Improvements in Means for Carrying and Attaching a Plurality of
Tools or Bits Used in Conjunction with a Brace or other Form of
Socketed Handpiece.
I, WILLIAM HENRY CRAINE HARRISON, Flour-mill Proprietor, of Torrens
Road, Woodville, in the Province of South Australia, do hereby declare the
nature of my invention to be as follows:-
-
This invention relates to improvements upon the subject matter of my earlier
application No. 1562 dated 23 January 1899 which relates to a method of and
means for attaching and carrying a plurality of tools commonly called bits upon a
brace or handpiece provided with a socket to take the tools so that the tools
cannot be mislaid and when required any one of them may be quickly secured
in the socket of the brace or handpiece ready for use.
In carrying out that invention I mount upon or attach to the brace or common
handpiece a rotatable toolholder or sleeve to which the tools are hinged or
attached at their tang end so that when required to be used each tool may
be turned on its hinge and quickly affixed in the socket and when done with
may be swung from the socket and tunnel back on its hinge to.
lic along the sleeve without being detached from the sleeve. The
improvements which I have made since the date of that application relate to
the means for hinging the tools to the sleeve and to the cap for protecting the
points of the tools.
In order that my invention may be clearly understood I will describe the
same with reference to the accompanying drawings, in which,
Fig. 1 is a side view of my invention applied to a carpenter's hand brace.
Fig. 2 is a view of the tang end of the sleeve and the split socket.
Fig. 3 is a central sectional view of portion of the lower part of Fig. 1.
Fig. 4 is a view of the tang end of the sleeve and tools with the outer
disc removed.
Fig. 5 is a section on line ab of Fig. 3.
Fig. 6 is a vertical section of the two discs forming the flange at the tang end.
Fig. is a side view of my invention applied to a simple handpiece.
Fig. 8 is a central section of the same with the upper part of the handle
broken off.
Fig. 9 is a section from beneath on the line e d of Fig. 7.
Fig. 10 represents the lower end of the stem showing the tool socket.
The general construction and operation is described in my earlier patent pre-
viously referred to and will be easily understood from the drawings.
The following description of my improvements applies equally either to the
construction shown in Figs. 1 to 5 or 6 to 9.
The sleeve 1 has at the end adjacent to the tool socket 18 a flange composed
of two specially shaped discs 3 and 4 secured together and having a number of
radial slots 5 across the outer portion corresponding to the number of tools 8
to be attached. These slots divide the flange into a number of cheeks between
which the tools are secured. The inner disc 3 of the flange is rigidly attached
to and forms part of the sleeve 1 but the outer disc 4 is secured to the inner
disc by means of setscrews so that when desired the setscrews may be undone

page_text: and the discs taken apart. Near the outer edge of each disc is an annular
groove 6 of semicircular section so placed that when the two discs are secured,
together the two grooves form a circular annular tube. (See Figures 4 and 6).
Each tool has its tang 9 extended somewhat beyond the usual length the
extension being flattened out and provided near its extremity with a short pro-
jecting pin 10 as shown more particularly in Figure 4. The flattened portion
fits into the slot 5 between two of the cheeks and the pin fits in the circular
annular tube of the flange.
This forms a hinge upon which the tool may be swung as desired either for
affixing in the socket of the brace for work or for returning to its place along
the sleeve when done with.
'
By undoing the setscrews the discs may be separated and any tool can be
detached either for removal or for replacement by one of the same or another
kind.
At the other end of the sleeve is another flange 12 having a series of
recesses 13 corresponding in number and position to the radial slots 5 in the
discs 3 and 4 and of various sizes and shapes to receive the points of the tools 8
as shown more particularly in Fig. 5. In order to retain the points of the
tools in position in these recesses I provide a cap 14 rigidly secured to the
spindle 19 having in a convenient part an opening 15 through which the point
of the tool may be lifted. A sliding plate 16 is secured to the outside of the
cap whereby this opening may be closed.
In the construction shown in Figures 1 to 6 the sleeve 1 is mounted so as to
be capable of rotation upon a spindle 19 one end of which is screwed into the
handle of the brace and the other end is supported by a stay 20 secured to
the tool socket 18.
In the construction shown in Figures 7 to 10 the sleeve is mounted upon
the stem 21 so as to be freely rotatable thereon, the tool holding socket being
formed in the bottom of the stem 21.
When one of the tools is to be used the sleeve is turned on the spindle until
the point of the tool required is beneath the opening in the cap. The sliding
plate is then pushed up and the tool swung round on the hinge at the tang
end. The sleeve is rotated on the spindle until the tool is immediately in front
of and adjacent to the opening in the side of the socket. It is then turned into
place through such opening and secured by turning the thumbscrew.

Improvements in Means for Carrying and Attaching a Plurality of
Tools or Bits Used in Conjunction with a Brace or other Form of
Socketed Handpiece.
I, WILLIAM HENRY CRAINE HARRISON, Flour-mill Proprietor, of Torrens
Road, Woodville, in the Province of South Australia, 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 upon the subject matter of my earlier
application No. 1562 dated 23rd January 1899 which relates to a method of and
means for attaching and carrying a plurality of tools commonly called bits upon a
brace or hand-piece provided with a socket to take the tools so that the tools
cannot be mislaid and when required any one of them may be quickly secured
in the socket of the brace or handpiece ready for use.

page_text: In carrying out that invention I mount upon or attach to the brace or common
handpiece a rotatable tool holder or sleeve to which the tools are hinged or
attached at their tang end so that when required to be used each tool may
be turned on its hinge and quickly affixed in the socket and when done with
may be swung from the socket and turned back on its hinge to
lie along the sleeve without being detached froni the sleeve. The
improvements which I have made since the date of that application relate to
the means for hinging the tools to the sleeve and to the cap for protecting the
points of the tools.
In order that my invention may be clearly understood I will describe the
same with reference to the drawings filed with my Provisional Specification, in
which,
Fig. 1 is a side view of my invention applied to a carpenter's hand brace.
Fig. 2 is a view of the tang end of the sleeve and the split socket.
Fig. 3 is a central sectional view of portion of the lower part of Fig. 1.
Fig. 4 is a view of the tang end of the sleeve and tools with the outer
disc removed.
Fig. 5 is a section on line a 6 of Fig. 3.
Fig. 6 is a vertical section of the two discs forming the flange at the tang end.
Fig. 7 is a side view of my invention applied to a simple handpiece.
Fig. 8 is a central section of the same with the upper part of the handle
broken off.
Fig. 9 is a section from beneath on the line cd of Fig. 7.
Fig. 10 represents the lower end of the stem showing the tool socket.
The general construction and operation is described in my earlier patent pre-
viously referred to and will be easily understood from the drawings.
The following description of my improvements applies equally either to the
construction shown in Figs. 1 to 5 or 6 to 9.
The sleeve has at the end adjacent to the tool socket 18 a flange composed
of two specially shaped discs 3 and 4 secured together and having a number of
radial slots 5 across the outer portion corresponding to the number of tools 8
to be attached. These slots divide the flange into a number of cheeks between
which the tools are secured. The inner disc 3 of the flange is rigidly attached
to and forms part of the sleeve 1 but the outer disc 4 is secured to the inner
disc by means of set-screws so that when desired the set-screws may be undone
and the discs taken apart. Near the outer edge of each disc is an annular
groove 6 of semicircular section so placed that when the two discs are secured
together the two grooves form a circular annular tube (see Figs. 4 and 6).
Each tool has its tang 9 extended somewhat beyond the usual length the
extension being flattened out and provided near its extremity with a short pro-
jecting pin 10 as shown more particularly in Fig. 4. The flattened portion
fits into the slot 5 between two of the cheeks and the pin fits in the circular
annular tube of the flange.
This forms a hinge upon which the tool may be swung as desired either for
affixing in the socket of the brace for work or for returning to its place along
the sleeve when done with.
By undoing the set-screws the discs may be separated and any tool can be
detached either for removal or for replacement by one of the same or another.
kind.
At the other end of the sleeve is another flange 12 having a series of
recesses 13 corresponding in number and position to the radial slots 5 in the
discs 3 and 4 and of various sizes and shapes to receive the points of the tools 8
as shown more particularly in Fig. 5. In order to retain the points of the
tools in position in these recesses I provide a cap 14 rigidly secured to the
spindle 19 having in a convenient part an opening 15 through which the point
of the tool may be lifted. A sliding plate 16 is secured to the outside of the
cap whereby this opening may be closed.

page_text: ..In the construction shown in Figs. 1 to 6 the sleeve. 1 is mounted so as to
be capable of rotation upon a spindle 19 one end of which is screwed into the
handle of the brace and the other end is supported by a stay 20 secured to
the tool socket 18.
In the construction shown in Figs. 7 to 10 the sleeve is mounted upon
the stem 21 so as to be freely rotatable thereon, the tool holding socket being.
formed in the bottom of the stem 21.
When one of the tools is to be used the sleeve is turned on the spindle until
the point of the tool required is beneath the opening in the cap. The sliding
plate is then pushed up and the tool swung round on the hinge at the tang
end. The sleeve is rotated on the spindle until the tool is immediately in front
of and adjacent to the opening in the side of the socket. It is then turned into
place through such opening and secured by turning the thumbscrew.
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
1. In combination with a sleeve having a flange at one end composed of the
discs 3 and 4 forming a circular annular tube across which are a number of
radial slots, a plurality of tools each of which has its tang end extended flattened
and provided with a short piñ projecting on each side, the flattened part adapted
to fit into one of the slots and the pin to fit into and rotate in portions of the
annular tube substantially as and for the purpose set forth.
2. In a tool-holder carrying a plurality of tools capable of swinging from their
normal position alongside the sleeve into the socket of a tool driving instrument,
the combination with a body of a flange at one end composed of the discs 3 and 4
fastened together by set-screws forming a circular annular tube across which
are a number of radial slots adapted to hold the tang ends of the tools, and a
flange at the other end of the sleeve formed with a number of recesses adapted
to receive and hold in their normal position the points of the tools which are
not in use substantially as and for the purpose set forth.
3. In combination a sleeve having a flange at one end composed of the discs
and 4 forming a circular annular tube across which are a number of radial slots.
and having at the other end a flange provided with a number of recesses to take
the points of the tools, a plurality of tools each of which has its tang end
extended and flattened and provided with a short pin projecting on each side,
the flattened part adapted to fit into one of the said radial slots and the pin
to fit into and rotate in portions of the annular tube, and a fixed cap holding
the points of the tools in the recesses of the second flange and provided with
an opening and a sliding plate to removably hold the, points of the tools sub-
stantially as described and for the purposes set forth.
4. The combination with a tool-driving instrument having a socket for
receiving the tools when they are to be driven, of a sleeve mounted to turn
thereon carrying a plurality of tools, said sleeve having at one end a flange
composed of two discs forming a circular annular tube across which are a
number of radial slots adapted to receive the tang ends of the said tools and at
the other end a flange formed with a number of recesses adapted to
receive the points of the tools, and a cap rigidly attached to the tool-driving
instrument and provided with an opening and a sliding plate to removably hold
the points of the tools in place in the said recesses substantially as described.
