1 Claim.
This invention relates to sound-producing devices such as horns, whistles, etc., and especially to a quick-change whistle combination; that is, a very simple combination of three pieces that may be very quickly and easily united by their inherent properties including contraction and expansion of a rubber strip or strip of other resilient and resonant material that is stretched, tensioned, and expanded between the outer and inner tube-sections for co-operation therewith to produce whistling sounds when air or other gas is forced through said tube-sections past said resilient strip.
One object of this invention is to provide a whistle that can be quickly assembled by any person of ordinary ability without the use of any tools or extrinsic fastening means, and can be quickly disassembled and. reassembled with the resilient strip under alternately higher and lower tensions so as to change the tone or pitch of the sounds with each reassembling operation.
Another object is to provide a whistle in which all parts are kept united by their inherent prop erties, including the pressure and clamping effect of the resilient strip between the non-resilient inner and outer members.
Other objects and important features are pointed out or implied in the following details of description, in connection with the accompanying drawings in which:
Fig. 1 is a side elevation of a whistle made according to this invention.
Fig. 2 is an outer end View, and a view of the interior of the whistle.
Fig. 3 is a sectional view taken in the plane of the axis, the broken lines showing extent of retraction of the free ends of the resilient strip after being released by the thumb and finger of the user after having stretched the intermediate part of the strip across the concaved or inwardly converged end of the inner tube-sections and has inserted it in the larger and outer tube-section.
Referring to these drawings in detail, wherein, similar reference characters represent similar parts in the several views, the invention is described in detail as follows:
The whistle comprises the combination of an outer member 5 having an opening 50 therethrough, an inner member 6 having an opening 60 therethrough and having one end 6e slightly smaller in cross section than the cross-section of the first said opening, and a resilient and resonant strip i having its intermediate part 12' normally stretched across said end and opening of the inner member and disposed therewith in said opening of the outer member and having opposite portions 1e inherently expanded against said inner and outer members with pressure sufiicient to removably and adjustably secure all three elements of the whistle together in cooperative relation.
The inner member 6 and resilient strip 1 have end-portions normally protruding from the outer member 5 to provide manipulative elements, so they can be grasped by a hand of a user for removal from or adjustment in the outer member; and so the resilient strip can be grasped, pulled and tensioned to various degrees, thereby to obtain various pitches of tone, also to quickly change from a torn or deteriorated resilient strip to a newer or more desirable strip.
The inclined inner end is shown at 6i, and permits air to pass by the intermediate portion of said resonant strip, even if the latter is wider than the opening it crosses.
The invention also includes the method of forming a whistle by uniting the outer member 5 and inner member 6 by the inherent resiliency of the strip 1 as follows: First, stretching said strip across said opening and along opposite sides of said end of the inner member, with a thumb and finger holding end portions 1h of said strip pressed against the member 6 to keep the intermediate part longitudinally stretched and laterally thinned while inserting said end of said intermediate part of the strip in said outer member, and releasing said end portions to permit said intermediate portions to laterally expand or thicken between and against said inner and outer members.
I have no intention to limit my patent protection to the precise details of explanation, description and disclosure of the drawings, for the invention is susceptible of numerous changes within the scope of the inventive ideas as implied and claimed.
My invention is claimed as follows:
In a whistle or the like, the combination of an outer member having an opening therethrough, an inner member having an opening therethrough and having an insert-end slightly smaller in cross-section than the cross-section of the first said opening and being normally disposed therein, and a resilient and resonant strip having its middle part normally tensioned across said insert-end and opening of said inner member and disposed therewith in said opening of the outer member and having opposite portions inherently expanded against and between said inner and outer members with pressure sufli- 4 REFERENCES CITED The following references are of record in the file of this patent:
