' acteri herein described which will prevent, the
surface, of the work to which such clamps are attachedfrom becoming scratched, deformed, or otherwise damaged; j
A further object of the invention is to provide a cushioning device, which, by virtue of its protective nature, is particularly adapted for use with the mounting brackets of outboard motors.
Another object is to provide a cushioning device which is simple in construction and which may be readily attached to the clamp with which it is employed. a
An additional object of the invention is to provide cushioning device which will readily lend itself to economical manufacture.
With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:
Figure 1 is a side elevation of an outboard motor mounting bracket, showing the invention in situ thereon.
Figure 2 is a cross-sectional view, taken sub-- stantially in the plane of the line 22 of Fig- .ure 1.
Figure 3 is an elevational view of a modified embodiment of the invention, the same being used in association with a conventional clamp, and
Figure 4 is a cross-sectional view, taken substantially in the plane of the line 4li in Figure 3.
1 Claim. (@l. 144-304) ary jaw of the mounting bracket, the movable jaws, so to speak, assuming the form of one or more clamping heads I4 rotatably mounted on a corresponding number of clamping screws i, the latter in turn, being positioned .in suitable extension or extensions l6 of the aforementioned web II.
The structure heretofore described is, of course, of a conventional character and the essence of the invention resides in the provision. of a cushioning device consisting of the pads I! and I8.
These pads are formed from any suitable material possessing resilient characteristics, such as synthetic rubber, Neoprene, or the like, and the pad I! is positioned adjacent the motor board engaging surfaces l3 of the stationary jaw l2, as will be clearly apparent from the accompanying drawings.
The cross-sectional configuration of the pad I! is best illustrated in the accompanying Figure 2, wherein it will be apparent that the pad is formed with channel-like retaining flanges l9, these being adapted to engage the marginal edge portions of the aforementioned flange l2, whereby the pad may be effectively retained in position.
Similarly, the pad 18 is positioned on the movable jaw or clamping head I4, suitable retaining flanges 20 also being provided on this pad, for obvious reasons.
When the invention is placed in use, the pads I1 and 3 will, of course, contact the surfaces of the motor mounting board on which the bracket I0 is positioned, whereby said surfaces will be effectively protected from scratching and other previously experienced injuries.
Referring now to the accompanying Figures 3 and 4, the clamp designated by the reference character 25 represents a device of conventional design, such as is commonly employed by carpenters, or the like, for holding together two pieces of wood during fabrication.
A modified embodiment of the invention may be employed with satisfactory results in this connection, the same assuming the form of a'pair of resilient pads 26 secured by adhesive to the opposed faces 2'! of the clamping jaws '28.
It should be noted that the pads 26 may, if desired, be provided with retaining flanges similar to the aforementioned flanges l9 and 20, to facilitate the retention thereof upon the jaws 28. Conversely, the flanges l9 and 2e may be dispensed with in the aforementioned pads I1 and 18 respectively, and the latter may be secured to the respective jaws l2 and I4 by means of suitable adhesive.
It should be also understood that while only two modified embodiments of the invention are shown in the accompanying drawings, the application thereof may be extended to clamps and clamping brackets of various types, the particular configuration of the resilient pads employed being, of course dependent upon the nature and configuration of the particular clamp with which the invention is used.
It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure, and accordingly, further description thereof at this point is considered unnecessary.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
What I claim as my invention is:
Cushioning means for a C-type mounting brackethaving a web portion, a major leg portion, a minor leg portion, an adjustable clamping screw carried by the minor leg portion for positioning relative to the major leg portion, and flange strips integrally formed with the major leg portion and web portion of the bracket; said cushioning means comprising a readily removable and replaceable substantially L-shaped pad of resilient material including a shorter leg for frictionally engaging the flange strip of the web portion of the bracket, a longer leg C-shaped in cross section for yieldingly embracing the flange strip of the major leg of the bracket, the shorter leg of said pad being also C-shaped in cross section for yieldably embracing the web portion of the bracket, and a readily removable and replaceable companion resilient pad, circular in outline and C-shaped in cross section, carried by the adjustable clamping screw and opposing said longer leg of said L-shaped pad on the major leg of the bracket.
