OF BRUSHES." A communication from abroad by Messrs. John Gill McMurray,
& Co., of Lansingburgh, New York.
This Invention has for its object improvements in machinery for drilling applicable
to the manufacture of brushes.
The blocks which are to be drilled for the purpose of making brushes are secured
by clips to a line of discs which are pivotted on a plank or frame. The central disc
carries the pattern shewing the positions of the holes which are to be drilled in the
blocks. Any convenient number of blocks (say, 10 or more) are drilled at a time.
A line of drilles carried on the main frame of the machine, and which are driven
from a shaft underneath, are ranged opposite to the line of discs, a drill being
opposite to each disc. These drills always remain in the same position and the
blanks are moved, as is herein-after described, in such manner that the required
holes corresponding in position to those on the pattern are drilled in succession.
The plank or frame carrying the discs is hinged along its central line to a vertical
frame which is suspended by grooved wheels from a horizontal rail which is fixed
to the front of a horizontal overhead framework, which is capable of turning about
its centre line and which carries at its back counterbalance weights which balance
the weight of the suspended frame and of the parts attached to it; thus it will be
seen that the plank or frame carrying the discs can be shifted endwise or can be
raised or lowered at pleasure; in the first case, the hanging frame has only to be
pushed along the rail from which it is suspended, and in the second case the horizontal
overhead framework has only to be slightly tilted one way or other, In this way

page_text: motions of translation either in horizontal or in vertical directions can be given to
the blocks which are being drilled.
A motion of rotation about the centres of the discs is given as follows:-The
peripheries of the discs have on them teeth or holes into which the teeth or pins of
a rack take. On the axis of the central disc which carries the pattern there is a
hand wheel, which when turned turns with it the central disc, thus traversing the
rack, and thereby turning all the other discs. In this way when the hand wheel
on the central disc is moved either to the one side or to the other, is raised, lowered,
or turned, thereby shifting the position of the pattern, each of the blocks is shifted
in precisely the same manner; thus by bringing the holes in the pattern in suc-
cession opposite to a fixed pointer, the corresponding holes are drilled in succession
in each of the blocks.
As the drills penetrate the blocks the plank or frame which carries the latter is
pushed forward by cams at its back; these cams are carried by a horizontal cam
shaft which is driven by a band or gearing from the main shaft in such a manner
that its speed relative to that of the drills can be varied according to the hardness
of the wood which is being drilled.
The inclination of the holes which are drilled in the blocks is regulated as
follows-It has been before mentioned that the plank or frame carrying the blocks
is hinged along its central line to the suspended vertical frame, the plank or frame
carrying the blocks can thus be turned on its hinges, so as to incline at any
desired angle to the vertical, and the holes may therefore be drilled at any desired
inclination to the surfaces of the blocks.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edward James Rooney in the Great Seal Patent Office on the 14th
July 1877.

In order that ny said Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of a machine for drilling constructed according to
my Invention; Figure 2 is a transverse vertical section of the same. In Figure 1
only the central portion of the machine is shewn, the Figure including two discs
acting as work holders on either side of the central disc, which is the pattern
carrier. The machine may, however, be extended to any convenient distance in
either direction.
a, a, is the main shaft; it is driven in any convenient manner, and has upon it a
series of belt pulleys a¹, a¹, receiving belts which drive spindles b, b, carrying drills
at their inner ends. The heads b, b¹, in which the drill spindles are carried are
fixed upon the frame of the machine; c is a head in the centre of the machine
similar to those which carry drills, but in lieu of the drill spindle there is mounted
in it a pointer c. This pointer is pressed inwards constantly by the rod. d to which
it is attached, the rod is connected by a cord to the weight d'; e is a board or
carriage suspended from overhead by the frame f which can be moved horizontally
along the bar
there being rollers upon the frame to run along a rail fixed to the
bar. The bar g also can be raised and lowered with ease, it being carried by the
levers h, h, having fulcrums at l³, h³, and the whole weight of the carriage e, frame f,
and parts connected therewith are counterbalanced by the load i hung from the
levers h. The carriage e carries the centres or studs on which the discs or work
holders k, k, are able to turn; Figure 3 is a front view of one of the work holders
to a larger scale, and Figure 4 is a plan of the same. The holder here shown is suitable
for receiving brush blanks, and holding them whilst they are drilled to receive the
bristles; it has on its face two jaws k¹, k¹, which can be made fast in any desired
position by clipping screws so as to grip between them the brush back, and hold it
in the position shown by means of the teeth or studs on its face. The disc also
carries a gauge to aid in placing the boards accurately.
The form of the holding instruments upon the face of the disc will require to be
varied to suit the shape of the work. There are holes formed at equal distances
apart around the periphery of the disc to receive the pins or teeth of a rack 1. The
disc m, which serves as the pattern carrier, is similar to the work holders, and it has
fixed to it the hand wheel m'. This wheel is held by the workman, and by its
means he guides the carriage e, and when necessary rotates the discs in such manner
as to bring the holes in the pattern in succession opposite to the pointer c', and in

page_text: such a position that each time the carriage swings forward the pointer may penetrate
into a fresh hole.
The pattern may conveniently be made in lead or other metal, and it has
holes in it corresponding both in position and inclination with the holes it is
desired to drill in the brush backs, except that it is convenient to open or counter-
sink somewhat the mouths of the holes, so that as the carriage advances the pointer
entering the hole may correct the position of the carriage before the work comes
into contact with the drills, if the position to which the carriage has been brought
by the workınan be but approximately correct. When inclined holes have to be
drilled it is necessary to set the carriage e to a corresponding inclination to the
drills. To admit of this the carriage is attached by hinge joints to the frame ƒ at
ff; and attached to the back of the carriage board there are bars e¹, el, having
notched arcs e, e, fixed to them. The bars el are able to turn about studs which
connect them with the carriage board, and they are connected the one with the
other by a rod es. By moving this rod endwise the arcs e² can be disengaged from
projections on the frame f with which their teeth engage, and the carriage e is then
free to incline. The workman by pushing the rod e³ from himself or drawing it
forward as the case may require brings the carriage e to the desired inclination, and
then again locks it by making the teeth of the arcs e to engage with the projections
provided for the purpose on the frame f. The carriage e receives its automatic
movement for pressing the work against the drills by means of cams n, n, on a
shaft n¹. These cams operate against small friction pulleys at the back of the
pushing board o. This board is carried upon standards o' which are hinged at their
lower ends to the frame of the machine. The board o is also linked to a weight p
which keeps the friction pulleys upon it against the cams. Projections from the
front edge of the pusher board o rest against the back of the carriage e, and each
time that the cams come round the carriage is thrust forward. The carriage tends
by its own weight to fall away from the drills, but to ensure its return there are
eyes e at its back through which rods fixed to the pushing board pass, so that the
carriage and pushing board are linked together, but in such a manner that the
carriage is left free to move in any direction which the work may require. The
cam shaft n¹ is driven by spur gear from the intermediate shaft q upon which there
is also a clutch for disengaging the gear wheels when it is desired to stop the
movement of the carriage e. The shaft q is driven by a belt and pulleys from the
second intermediate shaft 8, and these pulleys may if desired be coned to vary
the speed of the carriage in relation to the drills, but in the Drawing this adjustment
is not provided; a² is a pulley on the main shaft a to receive the belt by which the
shaft 8 is driven.
Having thus described the nature of my said Invention and the manner of
performing the same, I would have it understood that I claim,-
First. The construction of machinery for drilling with a series of drills, and a
carriage with work holders upon it facing the drills, such carriage and work holders
being moveable by the workman according to the indication of a pattern in all
necessary directions, whilst the pressure to cause the drills to penetrate the work is
automatically applied, substantially as described.
Second. The construction of machinery for drilling, substantially as described and
represented in the annexed Drawings.
In witness whereof, I, the said Edward James Rooney, have hereunto set
my hand and seal, this Thirteenth day of July, in the year of our Lord
One thousand eight hundred and seventy-seven.
