rnurn-rnnssuniu GAGE,
Specification of Letters Patent. Patented Sept. 12, 1911. duplication filed August 25, 1910. Serial No. 578,942.
To all whom it may concern:
Be it known that we, Josnrn Simeon and WILLIAM F. Anunnoxrr, of Syracuse, 1n the county of Onondaga, injthe State of New able indicating mechanism for registering the degree of pressure of the fluid.
The main object is to establish as nearly as possible a direct connection between the movable end of the tubular sector and index finger for the purpose of reducing the number of parts and the cost of manufacturing and at the same time simplifying the assembingo and adjustment.
Another object is to enable the index 1' to be easily and quickly adjusted with to the graduations on the dial without loosening any of the connections be ecu the spring sector and finger thereby maintaining a positive connection and reducing the liability of the index finger becoining displaced when the instrument is once adjusted. i
further object is to enable the entire mechanism exclusive of the use to be assembled as a unit and properly adjusted before being inserted into the said case and to utilizc a portion of the main supporting post for the spring, dial and other operating parts for the reception of a Wrench whereby the entire indicator includingthe case may be readily attached or screwed upon'zr'pressure producing device or other part connccted thereto without liability of oi er straining the case or any part of the mechanism.
A still further object is to secure the dial to the post eccentrically that when inserted in the case it will be self retaining against circumferential displacement.
Utt objects'nnd uses will he brought out in tin ollowing description.
in ire -lis a front J Wings, Fi r on of the indicator. .tfiig.
--2- is 'a similar elevation except that the cap of the case is removed to show the inte ,rior mechanism. Fig. -3 is a rear View of the same device showing a portion of the post,- spring sector and case in section. Fig.
is a side elevation of the interior mechanism showing the case in section. Fig. --5- is an enlarged front elevation of a portion of the interior mechanism showing particularly the connections between the index linger and movable end of the spring sector. Figs. -6- and -7- are sectional views taken respectively on lines 6-6 and 7-7, Fig. 5. Fig. 8- is a side elevation partly in section similar to Fig. -&- showing a modified form of post and attaching nipple secured thereto and projecting through the back of thecase.
This gage is adapted more particularly for indicating the degree of air pressure for pneumatic tires and similar uses and coin prises a main supporting post -1- carrying a spring sector --2- and dial and an index finger -twhich is connected by a link -5- to the free end of the spring sector 2, the entire mechanism thus far described being mounted within a suitable case .-6-.
The post --1- is preferably square in cross section and provided with an integral threaded nipple 7- which together with the adjacent square portion of the post is adapted to beinserted through a square opening -8 extending radially through one side of the case so as to leave one end of the square portion of said post projecting some distance from and beyond the periphery of the case for the reception of a wrench whereby the entire indicator may be readily screwed to a pressure generatornot shown or any attachment thereof. The threaded end of the post provided with a central openingor passage 9-v communicating with one end of the flat tubular spring sector having one end inserted in a groove or slot --;l() in one side of thesquare portion of the post --l--- and rigidly secured therein by soldering or otl'icrwise, the other end he e; closed and. extending around the upper and of the post some distance therefrom and to the opposite side thereof as tobe 'lrce to-evpand-and contract under varying pr lies of the fluid which may enter thc rii The radius of the spring sector --2-- is somewhat less than 5 operating fluid.
The dial 3 is nearly semi-circular and of a radius substantially equal to-that of the interior of the case with Which its periphery is adapted to closely fit when ad:
19 justed for use, said dial being eccentrically secured to the front side of the post 1 by suitable fastening means as a single screw 1l and interposed washer 12' so that when the post or the dial thereon is placed 15 within the ease engagement of the periphery thereof with the interior of the case will prevent rotary ,displacement of the dial thereby assuring proper relations between the dial andindex finger. The object of gothe washer ''12 is to hold the dial clear from the spring sector, and other movable parts lying directly under the same, said dial being provided with-the usual graduations numbered in this instance from zero to 150 degrees and extending through an arc of about 90 degrees concentric with the axis movement of the index finger This index finger is pivoted directly to the front side of the post 1 by a pivotal screw 13. in proximity to the point of securement of the spring-sector 2 so as to travel freely around the dial and is provided with an integral arm 14- see Fig.
6 projecting from the hub thereof and bent or returned upon itself into the form of a I loop. The free end of this arm or loop terminates at one side of the pivotal screw 13- and between said pivotal screw. and
dial and is connected by the link -5- to a 40v bendable arm or extension 16. on the free end of the spring sector 2 thereby form- 'i'nga nearlv direct and positive connection between saidsector and index finger, the link extending in this instance across the arc of movement or near the axis of said index finger so as to operate the finger from its 7 normal position at its zero point at the left along the graduations under fluid-pressure acting upon'the sector. The object in bending t e pendant arm or. extension -14.. of
the index finger into the form of a loop to permit the free end of said arm to beadjusted toward and from the fulcrum or pivot 13 when necessary to properly adjust the index finger with reference to the,
dial, That is, if the index finger does not register with the proper graduation on the dial under predetermined pressure in the spring sector, the arm '14 may be bent or twisted laterally by a. pair of pincers or other suitable tool until the index finger is brought -to the proper graduation. One end of theextension .,16 is inserted into the free end of the tubular sector -2-and is secured spring sector, and a support therefor having the index finger or it may be adjusted latertherein by soldering or otherwise to effectively close or plug this end of the sector, the remaining portion of the arm/{-lfi -is comparatively narrow so it canbemeadily bent by a pair of pincers or simila'ntool for the purpose of additionally adjusting the index finger. That is, it may be adjusted toward and from the free end of the sector to vary the speed of movement or throw of ally with reference to the axis of movement of the finger to bring such finger into regisztration with the proper graduation under a predetermined fluid pressure in the sector.
' In some instances, it may be necessaryor desirable to attach the instrument. at the back to the pressure device or other attachment and in Fig. -8 we have shown the post as made in two sections 20 and. -2l, the section -20- carrying the sec- 35 tor, dial, index finger and other active parts of the device being located within the case -6 and provided with a suitable aperture in the back side thereof for the reception of one end of section 21- which is passed.9 through an opening in the back of the case and secured into the inner post section. The section '-21- is provided with a square portion and also with a hollow threaded nipple, the square portion serving to receive a wrench or similar device whereby the indie cator may be secured upon a pressure devicenot shown. The opposite ends of the link 5- are pivotally connected by suitable screws to the corresponding ends of the ad justing arms 14 and -16- of the index finger 4- and sector -2- respectively.
In the preferred form of our invention shown particularly in Figs. 1,--2- and 3 the postlis secured against the interior of the back of the case by fastening screws 1--- see Fi {L The front of the case is provided wit a suitable eap6-- removably secured thereto by screws -7 and provided with sight opening 22- across which is placed a transparent shield 23, the'sight opening conforming nearly to the sha e of the dial or rather to the are of the gra uations'so that the corresponding end of the index finger and graduations may be. always-visible through the transparent shield. This shield serves to prevent the entrance of dust to the interior of the case through the sight opening and is held in place. by an inner apertured plate -24- which is secured by one or more rivets -25 to the front of the cover.
