PROVISIONAL SPECIFICATION.
Improvements in Pegging, Nailing, Sprigging, Rivetting, and other
similar Machines.
I, THOMAS GARE, of The Gare Machine Co. Ltd., of Carrs Iron Works,
Stockport, in the County of Chester, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in pegging, nailing, sprigging, rivetting,
and other similar machines in which the object to be operated upon is supported by
means of a horn or other support carried by a shaft rendered vertically movable in
its bearings.
Heretofore the said horn or support has been forced against the object under
operation during the driving in of the awl and the peg, nail, sprig or rivet by
means of a spring or weight which do not give the required amount of resistance
and cause the peg, nail, sprig or rivet to be driven in imperfect.
To remedy this defect my invention has for its object to provide means whereby
the shaft of such horn or support is rendered vertically rigid during the driving in.
of the awl and that of the peg, nail, sprig or rivet and released again on the
material under operation being fed.
To this end my invention consists in locking or gripping the said shaft by
suitable means either in, on, or between the respective bearings and thus render its
horn or support vertically rigid during the period of driving the awl and
peg, nail,
sprig or rivet into the material under operation whilst it is released again on the
latter being.fed.
This my invention may be carried out in various ways:
According to one form I split the said bearing or its bush on one side so as
to allow of it being drawn together and thereby grip the said shaft firmly, whilst
on being slightly opened it releases it vertically, or I may suitably force a wedge
shaped or straight key, arranged in the said bearing, against the said shaft.
Another form of my invention consists in employing between or above the said
bearing or bearings a clip or gripper arranged to grip and lock the shaft vertically
in position on being drawn together and to release it on being opened.
The said split bearing or bush, key, clip or gripper may be tightened or released
by means of a threaded spindle and nut, or by a plain spindle having a cam face
operating against a stationary cam face.
In each case the said spindle is operated from a cam on the driving shaft and
suitable connections, such as rod and levers.

COMPLETE SPECIFICATION.
Improvements in Pegging, Nailing, Sprigging, Rivetting, and other
similar Machines.
I, THOMAS GARE, of The Gare Machine Co. Ltd., of Carrs Iron Works,
Stockport, in. the County of Chester, Engineer, 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 invention relates to improvements in pegging, nailing, sprigging, rivetting,
and other similar machines in which the object to be operated upon is supported by

page_text: a morn or other support carried by a shaft rendered vertically movable in
its bearings.
Heretofore the said horn or support has been forced against the object under
operation during the driving in of the awl and the peg, nail, sprig, or rivet by
means of a spring or weight which do not give the required amount of resistance
and cause the peg, nail, sprig or rivet to be driven in imperfect.
To remedy this defect my invention has for its object to provide means whereby
the shaft of such horn or support is rendered vertically rigid during the driving in
of the awl and that of the peg, nail sprig, or rivet and released again on the
material under operation being fed.
To this end my invention consists in locking or gripping the said shaft by
suitable means either in, on, or between the respective bearings and thus render its
horn or support vertically rigid during the period of driving the awl and peg, nail,
sprig, or rivet into the material under operation whilst it is released again on the
latter being fed.
This my invention may be carried out in various ways and in order that the same
may be more fully understood I have caused to be appended hereunto one sheet of
drawings marked with letters of reference indicating like parts in the various
figures.
Fig. 1 is a back view, Fig. 2 a side view of Fig. I, and Fig. 3 a sectional plan
of Fig. 2 of the middle portion of a pegging, nailing, sprigging, rivetting or similar
machine, showing one form of my invention applied.
Figs. 4 & 6 are sectional front views, Figs. 8 & 10 side views and Figs. 5, 7, 9
& 11 respectively plans showing four other forms in which my invention may be
carried out.
Referring to Figs. 1, 2 & 3, according to one form of my invention I split the
bearing a (or its bush) on one side, so as to allow of it being drawn together and
thereby grip the horn or support shaft b firmly, whilst on being slightly opened it
releases it vertically, or I may suitably force a wedge shaped key c, see Figs. 4 & 5,
or a straight key d, see Figs. 6 & 7, arranged in the bearing a, against the horn or
support shaft b.
Another form of my invention consists in employing between, above, or on the
bearing or bearings a a clip or gripper e, see Figs. 8 & 9, arranged to grip and lock
the horn or support shaft b vertically in position on being drawn together and to
release it on being opened.
Another way of locking the horn or support shaft b vertically in position is by
employing a cam lever 6', see Figs. 10 & 11, to press against the same.
The split bearing a, or bush, keys e & d, clip or gripper e may be tightened or
released by means of a threaded spindle f and nut f similar as shown in Figs. 8 & 10
in the clip or gripper e, or preferably by a plain spindle or shaft f, see Figs. 1, 2 & 3,
having a cam face g operating against a stationary cam face g'.
In each case the spindle for cam lever b' is operated from a cam, or by preference
by a bowl on the cam i which actuates the horn lever k and is fixed on the driving
shaft and suitable connections, such as rods & land levers m & k.
The upper end of the rod is suitably guided on the frame n and the loose end
jointed to the lever m of the movable cam surface g and serve to lock the shaft b in
its bearing a, clip or gripper e when required, whilst the upper end of the rod lis
jointed to the horn cam lever k and the lower end is connected to the cam lever m
and serves to unlock the shaft 6 in its bearing a clip or gripper e when required.
A handle c¹ may be employed on the spindle f to operate the same by hand in
lieu of by the rod / if required.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim, is-
"In pegging, nailing, sprigging, rivetting and other similar machines,"
1st. The general construction and combination of parts constituting my improve-
ments operating substantially as and for the purpose specified.

page_text: 2nd. The application of a device for locking or gripping the horn or support
shaft bin, between, on, or above the respective bearing or bearings whilst driving
the awl and peg, nail, sprig, or rivet into the object under operation substantially
as and for the purpose specified.
