MECHANICAL MOV MENT.

Application filed March 28,

T0 mllwhom it concern Be it known that I, ALBERT E, CRANSTON, a citizen of the United States, and aresident of Spokane, in the county of Spokane and State of l Vashington, have invented certain newv and useful Improvements in Mechani-. cal 'Mov'ements, of which the following is a My invention relates to improvements in mechanical movements and has for itsprinc'ipal object to provide a simple and efficient device for converting reciprocating and reversing rotary movement into continuous rotatory movement. I

A further object is to provide a device of the class described which shall employ no ratchets, springs or pawls and thereby .elimi na'te the expense and wear and tear of such elements. p I V,

A further object is to provide a device of theclass described which may be manufac tured cheaply and yet be readily convertible forv a multitude of uses. For example, it may advantageously be used in connection with wrenches or drills as a substitute for the usual ratchets. When used in this man ner there is no idling stroke, but each stroke is a work stroke, hence causing the tool to do twice as much work as would an ordinary ratchet wrench ordrill,

Other objects and features of novelty will. be described in connection with theaccom panying drawings and specifications and more particularly pointed out in and by the appended claims.

In the drawingsre-r a Figure 1 is a side elevation of the improvement I y Figure 2 is a, plan vieiv of the same 7 Figure 3 is an enlarged section on line 33 of Figure 1. I 7

secured thereto pin the which comprises a bevel gear. The. housing 13 encloses gear12 and is provided with a handle 14 which may be'term'ed a holding handle. During the operation of the improvement handle 14 i'sheld stationary and also serves to enable the operator to steady the, device. In the case of a permanent installation handle 14 orthe. housing 1'3 may be rigidly fastened in non-movableposition. 1

Threaded through tl1ehousingf13are th 14 which serve as bearings for bevel %1n1ons 15 which mesh-with; bevel gear, 12;

otatably mounted onshaft 10 is the inter? mediate member 16,.fthe lower surface of which is. cut to. form bevel gear teeth 17 adapted tomeslivvith bevelpinions 15. The upper surface of. member 16 is cut e form engagement teeth 18. The driven mem er s pecification'of Letterslatent, P atefitd M 30,19

1 9 is secured to shaft 10 as by pin20 I provided on'it's lower surfacewith engages ment teeth 21.: In order to keep gear 16 mesh {with pinions 15 9.11am separate momhers 16 and 19 by a predetermined distance,

I have provided the spacing sleeve 22,.Whichmay be either tight or. loose. onshaft 10. In

the present-disclosure I have shown the ends 23 a'nd24 and bearing againstthebottom of counter bores 25 and 26, respectively,-but

it l bwhd f d hat myaofithe usual Y collar means may be substituted for sleeve 22 in order to allow member 16 to revolve on shaft 10 and l i Y pinions 15.. I l

Disposed hetween members 21 16is the driving member 27 which is rotatably and slidably mounted with respect to shaft 10.

on the upper face ofme'mbe 27, are pro? vided the engagement teeth QSregistering with teeth 21 and on the lower side" thereof yet be kept in mesh with are the engagement teeth 29 registering'with I teeth 18. As a convenient means for r0;

tatin'g driving member 27 I have provided 3 the collar 30 secured to member 27 bysuch means as screw 31 and adapted to be ro'.-'

Assuming that the parts he in the position of Figure 2 ml h n e 2 and .lience driv- 7 ing member be rotated in the direction of arrow a or counter cl'o'ckwise, it will be noted ha teeth 21 a 2 are 011F0 61 gag ment- Teeth 2 and 13 be ng i gagement, member 16 will be driven in a nte r l kw se d ecti n 8 d,." filer-9. 8 111 the d um..Q P .lli l 15 will dri e-se r in a cilmkwise diretiba Generate i be driven in a clockwise direction.

" from teeth 18 that a lock would result, but

such is not the case'since the moment faces 0 contact with faces d member 19 will be driven in a clockwise direction (Figure 7) carrying with it the shaft 10 and gear 12, since both member 1.9 and gear 12 are pinned to shaft 10. Gear 12 in-turning clockwise will, through pinions 15, turn intermediate member 16 in a counterclockwise direction and thus aid in thrusting teeth 29 upwardly until they clear teeth 18.

Thus, the shaft 10 is being revolved in a clockwise direction through the direct drive between member27 and member 19, orin the same 7 direction as during the first operation described Upon again changing the direction of rotation of handle 32 and member27. (dotted arrows, Figure 6) teeth28 will back off of teeth 21 and' thereby urge teeth 29 into enga'gement with teeth 18 until the parts are again in the position'of Figure 5 whereupon the continued rotation of, member 27 will revolve shaft 10 in a clockwise direction.

To cause shaft 10 to revolve in a counterclockwise direction, the device may be turnedupside down, handle 32 still being used as a work handle and 14 used as a holding handle. i 1 The ends of shaft 10 may be squared as "at 10 or otherwise mutilated or arranged for the attachment of tools or power transmission devices. v

If handle 32 bejused as a crank connected to a reciprocating rod A as shown in dotted line's Figure 2, it will be seen that reciprocating movement on the part ofrod A will be converted into constant rotary movement on the part of shaft 10.

While I have herein shown and described one specific embodiment of my invention, I

do not wish to be limited thereto eXceptf or such limitations as the claims may impart.
