and other Nails.
We, THOMAS HENRY ACKROYD, of Birkenshaw Mills, Birkenshaw, near Leeds, in
the County of York, Spinner and Manufacturer, and ALLAN BROADLEY, of the same
place Manager do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
This relates to certain improvements in the method of and apparatus for driving
Tacks, and other Nails, and is more especially applicable to the more expeditious mode
of nailing card clothing to the cylinders of a carding Engine. The improvement is
also useful for driving nails for all other purposes.
In covering the cylinders of carding Engines, hitherto the tack or nail is often of
less length than the length of the wire forming the card it is placed between the wires
of the card clothing by the finger and thumb and by means of an ordinary punch
placed with some difficulty upon the head of the tack and a hammer it is driven
home with a result which is detrimental to the surface of the card in as much as
some of the wires are often driven down with the nail thus reducing the carding
surface.
By our improvements there is no detriment to or reduction of the card surface, and
in addition to the advantage of doing the work better, it is done more expeditiously
than hitherto.
We accomplish our object by forming an apparatus, the lower end of which is formed
like a leather punch with an aperture in the side about two inches from the bottom
having an inclination to the vertical line of the punch, the upper portion of the Tool
or apparatus is prepared to receive a steel spindle of about the length of the tool
terminating at the top in a head to receive the blow of a tack hammer, this spindle
can be lifted clear of the side aperture down which the tack falls into position for
driving, the spindle is then dropped on to the head of the tack and driven home with
the hammer in the case of securing clothing to carding Engines when effected by
our improved apparatus it is difficult to detect where the nail has been driven in, as
the card surface is comparatively (with the old method) undisturbed.

page_text: In order to better illustrate our invention, we will further describe the same by aid
of the accompanying drawings in which,
Fig. 1. represents a side elevation of our improved apparatus for driving tacks and
nails.
Fig. 2. is a front view, and
Fig. 3. is a section through the same.
The apparatus is made with the lower end formed like a leather punch with an
aperture A in the side about two inches from the bottom and having an melination to
the vertical line of the punch.
The upper portion of the apparatus is prepared to receive a steel spindle B. of
about the length of the tool terminating at the top in a head H. to receive the blow of
a tack hammer. The spindle B. by means of the projecting piece C. is lifted clear
of the side aperture A. down which the tack falls into position for driving home.
The spindle B. is then dropped on to the head of the tack and driven home with the
hammer, in the case of securing clothing to carding Engines when effected by our
improved apparatus as it is difficult to detect where the nail has been driven in. After
driving home the tack, or nail, the spindle B. is returned to its normal position by
means of spiral spring D.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
The annaratus substantially as and for the nurnosa horain dozoribad
