Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed January 11, 1911. Serial; No. 602,076.

To all'whom z't-may concern:

Be it known that we, \VINFIELD HANCOCK Yos'r, a citizen of the United States, and GEononBrsE'r Donnr, a subject of the King of Great Britain; both residentsof the city of Montreal, in the Province of Quebec, Dominion of Canada, have invented certain new and useful Improvementsin Devices for Imparting Motion; an'd'we do hereby declare that the following is a full, clear; and eiiact 'description of the same.

Our inventionrelates to operating mechanism of thetype in which operation of amovable' part is elfected by an oscillatory or reciprocatory device adapted to alternately engage with and disengage therefrom; andfurther tdmanually operated devices of the above type in which the manually operated member is adapted to remainout-of opera: tive relation with and adjacent to the said part when the device is not in operation. The invention has for its object to providean improved device of this kind which will be more simple in construction and easily operated than those heretofore-lmown, and in which the parts wil-lnot be liable to get outof order when the device is in use.

I Uther objects and advantagesof theinvention will be apparent to those skilled in the art from a consideration of the follow-- ing description and accompanying drawings in which one form of construction embody-1 ing the invention has been described and illustrated and iirwhich similar reference characters. indicate the sameparts;

Referring'now to the drawings 1' Figurel' is a plan view ofithe device in use; Fig.2 is a side eleva'tion thereof and Fig. .3: is an enlarged plan viewofa portion of the device; the-operating member being shown in section;

In the embodiment of 'our invention here-- in: illustrated the-partto be moved com prises vertical shaft 6 forming the brake" mast of a car, a corner post and topp-la-teofthe 'car being shown-at 0- a'nd drespecti vely;

this shaft h aving. fixed thereon a device adapted to be'en'gaged and movedby the operating mechanism; the device thus form ing-- part of'the'shaftgor other part to be moved or rotated.

to the shaft as at e and further secured This---,devi ce isprefer: j ably in the form of a ratchet wheel ekeyed engage and release the said device upon 7 operation of the lever, this member as here shown being-inthe form of a-pawl 5/ adapted to'engage the teeth of the ratchet wheel 6'.

The lever f with the pawl g is in the present embodiment of our invent-ion carried upon abracket arm or carrier revoluble concentrically with the ratchet wheel, this carrier as-hereshownbeing. formed by a two piece strap. h loosely encircling an elongation of the hubi of the ratchet wheel and having upwardly extending ends j, a. flange Z on thehub z preventing longitudinal dis,- placement of the carrier while the twoparts of the strap are held in position by a hook and slot connection m and a bolt n or other suitable means. The lever f is connectedto opposite-sides of the other as shown in Fig.

3', the lever'having formedon opposite sides thereof; a. pair of oppositelyfacing .lugs f adapted,=asshown inFiglB, to bear against the ends ofth'e carrier when the leveris in engagement withthe ratchet wheel in order to preventundueistrainon the bolt It. By meansof this; connection the lever f has limited movement relativelyto the carrier,

the limiting of this movement being. effected by'the parallel sides of the opening. engag ing the 'bolt} h and the lugs j bearing upon theendsj of thecarri'er. It'willthus-be I seen-thatthe lever and carrier together formv a. j ointe'dlever the relative movement of the parts. of which causes the lever to engage with and disengage from the ratchet wheel upon operation thereof.

Elieabo e.d s ribeasqne e ie a s ir "wheel. It will be also noted that this con struction provides a direct connection between the lever and carrier permitting of movement of the lever in planes at right angles to each other. The upper side of the engaging 8110. of the pawl-c is preferably provided with a forwardly extending flange 9 adapted to bear against the top of the ratchetwheel and limit the upward swing of the handle past its proper operative position which is shown particularly in Fig. 2.

The shaft may be located against reverse rotation by any suitable means as the weighted pawl p mounted on a bracket 9" bolted to the corner post 0, this pawl engaging a second ratchet wheel s, fixed upon the shaft 12, and being held yieldingly in engagement with the ratchet wheel by a weight 5' pivoted on the bracket rand normally resting on the tail r of the pawl.

When the device is not in use the operating handle f hangs in the position shown in dotted lines in Fig. 2. When it is desired to rotate the shaft this handle or lever is swung to the position shown in full lines in Fig. 2, in which position the pawl is in operative relation with the ratchet wheel with which it is then engaged by a slight forward horizontal movement of the handle, the further movement of the handle in the same direction causing the ratchet wheel and with it the shaft to be rotated as will be readily understood, while upon the reverse movement of the handle the pawl will be withi drawn from engagement with the ratchet wheel, and the lever and the revoluble bracket will swing backward together, the pawl g automatically rengaging the ratchet wheel when the lever is again moved forward. When the operating handle is released it will fall by its own weight to the position shown in dotted lines in Fig. 2 with the pawl removed from operative relation with the ratchet wheel.

lVhat we claim is as follows:

1. The combination with a part to be 7 moved, of operating means including a bodily movable carrier and a lever fulcrumed upon the said carrier to move relatively thereto parallel to the plane of movement thereof, and adapted to engage the said part, and move said carrier and part in unison, and means carried by the said carrier and lever for limiting the said relative movement thereof upon movement of 3,Tl1e combination with a part 'to'be moved, of operating means including a jointed reciprocatory lever, the parts where- 1. V of have relative movement in the plane of operative reciprocation of the lever whereby the lever is caused to engage with or dis-f engage from the part to be operated, and

means independent of the part to be moved for limiting the said relative movement of the lever parts upon being moved to a position to cause the lever to engage the said" part to be moved, for the purpose set forth.

a. The combination with a part to be rotated, of an arm pivoted atone end concentrically to such part, a lever adapted to engage and rotate such part and means pro-- viding a gimbal-joint connection between the lever and the other end of said arm whereby the lever may be swung in one dd:

rection relatively to saidt arm and also in 11 another direction relatively to such arm and at right angles to the first direction.

5. The combination with a part to be. moved, of an arm pivoted at one endconcentrically to such part and a lever adapted to engage and rotate such part, the lever being pivoted to the opposite end of the arm and having two swinging movements independently of the latter and in two dis tinct directions with relation to such arm.

6. The combination with a part to be moved, of an arm pivoted at one end concentrically to such part,a lever'adapted to rotate said part and presenting a "fiaredf opening and a pivot pin carrled by theiarm and located in said flared opening.

7. The combination with a'shaft, of. a

carrier and a lever supported by' said carrier, such lever having a swinglng movement transversely of the'shaft and independently of the carrier and a swinging movement 1n the longitudinal line of the shaft'and in- I dependently of the carrier.

8. The combination with a shaft,ot

carrier and alever' supported by said car ri'er, such lever having horizontal swing-- ing movement independently of the carrier and a vertical swinging movement inde-: pendently of the carrier. i

9. The combination with a part tolbe moved, of operating means, including a jointed lever, one of the partswhereof is 1 formed with a transverse opening enlarging from the center toward the ends, and

means connecting such parts through the said opening.

10. The combination with a part to be moved, of operating means, including a jointed lever, one of the parts whereof is formed with a transverse opening enlarging from the center toward the ends to form oppositely flared portions the sides of each of which are parallel to the opposite sides of the other, and means connecting such parts together, including amember carried by the other part and passing through the said opening. 7

11. The combination with a rotatable part, of an arm pivoted concentrically thereto at one end and a reciprocating lever connected to the other end of the arm by a gimbal-joint connection whereby the lever may be swung in one direction relatively to said arm and also in another direction rela tively to such arm and at right angles to the first direction, such lever having a member thereon adapted, when thelever is swung, to engage and rotate said rotatable part, the member having a flange extension adapted to bear against said part to be rotated and limit the movement of the lever with respect thereto in a direction vertical to its plane of operative reciprocation.

12. The combination with a part to b together moved, of operating means, including a jointed lever one of the parts whereof is formed with a transverse opening enlarging from the center toward the'ends, and means connecting such parts together, including a bolt carried by the other part and extending through the said opening.

13. The combination with a part to be moved, of operating means including a jointed lever one of the parts whereof is formed with a transverse opening, and means connecting the said parts together, including a bolt passing through the said opening in a direction common to the plane of operative movement of the lever and carried by the other part, the ends of the opening being of substantially greater dimensions than the adjacent parts of the bolt.

14:. The combination with a part to be moved, of operating means comprising a jointed lever, the parts whereof have relative movement in the plane of operation of the lever, and means for limiting such movement, in one direction including a pair oflugs formed on one lever part on diametrically opposite sides of the point of connection of the lever parts and adapted to bear against the other lever part.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
