Figure 1 is a plan view of my shipper showing'it in operative relation to a bull wheel;

Fig. 2 is a perspective view of the ship per, and

Fig. 3 shows a slight modification.

The bull wheel 1 may be of the usual orv any preferred construction and the bull rope 2 is trained Varound the same in the usual manner. Adj acent the bull wheel, I provide a supporting frame consistingof a strap or bar 3 having its ends downturned, as at 4, to constitute supporting legs and having the lower terminals of said legs spread outwardly to form feet 5. Encircling the legs 4 is a rim or ring 6 which is provided with notches in its lower edge at diametrically opposite points to fit over the feet 5 whereby the lower edge of the said ring mayV rest upon the ground or the platform. At diametrically opposite points, between the said notches, the ring is provided with lugs or feet 7 throughwhich fastening devices may be driven into the ground or the platform upon which the apparatus is mounted, it being understood that the feet 5 are secured in place in the same manner. The height of the ring is somewhat less than the'height i of the legs 4 so that thecross bar or metallic strap 3 will be disposed in a plane slightly above the upper edge of the ring. Resting on the upper edge of the ring and passing is provided at one end with an upstanding.

pin or roller' 11 and at its opposite end is provided with a plurality of openings 12, in any one of which the end of a handle'v `13 may be engaged. This handle 13 may be a rod or pipe of any desiredA length and is, of

under the bar is a shipping lever 8 which course, to be grasped by the operator when the rope or belt is to be shipped. i o VVhen the apparatus is in operation, the shipping lever extends preferably parallel with the bull rope, as'shown in Fig. 1, so that the shipping pin or roller .11 will be away fromthe rope and not apt 'to accidentally come into contact therewith. `When the operation is to cease, a pull is exerted .65 upon the handle 13, thereby swinging the shipping lever ;about its pivot and carrying the pin or roller 11 into' contact with the bullrope, as indicated by dotted lines in Fig. 1, it being understood that thev device should be so located that the distance radially of the ring 6 between thecenter of the ring and the bull rope is less than the distance between the center of the ring and the'shipping pin 11. The shipping lever will be firmly supported by the ring but at the same time may move easily thereupon when shipping of the rope is .desired, but the lever cannot be swung to such an extent that, it will become entangled with. the rope Vor brought into contact with the. full rwheel inasmuch as the legs 4 constitute stops to limit` the shipping movement of the lever, as will be readily understood upon reference to the dotted lines in Fig. 1. VThe device is eX- ceedingly simple in construction and' may be very readily applied to existing apparatus. i

While it is desirable to construct the fulcrum bar or strap and the base ring or rim as separate elements, they may form one integral structure, and in Fig. 3 are so illusv trated. In said form, the fulcrum bar` 13 extends diametrically across the base ring'l 16 and has downturned ends `14 which are integral withthe upper edge of the ring and correspond'in height to the thickness of the shipping lever. All the feet 17 are integral with the .lower end of the base ring.V

i Havingthus described the invention, what '100' t is 'claimed as new is:

1. In a bull rope trip, the combination of a lring having means whereby it may be secured to a vfiXed support, a supporting bar extending diametrically across the said ring and having legs fittingpwithinthe ring and against the same and provided at the lower ends of the legs with feet extending through the ring'and adapted to be secured to a fixed support, and a shippingglever extending across the ring` and underv the said bar and pivoted to the bar concentric with the ring.

2. In a bull ro'pe trip, the combination of.

metricaly across said ring, said bar havingV legs fittng within the ring and provided at their lower ends With feet extendng thrugh correspondng notches in the ring and adapted to be -secured to 'the fixed' base, and a rings, sadlgs forming stops 'for lmitng the tripping movement of sac' lever.

n t'esgtlmony Whereof I afli): `my slgnature.
