A vim/ ron EDWARD B. IVOWOS/EL 8K! I I E. B; NOWOSIELSKI RECEIVER HEADBAND Filed A ril 12 1922 Patented Nov. 10, 1925.
EDWARD B. NOWOSIELSKI, OF BLOOMFIELD, NEW JERSEY, ASSIGNOR- TO SPLITDORF ELECTRICAL COMPANY, OF NEWARK, NEW JERSEY.
Application filed April 12, 1922. Serial No. 551,874.
To all whom it may concern:
Be it known that I, EDWARD B. Nowosmn- SKI, a citizen of the United States, residing'at Bloomfield, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Receiver Headbands, of which the following is a description, reference being had to the escort. panying drawing and to the figures ofreference marked thereon. r
This reference relates to headbands for holding receivers which may be used for telephone or radio work; that is to say the band may be adapted to takea single receiver or two receivers, but as illustrated herein it is arranged to take a pair of receivers.
The principal object of my invention is to provide a headband which is very simple and inexpensive, but which will perform all the functions of a more expensive headband.
In the drawings. I
Figure 1 illustrates a perspective view of the headband with one receiver mounted thereon; V
Figure 2 is a partial sectional view through the band and receiver back; while Figure 3 is a section on the line 3-3 of Fig. 1. I
The band is of a single piece preferably of metal having considerable resiliency. The band has its ends bent inwardly at 1. The bent ends have holes 2 therein and leading from the holes 2 is an elongated slot 3 which in width is appreciably less than the diameter of the hole'2. The back a of the receiver has a stud 5 fastened thereto, and as shown in Fig. 2 it is integral therewith, but may be fastened to the receiver back in any suitable manner as by Welding or riveting, etc. The head of the stud 5 is slightly smaller than the hole 2 so that it will pass through thechole, after which the receiver is moved along the elongated slot which is a trifle wider than the reduced portion 6 of the stud 5. The material containing the elongated slot 3 is bowed as indicated in Fig. 3 obtained between the receiver back t and the head of the stud 5, whereby the receiver is securely held in any adjusted position. This arrangement provides an adjustment which is very rapidly secured and hence makes it easy for an operator to adjust the headband and the receiver in position for use.
The band itself is split as indicated at 7 from a point near the bend 1 to the corresponding bend on the other side or end of the band. The two parts of the band 8 and 9 are then spread so as to provide a substantial seat for the band on the users head. After the band has been'constructed as described it may be plated or covered to suit requirements.
The receiver referred to herein is the same as that shown and described in my application, Serial No. 551,873 filed April 12, 1922, but since the details-0f the receiver per se form no part of this invention no description of the same is necessary in this application.'
Having thus described my invention what I claim is: l i
In a device of the class described, a single piece head band having its ends bent inwardly andcbeing split from a point near one. bent end to the other bent end and the split portion being spread for the purpose ing of, a hole and an elongated slotof less 2 width than the diameter of the hole, leading so that a spring grip is described, said ends having means consist
