shank at is first affixed to the grip Z), or, if desired, these parts may be made entirely of metal and in a single casting. The clawplate Z) is then attached to the shank a, preferably by rivets, the shoulder 6 serving as a guide to regulate the adjustment of this plate,and thereafter by preventing movement thereof, either vertical or rotary, to prevent a shearing strain on the bolts and an instability while in use.
The operation of the tack-claw is substantially the same whether it is used in drawing aheaded tack, as shown in Fig. 3, or adoublepointed tack, as shown in Fig. 4. In either case the fulcrum cl and claws jj are simultaneously brought to bear upon the flooring or the covering therefor close to the head or cross-head of the tack, and the thin edge of the said claws is inserted beneath the same and forced thereunder, the slight wedging effect produced by the pitch of inclination of the side g serving merely to start the tack sufficiently to insure a firm grip thereon by the claws. The lever handle A is then pressed downward, oscillating upon the fulcrum d. The initial movement of the claws 7' 7" is insufiiciently diverted from the vertical to bend the tack, and as the lcver-handle descends the rolling fulcrum f contacts with the floor, and subsequent movement is with this as a center. This varies the leverage to an extent to ease up the latter portion of the operation and also has a tendency to thrust the claw forward sufficiently to compensate for the slight rotary movement of the said claws. Hence the movement of the claws will be substantially vertical throughout the operation. WVhen the claw is tf'sed to draw the ordinary headed tack, the point passes into the slot 2' and the claws j j engage the WVhen the claw is used to draw a double-pointed tack, both clawsjj pass directly beneath the cross-head whichthey engage. In either case the mode of operation of the claw will be seen to be substantially the same.
It will be observed that by reason of the horizontal surface presented b 1 the beveled portion 72. and the horizontal alinement of this surface with the bearing-face of the fulcrum d the depression of the claws to admit of the insertion thereof beneath the tack does not result in the presentation downwardly of a sharp edge against the flooring, carpet, or matting and that therefore the tack-claw cannot out these in Withdrawin g tacks therefrom. It will also be observed that the adaptability of the claw to use for both headed and donble-pointed tacks, as above described, is accomplished without rendering the device on mbersome or sacrificing its appearance or strength, sufficient metal being employed at those points where the greatest strains occur to withstand such.
It is not myintention to limit the invention to the precise details of construction heretofore described, as it is apparent that these details may be varied without departing from the spirit and scope of the invention.
Having described the invention, what I claim as new, and desire to have protected by Letters Patent, is-
1. As a new article of manufacture, a tackclaw comprising a lever-handle having a downwardly-projected fulcrum at its lower end and a claw-plate consisting of an angular plate the sides of which are respectively secured to said handle and projected downwardly and forwardly, said last-mentioned side being laterally reduced toward its outer end and slotted-centrally of this reduced portion and beveled on the under side thereof on substantially the same plane as the bearing-face of said fulcrum.
2. As a new article of manufacture, a tack claw comprising a leverhandle having a downwardly-projected fulcrum at its lower end and a rolling fulcrum above said firstmentioned fulcrum, and a claw-plate consisting of an angular plate the sides of which respectively are secured to said lever-handle and projected downwardly and forwardly, said last-mentioned side being laterally reduced toward its outer end and slotted centrally of this reduced portion and beveled on the under side thereof on substantially the same plane as the bearing-face of said fulcrum.
3. As a new article of manufacture, a tackclaw comprising a leverhandle having a transverse shoulder near its lower end, a downwardly-projected fulcrum at its lower end, a rolling fulcrum above said first-mentioned fulcrum, and a claw-plate consisting of an angular plate, the sides of which respectively are secured to said lever-handle adjacent to said shoulder, and projected downwardly and forwardly, said last-mentioi1ed side being laterally reduced toward its outer end and slotted centrally of this reduced portion and beveled on the under side thereof on substantially the same plane as the bearingface of said first-mentioned fulcrum.
In witness whereof I have hereunto affixed my signature, this 25th day of February, 1903, in the presence of two witnesses.
