Improvements in Nailing, Sprigging, and Pegging Machines .
employed in Boot and Shoe Manufacture.
I RICHARD WILKINSON BATEMAN of 8 Hanover Street, Halifax in the
County of York Shoemaker, do hereby declare the nature of this invention to be as
follows:-
This invention relates firstly to improved adjustable feed motion for the nails
sprigs or revits. Secondly to an improved anti friction or travelling horn designed
to obviate the frequent binding and breakage of prickers.
According to this my invention I employ a feed motion comprising a toothed
segment arm operated by a cam and runner the segment teeth goar with and drive.
a pinion loose on the axis of the driven milled feed roller attached to said pinion is
a fiugor carrying a ratchet for operating a pinion fast ou the axis of the feed roller
adjoining the said ratchet is a collar and disc loose on the feed axis and on the said
collar is a scroll piece the disc is notched or provided with an index and locking
piece. When it is desired to adjust the feed to any particular length of revit the
index disa is set and the scroll on the boss is at the same time moved so as to
interpose the ratchet and thereby prevent or allow its pushing the ratchet wheel
more or less round and so moving the feed rollers accurately to the length of revit
required.
For feeding nails along a guide or channel when such nails have been partially
prepared by nearly severing the bar from which they are made, I employ a slide.
and pall the point of the latter entors the nick or recess where the bar is nearly
Bevored between two heads of nails and as the slide moves forward and pushes the
bar forward equal to the width of the head of the required nail. The slide
carrying the paul is operated by a scroll or wiper tappet acting on an anti-friction
bowl moves the slide in one direction said slide being returned by means of a spring
or other like device, the relative movement of the slide and pall are determined by.
adjustable stop piece and the antifriction bowl which through the wiper, tappet
operates the slide as described is also adjustable on the slide for the purpose of
adjusting the action to different widths of heads of nails and for the purpose of
ensuring the head of the nail being centrally placed immediately under the
plunger..
The autifriction horn or "stoop "consists of preferably three pulleys arranged
in form of triangle and having over them a chain or sectional belt of leather one
of the pulleys being adjustable for tightening or for facilitating removal of the
belt. The sole of the boot or shoe bearing on the belt receives the point of the
pricker and as the latter is often forced entirely through the sole, the pricker on
being moved forward, carries with it the sole and sectional belt, and so avoids
breakage of the pricker as was conimon when the horn or "stoop" was stationary.
Dated this 27th day of January 1893.

page_text: teeth of the ratchet wheel 10, and the latter is moved forward part of a revolution,.
and carries with it the axis 5 and milled feed roller 6, which feeds the wire or
rivets as ordinary. When the segment arm 1 moves the finger 7 back, the pawl or-
ratchet 8 moves inoperatively over the teeth of the ratchet wheel 10 and onto the.
scroll 12. It will be seen that when the ratchet 8 is on the scroll 12 it cannot.
operate on the teeth of the ratchet wheel 10, but as soon as it passes off such scroll,.
it engages with the teeth, and operates the "feed." By turning round the scroll 12
on the axis 5 the active movement of the ratchet or pawl 8 is adjusted and regulated,.
as is also the length of the "feed."
The anti-friction horn or "stoop" (see Sheet 4) consists of preferably three.
pulleys 1, 2, 3, arranged in the form of a triangle, said pulleys being carried in a
fork-like bearing 4. One of the pulleys 3 is mounted in the slots 5, 5, and the
adjusting screws 6, 6 bearing on the axis of the pulley 3, the position of the latter
can be adjusted. A chain or bolt of leather 7 passes round the three pulloys 1, 2, 3
and by the pulley 3 being made adjustable, the belt or chain 7 can be tightened or
slackened for facilitating removal of the belt or chain 7. At 7 is a support between:
the pulleys 1, 2.
When the "stoop" or horn consists of one pulley 1 only (see Figs. 18 and 19).
such pulley is mounted in a fork-like bearing 4. The pulley 1 consists of two
flanged collars 9, 10 one collar 10 having a "she" thread, and the other collar 9
a "he" thread. A disc or washer of leather 7 is placed on the collar 10, and the
collar 9 is then screwed into the collar 10, so that the disc or washer 7 is nippod
between the flanges of the collars and securely hold thereby. A ring or projection 14
on each flange indents the leather 7 near its periphery, and prevents the outor edge..
of the leather collapsing or being knocked out of shape after continued use.
The sole of the boot or shoe bearing on the belt, chain or leather 7, receives the
point of the pricker, and as the latter is often forced entirely through the sole, tho
pricker on being moved forward, carries with it the sole and belt, chain of leather
or washer 7, and so breakage is avoided.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what.
I claim is :-
(1.) The general construction, arrangement, and combination of parts constituting
the improved feed motion, together with the means of operating same as herein
described and substantially as illustrated by Figs. 1, 2, 4, and 5 of the accompanying
drawings.
(2.) The toothed segment arm 1, pinion 4, finger 7, and catch or pawl 8, ratchet.
wheel 10, notched disc 11, and scroll 12, all in combination, and as and for the
purpose herein described, and as illustrated by Sheets 1, 2, and 3 of the accom-.
panying drawings.

"
(3.) The improved anti-friction horn or
consisting of the three.
pulleys 1, 2, 3 surrounded by a chain or belt of leather 7, said pulleys being.
mounted in a fork 4, as and for the purpose herein described, and as illustrated by
Figs. 25, 26, 27 and 28 of the annexed drawings."
(4.) The improved anti-friction horn or "stoop" consisting of the two flanged
collars 9, 10, said flauges having projections 14 formed on them together with the
leather washer or disc 7, and tho carrying bracket 4, all in combination, and as and
for the purpose herein described, and as illustrated by Figs. 18 to 24 inclusive of
the accompanying drawings.
