TROY HOIONAT DI BUITIVATION.
Improvements in Bench Planes.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a communi-
cation to me from abroad by Thomas Bartholomew, of Danville, Pennsylvania,
U.S.A. Inventor,) to be as follows:-
This invention relates to a new and useful improvement in bench planes, and it
consists in an attachment to the planes for facilitating the holding of the plane when
being used.
By this invention the plane is provided with a hand attachment which consists of
a hollow piece of wood or metal which is approximately of triangular form. One
of its edges is adapted to rest against the rear of the plane-iron when one of its
other edges rests upon the plane-stock, and the remaining third or rear edge is
curved to adapt itself to the hand of the user. The edge which rests upon the
plane-stock is formed integral with a base, whereby the attachment may be secured
to the stock by screws or other means. A cushion is located between the base and
the stock, in such manner as to tilt the attachment, and prevent breakage thereof
by striking the plane stock to loosen the iron.
By the use of this invention the plane can be more firmly held by the operator,
and the hands are less likely to become blistered than by using a plane without the
hand attachment.

COMPLETE SPECIFICATION.
Improvements in Bench Planes.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Thomas Bartholomew, of Danville, Pennsylvania,
U.S.A. Inventor,) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :--
My invention relates to improvements in bench-plane attachments.
The object of the invention is to provide an improved attachment for planes. to
fit into the angle between the plane-iron and thereby protect the hand from the
sharp edges of the iron.
These objects are accomplished by my invention and it consists in certain novel
features of construction and in combinations of parts more fully described hereinafter
and particularly pointed out in the claims.
Referring to the accompanying drawings
Fig. 1 is a side elevation of a bench-plane provided with the present attachment
or hand-guard.
Fig. 2 is a rear end view of the same.
Fig. 3 is a detail perspective of the hand-guard.
Fig. 4 is a detail bottom plan of the same.
Fig. 5 is a detail of the cushion for the guard.
Fig. 6 is a section or plane on line x x Fig. 2.
In the drawings the reference letter a indicates the body or stock of a plane
provided with a plane iron 6 and a wedge c, as usual.

page_text: When using bench-planes of the characteristics shown the stock is grasped by
the right hand just in rear of the plane-iron, and as the plane is reciprocated the
tender portions of the hand between the thumb and first finger press and rub against
the sharp edges of the iron and bit, and are thereby injured, blistered, and rendered
exceedingly sore and uncomfortable; and, further, it is difficult to obtain a good
hold of the stock of the plane. In order to obviate these disadvantages a hand-
guard d is secured and fitted in the angle between the upper face of the stock and
the iron. This guard is hollow and formed integral of cast or sheet metal provided
with the flat base e formed by an inwardly extending flange having opposite trans-
verse apertures to receive the securing screws, from which base the guard extends
upwardly and rearwardly and is rounded at its top, the edges thereof fitting against
the rear face of the iron, and inclined upwardly at an acute angle equal to the angle of
the iron. The rear outer rounded side of the guard is formed so as to fit in the space
between the thumb and first finger, and on the right hand side this guard is provided
with a depression h to receive the main thumb-joint. The rear or heel portion of the
base of the guard is provided in its under face with a depression or socket i to receive
and hold the cushion of leather, or other suitable substance fitting between the guard
and plane stock, and the under face of the base is provided with a pair of down-
wardly projecting lugs at opposite ends of the said socket. These lugs serve
as rests or feet and prevent the guard from being screwed down too tightly or
unevenly, and also serve as guards to prevent the cushion being scraped or knocked
from its place. The object of this leather cushion is to give the guard an elastic
bearing, raise it up, and prevent it from breaking from the jar caused by striking
the plane to loosen the plane-iron. The cushion can be secured in its socket by
any suitable material, such as glue, etc. Of course, it is understood that if the
wedge e is placed beneath the bit or iron the guard will fit beneath the same in a
like manner.
The great utility and advantages of this article are obvious and well understood,
and the article can be manufactured and sold and applied to any plane.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. As a new article of manufacture, the herein-described hollow hand-guard for
bench-planes, formed integral and consisting of a base to fit on the upper face of
the plane-stock, provided with apertures for the securing-screws, and with a socket
and feet on its under face, for the purpose set forth, and an upwardly and rear-
wardly inclined portion to fit against the rear side of the plane-iron formed on its
rear side to fit the hand, substantially as described.
2. The herein-described hand-guard for planes formed integral consisting of a
base to fit on and be secured to the stock, and provided with one or more feet to
bear on the stock, and an upwardly extending portion inclined rearwardly and
rounded on its outer side to fit the hand, substantially as described.
3. The hercin-described hand-guard for planes consisting of a base having
perforations for the securing screws, and provided near its heel with a socket to
receive a cushion, and with feet located on opposite sides of said socket, and the
portion extending upwardly from the base having inclined edges and formed at its
rear side to fit the hand, substantially as described.
4. The combination, with a plane-stock and plane-iron, of a hand-guard secured
and fitted in the angle between the upper face of the stock and the plane-iron, and
rounded on its outer side to fit the hand, and a cushion interposed between the
stock and said guard, substantially as described.
5. The combination, of a plane with a hollow integral metal hand-guard thereon
having a base secured to the stock, and a cushion located between said base and
stock to tilt said guard and prevent breakage of the guard by striking the plane-
stock, substantially as described.

page_text: 6. In a plane, the combination, of a stock, with a hand-guard formed hollow and
integral, and having a base secured to the upper face of the stock, a portion
rounded at its rear and extending upwardly and fitted against the rear face of the
plane-iron, and a cushion interposed between the base of said guard and stock, and
resting in a socket, for the purpose set forth.
