page_text: I, JOSEPH SHAW, of Pond Cottage, Hove Edge, Lightcliffe, in the County of York,
Estate Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus employed for face boring horizontal or angled
shot holes for blasting operations in quarries and mines, and consists of an improved
portable stand for supporting the screw or worm shaft employed for turning the boring
bit or auger.
According to this invention, I employ an iron bed plate, preferably square or
rectangular in shape, and on the underside of which may be one or more spikes or
pointed dowels. On the upper surface of the said plate is a standard of bridge or other
convenient form and provided at its front edges with slots or recesses for purpose of
receiving side studs or pins projecting from the clutch. Screwed nut or other like
appliance (hereinafter referred to as "screw box") in and through which the screw
shaft works for propelling the boring bit or auger.
The apparatus is used and operates as follows:-When the bed plate is placed in
position opposite the face of the material in which a shot hole is to be bored, the
spike or spikes on its under side penetrate more or less the material on which it is
placed and so assist in securing the bed plate. The screw box is then to be put in
position in its holding standard, which is accomplished by placing it within the
bridge piece, the side studs of the screw box being received in two opposite slots of
the bridge higher or lower according to the height or level the bore hole it required
to be. When the boring bit is in position and the screw shaft is turned by ratchet
lever or other means of rotating the screw shaft and boring bit, the back pressure or
thrust is on the bridge and bed plate which by reason of the frictional contact of the
under side of the bed plate further assisted by the spike or spikes thereunder
effectually prevent slipping or sliding back of the bed plate and bridge, and the
boring is effected, there being no fixing of the apparatus requisite by means of screws
and centres as in vertical boring, nor trains as heretofore employed in face boring, all
that is necessary
to place the portable bed plate and standard in position and it is
at once ready to receive the boring tackle, and is self holding as against the back
thrust.
The side studs of the screw box may be made longer than required for supporting
the box in the bridge so as to serve as a convenient means for rapidly returning the
nut or screw box to the starting end of the screwed shaft.

page_text: I, JOSEPH SHAW, of Pond Cottage, Hove Edge, Lightcliffe, in the County of York,
Estate Agent, 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 apparatus employed for face boring horizontal or angled
shot holes for blasting operations in quarries and mines, and consists of an improved
portable stand for supporting the screw or worm shaft employed for turning the
boring bit or auger.
According to this invention I employ an iron bed plate preferably square or
rectangular in shape and on the under side of which may be one or more spikes
or pointed dowels. On the upper surface of the said plate is a standard of bridge or
other convenient form and provided at its front edges with slots or recesses for
purpose of receiving side studs or pins projecting from the clutch screwed nut or
other like appliance (hereinafter referred to as the "screw box") in and through
which the screw shaft for propelling the boring bit or auger works.
Such being the nature and object of my said invention, the following is a complete
description of same, reference being had to the annexed drawings, in which :-
Fig. 1 is a side elevation of the improved portable stand for face boring shewing
also the screw shaft and part of the boring bit or auger.
Fig. 2 is a front elevation of Fig 1.
According to this invention employ an iron bed plate 1 preferably square or
rectangular in shape and on the underside and near the front of which is a spike or
pointed dowel 2. On the upper surface of the said plate 1 is a standard 3 of bridge
or other convenient form and provided at its front edges with slots or recesses 4-4
for purpose of receiving the side studs or pins 5-5 projecting from the clutch, screwed
nut or other like appliance 6 (hereinafter referred to as the "screw box") in and
through which the screw shaft 7 for propelling the boring bit or auger 8 works.
The apparatus is used and operates as follows:-When the bed plate 1 is placed in
position opposite the face of the material in which a shot hole is to be bored, the
spike or spikes 2 on its under side penetrate more or less the material on which it is
placed and so assist in securing the bed plate 1. The screw box 6 is then to be put
in position in its holding standard 3 which is accomplished by placing it within the
bridge piece, the side studs 5-5 of the screw box 6 being received in two opposite
slots 44 of the bridge higher or lower according to the height or level the bore hole
is required to be made. When the boring bit 8 is in position and the screw shaft 7:
is turned by ratchet lever or other usual means of rotating the screw shaft 7 and boring
bit 8, the back pressure or thrust is on the bridge 3 and bed plate 1 which by reason
of the frictional contact of the under side of the bed plate I, further assisted by the
spike or spikes 1 thereunder, effectually prevents slipping or sliding back of the bed
plate 1 and bridge 3, and the boring is effected, there being no fixing of the apparatus 4
by means of screws and centres as is requisite in vertical boring, nor trams as hereto-
fore employed in face boring: all that is necessary is to place the portable bed plate 1
and standard in position and it is at once ready to receive the boring tackle, and is
self holding as against the back thrust.
The side studs 5-5 of the screw box 6 may be made longer than required for 4
supporting the box 6 in the bridge 3, so as to serve as a convenient means for rapidly
returning the nut or screw hox 6 to the starting end of the screwed shaft 7 by
removing the latter and the box 6 from the bridge 3 and then by means of the
studs 5-5 rapidly rotating the box 6.

page_text: One or more spikes 2 may be employed, but in practise I have found one spike to
be sufficient when placed in about the position indicated in the drawings.
The standard or bridge 3 may be at right angles to the bed plate 1 as shewn,
or slightly inclined forward or towards the front at the top.
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:-
(1) The general construction, arrangement, and combination of parts constituting
the improved boring machine, as and for the purpose herein described, and
substantially as illustrated by the accompanying drawings.
(2) The bed plate 1 with spike or spikes 2 on its underside, the standard or
bridge 3 with recesses or slots 4-4, all in combination as and for the purpose herein
described and substantially as illustrated by the drawings annexed hereto.
