COMPLETE SPECIFICATION.
An Improved Nailing Device for Securing Carpets, and other like
purposes.
I, REINHOLD BOEKLEN, of No. 492 Decatur Street, Brooklyn, New York,
United States of America, Mechanical Engineer, do hereby declare the nature of
this invention and in which manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
One essential feature of this invention relates to the combination, with a magnetic
bar hammer or nail driver, of a poor conducting nail guide, and of a nail take-off
fork, for the purpose of guiding the nail in picking up and placing the same to the
spot to be driven, and in picking up the nail, to expel others surplus from it.
A secondary feature relates to the combination of a magnetic bar hammer, and
its guide with a nail entrance of a claw bracket with a guide for said hammer and
a connected stretching lever for nailing carpets.
Other features relate to details more fully set forth in the Specification and
claims.
In the annexed drawings:
Figure 1, represents a sectional side elevation of the nail or tack driver, and
the same connected with a carpet stretching device all according to my
improvements.
Figure 2, is a detached vertical section of the lower portions of the hammer
and its guide; the hammer shown in the act ready to pick up the nail or tack.
Figure 3, is a side elevation of the hammer shown when applied to over-head
nailing.
Figures 4 and 5 are perspective views of the details of the carpet stretching
attachments connected with the magnetic hammer.
Figure 6, is a detached face view of the take-off spring of the hammer.
The letter "A" of reference indicates the magnetic bar hammer and rod of the
nail driver, and "B" the nail guide which passes over it readily. Said hammer
may be made of one rod of steel, either only the lower portion or the whole
hardened. It is magnetized to attract suitably the size nail to operate upon.
In some cases said hammer may be made with only a short magnetized portion of
the lower end, and may be of hard cast iron and enclosed in an outside brass tube,
or other poor magnetic conductor, and said tube jointed to a brass rod for the
remaining portion of the hammer.
Said hammer may not have any insulator or poor conductor over any portion
thereof, or it may have only a short covering a over the sides of the lower end,
which covering may be of rubber, aluminum, brass or other poor conductor.
Or the covering a may cover considerable of the lower portion or the whole length
of the rod. Generally the top end of the hammer is furnished with a handle C
it may
which is made weighty and is solidly secured to the end of the hammer rod;
be solid of one metal, or may be of an outside suitable metal shell and made
weighty by filling the inner portion or core with lead. The guide "B" is
preferred of tubular form; it allows the hammer to slide readily therein; its top
end is preferred to have a projection or button b on it to provide for a stop against
dropping from the hand of the operator. It is preferred to be made of aluminum
or brass tubing or other poor magnetic conductor, and may be the whole length of
the same dimension or may be partly of another diameter. It is preferred that the
hammer have a stop from dropping but little with its bottom and below the bottom
end of the guide "B," and that a stop be provided to prevent the hammer from
withdrawing entirely from the guide "B," To provide the stop for the hammer

page_text: going down unduly, the bottom end of the handle "C" is made to come in
contact either directly with the top of the guide "B," or with a spring "D"
upon said guide; and to provide and stop the hammer from withdrawing entirely
from the guide "B," a suitable shoulder is provided on the lower end of the
hammer as shown in Figure 1; said shoulder may be made by the poor conducting
metal over said lower end, and having the hammer rod smaller and the bore of the
button 6 to fit it, the hammer is prevented from withdrawing. The handle "C." in
this case is secured to the rod by a screw thread joint.
The bottom end of the guide "B" has on one or more sides of it the tack or nail
entrance "E," the base of which commences at the bottom end of the guide "B"
and terminates at a certain height, closing with a point. Its dimension in width
depends upon the size of the head of the nail operated upon, and is made always a
little larger than said head. The height of the opening or entrance "E" is made
to suit the length of the nail to allow it to raise and pass within the guide readily.
On the opposite side of the lower portion of the guide to the entrance "E" and a
little above it, is provided the take-off fork "F" which is formed of a vertical flat
spring secured to the outside of the guide "B," and its bottom end enters through
an opening "G," into the guide and terminates with two prongs t one to each side
of the nail shank, when raised by the magnetized hammer end, as shown in
Figure 1, so that by the act of raising the nail to be driven with the hammer,
a secondary nail or surplus having attracted to the shank of the first will come in
contact with its head, with the take-off fork and is caused to drop down, or is
expelled; or if the nail is picked up by the point, it is expelled by contact of its
'head' with the take-off spring "F."
As soon as the hammer comes down, just before picking up a new nail, said take-
off fork is forced outward out of the way, by contact with the hammer, as shown in
Figure 2; more than one take-off spring "F" may be employed, but its movement
is always in time to come inward for taking off the surplus nail, when the hammer
moves upward, but coming down to move outward, and at all times, stay outward
away from the passage of the nail, except at the moment when the nail shank passes
it going up and then expelling any surplus nail. The nail driver may be used in
spreading the nails to be picked far apart, without the take-off fork, more especially
with large nails, but for small tacks the take-off is very useful, and almost
indispensable.
When the nail driver with the guide "B" is placed upon the spot for the nail to
be driven, and the hammer, with a previous picked up and raised nail, is readily
driven home.
The hammer is extremely convenient for all driving of small nails on account of
having the guide "B" to place the nail accurately to the spot or nail line designed
'for its being placed, and also by reason that the magnetized hammer picks the
nails up quicker than by hand. For tack nailing and nail withdrawing I provide
on the guide "B a suitable claw "X" as shown in Figure 2.
"
The hammer can be made of any suitable length for overhead nailing, it may be
sufficiently long to drive nails in the ceiling of a room from the floor; and overhead
nailing with this hammer is done with convenience and rapidly while 'such nailing
with the ordinary hammer is very tiresome and slow on account of requiring the
elevated, and very inconvenient position of the arms.
For carpet 'nailing, 1 combine and provide this hammer 'with a carpet
stretcher "H"shown, which consists of a three armed claw bracket "K," to which
is attached a foot-lever "L" with a carpet fork. The three armed bracket "K"
has a sharp claw "M" which is driven in the joint of the baseboard or the wall
with the floor and rests with its secondary sharp claw "N" upon the floor; to
prevent its slipping from 'the wall or baseboard. The third and vertical arm of
this bracket serves as a lever and to its top end is connected and attached the
upward short arm "O" of the foot lever "L" by a rope or link "T," and also the
hammer guidé "P," which-latter rests with its loose end upon á movable collar "Q"
secured över 'the'guide "B" of the hammer. The teeth of the "fork “R” take

page_text: hold into the carpet and the foot lever
back of its fork, which roller rests upon
upon the long arm "V" of the said
"L" has a friction roller "S" close at the
te," the carpet is stretched and a nail
the carpet and by pressing with the foot
or tack picked up from the carpet and driven down by the hammer through the
carpet, secures the stretched portion to the floor, after which the hammer and
stretcher are moved to the following portions of the carpet to be stretched and
nailed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In nail drivers or hammers the combination with the magnetic bar hammer of
a nail guide "B" with its nail entrance "E," substantially as and for the purposes
herein set forth.
2. In nail drivers and hammers the combination with the magnetized hammer of
a nail guide "B" and a take-off device or spring "D," substantially as and for the
purpose herein set forth.
3. In nail drivers and hammers, the combination with the magnetized hammer of
a nail guide "B," a nail entrance "E," from the base up on the side of a narrowing
structure and the take-off fork or spring "F," substantially as and for the purpose
herein set forth.
4. In a nail driver, the combination with the magnetized hammer of a nail
guide "B," with stops for undue descent therein of the hammer, and the upward
narrowing nail entrance "E," and the take-off fork or spring "F," substantially as
and for the purpose herein set forth.
5. In nail and tack drivers a carpet nailing instrument consisting of a magnetic
bar hammer "A" with a guide "B" having a nail entrance "E," a claw
bracket "K," with its hammer guide "P" and the attached foot lever "L,"
substantially as and for the purpose herein stated.
6. In carpet or cloth nailing instruments, the combination with the magnetic bar
hammer "A and its guide "B" with its nail entrance "E" of the claw
bracket "K" for guiding the hammer "A" and a suitable cloth stretcher
connected with said bracket "K," substantially as and for the purpose herein
set forth.
