To all whom it may concern: 1

Beit known, that I, FENTON ToiuLmsoN, citizen of the United States, residing at San Diego, in the county of'San Diego and State of California, have. invented certain new and useful Improvements in Driving and Releasing Mechanism, of which the followin is a specification.

y invention relates to mechanical move- 10 ments and particularly to means for driving a driven element from a driving-element and at will releasing the driven element from the driving element.

a "simple andreliable rotary driving mecha- A further object is to provide means.

whereby the forces acting on the driving element to get reverse motion can either be applied dlrectly to the driving element 'or' ap lied directly to the'driven element. y mechanical movement is shown in the accompanying drawings, itbeing understood that the movement may beapplied-to .a large variety of mechanism.

driven element of said m'echanism from a a driving element.

In the embodiment of my invention which is illustrated in the drawings, 2 designates a central" shaft which is supported in any suitable manner and which is surrounded .by'a, tubular rotatable shaft 3 which forms --the driving shaft, this rotatable shaft 3 being driven in any suitable manner and being provided with the rotatable driving element 4:, which in the illustration of my invention has the form of a'disk. It is to be. understood that while I have shown the-disk 4 as being mo'untedupon and driven with the tubular shaft 3, the disk 4 might be driven in any suitable manner and rest directly upon the shaft 2. Located immedi- 7o ately ad acent to the disk 4, as for instance upon the shaft 2, is a rotatable driven element 5 which in this embodiment of my invention has'the form of a disk, which disk is provided upon its circumference with ratchet teeth 6; 1

- Located immediately adjacent tothe disk '5 and in fixed relation to the driving and driven members 4 and 5, is a fixed element 7 also having the form of a disk. and shown as mounted upon the shaft 2 but non-rotatable therewith. In the illustration I this disk 'I is sup orted by means of a bracket 8 which exten s upward from a base 9 supi ported in any suitable manner. I'do not wish to limit myself, however, to any particular means for supporting the disk 7 fixedly with relation to the driving and.

driven elements.

ing element 4 to t e driven-element 5, I mount uplon the inner face of the driving element t e pawl 10. This is pivoted at its outer end as at 11 adjacent to the circumference of the disk and it's free end is angularly bent and adapted toengage with the p ratchet teeth 6. A spring 12'may be used to forcethe free .end of the pawl 10 into engagement with the ratchet teeth 6 and a stop 13 may be used to limit the outward movement of the pawl. I do not, however,

wish to limit myself to these features. Pivotally mounted upon the pawl 10 is u,

pawl14 which is oppositely directed with relation to the pawl 10 and'which "ngages with relatively short ratch-et teeth 15 formed he unnecessary wear and jar. By using the catch 29, the pawl is held out of engagement when once thrown. The catch may he tripped with the finger, 21 will return to its usual position.

What I claim is: d

In a mechanical movement of the character described a rotatable driving element, a rotatable driven element being formed with ratchet teeth a pawl on the driving element engaging "with said ratchet teeth, a spring; holding the pawl in engagement with the ratchet teeth, a non-rotatable element mounted concentric to the vent-er oi. rotation of said driven and driving element-sand formed with periph eral. ratchet teeth i'evei'se to the ratchet. teeth on the driven element, a pawl carried by the first named pawl and acting in a re verse direction thereto and engaging the teeth of the noniotatahle element, said non-rotatable elementbeing longitndinzdly shiit'tahle with relation to the driven. ele- HIQHi' In a mechanical movement, aH'ot-atahle driving element, a rotatable driven element, both moving about a common center the driven element being formed With ratchet teetln a pawl carried by the driving element and engaging the teeth of the driven element, a spring holding; the pawl in positive engagement with said teeth, a. non-rotatable ratcheted member coneentric in said oonnnon center and having ratchet teeth re- (Lopies of this patent-may be obtained for whereupon the pawl element, the diiven I g;- reetion thereto, the ex i'enn het teeth on the *rse dil pawl of en i ratcheted member, a casing ing, and a resilient detentiirst named pawl and pi'oj opening said detent being having an openattached to said ecting into said formed wiuh a head adant-ed t0 en a e over the wall of i i b said opening when the first named pawl 18 elei'nen't while the driving ing in one direction, means reverse movement of the ment, a. driving means for conwith the driven element is niovoperated by a driving element for disconnectingsaid connecting means, a
