HENRY E. .GRAHAM AND RICHARD D.- `CHILD, OF BOSTON, MASSA- OHUSETTS. l
Letters Patent No. 97,391, dated November 30, 1869; antedated November 24, 1869.
IMPRovEMz:NT IN COMBINED.. 'WATCH-KEY AND TooTHPIcK The Schedule referred tb in these Letters Patent and making part of the saine.
To all whom it may concern:
A.drawn ont, ready for use.
'Figure 2 is a longitudinal section through Y' the centre of the same, with the toothpick drawn in, and the key ready for use.
fi f. 2.
Our invention consists in a combined Watch-key and toothpick, the latter sliding within the winding-tube of the former, and being provided with a shoulder at its base, corresponding in size and form to theinterior oi' the tube, whichmay'be'instantly freed from dirt collected thereimoby simply pushing out the toothf pick; the tube of thekey serving to protect and keep the tootbpick clean while in the pocket.
lo enable others skilled in the art to understand.
and use our invention, we will proceed to describe/the manner in which we have carried it out.
In the said drawings- A 4is a cylindrical tube or casing, of silver or other suitable material, provided with two longitudinal slots a l), in line with and separated from each other by a portion, c, of' the casing, which serves as a stop for arresting the pins d c which secure the slidlng rings or collars B O, (surrounding the casing A,) to the cylinder-bloclts B' C, (within the casing,) these blocks serving as the basis of two central rods or plungers, 4 5,A whichare readily moved iu contrary dlrectlons vthrough the casing,and through the passages 6 7, formed within its conical-shaped end-pieces or pro- Ve will now describethe construction, operation,4
and oiiice performed by the two rods or plungers 45, commencing with the former (4.)
From h to fi, the rod 4 is oi the form 'of a circle in transverse section; from t to It it is square; andfrom k to ythe point l it is a flattened ellipse, tapering grad- Figure 3 is a transverse section on the line a: :cofl
ually to the point l, and constituting a long, narrow blade, which-serves as atooth'pick, G, the 'blade being of such form that-itv may be moved inand out, without vcoming in contact with the interior oi' the passage 6, formed in the conical -projection D, at one end of the casing.
The form of this passage 6 is square in transverse section, and ,of a size corresponding to the square portion t k of the rod or plunger 4, and is intended as a key, H, for winding a watelnthe square portion t' k, of the rod4when,tl i e toothpick is pushed ont, serving to clear the tube of the key from dirt or foreign matter which may collect therein when carried in the pocket. A
As the blade of the toothpick, when pushed in and out, doesl not touch the inside ofthe tube, no liability l of rustrbeing formed therein by the. moisture ofi the toothpick will occur, while the tube ofthe key serves to inclose and protect the pickwhen in the pocket.
The rod 5 is of' a circular form', and`is intended as a plunger for pushing out, and retaining in its proper place, a circular lead, 8, within the projection E, so that if desired, a lead pencil can vbe combined, in a convenient form, with the watch-key and toothpick, but the mechanism belonging to the lead pencil may be omitted,vif desired, without departing from'the spirit of our invention.
XVe are aware that a combined .watch-key and toothpick are not new, and we are also aware that watchkeys have been made, containing a plunger for the purpose of removing dirt, &c. These inventions we do'not claim; but
What we claim as our invention, and desire to secure by Letters'Patent, is-
l; A combined'watch-key, H, and toothpick G, when the latter slides within the winding-tube of the former, substantially, as and for the purpose setvforth. i
2. Also .the projection E, for containing a pencil,
combined with the watch-key H and toothpick G,
when they are formed as above described.
