Improvements in the Construction of Doors, Shutters, and the like,

I. JOSEPH TALL, of View House, Belvoir Road, Lordship Lane, Dulwich, Surrey,
Architect and Consulting Surveyor for Portland Cement Concrete Buildings, do
hereby declare the nature of this invention to be as follows
:-
The object of this invention is to manufacture panel, or other doors, or shutters and
the like also window sashes or sash frames without the usual mortice and tenon, and
in some cases without the aid of glue.
The invention is subject to many modifications and as examples, I cut boards or
timber to the given dimensions for styles, rails, or transverse pieces, and I form holes
through them and insert screw bolts with angled or cheese heads which fit about flush
from one edge or style and have half cut nuts screwed on to said bolts and in hollows
of the opposite style or end, the parts being drawn closely in contact and made very
rigid, or half round or other shape of nuts may be arranged in apertures formed by a
centre bit for tightening the parts together. If panels are employed, the edges may
be chamfered and inserted into grooves of the styles and rails, or cross pieces.
If the cross rails and the styles be grooved, wedges may be used to fill up the gaps.
As another example. I cut the ends of the style and the ends of the cross pieces to
corresponding angles, and these may be plain or grooved and filleted, and I insert a
long screw at about right angles thereto into the solid wood for securing the parts in
close contact.
According to another example, 1 cut the cross rails with end feathers and form
corresponding openings in the styles, so that the projecting pieces of one fit the
hollows of the other like a dovetail but without sharp corners and produced preferably
by a band saw, each part locking itself to the other in a secure manner.
The long
screw, or the screw bolts before spoken of may be employed with this example of
construction.
The invention as described with reference to Doors is applicable to shutters and the
like also to sashes, and sash frames.

Improvements in the Construction of Doors, Shutters, and the like,

1, JOSEPH TALL, of View House, Belvoir Road, Lordship Lane, Dulwich, Surrey,
Architect and Consulting Surveyor for Portland Cement Concrete Buildings, 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:-
The object of this invention is to manufacture panel or other doors, or shutters and
the like, also window sashes, or sash frames without the usual mortice and tenon.
The invention is subject to many modifications and as examples which I show
in the annexed drawings, I cut boards or timber to the given dimensions for styles,
rails, or transverse pieces A, B, C, D, E, and I form holes through them and
insert screw bolts F with angled or cheese heads G which fit about flush from or
recessed in one edge or style A and have half cut nuts H screwed on to said
bolts F and in hollows of the opposite style or end B, as seen in Figure 1, the
F D

page_text: parts being drawn closely in contact and made very rigid; or half round, or other
shape of nuts I may be arranged in apertures formed by a centre bit for tightening
the parts together as shown at Figures 1 and 6. If panels are employed, the
edges may be chamfered and inserted into grooves of the styles and rails, or cross
pieces.
If the cross rails and the styles be grooved, feather tongues or tenons J may be
glued in for giving extra stability to the door.
As another example which I show at Figure 2, I cut the ends of the styles A, B,
and the ends of the cross pieces or tails C, D, to corresponding angles and these may
be plain, as at Figure 2, or grooved and filleted, as at Figure 3, and I insert a long
screw K at about right angles thereto into the solid wood for securing the parts in
close contact.
Screws K may be also inserted into the styles and rail, as indicated at Figure 2.
Figure shows this method of construction as applied to a door or window sash rails
having an angled or A shaped top.
According to another example which I show at Figure 5, I cut the cross rails C, D, E,
with dovetails L, L, without sharp corners and form corresponding openings in the
styles A, B, so that the projecting pieces of one fit the hollows of the other and
produced preferably by a band saw, each part locking itself to the other in a secure
manner, screws or wood pins being used, if desired, to assist as indicated at P,
Figure 5. The long screw K, or the screw bolts F before spoken of may be employed
with this example of construction. In this method of preparing panel doors, one
side M of the groove will bo removed and be fixed in position when the door is
made up.
The invention as described with reference to doors, is applicable to shutters and the
like, also to sashes and sash frames. Plngs of wood N may be inserted in the holes to
cover the heads and nuts of the bolts, or screws.
Doors, shutters and the like, also sashes and sash frames constructed according to
my invention, cost less, require less time to manufacture and are not liable to
warp or get out of shape, as is the case with doors etc., as hitherto constructed.
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. The improvements in the construction of doors, shutters, and the like, also sashes
and sash frames, as described and shown by the annexed drawings.
2. The employment of screw bolts F, or screws K in the manner indicated at
Figures 1, 2, 3, 4 and 6 of the annexed drawings for the purpose set forth.
3. Cutting dovetails L, L, without corners on the ends of the cross rails for fitting
in corresponding recesses in the styles as and for the purposes described and as shown
at Figure 5 of the annexed drawings.
