To all whom it may concern.'

Be it known that I, RICHARD LABORDA, a subject of the King of Spain, residing in the city of Oalrland,county of Alameda, and

State of California, have invented a new and useful Improvement in Climbing Devices, of which the following is a specification.

My invention relates to climbing devices wherein a climbing wheel operates in conjunction with a driving wheel and a suspended rope, and a bandbrake arranged to control the descent of the device; and the objects of my invention are first, to provide improved means for elevating a person or weight by pulling on the lower end of the suspended rope; second, to provide an improved device suspended from a suspended rope that maybe caused to ascend the rope by pulling on the lower end thereof; and third, to provide improved means that will release Vthe climbing wheel from the driving wheel when the Vlower yend of the rope is pulled to a certain position.

I accomplish these several features by means of the device illustrated 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 brokensectional view of the device disclosing the manner in which the climbing wheel is engaged by the suspended rope, the man-ner in which the climbing wheel is engaged bythe driving wheel, and the ymanner in which the lower end of the suspended rope operates the driving wheel.

Fig. 2 is a side elevation of the device disclosing the arrangement of the climbing wheel, the driving wheel, the ratchet and the band brake. Fig. 3 isa'Vview similar to Fig. 1 but disclosing the 'manner in which the ratchet and the lclimbing wheel vsecured thereto, is released from the pawls and the manner in which the `pawl on the driving wheel engages the .stationary .pawl and op crates the :band brake. Fig. 4 is an enlarged vertical sectional view through the band brake, the climbing wheel, .the ratchet and the driving wheel, disclosing also the spring in the driving wheel by means of which the said driving wheel is Vnormally returned *to a .position where it may rengage the climbf ing wheel. Fig. 5 is a view of the rewind spring.

Referring to the drawings, the numeral 1 is used to designate a 'tubular frame hav,- ing secured thereto an 'open frame 2 within which is rotatably mounted a shaft 3. Rotatably mounted upon the shaft 3 is what I term a driving wheel 4. 'Pivotally mounted upon the said driving wheel 4 is a spring controlled pawl 5 adapted to 'engage a ratchet 6 that is secured to the shaft 3. A second pawl Tis rotatably mounted upon a short shaft *8 secured to the upper Eportion of the open frame 2, said pawl being arranged t0 engage the ratchet 'G on the shaft 3.

At 9, in Figs. 1 and 2 ofthe drawings, the ends of a band brake 10 are secured to the shaft 8 so that when the pawl '7 is released from the ratchet 6, the said shaft oscrllates and causes band brake 10 `to rengage the periphery of the band wheel l'which is secured to the shaft 3. Also secured to the shaft 3 and between the band wheel `12 and the ratchet 6 is a climbing wheel 14. A suspended rope 15 passes over a 'pulley 1'6 rotatably mounted within the `open frarne -2 and after taking a turn around the climbing wheel L14 `passes around a :pulley l?? rotatably mounted upon the lowerle'nd of the-tubular frame 1. Afte'r passingaround fthe pulley 1'7 the rope 15 passes over the pulley 18 which is secured to thei lower eridogfv-a Irope 19 which is secured to fthe periphery of the driving wheel 4. p

The driving wheel 4 is provided with a coil spring 25 one end of which is secured to a pin 22 on `the Iopen fra-me 2 while the other end of the said -sprilng ils secured Eto a pin 23 on the wheel 4. The sp'ring25 l'normally returns the driving wheel y4 t9 the normal position indicated 'in F ig. 1 of the drawings.

The operation is as follows-z By pulling downward o'n the lower end of the rope 15 the said rope in Vturn pulls the pulley 18 the rope 19 downward also, thereby rotating the driving wheel 4 against the tension of the spring 25 and'also .causing the pawl 5 thereon to engage the ratchet .f6 and `rotate lthe shaft 3 and ythe climbing wheel `114 thereon. As `the climbing wheel 14 rotates, the device is carried fupward .lon fthe `suspended rope 15. Before J.the pulley 1:8

reaches the position indicated fin' Fig. 53 `olf the drawings, the lowerend of the'rope 15 is released. -The spring 25 will return the wheel 4 to the normal position shown in Fig.1of the drawings and simultaneously the pawl 7 will engage the ratchet 6 and pre- .vent the said ratchet 6 and the climbing wheel 14 from rotating backward, until the pawl 5 again engages the ratchet 6 when the lower. end of the rope l5 is again pulled downward. The above described operation is repeated until the desired height is attained.

A1n order to lower the device the lower end of the rope 15 isypulled downward until the pulley 18 reaches a position shown in Fig. 3 of the drawings. In this position it will be ,noted that the pawl 5V will disengage the VI claim as new and desire to pawl 7 vfrom the ratchet 6 while the eXtension 5 of the pawl 5 will be engaged by that portion of the pawl 7 on the shaft S which Vwill also cause the pawl 5 to be disengaged .from the ratchet 6.

By pulling downward on the lower end of the rope 15 the wheel 4 will tend to rotate and in so doing will cause the extension 5 ofthe pawl 5 to be engaged by the pawl 7 and to further raise the said pawl 5 and also Ythe pawl 7 which is rigidly secured to the shaft'B. YAs the pawl 7 is raised, it causes the shaft8 topartially rotate and thereby tighten the band brake 10 on the band wheel 12. Byv means of the friction occasioned tivelyconnected to the suspended rope and adapted to engage and partially rotate the climbing wheelfwhenpthe lower end of the suspended rope is pulled downward.
