BOTH OF SAME PLACE.

CABLE-GRIP.

SPECIFICATION forming part of Letters Patent No. 464,878, dated December 8, 1891.

Application filed July 29, 1891.

To MZ whom t may concern.-

Be it known that I, Louis KANNnNsrINn, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Ilnprovement in Cable-Grips, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming-part of this specification.

This belongs to that class of grips adapted to release the cable and to take it up again and to give support to the cable when it is running free.

The novel features are set forth. in the claims. l

Figure I is "a side elevation of the grip in position for engagement of the cable. Fig.

YII is a similar view in position for taking up the cable. Fig. III is an end elevation of the lower portion of the grip with the parts as seen in Fig. I, portions being broken ont. Fig. IV is an end elevation of the lower portion of the grip with the parts shown in the same position as in Fig. II. Fig. V is an enlarged vertical transverse section taken at VI VI, Fig. I, showing the jaws in gripping position. Fig. VI is a similar section, except that the jaws are shown in depressed position. Fig. VII is an enlarged det-ail elevation giving an inside View of one of the grip-jaws and contiguous parts.

1 is the horizontal supporting-bar, having lugs 2 to receive bolts by which itis attached to the frame of the grip-car.

3 are upright bars fixed to the supportingbar and connected by plates 4: and 5, fastened to them upon each side, the plates fl forming side guides to the vertically-movable plate 6, that carries the grip-jaws 7, and the plates 5 forming guides for the jaws and means for forcing them together as the plate 6 is drawn upward. The plate G has at its upper end a vertical cograck 8, that engages acog-quadrant 9, pivoted to the plates 4 at l0. Upon the quadrant is a hand-lever 11, carrying the usual dog 12, that engages a curved ratchet 13 (as usual) to hold the lever 11 and suspension-plate 6 in any desired position. This dog is forced down by a spring 14 and lifted to disengage it from the ratchet by a rod 15 with a small hand-lever 1G. The device for Serial NOAOLWO. (No model.)

holding the hand-lever is well known and no novelty is claimed in the same.

The grip-jaws 7 are counterparts of each other. 'They are connected at the upper edges by hinges 17 to brackets 1S, that are bolted to the sides of the suspension-plate G. The jaws are forced outward by springs 19 and are pressed inward as they are drawn upward by the pressure of their outer sides against the inner sides of the plates 5. It is preferred to provide anti-f riction rollers 20, that have bearing in the plates 5, and whose peripheries bear against the jaws or against inclines 21 thereon. By moving the lever ll from the position shown in dotted lines in Fig. I to that shown in full lines in the same figure the jaws 7 are forced inward and grip the cable 22. (See Fig. V.)

23 are the removable grip-plates having grooves 24: to receive the'cable.

25 are wheels or rollers upon which the cable is ordinarily supported when it is running free. to the jaws.

The grip-jaws have several positions: first, when gripping the cable, which position is shown in FigsI, III, and V, second, when the jaws are slightly opened from the position seen inFig. I by moving the lever 11 from position shown in full lines to position shown by dotted lines, so as to free the cable and to allow it to run upon the sustainingwheels 25; third, when the jaws are spread sufiiciently to allow the cable to drop between the wheels 25; fourth, the position shown in Figs. II, IV, and VI, when the jaws are in position to take up the cable, and, fth, when the jaws are closed upon the cable, which is done by means ofa treadle whoselower end is forked and embraces the jaws, so as to force them together and carry the wheels 25 beneath ythe cable.

cated by dotted lines in Fig. VI. The means These wheels turn on arbors fixed This position of the wheels is indiy IOO r purpose of the spring is to raise the treadle in Fig. I.

and sustain it in its normal position, as seen The treadle is shown in its lower position in Fig. II.

Fig. II indicates the position of the parts when .the cable has just been taken up, but the jaws have not been elevated into working position. In order to do this, the lever l1 is moved from the position shown in Fig. II to the position shown by dotted lines in Fig. I, which will lift the cable, but not grip it. VThe treadle will be elevated with the jaws 7. As .soon as the lever has reached the position shown by dotted lines, Fig. I, the foo-t may be removed from the treadle, vas it will no longer be needed to hold in the jaws 7. The cable may now be gripped by moving th'e lever to the position shown by full lines in Figi.

I cla-im as my invention-- l. 'The combination, in a cable-grip, of the grip-jaws hinged to a vertically-movable plate 6, means for imparting such movement to the plate, plates 5, acting to press the jaws inward Y upon the cable on the elevation of the plate 6, and springs 19, acting to force the jaws eutward, substantially as set forth.

.2. The combination, in a cable-grip, of the jaws 7, hinged to the vertically-movable plate 6, and a treadle-bar 27, having projections 30 embracing the jaws, substantially as and for the purposeset forth.

3. The combination, in a cable-grip, of the Q vertically-movable suspension-plate 6, gripjaws 7, hinged thereto, the bars 5, adapted to press in the jaws as they ascend, and the treadle-bar having projections 30 embracing the jaws and adapted to press them together at any desired elevation of the jaws, substantially as set forth.

4. The combination, in a cable-grip, of the hinged' jaws 7, a vertically-moving treadle having projections 30 embracing said jaws,a spring 33, acting to lift the treadle, and a footrest 26, all substantially as and for the purpose set forth.

5. The combination, in a cable-grip, of a vertically-movable suspension-plate 6, carrying hinged jaws and adapted to drop the lower parts of the jaws below the working position of the cable, and a treadle having projections 30 embracing the jaws and adapted -to c-lose the jaws when in their lower position, substantiallyas set forth.

6. The combination, in a cable-grip, of the suspension-plate 6, means for imparting vertical motion to the`plate, grip-jaws hinged to the lowerpart of the suspension-plate, springs 19, pressing the jaws outward, cam-plates 5, pressing the jaws `inward on their ascent-and carrying anti-friction rollers 20, inclines 2l on the jaws, adapted to be'ar against vthe rol-lers 20, and wheels 25 at the lower partsofthe jaws, adapted to sustain the cable, all substantially as set forth.

7. The combination, in a cable-grip, of the suspension-plate 6, having vertical movement, means for imparting such movement, jaws k7, hinged `to the yplate and wheels 25, the cam-plates 5, carrying rollers 2l, adapted to bear on the inclines, and a verticallymovable treadle with projections 30, adapted to embrace the with a foot-rest and a lifting-spring,substan tiallyas set forth.
