Patented March 13, 190e,

` To all whom it 'may con/cern: P

Be it known that I, GEORGE WILLIAM BROWN, a Citizenof the United States, residing at Hyde Park, county of Norfolk, and Commonwealth of Massachusetts, have invented an Improvement in Cable-Reel Vlinders and Brakes, Vof which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

` mounted at one end in a fulcrum-block carried by the arbor ofthe reel and which has a ripping-block adapted to engage theinner fgace of the flangeof the reel, said grippingblock being so constructed that when the lever is moved in one direction it willgrip the flange of the reel and turn the latter and when the lever is moved in the opposite directionV it will .become 'released from the fiange, thereby permitting-the lever to be shifted into a new position for getting another grip.

The particularfeatures of .myinvention will be more fully hereinafter described and then pointed out in the following claims. l

In the drawings, Figure 1 is a perspective view showing my improved device applied. to

a reel. Fig. 2 is a section on line y y, Fig. 1.

Fig. 3 is a section through the leveron substantially the line Fig. 1. Fig. 4 is a detail of the locking device for the brake, and Fig. 5 is a detail of the fulcrum-block.

, 3 designates a reel of any suitable construction on which the lead cable or conduit is adapted to be wound. During the winding of the lead conduit on the reel or the unwinding of it therefrom said reel is usually supported on a suitable arbor 4, which is mounted in a support or jack 5, the latter frequently havingthe adjustable bearing 6, by means of which the arbor'may be raised or lowered.-

The parts thus far described form of my present invention.

My improved device comprises a lever 7,

no part 'l which is mounted at one end in a fulcrumblock 8, adapted to be carried by the arbor 4 and which carries a gripping-block 9, arranged to grip the face of the iiange 10 ofthe reel 3. The fulcrum-block 8 is shown as being made with the two arms 11, each of which has a transverse aperture 12, through which the le-- ver 7 extends. The slot between the two arms 11 of the fulcrum-block extends some distance beyond the apertures 12, so that when the block is slipped over the arbor, as shown in Fig. l, said apertures 12 are above the arbor and when the 'lever is slipped through the apertures the larbor is confined between the lever and the arms 11. .The lever is by this construction fulcrumed on the arborv 4. The gripping-block 9 is pivotally mounted on an arm 18, which in turn is pivoted to the lever 7. The arm -13 may have any ysuitable construction; but, as herein shown, it is constructed to present the shank portion 14, which extends along parallelto the .arm 7 and is journaled in suitable eyes-15 thereon, the transverse portion 16, which ex'- tends through an aperture in the lever 7, and

the grip block sustaining portion 17', on

which the grippingblock 9 is pivotally mounted. The' aperture through the lever 7 has' a substantially horizontalbottom 18 and an inclined upper side' 19, as shown best in .Fig. 3. The gripping-block 9 may beof any suitable or .usual construction, and preferably its gripping-face will be serrated or provided with projections 20, which are adapted to igrip the face of the iiange 10. I

n using the devicethe free end'21 of the lever is raised, and during such movement the gripping-block becomes released from the flange 1.0 and is carried up'into position to grip the flange again. As the lever is swung ownwardly the'gripping-block is carried f against the inner face of the flange 10 and is caused to grip the latter. The construction is such that the greater the force applied to the lever the greater will be the gripping action of the gripping-block, as will be obvio us.

The lever 7 is adjustably mounted in the l fulcrum-block 8, so that the device may be used with reels having flanges 10 of diiferent sizes. As hereinshown, said lever is provided with a plurality of apertures 22, and each arm 11 is also provided with an aperture 23, andy the lever is heldin its adjusted position by a suitable pin 24, which is inserted through one of the apertures 23 and an aperture 22 kof the lever. One of the apertures roo,

23 is slightly nearer the closed end of the slot cable-reel, and a gripping device carried by between the arms 1l, and the pin 24 will be said lever and adapted to engage the inner inserted in one or the other of the apertures 23, accordin to the size of the arbor on which the ree is mounted.

In connection with my improved grippinglever for turning the reel I employ a brake for preventing the backward movement of the reel. This brake comprises a brake-block 25,.which is shown as pivoted to a base-piece 26 and whichY is shaped to engage the rim of the flange 10 and prevent it from turning backwardly. Said brake-block is held against the rim and in operative position by a suitable spring 27. The base-piece 26 is made adjustable, so that the brake may be used with flanges of different sizes. For holding the base in place I have herein shown a dog 28, which is shaped to embrace the stand 5 of the jack and which has a nose 29, adapted to enter one of a series of notches 30 in the top of the base-piece 26.

It will be seen that the construction of my device is very simple, that it is effective in operation, and that it can be adjusted so as to bevused with reels of different sizes.

The device herein illustrated is a preferred embodiment of my invention; but it will be obvious that various changes in the construction of the device may be made without departing from the invention.

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, isf 1. In a device of the class described a fulcrum-block adapted to be detachably secured to the arbor of a cable-reel, a lever mounted in said fulcrum-block and extending transversely to the axis ol the reel, and a pivoted gripping-block carried by the lever and adapted to grip the flange of the reel.

2. In a device of the class described, a fulcrum-block to embrace the arbor of a cablereel, a lever adjustably mounted in said fulcrum-block and extending parallel to the flange of the reel, and a gripping device carried by the lever and adapted to grip the flange of the reel.

3. In a device of the class described, an adjustable lever fulcrumed on the arbor of a face of the flange of the reel.

4. In a device of the class described, a fulcrum-block adapted to be mounted on the arbor of a cable-reel, a lever adjustably mounted in said fulcrum-block, and a gripping-block pivoted to the lever and adapted to engage the inner face of the flange of the ree 5. In a device of the class described, a bifurcated fulcrum-block adapted to straddle the arbor of a cable-reel, each arm of said fulcrum-block having an aperture therethrough, a lever extended through said apertures, and a gripping-block carried by the lever and adapted to engage the inner face of one of the flanges of the reel.

6. In a device of the class described, an adjustable lever fulcrumed on the arbor of a cable-reel, a gripping device carried by said lever and adapted to engage the inner face of the flange of the reel, and a brake to engage the rim of the reel and prevent backwar( rotation thereof.

7. In a device of the class described, an adjustable lever fulcrumed on the arbor of a cable-reel, a gripping device carried by said lever and adapted to engage the inner face of the flange of the reel, andJ a brake comprising a pivoted brake-block to engage the rim of the reel and prevent backward rotation thereof.

8. In a device of the class described, a fulcrum-block adapted to be mounted on the arbor of a cable-reel, a lever adj ustably mounted in said fulcrum-block, a grippingblock pivoted to the lever and adapted to engage the inner face of one of the flanges of the reel, and an adjustably-mounted pivoted brake-block to engage the rim of the reel and prevent backward rotation thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE WILLIAM BROWN.
