COMPLETE SPECIFICATION.
New or Improved Cleaners or Scrapers for Pneumatic Tires.
I, WILLIAM GLASGOW, Electrician, of No. 34, Monroe Street, in Chicago,
County of Cook and State of Illinois, United States of America, 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 present invention relates to that class of tire cleaners or scrapers that are
employed to remove the accumulated mud and dirt from the pneumatic tires of
bicycles, etc.
The object of the present invention being to provide, a simple, convenient and
efficient appliance for such uses, in which the parts when not required for use are
adapted to fold or move together, in a very compact manner, and enable the
appliance to be carried conveniently in the pocket of the user, all as will herein-
after more fully appear and be more particularly pointed out in the claims.
I attain such object by the construction and arrangement of parts, illustrated
in the accompanying drawings, in which:
Figure 1, is a side elevation of one form of my present invention, the parts
being shown in their open position ready for use.
Figure 2, a sectional elevation of the same, showing the parts in a closed
condition.
Figure 3, an end elevation of the same.
Figure 4, a side elevation with parts in section of a modified form of the
appliance, the parts being shown in a closed condition.
Figure 5, a similar view of the same in an open condition.
Figure 6, a side elevation of another modified form of the appliance, the parts
being shown in a closed position in dotted lines, and in an open position in full
lines.
Figure 7, a detail broken view of part of the spring for holding the auxiliary
blade in position in Fig. 6.
Figure 8, a detail section of the same and parts adjacent thereto at line x-x,
Figure 6.
Figure 9, an end elevation of the same.
Figure 10, a sectional elevation of another modified form of the present
appliance, the parts being shown in a closed condition in full lines, and in an
open position in dotted lines.
Similar numerals of reference indicate like parts in the several views.
As represented in the drawings the present invention comprises a body portion
or haft 1, 1, 1, 111, and one or more cleaning blades 2, 21, 21, 2111 and 3, 31,
as shown in the different figures of the drawing, that are secured to said body
portion so as to be capable of moving into the same, when not required for use,
and thereby render the appliance very compact, and capable of convenient
carriage in the pocket, etc. of the user.
The main cleaning blade 2, 21, etc. will be a crescent shape, the concavity
thereof being adapted to fit the curved exterior of pneumatic tires, and afford
means for the rapid and ready removal of mud, etc. therefrom.

page_text: The attachment between the end or shank 4, of such blade and the haft or
body 1, being either a pivotal one, as shown in Figures 1, 2, 3, 4, 5, 6, 7, 8
and 9, or a sliding one as shown in Figure 10; 5, 51, 51, 51, are springs resting
against non-circular portions of the cleaning blade shank, and which are adapted
to hold the cleaning blade in a somewhat rigid manner in a closed or open con-
dition, in manner similar to an ordinary pocket knife.
The supplementary cleaning blade 3, 31, will usually be of a tapering or
pointed nature as shown, so as to be capable of ready and convenient use in re-
moving mud and dirt from recesses in the wheel rim, etc.; and such blade will
have attachment to the main body or haft 1, 1', etc. in a manner substantially
similar to that described in connection with the main crescent shaped cleaning
blade 2, 21 etc. such attachment being either a pivotal one as shown in
Figures 1, 2, 6, 7 and 8, or a sliding one, as shown in Figure 10; 6, 61, 61,
6 are springs resting against non-circular portions of the shank of said
blade 3, 3, and which are adapted to hold such blade in a rigid manner in its
closed or open condition.
In the present invention the respective cleaning blades 2, 21, etc. and 3, 31,
will be connected at opposite edges of the main body or haft 1, 1, etc. and will
move in and be housed in such opposite edges, and when opened for use will pro-
ject in opposite directions from said body or haft, as shown.
In use the haft or body 1, 1', etc. may be recessed out or otherwise formed to
constitute a receptacle for matches etc. but such feature forms no part of the pre-
sent invention.
I am aware that prior to my invention, foot hooks for horses have been formed
with a pointed and semi-circular shaped hook, pivoted to a handle portion,
so as to fold together more compactly; also that pocket knives have been formed
with a wire cutting blade, oval on top and concaved on its under side and pro-
vided with a sharp cutting edge, the end being sharply curved so as to provide
against the possibility of the same slipping when being placed under a wire; 1
therefore make no claim to either of such constructions broadly.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is: :-
1st. A pneumatic tire cleaner, comprising a haft or body portion, and a clean-
ing blade having a crescent form, the concaved scraping edge of which is formed
to fit the curved exterior of a pneumatic tire connected thereto and adapted to
move into the haft when not required for use, the concaved cleaning edge of the
crescent shaped blade being of a blunted nature and the face edge of the same
being of a rounded nature, so as to avoid accidental cutting or puncture of the
pneumatic tire, substantially as described.
2nd. A pneumatic tire cleaner, comprising in combination, a haft or body
portion, a crescent shaped cleaning blade, the concaved scraping edge of which
is formed to fit the curved exterior of a pneumatic tire, and a tapering or pointed
blade, both connected to the haft at opposite ends thereof and adapted to move
into said haft when not required for use, the concaved cleaning edge of the cres-
cent shaped blade being of a blunted nature, and the free end of the same, being
of a rounded nature, so as to avoid accidental cutting or puncture of the pneumatic
tire, substantially as described.
3rd. A pneumatic tire cleaner, comprising in combination, a haft or body por-
tion, a crescent shaped cleaning blade, the concaved scraping edge of which is
formed to fit the curved exterior of a pneumatic tire having a non-circular shank,
and a spring attached to the haft and having engagement against said non-
circular shank to hold the cleaning blade in an open and closed condition, the con-
caved cleaning edge of the crescent shaped blade being of a blunted nature, and
the free end of the same being of a rounded nature, so as to avoid accidental
cutting or puncture of the pneumatic tire, substantially as set forth.

page_text: 4th. A pneumatic tire cleaner, comprising in combination, a haft or body por-
tion a crescent shaped cleaning blade, a tapering or pointed blade, both connected
to the haft at opposite ends thereof, and adapted to move into said haft when not
required for use, and springs attached to the haft and having engagement against
non-circular parts of the blades to hold the same in their open and closed con-
ditions, the concaved cleaning edge of the crescent shaped blade being of a
blunted nature, and the free end of the same being of a rounded nature, so as to
avoid accidental cutting or puncture of the pneumatic tire, substantially as set
forth.
