' NAIL R.
SPECIFICATION forming part of Letters Patent No. 498,664, dated May 30, 1893.
Application filed November 25, 1892. Serial No. 453,060. (No model.)
' Be it known that I, JOHN E. LEATHERS,a citizen of the United States, residing at Peterborough, in the county ofllillsborough and State of New Hampshire, have invented a new and useful Nail or Staple, of which the fola lowing is a specification.
This invention relates to improvements in driven fasteners, such as nails,-staples, &c.;,
and it has for its object to provide certain Improvements in shanked or pronged fasteners, such as nails, spikes, staples,'tacks and the like, which shallrenderthe same more eflctive in the uses to be adapted.
To this end the invention primarily contemplates a nail, spike, 850., having improved which the same may means for driving, drawing and securing the.
' j same in the object, in connection'with which staple.
the same may be used. I
With these and other objects in View which will readily appear as the nature-of the in vention is better understood the same consists in the novel construction, combinationand arrangement of parts, hereinafter more fully illustrated, described and claimed. In the accompanying drawings:Figure l is a front view of a nail constructed in ac- Fig. 2 is an edge or side view of the same. Fig. 3' is a front elevation of a staple provided with the improvements contemplated by this invention. Fig. 4 is an edge or side vie'wof the Referring to the accompanying drawings:' A represents a shank of a nail which is tapered toward its pointed end toform the usual'opposite flattened faces a, and the shan k A terminates at its upper end in the heads B and C, respectively, the'latter of which serves 7 in the capacity of an auxiliary head for the purpose of driving and withdrawing the nail when used for fastening temporarily or permanently. The head G, is of approximately the same diameter as the rounded head B,
' and meets the latter head at its base in aneck D, which readily receives the claw of a. hammer or device for withdrawing the nail. Now it will be readily seen that the nail can be driven into any object up to the inner head B, as usual, to secure the meet the entire or wedge shaped projectionsE. I angular or wedge shaped p rojectionsE,--project out from the opposite faces of thenail is exposed, so that the nail can be withdrawn when so desired, and it will alsobe apparent that for perm anent work thenail can bedriven entirely homeso that the upper auxiliary head C, can alsobe put into the. object flush with vided upon each of the opposite flattened shank A, While at the same time the head 0,
faces a, thereof, with the opposite triangular and serve as wedges to secure the same in p0 The said tri sition in the object into which the'same may be driven.
and have their apices G, extend centrally up The. projections .E, have "their .bases F, terminate flush with thepoint of-the shank- A, and of a width equaling the point,
the faces on the shank toward'the'heads, so I as to form combined stopand cutting edges.
The projections E, form wedges around which thewood settles as the nail is driven into po-' sition, so thatv there is no dangerwhatever of the nail flying out when used in'hard woods or frost bitten wood, and .also prevents the Y the apicesG, form stops which tendto prevent the withdrawal of the nail, the same also serve as cutting edges, so that the wedges can being withdrawn.
seen that the same would be. particularly adapted for splitting pnrposes,1inasmuch as thenail will not fly out'of position while be ing driven. V
' nail from becoming loose in the wood. While As illustrated in Figs. 3 and 4, the constructions herein described are applied, to a staple H. The staple H, is provided withthe usual parallel prongs or shanks I, upon the opposite flat faces of which are the triangular or wedge shaped projections E, similar in detail to the projections E, and serving the self-same function, while the staple is also provided with the head 0, at the, base of which is, formed the neckD', so that the staple shall have the same adaptation for driving andwithdrawing as the nail described, and may be used for various purposes, 'Itwill of course be understood that the nail and stapleconstructions are adapted to all driven fasteners such as spikes, tacks, and the like.
From the foregoing description it is thought that the construction, operation and many advantages of the herein described improvement will be apparent.
Having thus described my invention, what.
- I claim, and desire to secure by Letters Patent, is
In a driven fastener for wood, the driving shank having opposite flattened faces leading to its point and opposite triangular wedgeshaped projections projecting out from said opposite flattened faces and having their bases the presence of two witnesses.
