Improvements in Pegging, Nailing, Rivetting, and other Machines, in
which the Object to be Operated Upon is Supported by a Horn.
I, THOMAS GARE, of the Gare Machine Co. Ltd., of Carrs Ironworks,
Stockport, in the County of Chester, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates more particularly to improvements in a machine for which
Letters Patent, No. 13751, bearing date September, 24th 1888, has been granted
to me, but which improvements are equally as well applicable for pegging or
nailing machines of other construction and for other machines where the
object under operation is supported by a horn, such as rivetting and bunking
machines, etc.
Heretofore in pegging or nailing machines, owing to the varying thickness of
the object under operation, the horn supporting the same is dropped irregularly,
which is liable to damage the awl and the object under operation and makes the
machine difficult to operate.
The object of my improvements is principally to remedy this defect, by providing
means whereby the horn, each time the feeding of the object takes place, is dropped
a uniform distance from the object under operation irrespective of the thickness
thereof. This I accomplish by forming a loose connection, between the lever
which drops the horn and the lever acted upon by the respective cam, which the
moment the drop of the horn is to take place becomes rigid.
According to one form of my improvements I hinge to the lever which raises the
horn shaft a rod which is guided in suitable bearings and on which is permitted to
slide a gripper, jointed to a link hinged to the respective cam lever. This
gripper is permitted to rest on an adjustable plate and is formed with a hole
of a size larger than the diameter of the said rod in order to permit the gripper
of sliding loosely thereon, until it is time for the horn to drop. At this time
the gripper has taken up an inclined position and is thus caused to grip and
lift the said rod and thereby effect the drop of the horn, after which the
gripper will fall back to its original position assisted by a finger made adjustable
on the aforesaid link. By either raising or lowering the plate on which the
gripper rests, more or less drop can be given to the horn. To make the knife
which cuts the ends of the pegs or nails off level with the under side of the
object under operation more certain in action, I form also a loose connection
between the lever operating the said knife and the rod acted upon by the
respective cam. The said rod I form in two parts which I guide in a suitable
bearing and provide respectively with a collar. The rod acted upon by the said
cam is under the influence of a spring and the said collar made adjustable thereon.
The other of the aforesaid collars rests loosely on a spring placed on the respective
rod and is held thereby in contact with the underside of the first named collar.
The hole in the second named collar is larger than the diameter of the rod thus
permitting the said collar to slide loosely on its rod until the first named disc has
moved it in an inclined position, when it will grip and depress the respective rod
and effect the cutting off of the peg or nail; after which it returns to its original
position. By either raising or lowering the first named collar on its rod, more
or less movement can be imparted to the said knife. A loose connection similar
to those described may also be formed by employing a pair of jaws in connection
with the parts referred to and operated upon by the respective cams.
According to another form of my improvements 1 form a loose connection

COMPLETI SPECIFICATION.
Improvements in Pegging, Nailing, Rivetting, and other Machines. in
which the Object to be Operated Upon is Supported by a Horn.
I, THOMAS GART, of the Gare Machine Co. Ltd., of Carrs Ironworks.
Stockport, in the County of Chester, Engineer, do her by declare the nature of
this invention and in what manner them to be performed to be particularly
described and certained in and by the following fatement:
-
This invention relates more particularly to improvements in a unchine for which
Letters Patent. No. 13731, bearing dute September, 24th 1858, has been granted
to me, but which improvements are equally as well applicable for pegging or nailing
machines of other construction and for other machines where the object under
operation is supported by a horn, such as rivetting and bunking machines, etc.
Heretofore in pegging or nailing machines, owing to the varying thickness of the
object under operation, the horn supporting the same is dropped irregularly, which
is liable to damage the awl and the object under operation and makes the machine
difficult to operate.
The object of my improvements is principally to remedy this defect, by providing
means whereby the horn, each time the feeling of the object under operation takes
place. droppal a uniform distance from the same irrespective of the thickness
thereof. This accomplish by forming a loose connection, between the lever which
drops the horn and the lever acted upon by the respective eam, which, the moment
the drop of the horn is to take place, becomes rigid.
And in order that my invention 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 ligures.
Figs. & 4 are side views, Figs. 2, 3 & 5 are back views of my improvements as
applied to a pegging machine in various forms.
In carrying out my invention and referring to Figs. 1 & 2, according to one form
of my improvements, I hinge to the lever a, which raises the horn shaft. b, a rod e
which is guided in suitable bearings and on which is permitted to slide a
grippere jointed to a link hinged to the respective cam lever . This gripper e
is permitted to rest on an adjustable plate and is formed with a hole of a size
larger than the diameter of the rod in order to permit the grippere of sliding
loosely thereon, until it is time for the born to drop. At this time the gripper e
has taken up an inclined position, see dotted lines Fig. 2, and is thus caused to grip
and lift the rode and thereby effect the drop of the horn 6, after which the
gripper falls back to its original position, assisted by a finger ¹ unade adjustable
on the aforesaid link. By either raising or lowering the plate
gripper rests, more or less drop can be given to the horn b.

the object under operation, more certain in action, I form also a loose connection
between the lever operating the knife and the rod acted upon by the respective
cam The said rod I form in two parts, which I guide in a suitable
bearing and provide respectively with a collar m, m'. The rod acted upon by
the ram g', is under the influence of a spring and the collar m made adjustable
thereon, by means of nuts m². The other collar rests loosely on a spring
placed on the rod and is held thereby in contact with the underside of the
collar m.
The hole in the collar is larger than the diameter of the rod /
thus permitting it to slide loosely on the rod until the collar m has moved it in
an inclined position, see dotted lines Fig. 2, when it will grip and depress the
rod and effect the cutting off of the peg or nail, after which it returns to its
original position. By either raising or lowering the collar m on its rod 1, and
fixing it in position, by means of the nuts m², more or less movement can be
imparted to the knife. A loose connection similar to those described may also be
formed by employing a pair of jaws e, see Fig. 3, in connection with the parts
referred to riz. the rod, lever and rod operated upon by the cam g',
Figs. 1 & 2.
The jaws e, see Fig. 3, are jointed to a sleeve placed on the rod c (or rod 1,
Figs. 1&2, as the case may be) and to links e jointed to a link e', which is
connected to the cam lever. When the latter is at rest, the jaws e, are out of
contact with the rod, thus permitting the sleeve e to freely slide thereon, until
the links e&are drawn in the direction of the arrow by the action of the cam
lever which causes the jaws e to bind against and lift the rode and thereby drop
the horn . The free ends of the jaws e and the rode may be formed plain, as
shown in Fig. 3, or they may be formed with fine teeth which ensures a quick and
reliable grip on the rod c. When the jaws e are out of contact with the rod c the
sleeve e is permitted to rest on an adjustable plate h, as is the case with the
gripper e, shown in Figs. 1 & 2.
According to another form of my improvements, see Fig. 4, I provide a loose
connection between the horn lever a and respective cam lever g, shown in the figs.
previously described, by forming the lower end of the respective connecting rod c
with a rack e, in conjunction with a toothed segment, formed on a lever c³,
connected to the horn lever a by means of the link a'. The rod and rack c, c¹ are
retained in a raised position and out of gear with the toothed segment c², by means
of a spring e, until the horn is required to drop, which is effected by the rack c
coming into gear with the toothed segment and thereby operating the same and
the horn lever a, through link a' in the direction of the arrow.
The knife i, see Fig. 1, which cuts the ends of the pegs or nails off' level with
the underside of the object under operation may be similarly operated by means of
a rack and toothed segment, as described in case of the horn b'.
Fig. 5 is a modification, partly of Fig. 3 and partly of Fig. 4, which I prefer to
use owing to its simplicity, durability and certainty in action. It consists in
forming the rods & with small teeth and placing thereon a sleeve e², similar
to that shown in Fig. 3, but having only one jaw e jointed thereto. When applied
to the rode the jaw e is attached to the cam lever by means of the link and
when applied to the rod directly to the rod l. In each case the free end of the
jawe is formed with teeth e, adapted to engage corresponding teeth e formed
respectively on the rods c & , so as to lift the latter and thus drop the horn
when required, an adjustable plate being also provided in connection with the
rod c, for the sleeve to rest on, as hereinbefore described and shown in Figs. 1,
2 & 3. The sleeve on the rod is supported by a spring n' and the rod / by the
spring bearing against the collar and the bearing d, in which latter the
rods " 1 & are guided.
Without particularly describing and illustrating the application of the fore-
going forms of loose connection between the horn lever and respective cam, it
vill be easily understood how the same may be carried out in rivetting, bunking
or other machines where the material to be operated upon is supported by a horn.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim, is-
"In pegging. nailing, rivetting and other machines in which the object to be
operated upon is supported by a horn,"
1st. The method of operating the horn lever (and knife lever in a pegging
machine) by forming between the same and the respective cam lever or cam. a
connection, which, when the horn or knife is at rest, is loose and when required
to drop or cut respectively, becomes rigid, substantially as and for the purpose
set forth.
2nd. The various forms of lanse connections between the horn lever (and knife
lever in a pegging machine) and the respective cam lever or cam, as described
and shown and modification thereof, substantially as and for the purpose set forth.
