EDWARD J. HOODE, OF BENSON, MINNESOTA.

CABLE-TENSION HOLDER.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed May 12, 1908. Serial No. 432,353.

To all whom it may concern:

Be it known that I, EDWARD J. l-Ioonn, a citizen of the United States, residing at the city of Benson, in the county of Swift and State of Minnesota, have invented certain new and useful Improvements in Gable- Tension Holders, of which the following is a specification.

My invention relates to new and useful improvements in the manner and means of regulating the boom of a dredging vessel, or, in fact, any boom may be regulated by the application of my device.

The object of my invention is to keep the boom-cable taut at all times, thus giving the operator, full control over the regulation of said boom. It is pointed out that in order to turn the boom at any desired position, it is necessary to have considerable tension onsaid boomcable, and the object of myinvention as briefly stated heretofore is to lace any desired tension on the boomcab e, and means to hold said cable at such desired tension.

If, through constant use, the boom-cable should become stretched or should snap, said cablecould be repaired or a greater tension placed thereon, by the use of my invention, which will be described more fully.

With these and other objects in view my invention consists of the novel construction and arrangement of parts as are hereinafter described, and specifically pointed out in the claims hereunto appended.

Reference being had to the drawings, which are for illustrative purposes only, and are therefore not drawn to scale Figure 1, is a side elevation of my device illustrated in connection with a dredging boat. Fig. 2, is a top plan View, on an en large'd scale, partly in section, showing the relative arrangement of the drums and shives. Fig. 3, is a central, vertical, sectional view taken on line 3-3 of Fig. 2. Fig. l, is a face view of one of the small drums. Fig. 5, is a side elevation thereof, partly in sec tion. Fig. 6, is a face view of one of the large drums, and Fig. 7, is a side elevation thereof, partly in section.

Referring more particularly to the drawings, the boat or barge 1, has the pivoted upright 53, mounted at the bow thereof, said u right'bein held firmly in place by means 0 brace 3. ivotally connected to said upright near its lower end is the boom 1, which is operated in a vertical plane, by means of the cable 5. The grooved wheel (5, is securely mounted to said upright near the lower pivotal point. This wheel together with said boom-cable is the means by which said boom is operated in a horizontal plane. The shaft T, which is pirotally mounted on the supports 6, has keyed to one of its ends outside of said supports, a gear wheel 5), said wheel being the means by which power is transmitted to said shaft, the means of furnishing power not being shown. The large drums 10 and 11, and the small drums 1'2 and 13, are loosely mounted on said shaft. The large drums have on their inner ends enlarged flanges 1-l, adapted and for the purpose of engagement with the friction-block 15, said friction-block being thrown in and out of engagement with said flanges 14, by means of the lever 16, which is pivotally secured to the frictionbloclr at l7, and which is fulcrumcd to the cross piece 18, secured to the upright braces 19, said lever held in position by spring actuated bolt 16, working in notches 16*. Said drums l0 and 12, are held against sidewise movement by means of collars 20 and "il, respectively. Said drums 11 and 13, are likewise held against sidewise movements by means of collars 2" and 23, said collars being adapted to be adjusted on said spindle by means of set screws. Each pair of drums consisti [1g of one large and one small drum are held in engagement with each other by means of interi'neshing teeth 2 1-.

lheboom-cable 25, which is entwined around large drum 11, its end held firmly in place by oinding post. 26, passes first, around the shive 27, then around said grooved wheel 6, then around the shive then around said drum 10, its other end being held firmly by means of binding post 26. The tension-cable 22, having one end secured to binding post 30, passes around sn'ive 31, then around shivc and lastly is entwined around small drum 13, having its other end secured to binding post 33.

The operation of my invention is described as follows :\Vhen it is desired to cause the boom to assume a dili'erent position in a horizontal plane, friction-block 15, is thrown into engagement with one of the flanges 11. For instance should it be de ill! s'red to turn the wheel 6, in the direction of the arrow then friction-block will be thrown into engagement wita the flange of large drum l0. l fhen the boom-cable is traveling in the direction of the arrows, said large druni- 10, being in engagement with small dram 12, causes that drum to rotate in conjunction with the large one. its the cable is caused to unwind from lar e drum 11, small drum 13, is caused to rotate in conjunction therewith, thus causing said tension-cable to entwinearound said drum l3, and at the same time unwind from said drum 12. Thus it will be seen that whatever tension is exerted on the boom-cable will be exerted on the tension-cable, and vice-versa. If drum 11, were not held in check sutlicient pressure would not be brought to bear against the periphery of the wheel 6, to operate said pivoted upright. Should it be desired to tighten said boom-cable or lessen the tension thereon, it may be accomplished in either of the following ways :First, drum 11, may be held against rotation by means of friction-block 15. Drum 123, is then disengaged from drum 11, after first loosening colla 23, on the shaft. Said drum 1-5, is then turned in the direction of the arrow shown on the flange thereof, thus tightening the tensioneable causing drum 1:2, to rotate, which in turn causes drum 10, to rotate, finally tightening the boom-cable. Said drum 13, is rotated by any substantial means, but a spanner-wrench is preferably used, the lug thereof being inserted into one of the holes in the outer flange of the drum 13. This explanation also applies to said drum 12. The other method for tightening the boom-cable is to hold either of said drums 12 and 13, against rotation by means of a spanner-bar preferably, and causing the rotation of that particular large drum, which will be necessary to tighten said cables. When the desired tension is gained the teeth of said drums are allowed to again intermesh with one another. l

I Though I have specifically described my invention, I may claim the right to make such modifications and alterations in the minor details of construction and arrangement thereof, as will not departfrom the spirit of my invention, and as will fall within the scope of my claims, and which will be obviously necessary in its manufacture.
