3 Claims. 1

This invention relates to a handle structure and particularly to a handle structure used with a flexible member which is to be pulled upon. One important application of the invention is that for the handle on the starter of an outboard motor. Such starting devices now commonly comprise a flexible member or cap to one end of which a handle is secured for pulling upon the cable.

It is an object of this invention to provide a simple and efficient handle structure and one which is closed.

It is a further object of the invention to provide a handle structure adapted to be used with a flexible member comprising a member adapted to be grasped in the hand, and preferably of knob-like structure, said member having a chamber therein open at one side of said member and having a passage extending from said chamber to the opposite side of said member, a flexible member extending through said passage and having an enlarged means, such as a knot, at its end disposed in said chamber, together with means for closing the open side of said chamber and concealing said enlarged means.

It is more specifically an object of the invention to provide a handle structure comprising a member of yielding or resilient material and formed so as to be grasped in the hand, said member having a chamber therein open at one side of said member and having a passage of much less transverse dimension than said chamber extending from said chamber to the opposite side of said member, a disc disposed in said chamber at th side thereof adjacent said passage and having an aperture therethrough alined with said passage, a flexible member extending through said passage and aperture and having an enlarged means, such as a knot, at its end disposed in said chamber and abutting said disc, said first mentioned member having an annular groove extending about said chamber adjacent said open side, and a cap having an outwardly extending annular flange adapted to be sprung into said groove for closing said open side.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which- Fig. 1 is a plan view showing a portion of an outboard motor;

Fig. 2 is a central vertical section;

Fig. 3 is a central vertical section of one member used; and

Fig. 4 is a view in side elevation of a cap used.

Referring to the drawings, a portion II] of an outboard motor housing or casing is shown in which the mechanism of a starter device is contained. Said casing has a boss Illa formed thereon which is apertured to provide a passage for a flexible member, such as a cable I I. A handle member I2 is provided adapted to be grasped in the hand and while this might take various forms, in the embodiment of the invention illustrated it is shown as in the form of a knob having a rear reduced cylindrical portion I2a which has a short tapering portion I 2b adapted to seat in a recess in lug Illa. While member I2 could be mad of various material, it preferably is made of some yielding or resilient material, such as rubber or a rubber composition. Member i2 is provided with a chamber I20 shown as of general cylin drical form, and said chamber is open at one side of member l2, which is the outer or front side. A passage I2d extends from chamber I2c to the opposite side of member I2, which passage is of much less transverse dimension than chamber I2c so that a shoulder I2e is formed at the rear side of said chamber. The flexible member II, which is usually in the form of a rope or cable, extends through passage I2d and has a terminal portion Ila having an enlarged means thereon which can conveniently be a knot. The enlarged portion or knot Ila is adapted to abut against a disc I3 disposed at the rear side of chamber I20 and having a flange extending thereabout so that the same is of cup-shaped form. Disc I3 has a central aperture through which member II extends, said aperture being alined with passage I 2d and the enlarged means or knot Ila abuts against member I3. Withdrawal of member II through passage l2d is thus prevented. Member I2 is provided adjacent the open side of chamber I20 with an annular groove I2 which extends about said chamber. A closed rounded cap I 4 has an outwardly extending flange Ma and flange Ma is adapted to be sprung into groove I2) to secure cap I4 to member I2.

In the use of the device, cable I I will be attached to the proper member of the starting device and will be passed through lug Ilia. Said cable can then be passed through passage I2d in member I 2, member I3 having previously been placed in position in member I2. The enlarged means or knot IIa can now be formed or placed on member II and the same disposed in chamber I2c against disc I3. The member II is usually resiliently pulled into the housing I0 so that the knot Ila will be pulled against disc I3 and the handle member I2 will be held in position against lug Illa. The cap M can now be placed in position by springing flange Ma into the groove 12 Member 12 will yield sufficiently for this placement. Cap I4 is now securely held in position and the open side of chamber 120 is closed and the terminal end and enlargement on cable I! is covered or concealed. In starting the motor, handle HZis pulled upon, which pulls upon cable ii and handle 12 is then released. The enlarged means or knot Ha of course prevents cable Ii from being pulled out through passage i203.

From the above description it will be seen that I have provided a simple and efficient structure of handle. The cable H is efiiciently disposed and can be pulled upon as desired. The cap [4 closes the opening at one side of handle 12 so that dirt or water is excluded. The end of cable I! with the enlargement thereon is also protected from dirt, water, oil or grease. A very compact and efficient structure is thus produced. The member 12 is preferably made of rubber or rubber-like material so that it is Waterproof and does not readily absorb any grease or dirt. device has been amply demonstrated in actual practice, found to be very successful and efiicient and is being commercially made.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.

What is claimed is:

l. A handle structure for the pull cord of an outboard motor having in combination, a member made of rubber and comprising a substantially knoblike front end with a substantially cylindrical shank at its rear end, said member having a passage extending axially therethrough, said passage having a greatly enlarged cylindrical portion at its front end opening at said front end and forming a shoulder at its inner end, said member having an annular groove in the wall of said enlarged portion of said passage adjacent its front end, a cord extending through said passage and having a knot disposed in said enlarged portion and adapted to engage said shoulder and a substantially cylindrical metal cap having a projecting annular terminal flange adapted to be disposed in said groove by de- REFERENCES CITED The following references are of record in the file of this patent:
