CABLE-RAILWAY GRlP.

SPECIFICATION forming part of Letters Patent No. 351,086, dated Qctober 19, 1886.

Application filed April19,1886. Serial No. 199,377; (X0 model.)

To all whonr it may concern.-

Be itknown that 1, DAVID B. ANDnRs, a citizen of the United States, residing at Philadelphia'and State of Pennsylvania, have invented new and usefulImprovements in Cable- Railway Grips, of which the following is a specification.

My invention relates to improvements in cable-grips in which the gripping-jaws can be lowered to grapple the rope by the man standing on the platform of the car. By the use of my improvements the rope may be dropped at any time to a lower level than the path of the gripping device, and again raised into the grippiugjaws at the will of the gripman with perfect ease and safety. The mechanism by which I attain these objects is illustrated in the accompanying drawings, in which- Figure 1 isa side elevation; Fig. 2, an end elevation with slot-irons and upper portion of conduit in dotted lines, the curve rail on which the curve wheels roll, and a section of curve pulley. Fig. 3 is a crossscction through the line CD, Fig. 1. Fig. etis a section through A B.

Similar letters refer to similar parts throughout the several views.

Upon suitable hanging bars, a", which may be supported from the axles or any other part of the car, are cross-pieces y, from which the head-piece V is supported by the pins or rods 9'. The headpiece V has thin plates 1), securely riveted or bolted to it, and adapted to slide through the slot in the conduit. The lower portions of theplatcs 1) form guides upon which the grip-carrying sleeve S slides with a vertical motion. To the sleeve S is attached the lifting-bar Z. At the bottom of the sleeve S are the bosses 8, into which are inserted the pins 0'. The pins 0" pass through the armsg on the gripjaws G and form the center or fulcrum upon which the gripjaws are suspended and operated. The operatingbar 0 passes freely through the sleeve S and is secured to the crosshead I. In the ends of the cross-head t are fitted sliding boxes t. (Small steel rollers may be substituted for the boxes.) Through these boxes the rods or pins 9': pass, connecting the pair of arms y 011 each grip-jaw. The jaws G have removable faces 9', that receive the wear from the cable. Hinged to one side of the sleeve S is the swinging piece H, carrying curve wheels or rolls h and spools if at the lower extremities. To the swinging piece H is attached thelink 2', connected with the bar '2'. Curve wheels are also provided on the opposite side of the sleeve S from the swinging piece H. The bar t is raised or depressed by the bell-crank fulcrumed to the lifting-barl and connected to suitable lever by the rod j. The operating-bar 0 is also raised or depressed by a similar bell-crank and lover. The lifting-bar Z is supported by the links 1:, attached to the top of the lifting-bar and the head-piece V and operated by suitable lever. The connecting-rods j, j, and j maybe carried to both ends of the ear, with suitable operating-levers on both platforms.

The operation is as follows: To grapple the rope or'cable which is running on sheaves below the grip, the bar iis first raised, swinging the piece H aside, so that the spools it" will not interfere with the rope entering the jaws. lhe opcratingbar 0 is then forced down,opening the jaws. The lifting-bar Zis then lowered until the jaws pass over the rope, when the bar t is depressed and the spools h" swung under the rope. The liftingbar. Z is then raised until the spools are higher than the sheaves uponwhich the rope runs. By raising the operating-bar o the jaws are forced ,against the rope, imparting the motion of the rope to the car. To stop the car, it is only necessary to loosen the jaws from the rope slightly and apply a brake to the wheels of the car; but when it is necessary to drop the rope the spools h are swung from under the rope and the grip-jaws opened until the rope falls.

Vhat I claim as my invention, and wish to secure by Letters Patent, is

1. The grip-supporting sleeve adapted to move vertically upon a guide or plates suspended fro m the ear, substantially as described, and for the purpose specified.

2. The combination of the sleeve S, gripping-jaws G, plates 1), and bar Z, substantially as described, and for the purpose specified.

- 3. The combination of the sleeve S, plates 1), bar Z, jaws G, with arms 5/, 'crosshead t, and bar 0, substantially as described.

t. The combination of the sleeve S, plates 1), bar Z, and means to raise and lower the so me,

jaws G, with arms 9, cross-head 15, bar 0, and

means to raise and lower the same, substantially as described, and for the fied.

5. In a cable-railway grip, the combination of the gripping-jaws G, with arms crosshead t, pins 1, bar 0, sleeve S, swinging piece H, and spools 7L2, substantially as described,

purpose speciand for the purpose specified.

6. In a gripping device for rope or cable railways, the combination of a sleeve carrying gripping-jaws,with means to operate the same, cable-supporting spools,with means for swinging them to one side to allow the cable to enter the jaws, the whole adapted to move verti- DAVID B ANDERS.
