Improved Racket Press.
I, FREDERICK THOMAS PROSSER, of No. 200, Pentonville Road, in the County of
Middlesex, Racket Manufacturer, do hereby declare the nature of this invention to be
as follows:-
:—
My invention relates to improvements in racket presses, and consists in a novel and
economical arrangement of two sets of cross bars of wood, or other suitable material.
Each set is of the shape of a letter H, and the two are adapted to embrace the frame
of the racket between them, the middle limbs of the H lying along the centre line of
the racket. The two sets of cross bars are drawn together by a pair of screws passed
through the racket. These screws are fixed in the cross bars at the intersections of
the sides and cross piece of each set.

COMPLETE SPECIFICATION.
Improved Racket Press.
I, FREDERICK THOMAS PROSSER, of No. 200, Pentonville Road, in the County of
Middlesex, Racket Manufacturer, 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
My invention relates to improvements in racket presses, and consists in a novel
and economical arrangement of two sets of cross bars of wood, or other suitable
material.
Each set is of the shape of a letter H, and the two are adapted to embrace the
frame of the racket between them, the middle limbs of the H lying along the centro
line of the racket. The two sets of cross bars are drawn together by a pair of screws
passed through the racket. These screws are fixed in the cross bars at the intersections
of the sides and cross piece of each set.
In order that my invention, and the means by which the same is to be carried into
practical effect, may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying figures which are to be taken as part of
this Specification and read therewith.
Fig. 1 is a plan.
Fig. 2 is a side elevation.
A is the frame of the racket, shewn as embraced, or rather squeezed tight and flat,
beyond the possibility of becoming warped, between the two sets of cross bars or Hes
above mentioned.
Bare the middle limbs. These lie along the centre line of the racket on the
respective sides thereof.
C, C are the sides of each H, both rigidly connected to the respective middle limb B;
and it is the two pairs of sides which are the operative parts of my invention as far as
contacting with the racket-frame is concerned.
D, 1) are the pressing screws. These may be of the usual sash screw construction
and I have chosen this type of screw for illustration because of its simplicity. Their
respective nuts d, d, are fixed to one of the middle limbs B, both preferably to the
same limb.

page_text: A racket press constructed according to my invention is applied to the racket
as follows:
The screws D, D, are unscrewed from their nuts, and the two sets are placed on the
respective sides of the racket, one exactly opposite to the other as illustrated in Fig. 2;
care being taken that the screw-holes are opposite respective openings in the stringing
to the extent of it being possible to pass them-the screws guided by the screw-
holes in the set through the openings without chafing the stringing. The screws are next
passed through the unnutted set and the stringing, and screwed into their respective
nuts, until the frame is in the necessary condition of compression.
My invention does not confine me to the exact type of pressing screw illustrated.
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 combination of a pair of Hes and pressing screws, as set forth.
2. The combination of racket frame, two pairs of sides adapted to be mutually
approached by screws, the members of each pair being rigidly connected together in
the same plane.
