LYMAN 1R. BLAKE, 0F BrRQQ-KLYN, NEW YORK.
f'specicationfforming part `of lLetters'I-atent-No. l43g322fdatedi-September 30, 1873 papplication filed .'Septeinber`3,'1873.
To all whom it may concern:
EBe -it known that I, .LLYMAN TR. `BLAKE, of
fBrooklyn, .in the :countyof Kings and l State of New York, ihave invented an .Improved Lasting Mechanism; and I do hereby declarethat .the following, taken in connection with :the-
drawings `.which accompany and form epart :of
.this specicatiomis a description of .myzinven-V tion sufficient to enable those skilled in the art toepractice'it.
United :States `:Letters Patent No. 90, 650,
,dated `June Il, 1869, were granted :to W.
Fischer for aan v:improved lasting-tool, which Letters Patenthavebeen reissued, the reissue being. datedJ J ulyi1,'187 3,V and4 covering a combljke nail-blank, and` atool designed lto cut nails one by one from a comb-like blank, and to drive' each-.nail bythe blow that cutsit.
My presentinvention relates Ito :a blank and altool-embodying,.to.a greater or less extent,"
y the invention shown in such Fischer-patent,n
end, I make the blank with a head or flange,
formed by simply bending one edge of the nailplate to a right-angular position to the toothforming portion thereof, thereby securing a head for the nail (which, in practice, it must have, to be of much value) without upsetting the metal, as is shown in the patent No. 131,080, granted to ine September 3, 1872. Not only does the blank thus formed make a better nail than the Fischer nail, and a simpler nail than the Blake nail, (as made oin the specific blanks shown in the said patents,) but it also enables me to separate each nail in turn eom the blank and drive it with greater certainty than by the other constructions, a peculiar construction of my driving-tool designed for the peculiar construction of my blank insuring this result. For this purpose I form the tool with a roadway or guideway for the blank, standing at an angle to the. axial driver-tube, the head or top part of said roadway being in line with the axis of the driver-tube and the toothpassage, inclining therefrom. When the end of the blank passes under the driver the inclined tooth or nail shank at such end stands in front of a bender, which is driven forward :asthe f driver descends,:and bends ltheshank tovertical, orV approximately vertical, position, Vsothatit not 'only stands vaway from the rest 4of the blank-teeth, but-is `in such position un` -dertheidriver lthat the descent-ofl the driver :seversthezhead, and'drivesfthe nail vertically into the :surface 1 against which the nose of the vftoolzis held, the absence of a head on one side Lof Vtheznail-,enablingit to 4glide by the-endof the bender, which =acts asa guide until the `severed nail has passed `by it. `My invention consists, primarily, ini the i construction of the `:nail-severing anddriving tool `to thus bend,
.and sever, and drive theI nail, and in the blank made with aIbenthead-forming iian ge.
v`The drawing represents the tool and blank embodying my invention.'
Figure'll shows the Stool in front elevation. Fig. 2 isa sideA elevation-of it. Fig. 3 is a sectional-elevation. fvFig. 4fshows-the position of theibenderfand driver just after the nail-shank .hasbeen bent.
a denotes the main tube, containing the sliding piston b, from which extends the driver c. The piston is raised by a spring, d, and driven down by a blow upon the cap e. In normalV position, the foot of the driver stands in or just above the top of a nail-tube, f, and into one side of this tube extends the lateral passage g, through which the nail-blank is fed.
The top part h of this passage opens directly into the nail-tube beneath the driver, but the other part c' extends back therefrom, opening into a space or chamber, k, and in front of an inclined bender, l, at the foot of a lever, on. rEhe blank, as shown in Figs. 1, 2, 3, and 4, and also as shown in the special Figs. 5, 6, and 7, is made from a plate of uniform thickness, having one edge bent over to form a flange or head, n, the part below this flange being cut out to form the teeth or nail-Shanks o. There is therefore a head projection only on one side of the plate, the shape of each nail being an inverted L, the head being readily formed by a simple bending or Hanging operation. The blank-passage or guideway is correspondingly shaped to receive this formation, and the plates p, in or by which the blank-passage is made, are inclined, as seen in Fig. 1. The end of the blank being thrust into the outer end of the passage g, passes by afeed-pawl, q, jointed to alever,
r', and pressed against the blank by a suitable spring. The pawl end of the lever is pressed back normally by the action of a spring, s, and is pressed forward to feed the blank by a projection or shoulder on the piston b, which acts against the upper arm of the lever (to press it back and the lower arm inward) as the piston rises. The blank is thereby fed forward the Width of one nail at each rise of the piston, and the pawl is moved back to normal position by the springs as the piston descends. The blank is held in position as the feed-pawl moves back by a detainer-pawl or spring, u, vplaced between the plates p and fastened at c, the front end of the spring being bent, and extending between the teeth of the blank, in such position as to permit the blank to move forward, and to prevent it from moving back. The blank being fed forward, its end, embracing one tooth, extends beyond the inner end of the giurie-plates p and under the driver, the bender being in the position shown in Fig. 3. The bender is at the foot of a lever, m, pivoted at y, and having an upper arm held normally under a shoulder, or incline, x, of the driver by a spring, z. As the driver descends the shoulder x forces the bender forward, and the bender, striking the blank tooth, throws it forward, as shown in Fig. 4, the continued descent of the driver severing the head, and the nail, guided by the walls of the nail-tube, is J(cilriilren down and into the surface beneath the lt will be observed by inspection of the drawing that the only movable agent in cutting and driving the nail is'the driver c, the driver acting as one member of the shears, and the other shear-blade being the end of the stationary roadway-plates p.
. In the Fischer and Blake patents, 90,650 and 131,080, a blade is brought between the nail to be severed and the next nail, the blankhead resting on the edge of this blade for the action of the driver in severing the nail, and to insure the cutting of one nail only 5 but in my present invention I dispense entirely with such intervening blade, insuring the separation of the teeth (so that one nail and one alone shall be cut) by bending the shank to be out of from the line of the rest of the blank, as described.
A T- shaped blank may be used with a .tool embodying more or less of my present improvements, but I consider the l'- shaped blank to be in every way preferable.
I claiml. A lasting tool or nailer having a guidepassage for the blank set at an inclination to the driver, substantially as shown and described.
2. A lasting tool or nailer having, in combination with the driver, a bender for forcing forward the nail-shank to be severed, substantially as described.
3. A lasting tool or nailer, in which the end of the comb-like blank enters the nail-tube at one angle and is brought to another angle to be severed, substantially as described.
4. The feed-pawl q, and detainer-pawl u, jointed to ,the levers i" and fw, and operated substantially as described.
5. A comb-like nail-blank, having its head formed by bending one edge of the plate, substantially as shown and described.
