Only a single number appears, so there is no confusion' or uncertainty as to the pressure. When the gage is removed, the piston dropsback, forced by the spring, but the indicator tube'remains at its highest posir'tion, held there by the spring 25 and the pressure can be read without discomfort.
To bring the'indicator tube back into normal position, the button 17 vis pressed inwardly, thus releasing the pressure of the spring andthe barrel is. slid down by pressing downwardly'onl thebutton. It, is not essential to have thebutton on the spring member, butit makes a much better con-V struction.
'In my device, the pressuecan be read at any-time without stooping intoY an uncom- Afortable position and the indicator shows the-' pressure until the `indicator` tubeis manually slid back.
'By turning in the lip 27, I make it iml possible to force out the piston head or washer,vno matter how vhard the pressure applied. l d By the use of the open window with a .c single number exposed, I protect the indicator fr'om wear and increase its accuracy.l

Iclaim: 1. A tire gage coJmprisingfan outer tubular shell, a cap fitting over the top thereof, a piston head :[itted within said shell and providedwith a piston rod, fa coiled springn surrounding the rod and bearing at one end off the cap and at the other end on'the piston, an ,indicator memberloosely seated on" the piston head and yslidable within said shell, said member bearing a pressure indieating scale, means below said piston head 'adapted to establish communication between the interior of the shell-and the interior of unseating means, a portion of said indicator -member being sprung outwardly and adapt- `a pneumatic tire and including tire valve ed to bear against the interior of said shell to hold said member in-indicating position j afterr said gage is removed from the tire valve, there being a small opening through said shell so positioned that the indicated pressure may be read, and means for returning said indicating member at will.
2. A tire gage comprising an outer tubular shell having a slot extending longitudinally at its upper portion, a cap iitting over the top thereof, a pistonhead fitted within said shell and provided with a piston rod, -a coiled spring' surrounding the rod and bearing at one end on the cap andv at the other end on the piston, an indicator member loosely seated on the piston head and slidable within said shell, said memberbearing a pressure indicating scale, means below said piston head adapte to establish communicationy between thev interior of the shell and the interior of a pneumatic tire and includl ing tire valve unseating means, a portion of said indicator member being sprung outwardly and adapted to bear 'against the inmanually returned to its non-registering position after a reading.
In witness whereof, I fhave hereunto sub- A. E. POLLOOK.
