CLAMP FOR .BOWIBOAT-MOTOBS.
To all lwhom t may concern Beit known that I, WILLIAM F. A. BUEH- NER, residing at Newark, in the county-of Essex andv State of` New Jersey, have invented certain new and useful Improvements inClamps for Rowboat-Motors, of
which the following is a specification.
considerable size at a single throw or turn' of a lever, as distinguished from the two screws heretofore used for this purpose, and to provide means comprised in the clamp retaining it locked in its clamped posltion.
more or less specific than those referred to above, will `be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; .and the scope or protection contemplated will be indicated in the appended claims.
In the accompanying drawings which are to be taken as a partof this specification, and in which I have shown a merely preferred form of embodiment `of the invention: Figure l isa side elevational view of a device constructed in accordance with the principles of this invention;` and Fig. 2 is a front elevational view of the clamp shown in Fig. 1. A
Referring to the drawings for a detailed description of the particularstructure illus-v trated therein, the. reference character Lindicates a frame formed with a pair of spaced so as to accommodate the stern-post of the legs 1 adapted to rest flat against' the-rear surface of the backboard ofthe boat.' Portions, as 2, of this frame are bent outwardly boat.
'In the .drawin s the backboard is illus-lf' trated in dotted vines by the reference numeral 3 and the stern-post by the reference numeral 4.
Specification of Letters Patent.
Other objects and aims of the invention,l
y Patented Nov. 14, 191e.
vApplicationfiled February 15, 1916. Serial No. 78,347. y
At the upper ends of the opposite arms i of the legs' 1 suitable bearing members 5 are 'formed for pivotally connecting the same to the motor and propeller wheel carrying shaft, indicated collectively in dotted linesby the reference numeral 6. Projecting forwardly fromy each of the legs 1, near the upper ends thereof are portions 7, said portions being connected together by a brace member 8 and having their forward ends 'turned downwardly, as at 9. Ther-.downturned portions 9 are each'aperturedto supporta cross shaft 10 about which -is pivotally mounted. a pair of l1 and 12. The clamp member 11 is formed .with an operating handle 13 projecting upclamp members wardly therefrom and being' turned in a direction toward the clamp member 12. The
hand grip 16 is provided upon the part 13."V
itis 'apnA Y By swinging the hand grip 16 parent that the motion thereof will be transmittedequally to leach of the clamp members ll'and 12.
A compression spring 17 is positioned about the shaft 10 intermediate the clamp members 11 and `12 and exerts a pressure serving to .hold the clamp members in resilient engagement with the inner surfaces of the downturned portions 9 of the frame.
The opposing surfaces` of the clamping members of the portionsy 9 of the frame are provided with cooperating teeth 18 thereon encircling' the shaft 10 adapted to retain the clamping members in any position into `which they may beA moved by thehandle grip 16. These lteeth 'preferably are arranged so as to permit. easy travel of the handle grip in one direction but to ,prevent` thereof inthe opposite direct`1on.
movement When it is desired to move the clamping members in the opposite direction they must be manually drawn together lagainst the pressure of the spring 17 and for this purposev the operating handle 14 1s provided with av finger grip 1-9 adjacent the handle grip 16 throughthe medium of which the operator may readily move the clamping members toward each other by grlppmg the handle grip, 16` and finger grip v19 tightly in his hand.
A clamping plate 20 extends across the fullwidth of the frame L and is resiliently supported upon a pair of pins -21 carried at the lower ends of the portions 9. Suitable springs 22 are arranged for lurging the pins backwardly to normally retain the clamping plate 20 out of contact with the surface of the backboard of the boat. n In order that` rotation of the clamp -mem- 'bers 11 will operate to move the clamping plate into engagement with the surface of the backboard of the boat, said clamping members are formed with eccentric .or cam portions 23' shaped so that when the handle grip is in its raised position, as shown by the full lines in Fig. 1, the clamping plate will furthest-removed from the backboard of the boat, and so that-the clamping platewill be moved gradually and forcefully toward' the 'surface -of the'backboard as the i' handle grip is swung downwardly.-
'From the above description it will be apparent that the lower portion of the frame L will serve as one of the clamping members while the clamping plate serves the other. rlhe operator has merely to place the frame in the position lwiththe lower part of the frame L resting .against the rear surface of the backboa-rd of the boat and the forwardly extendingpportions 7 resting upon, or nearly upon the upper edge of the backboard, whereupon he swings l the operating handle downwardly to cam the clamping plate firmly against the backboard,
, the teeth 18' clickingI past each other. The
parts will remain in clamped position until he moves the clamping members to disengage the teeth 18 and allow the operating handle to swing upwardly. 4.
As many changes'could be made in this construction without departing from the scope. of the following claims, it is intended that all matter 'contained in the above description or shown in the accompanying `drawing shall be interpreted as illustrative onlyJand not in a limiting sense.
'Having thus described my invention what I claim` as new and desire to secure by Letters Patentis:
1. A clamp for rowboat motors4 or the like, comprising opposingclamp members,
cam means for operating upon one lof said clamp members at spaced points in the length thereof, and a single 'operating handle for said cam means.
2. A clamp for' rowboat motors or the like, comprising opposing clamp-members, a
pair of cam members spaced apart and operatively' engaging one of said cam members at spaced points in the lehgth of said mentioned clamp member, operating handles formed upon said calm members projecting toward each other, and a single handle grip by means of which both said operating handles may be controlled.
3. A clamp for rowboat motors or the like, comprislng opposing clamp members, a
' pair of cam members spaced apart and operatively engaging one of said clamp members atspacedpoints in the length of said mentioned clamp member, operating handles formed upon'sad cam membersv projecting toward each other, toothed means for retaining the cam members against accidental one' of said clamp members at spaced points upon said mentioned clamp member oper- -able to move said mentioned clamp member into clamping position, and means for moving said operating members in unison.
5. A clamp fort rowboat motors or the like, comprisingv opposing clamp members, resilient means for resiliently urging one of said clam` members away from clamping position, a s aft, aA pair 'of operating members pivotally supported upon said shaft having cam surface portions engaging said mentionedclamp memberat spaced points thereon, control means for rotating said operating members whereby to cause the cam faces thereof to force thel mentioned clamp vmember into clamping position, toothed means for retaining at least one of said operating members ina desired position ofvrotation about the shaft, said operating member being slidable upon the shaft, and resilient means adaptedto permit sliding movement of theoperating member along the shaft to render the toothed means operative.
