RICHARD LABORIDA, 0F SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO PETER CUELLAS, 0F SAN FRANCISCO, CALIFCRNIA.

CLIMBING DEVICE.

Specication of Letters Patent.

Patented Sept. 15, 19141` Application filed April 27, 1914. Serial N o. 835,310.

To all 'whom 'it may concern the city and county of San Francisco andV State of California, have invented a new and useful Improvement in Climbing Devices, of which the following is a specification. Y

My invention relates to improved climbing devices wherein a tubular member having o'set ends is provided with a climbing pulley adapted to engage a suspended rope run through the tube and wound around the said climbing pulley, which is operated by means of oscillating pedals, and is particu-A larly adapted for ascending or descending a suspended rope as a lire escape, or, in ascending or descending from buildings and similar structures in course of erection, and the objects of my invention are, first, to provide improved means for climbing a rope; second to provide improved means for preventing an involuntary descent of the climbing device; third, to provide improved oscillating pedals operating independently and adapted to rotate the wheel and climb the rope; and fourth, to provide independent oscillating pedals which are adapted to operate suitable band brakes as well as the climbing wheel. I accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout the said specification and drawings, and in which- Figure 1 is a broken side elevation of a device disclosing the offset ends and the seat secured thereto in a position substantially in alinement with the suspended rope above the device; the manner in which the suspended rope is run through the tube and around the pulley; the pawl and ratchet for normally preventing a reverse rotation of the climbing pulley and the manner in which pawls pivotally secured to the under surface of the oscillating pedals are engaged to the ratchets which are in turn secured to the climbing pulley. Fig. 2 is a rear elevation of Fig. 1. Fig. 3 is an enlarged elevation of the climbing pulley disclosing the manner in which the suspended rope passes through the tube and around the climbing pulley, the manner in which the internal ratchet on the said climbing pulley is nor- `mally engaged by a pawl pivotally secured to the frame, the manner in which pivoted `pawls on the pedals engage the ratchets secured to the climbing pulley and the manner in which band brakes engage the hub of ythe climbing pulley and the springs which -normally raise each oscillating pedal inde-l pendently of the other pedal, and Fig. 4, is a broken rear elevation partly in section disclosing the sleeve rotatably mounted upon the frame work of the device, the climbing pulley and the ratchets secured to the outer end of the4 sleeve and beyond the frame work, and the oscillating pedals loosely mounted on either end of a shaft rotatably mounted within the sleeve.

Referring to the drawings, the numeral 1 is used to designate a vertically disposed tube having upper and lower offset ends 2 and 3, respectively. An open frame 1 is secured to the tube and arranged intermediate of the ends thereof. Rotatably mounted within the frame 4 is a sleeve 5 to which is yrigidly secured the climbing pulley 6 provided with an internal ratchet 7 which is normally engaged by means of a pawl 8 pivotally secured to the frame 4- and having connection, by means of a rod 9, with a handle 10 secured to the tube 1. rEhe climbing pulley 6 has a tread around which is wound a suspended rope or cable 12 that passes through the tube 1 and around the pulley 11 set within the tube 1 for the purpose of reducing to a minimum the friction of the said rope 12. Y

A ratchet 15 is secured to eachend of the sleeve 5. A shaft 16 is rotatably mounted within the sleeve 5 and has loosely mounted on either end thereof the oscillating pedals 17. lThe pedals 17 are normally raised by means of suitable springs 18 loosely wound around the outer ends of the shaft 1G, one end of each spring being arranged to engage the frame 4, while the other end thereof engages the pedal 17, so that the tendency of the springs 18 will be to normally retain the pedals 17 in an upper position against lugs 20 which are integral with the said frame 4:.

Pawls 21 are pivotally secured to the under side of each pedal 17 and arranged to engage the teeth of the ratchet 15 secured to the outer end of the sleeve 5. Each pawl 21 is provided with an extension 22. Band brakes 24 each have one end secured to a pin of a frame l and after passing around the hubs of the climbing'A pulley 6 has the other end thereof secured'toa 'pin26' of the"` lever 27, which normally rests against pins 28 secured on either side of the frame 4. A

suitable saddle 30 is adjustably secured to4 l the tube l for the support of Vthe operator.

ll-he operation is as follows: lThe operator: is seated upon the saddle 30 andby moving.

either Vpedal 17 downwardly alternately causes the 'pawls21 thereof to Ilengage `the ratchets 15, which are secured to either end of the sleeve 5to which is also securedthe climbing pulley- 6. vAsthe pedals 17 are lalternately moved downward, the, climbing pulley 6 is ,rotatedand climbsthesuspendedy rope 12.

' tinued alternating.oscillation yof the pedals 17 .within a certain arc will cause thepulley 6 `to `rotate-.and climb :the rope 1 2.

In order .to .lower the .device :either one .for bothof; the/pedals 17 are. pressed f downward until the extension 22 ofthe-pawl21 engages the band brake lever ,2.7. As thereis considerable weight being supported by the pawls 21, considerable. pressure ,is required during adownward pressure. of either pedal 17 to;dislodge the 4p awl21 from .theratchetl A spring 35 is provided between each.
