RUDOLPH GROSS, OF BRENHAM, TEXAS.
PEDAL ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 701,714, cated June 3, 1902.
Application filed January 16, 1902 Serial No. 89,985, (No model)To cl WhO72 it mr7ay con1cerin1:
Be it known that I, RUDOLPH GROss, a citi-
zen of the United States, residing in Brenham,
in the county of Washington and State of
5 Texas, have invented certain new and use-
ful Improvements in Pedal Attachments, of
which the following is a specification.
This invention relates to an improved at-
tachment for pianos, organs, or other instru-
To ments provided with pedals, said attachment
being designed for the purpose of closing the
openings below the pedals, so as to prevent
mice and other vermin from entering the in-
strument and damaging the same. The at-
15 tachment also acts in the nature of a dust-
protector and an auxiliary spring for the ped-
als, and for these purposes the invention con-
sists of a fiat spring provided with an up-
wardly-bent forward portion having a recess
20 in the end edge thereof for engaging the bot-
tom and sides of the pedal, the spring being
provided with a perforation at the opposite
end and fitted to the under side of the piano-*
casing below the pedal and extending into a
25 recessed portion provided thereat, said up-
wardly-bent end being adapted to close the
pedal-opening, as will be fully described here-
inafter and finally pointed out in the claims.
In the accompanying drawings, Figure 1
Ao represents a front elevation of an upright
piano with my improved pedal attachment in
position thereon. Fig. 2 is a front view of
the pedals, drawn on a larger scale, showing
the attachment employed only on the left
35 hand and the central pedals. Fig. 3 is a ver-
tical transverse section, drawn on a larger
scale, on line 3 3, Fig. 2; and Fig. 4 is a per-
spective view of the spring attachment shown
as detached from the pedal.
40 Similar letters of reference indicate corre-
sponding parts.
Referring to the drawings, A represents
the pedals of a piano, organ, or other pedal
instrument. The pedal - openings a in the
45 casing, through which the pedals project, are
closed by means of my improved attachments
B, each of which consists of a flat spring, the
shank b thereof being seated in the recess a'
at the under side of the casing, as shown in
50 Fig. 3,.said recesses a' being arranged below
the pedals. The front ends b' of the springs
are bent in upward direction and are re-
cessed, so as to fit the bottom and side of the
pedal-shank, as shown clearly in Figs. 3 and
55 4. The front edge of the casing at the re-cesses a' is preferably beveled, so as to con
form to the shape of the spring. The up-
wardly-bent ends of the springs are arranged
to fit tightly over the openings a and prevent
the ingress of dust into the interior of the in- 66
strument as well as keeping out vermin. As
the front end of each spring attachment B
supports a pedal, it serves as an auxiliary
spring for returning the same after it is de-
pressed. The attachment can also be used 65
without the interior spring-actuating means
for the pedals.
The spring attachment is simple and inex-
pensive, forming a valuable and effective
means for protecting the interior of pianos, 70
&c., against damage by dust or by vermin,
and can be used by manufacturers instead
of the usual spring-actuating pedal devices,
if so desired, or it can be readily attached to
pianos which are already in use. 75
Having thus described my invention, I
claim as new and desire to secure by Letters
Patent-
1. A pedal attachment for pianos, consist-
ing of a flat spring having one end upwardly so
bent and recessed at the end edge thereof to
engage the bottom and sides of the pedal-
shank, and having an aperture at its oppo-
site end, substantially as set forth.
2. The combination, with a pedal and a re- 85
cess in the bottom of the casing of an instru-
ment provided with pedals, of a spring hav-
ing a shank which is attached at one end in
said recess and having the up-bent end thereof
retained in contact with the under side of 90
said pedal, substantially as set forth.
3. In a piano having pedal-openings in the
casing thereof, the combination, with the
pedals, of auxiliary springs for said pedals
arranged below the same and being secured 95
to the under side of said casing, the outer
ends of said springs being bent upwardly
and recessed to engage with said pedals, said
upwardly-bent ends being arranged exteriorly
of and adjacent the front of said casing and Too
covering said pedal-openings, substantially
as set forth.
In testimony that I claim the foregoing as
my invention I have signed my name in pres-
ence of two subscribing witnesses.
