GAGE.
Specification of Letters Patent.
Patented June '7, 1921.
2 Application filed November 22,1920. Serial No. 425,900.
(FILED UNDER THE ACT OF MARCH 3, 1883, 22 STAT. L, 625.)
To all whom. it may concern:
Be it known that I, FRANK. ROBERT McGoWAN, a citizen of the United. States, and an oflicer of the Government employed in the Bureau of Standards, Department of Commerce, Washin ton, D. C., and residing at 36 Varney St., fowell in the county of Middlesexand State of Massachusetts, have invented a new and useful Gage, of which the following is a specification.
The improvement, if patented, may be used by the Government, or any of its officers or employees in the prosecution of work for the Government or by any other person in the United States without the payment of an royalty thereon. 1
y invention relates to improvements m a gage for determining the tautness of aeronautical fabrics; and the objects of my improvement are first to construct an instrument whose weight will not affect the ultimate readings; second, to construct an 1nstrument that can be readily adjusted on the specimens; and third, means of supporting and applying weights for the determinations.
I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure l is a vertical section of the entlre machine; Fig. 2 a plan view of the machine; Fig. 3, a rear view of a Randall & Stlckney dial showing the mechanism of the feeler with its transverse movement mdicatlng means; Fig. 4, a vertical view of three weights,'F, F, and F which are placed on plate C Fig. 5, a vertical section of a part t of the machine on the line 5, 5, Fig. 1.
Similar numerals refer to similar parts throughoutthe several views.
The bar A has on its lower side near one end a singular rib a, and near the other end two longitudinal ribs a a the three ribs together affording a three-point support for the bar. A feeler C furnishes means whereby said feeler is mounted at the medial portion of the bar for movement transversely thereof. The movement of the indicating means is controlledby the feeler, position of the feeler for maximummovement being attained by adjusting screw 0, which is part of the convex contact polnt C of the feeler.
The lock nut G, tightens against the enlarged portion of the feeler C, and a disk C serves a support for weights F, F,,-
B is a dial for indicating the transverse movement of the feeler C through the gears b, 6,, b b and the pointers 6 and 6,. The spring arm supports E E are used for holding,the weight D which has an opening d, through which the feeler passes, affording a means of interchangeable connection to either the feeler on C or the support D by the special circular groove d; The opening a, in the bar a is a means by which one or both hands can be applied in adjusting gage in position so that the feeler the numbers a, the longitudinal ribs can be placed in the center of the span.
1 am aware that prior to my invention dials have been made whereby the indicating means for the transverse movement of the feeler have been made. I'also wish to state that no patent is requested for the indicating dial. I therefore do not claim such a combination broadly.
I claim:
1. A gage for determining the tautness of aeronautical fabrics comprising a bar having on its lower side near one end a single longitudinal rib and near the other end two longitudinal ribs, the three ribs together affording a three point support for the bar; a feeler, means whereby said feeler is mounted at the medial portion of the bar for movement transversely thereof, movement indicating means controlled by the feeler; a weight having an opening through which the feeler passes and means whereby the 7 weight may be connected interchangeably to either the feeler or the support.
2. A gage for determining the tautness of aeronautical fabrics comprising a bar having on its lower side adjacent to its ends respectively offset contact members; a feeler, means whereby said feeler is mounted at the medial portion of the bar for movement transversely thereof, movement indicating means controlled by the feeler; a fixed weight having an opening through which the feeler passes and means whereby the weight may be connected interchangeably to either the feeler or the support.
3. A gage for determining the tautness of aeronautical fabrics comprising a bar having on its lower side adjacent to its ends respectively offset contact members; a feeler, means whereby said feeler is mounted at the me dial portion of the bar for movement mdlcatlng means controlled by the feeler,
having at its lower end a contact disk provided witha convex lower surface; a fixed weight having an opening through which the feeler passes and means whereby the weight may be connected interchangeably to elther the feeler or the support.
4, A-gage for determiningthe tautness of aeronautical fabrics comprislng a bar having on its lower side adjacent its ends respectively offset contact members; a feeler, means whereby said feeler' is mounted at the medial portion of the bar for movement transversely thereof, movement indicating means controlled by the feeler, the feeler being provided at its upper end with a weight receiving disk; a fixed weight having an opening through which the lower end of the feeler passes and means whereby the weight may be connected interchangeably to either the feeler or the support.
5. A gage for determining the tautness of aeronautical fabrics comprising a bar having on its lower side and near its ends re spectively longitudinal contact ribs; a feeler, means whereby said feeler is mounted at the medial portion of the bar, movement indicating means controlled by the feeler and means whereby weights may be mounted on the feeler; the bar being provided with scales adjacent its contact ribs; the gradua- "tions of the scales being numbered to correspond with the distances from the center point of the bar.
6. A gage for determining the tautness of aeronautical fabrics comprising a bar having on its lower side longitudinal contact ribs; a feeler, means whereby said feeler is mounted at the medial portion of the bar for movement transversely thereof, movement indicating Ymeans controlled by the feeler, the feeler including a contact member having a convex contact surface and having screw-thread engagement with the lower extremity" of the feeler body, whereby the contact member is adjustable with relation to said body, and means whereby weights may be mounted on the feeler.
