retaining pins 36.

The upper cables 26 cooperate with the respective windlasses 24 in raising the plunger 20, and each cable A26 is attached vat its upper intermediate portion to tensioning means comprising a shaft 38'journaled in bearings 40 secured to the upper endsof the standards I2. The shafts 38 maybe rotated forwardly to wind the cables thereon with a wrench or other suitable tool, not shown,v until the cables, 26 have been tensioned to thel desired degree, whereupon said shafts 38 are then secured from accidental backward rotation by pins 42 inserted through openings 44 in the bearings 40 and two of the diametrically opposed openings 46 in the shafts. The lower end of each cable is spaced apart as shown on Fig. 2 and secured to the respective windlass shaft 32 upon which it is adapted to be wound for the purpose of raising the plunger 20.

The cables 28 are spread apart at their lower ends and attached to eye-bolts 48 secured to the sills 8. The cables Z8 are attached at their intermediate portions by eye-bolts 50 to the respective windlass shafts 32vupon which they are adapted to be wound for the purpose of pulling the plunger 20 downwardly upon the tobacco to compress the same. By spreading the ends of the

cables

26 and 28 apart as stated, they cooperate with the shafts 32 and beams 22 in lholding the plunger 20 in a horizontal plane.

The

cables

26 and 28 are so attached to the respective shafts 32 that the cables 26 unwind as the cables 28 are wound upon said shafts and vice versa. In order to relieve the

cables

26 and 28 of the excessive wear to which they would be subjected if permitted to rub against each other, We interpose antifriction members 52 between said cables to hold them out of frictional engagement'witl'reachother. The antifriction members 52 are preferably arranged in pairs and loosely mounted upon'the respective'shafts'32 yso that said antifriction members 52 may rotate independently of eachother and also be moved axially upon the shafts 32 by the convolutions of the

cables

28 and 28 as they wind and unwind from the shafts 32. The'shafts 32 are also equipped with antifriction members 54 which prevent the convolutions of the cables 26 from coming into frictional contact with the standards l2 as the cables 2G are wound upon the respective shafts 32. The antifriction members 54' are held in spaced relation to the bearings 34 by spacing sleeves 56 loosely mounted upon Athe shafts 32.

After the plunger 20 has been pulled downwardly to compress the 'tobacco to the desired degree it is held in downward position for'a suitable period by detents 58. Each detent 58 is provided at one end with fixed jaws 60 for engagement over one of the spokes of the adjacent hand wheel 30,' and is pivotally connected at its other end to a respective bearing 62 secured upon the plunger 23. I v l v When it is desired to remove the bale of tobacco from the baling chamber, or remove the press from one location to another it may be readily taken down by removing the upperbeam I6 from the end walls I0, after which the retaining pinsv 33 are removed from the bearings 34 so that 'the shafts 32 can be rolled upwardly on the cables 26 to clear said bearings.` The standards l 2, with the' end walls l il, are then lowered so that the plunger 29 with its beams 22 can be lifted from the bale, which latter may then be removed intact from the platform 4. When it is desired toset the press up for further use lit can bel readily reassembled for that purpose.

For protection of the rcompleted bale itfmay raised and the sticks C are withdrawn from the hands B. A sheet is then spread over the top of the bale which is again compressed by lowering .the plunger 2U. The ends of the two sheets are comprising a platform at the lower end of the baling chamber of the press, two pairs of standards adjacent to the ends of said platform and forming the corners of the balingvchambenka wallfsecured to each pair of standards forl closing theends'of the baling chamber, a horizontal beam connecting the upper portions of the closed ends of the baling chamber, a plunger reciprocably mounted in the baling chamber and including apair of horizontal beams slidably engaging the standards,A and manually actuated means for operating said plunger.

2. A collapsible baling press comprising a pair of transverse sills, two pairs of standards fixed upon said sills and forming the corners of the baling chamber of the press,r a wall uniting each pair of standards and closing'the ends of the baling chamber, a pair of horizontal beams resting uponv the ysills yand bearing against the standards to assist in holding the latter in upright position, Ya platform forming the bottom of the baling chamberand luniting said beams with which they cooperate in supporting the standards in upright position, a removable upper beam bearing against the upper portions of the end walls to cooperate therewith in supporting the standards in upright position, elements fixed to'thefends'of said upper beam and removably engaging the upper portions of the end walls, a plunger operably mounted in the baling chamber and including a pair 'of beams slidably engaging the standards, and manually controlled means for operating said plunger. v

3. A tobaccopress comprising a baling case, a plunger reciprocably mounted within said baling case,l a pair of windlasses mounted uponsaid plunger to reciprocate therewith, shafts paralleling the windlasses and rotatably mounted at the upper portion of the baling case, cables attached at both ends to the respectivewindlasses and at their intermediate portions to the respective shafts, means for rotating the shafts to tension the respective cables, cables attached at both ends to the lower portion of the baling case and attheir intermediate portions to the respective windlasses at a point betweenv the ends of the mst-mentioned cables, and antifriction'members loosely mounted upon the respective windlasses between the first and last-mentionedA cables to prevent said cables from frictionally engaging each other as they are alternately wound upon and unwound from the windlas'ses to raise and lower the plunger.
