IMPROVEMENTS IN LOCK FURNITURE
Year: 1884

page_text: I EDMUND SQUIRE NORCOMBE of 107 Bath Row, Birmingham, in the County
of Warwick Engineer-do hereby declare the nature of my invention for
IMPROVEMENTS IN LOCK FURNITURE to be as follows: And relates to attatching
the Knob or Handle to the Spindle, by employing a Slide and Spring made
of one piece of metal-into the base of the spring is rivetted a Pin, the other
end of which projects-through a hole-on the outside of the Neck or Knob―
the whole is inserted into a recess around the spindle hole in the Neck. The
spring pressing-longitudinally on the side of the Spindle opposite to the one.
having the Ratchets or Slots cut therein forces the inner lower edge of the Slide,
into one of the Ratches or Slots, and so holds the Knob firmly in its place. By
pressing on the Pin with the Thumb Nail, the Slide is pressed out of the Slot or or
Ratchet, and the Knob can be easily taken off, without the aid of any implement.
The outside, or Shell of the Knob and Neck, I prefer making of sheet metal, in
three parts, which are made the shape required, so as to go into each other, when
by being soldered together, are virtually one piece, and the seperation of the Knob
from the Neck so frequently complained of, is prevented-I also improve the
"Rose" by partially cutting out and bending to right angles, three wedge shapes
pices, from that part of the stamped Rose, which is covered and hid by the base of
the Knob, these wedges being bent to an angle form "brads or tacks," and are
diven into the door, so fixing the Rose, as to prevent it moving around with the
spindle, and wearing away the wood. I also fasten small "Tacks or "Tingles " to
the back of Cast Metal," Glass, and China Roses for the same purpose.

Slide and Spring, having a hole pierced at the base of the spring for the Pin B to
be rivetted therin. Fig 2 is a front view shewing the Slide and Spring-the
latter pressing on the spindle, having the opposite inner edge of the Slide in one of
the slots in the Spindle. Fig 3 is a side view of the same, shewing the spring and
the Pin B. When the Knob is fixed outside the street door, the Pin is discarded,
and a narrow strip of the Slide-indicated by the dotted lines b¹ Figs 2. and 3-is
carried through a slot in the handle, and the Rose having a deeper recess in which
the Knob rests, prevents the slide being acted upon-and the Knob cannot be stolen.

or
I EDMUND SQUIRE NORCOMBE of 107 Bath Row Birmingham in the County of
Warwickshire-Engineer-do hereby declare the nature of my invention for
"IMPROVEMENTS IN LOCK FURNITURE" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement: and relates to attaching the Knob or Handle to the Spindle by
employing a Slide and Spring made of one piece of metal, into the base of the
spring is riveted a pin, the other of which pin projects through a hole in the Neck
of the Knob. The whole is inserted into a recess around the Spindle hole in the
Neck of the Knob. The spring pressing longitudinally on the side of the spindle
opposite to the one having the Rachets or Slots cut thereon, forces the inner lower
edge of the Slide into one of the Ratchets or Slots, and so holds the Knob firmly in
its place. By pressing on the Pin with the Thumb Nail the slide is pressed out of
the Slot or Ratchet and the Knob can be easily taken off without the aid of any
implement. The outside, or shell of the Knob and Neck I prefer making of sheet
metal in three parts which are made the shape so as to fit into each other when by
being brazed together are virtually one piece and the seperation of the Knob from
the Neck so frequently complaind of is prevented. I also improve the "Rose" by
partially cutting out and bending at right angles three wedge shape pieces leaving
them attached to their base-from that part of the stamped Rose which is covered
by the base of the Knob. These wedge's being bent to an angle form "Brads or
Tacks" and are driven into the door, so fixes the "Rose as to prevent its moving
around with the Spindle and so wearing away the wood. I also fasten small
"Tacks"
or "Tingles" to the back of cast metal, Glass or China Roses for the same
purpose. The accompanying drawing will assist in explaining the said invention.
Fig 1 represents a punching of the combined "Slide and Spring" having a hole
pierced at the base of the spring for the pin B to be riveted therein. Fig 2 a front
view shewing the Slide and Spring C the latter pressing on the spindle having the
opposite inner edge of the Slide in one of the slots in the spindle. Fig 3 is a side
view shewing the spring and the Pin B. A, the Spindle having slots and ratchets.
(When the Kuob is used outside the street door the pin is dispensed with and a
narrow strip indicated by the dotted lines b¹ Figs. 2 and 3, it is carried through a
slot in the handle, and the "Rose" having a deeper recess in which the Knob rests,
"

page_text: prevents the slide being acted upon, and the Knob cannot be stolen. A is a
modification having a longitudinal slot in the spindle for the Spring C to travel in.
Fig 4 are sections of the three parts or pieces, made of sheet metal to form the shell
of the Knob D, of which D' is the plan having a recess the depth of which is the
thickness of the Slide. Fig 1 is inserted into E and rests on the shoulder E¹, the
piece F, is then pressed on to the step at E' and three parts are brazed together at
their junction the Slide, Spring and Pin are placed in the recess in D', a Washer G
having a square hole to fit the spindle, is placed thereon and the edge of the shell
is spun or pressed over the several parts thus completing the Knob. Fig 5 being a
section thereof. Fig 6 a plan of the pressed "Rose." Fig 6° a section of same,
shewing the " Brads or "Tacks."
"
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.
First the making the Slide and spring of one piece of metal, and attatching the
pin to the same, so as to project through the Knob for the purpose of actuating the
slide as described, without the assistance of any implement.
Second, making the Slide and Spring with an elongated narrow strip, for effecting
the same object as the pin above described.
