SCREW-NAIL.
SPECIFICATION formingpart of Letters IPatent No. 736,851, dated August 18, 1903.
Application filed February 6, 1908. Serial No. 142,206- (No model.)
To aZZ whom it may concern.-
Be it known that L'Tnonns BENJAMIN HITCHMAN, a subject of the King of Great Britain and Ireland, and a resident of 41 securing the turned parts of woodwork into their holes or sockets.
In the accompanying drawings, which illustrate this invention, Figures 1, 2, and 3 are views in front elevation, side elevation, and plan, respectively, of my improved nail having a single projection. Figs. 4 and 5 are views in side elevation and plan, respectively, showing a nail havingtwo projections and two shanks. Fig. 6 is a view in elevation, showing a nail with two projections and a single shank. Figs. 7 and 8 are views-showing a further modification, and Fig. 9 is a view showing one application of the invention.
Throughout the views similar parts are marked with like letters of reference.
My improved nail has a flat head a, carrying one or more projections b, shaped and arranged to form and operate as part of a screwthread. The stem 0 of the nail may be of any suitable section,but is preferably made square or rectangular, so as to prevent it turning around inthe part in which it is driven. When the headof the nail carries more than one projection, it may be carried by or have two stems, as shown in Fig. 4. The projections 19 are cone shape in crosssection and are formed with cutting edges- The said projections are preferably placed at such an angle with respect to the head a or the stem 0 as will cause the said projection or projections with the said head or shank, in which case,
however, the nail would require to be driven into the part to which it is to be fixed in such a manner that the projection or projections will when the nail is driven home lie at the necessary angle to form part of a screw-thread on or in the part in which it is fixed.
For ordinary every-dayuse I prefer the construction shown in Figs. 1, 2, and 3, in which the stem is made rectangularin cross-section, so that it will require to be driven into the part to which it is to be fixed with the longest side parallel with the grain of the wood, in which position the projection will lie at the requisite angle to the part to which the nail is fixed to form part of a screw-thread thereon.
Instead of making the article with a plain shank to be fixed as a nail it may be provided with a screwed shank to be fixed as a screw, as shown in Figs. 7 and 8. This screw-nail may be fixed either on the male part of the piece of turned work, as shown by Fig. 9, or in the female part. In either case it forms part of a'screw-thread in the part to which it is fixed, thus enabling the two parts to be firmly and securely fixed together and as readily detached. As the projection has a cutting edge, it easily and readily cuts its own thread in the opposite piece.
This invention is particularly useful for fitting handles to brooms, brushes, and mops, staves to the legs of chairs, and knobs to drawers and other cabinet-work.
It will be obvious that these nails may be made to operate either as right or left handed screws and that they will require a punch having a recess to take the projection or projections to drive them home.
What I claim, and desire to secure by Letters Patent, is
1. In a nail or screw, the combination with the shank, of a head carried by said shank and of a vertically-arranged projection having a cutting edge on said head, as set forth.
2. In a nail, the combination of two shanks, a head carried by said shanks and a vertically-arranged projection having a cutting edge on said head, as set forth.
3. Ina nail, the combination of two shanks a head carried by said shanks, two verticallyarranged projections having cutting edges on said head, as set forth.
