CLAMP FOR OUTBOARD MOTORS Filed Feb. 25 1949 Inventor Carl Williams Patented Feb. 5, 1952 CLAMP FOR OUTBOARD MOTORS Carl Williams, Cornell, Wis.

The present invention relates to new and uselimprovements in clamps for attaching an outardmotor to a boat.

n important object of this invention is to provide a bracket carried by an outboard motor and constructing the bracket to rest on the upper edge of the stern of a boat, together with a lever or handle pivoted to the bracket with its inner end positioned for gripping the stern of the boat to clamp the bracket in position thereon.

Another object of the invention is to provide means for locking the lever or handle in its clamping position.

A still further object is to provide a lever or handle clamping member which may be adjusted in accordance with variations in the width of the stern of the boat to which the bracket is clamped.

A still further object is to provide a device of this character of simple and practical construction, which is strong and durable, eflicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view showing the clamp in position on a boat, and with the latter shown in sections.

Figure 2 is a top plan view of the clamp with the motor removed.

Figure 3 is an enlarged vertical sectional view taken on a line 3-3 of Figure 2, and;

Figure 4 is a vertical transverse sectional view taken on a line 4-4 of Figure 3.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 5 designates a substantially U-shaped inverted bracket for resting on the upper edge of the stem 6 of a boat 1.

One leg of the bracket extends downwardly on the outside of the stem 6, and is formed with a pair of spaced apart aperture ears 9 at the upper portion of leg 8, in which a transverse pin In is positioned for pivotally attaching to the upper portion of a shaft housing H of an outboard motor I2.

The lower end of leg 8 is formed with a pair of spaced parallel upwardly curved arms l3 having an arcuately arranged group of openings 14 wherein to selectively receive a transverse pin Application February 25, 1949, Serial No. 78,334 1 Claim. (01. 248-4) I5 against which the shaft housing of the motor rests to support the motor in a desired position in accordance with variations in the slope of the stern 6 of the boat.

The bracket 5, also includes a pair of spaced apart downwardly extending legs l6 positionedinwardly of the boat and provided with a transverse pin I! for pivotally supporting a handle or lever is positioned between the legs 16.

The handle or lever I8 is of substantially arcuate construction with a hand gri I9 at its. front end and a transversely toothed or corrugated plate 20 secured at its rear end by screws or the like 2 l the plate 20 being positioned for gripping the inner surface of the stern B of the boat.

The upper edge of handle or lever I8 is formed with teeth 22, engaged by the free end of a do 23 positioned between the upper portion of leg I6 and pivoted thereto by a transverse pin 24. A leaf spring 25 is secured to bracket 5 above the dog 23 with the free end of the spring bearing against the dog to hold the same downwardly in engagement with teeth 22. A knob or handle 26 projects upwardly from dog 23' to facilitate the releasing thereof from the teeth 22.

The handle or lever i8 is formed with a plurality of opening 21 for selectively receiving the pivot pin ll, the openings 21 being arranged to adjust the handle or lever I8 on the bracket in accordance with variations in the thickness of the stern 6 of the boat.

In the operation of the device, the bracket 5 is positioned on the upper edge of the stern 6 of a boat and one end of the handle or lever I8 is forced downwardly to cause the clamping plate 20 to bear against the inner surface of stem 6 in a clamping position by the dog 23 engaging teeth 22.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of'the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A clamp for outboard motors comprising an inverted U-shaped bracket adapted to rest on a part of a boat including inner and outer down- 3 wardly extending legs, said outer leg adapted to REFERENCES CITED support a motor, an arcuate lever Pivotany The following references are of record in the nected to the inner leg for swinging into clampme of this patent: ing engagement with said part of the boat, means for adjusting the pivotal connection of said lever 5 UNITED STATES PATENTS on the inner leg for adjusting said lever toward Number Name Date or away from said part of the boat, and pawl 222,086 Slemmier Nov. 25, 1879 and ratchet means for locking said lever in ad- 442,629 Lipscomb Nov. 16, 1890 justed position. 1,467,641 Johnson Sept. 11, 1923
