To all Iwhom. t 'may concern:
Be it known that I, GEORGE M.'Knnriiuvnn, the' `county of Fulton have invented an Imand State of Illinois, t
and Gage, of which proved'. Combined Level :the following is al specification.
y This invention isfin lthe' nature of an improved tool or `appliance t-hat is more es- 'peciallyk designed for use .when building forms -for concrete walks, driveways, feed floors, etc., and also for placing nailers l in building headers over doors and windows.
Primarily, my invention has for its object to provide 'a tool or appliance-of the character stated of a simple and economical construction, that can be conveniently hanadjusted for use and which efserves its intended purposes.
inafter appear, my invention consists 1n ment of the parts hereinafter explained, specifically pointed out in `the appended claims and illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view of myinvention, the same building a concrete walk. Fig. 2 is a 'lo-ngitudinal section of my improved tool `or appliance. Fig. 3 is a cross `section ofthe same on the line 3-3 on Fi .-2. Fig. 4 is view of one o the extensible or gage members. Fig.5 is a 'detail view of a modified arrangement for joining the clamping means with the extensible or gage members. Fig. 6 is a crotss section thereof.
In the practical application of my invention, I use a leveling tool that comprises vthe conventional form of body or stock 1,
longitudinal groove 6. l
lmembers 8, one
having a leveling bulb 2 in the upper face and the vertically, disposed bulbs 3 in the opposite ends thereof, a carrying handle 4 being disposed in the top edge of the body that s'traddles the transverse sightk grooves 5, for the leveling bulb 2, as shown. The under or lower edge of the bod :specification of Letters Patent. Application led February 4, 1913. Serial No. 746,194.
being shown in use in' connection with the drawing, the operation and the advantages of my in- 1 has a. longitudinal groove Gand in whic play the, of the extensible or gage:
"laying 0H concrete walks,
o oMBiNnn Lavar'. AND GAGE.
the members 8 are of metal, are preferably Patented sept. ssa-'1913. t
integral with the said members and when the members 8 are of wood are nailed to the said members 8. Each gage member 8 also has a endent lug 11 that serves to locate the width points for placing the side boards or forms for the walk, see Fig. 1. I
12-.12 designate hangers, one for each gage or extensible member 8, and they'jfit Vloosely on the said members; The hangers 12 fit intosockets 13 in the under edge of the level body 1, as is clearly shown in4 Fig. 3, by'reference to which it will be also noticed the socket 13 merges with the lower end l of a vertical opening 14 that extends `through the upper edge of the levelV body, it being provided to receive the lclamping rod 15 that pivotally connects'witli the stirrup 12, and has its upper 'endthreaded to receive the winged clamping nut 1 6.
An indicator 17 is attached toeach inember 8 to travel over an indicator. or scale plate 18 secured on the face of the level body, the/figures of which, are stepped off from the center.A in both directions, and indicate the diierent walk widths, it, being understood that whenthe two members 8 are set to the position shown in Fig. 1, the distance "across from one lug 11,-to the other lug From fthe 'foregoing'- description, taken Hin vention will be readily understood.
Instead of using the stirrup connection, as
shown in Fig. 3, the clamping rod may be.
it is believed connected to the gage member 8, as shown in Fig. 6. In this form, `the vertical portion of the body of the said member has' short lateral flanges 19, that slide through the hangers or yokes 20, pivotally suspended from the'grod 15. .When this latter form is used, the 'level 'body has guide grooves 2 1 to receive flanges 19.
While my invention has been shown and described as especially adapted for use in stood that the same may alsobe used. for placing nailers in headers over doors or windows.
I desire it underedge of the stockfor clamping the extensible I member in its adjusted positions, themsaid means comprising a screw rod that extends up above the upper edge of the stock, .:a
*nut that engages the rod and the said stock,
ivotally suspended from, the
A mounted in thesaid groove, each of the members having a gage lug at the vouter end,
- meansl operable fromthe `upper ed e of the '20 level bo y for clamping` the extensi le members intheiradjustedpositiom a scale plate on the `said-level,body common to both of the .extensible members and an indicator connectedto each lof the said members and movable over the scaleplate,
3; A combined spirit level `and "gage, comprising the followingelements in combination ;/a stock or body having the usual bubble glasses, a longitudinal groove in its lower edge that extends the full length thereof, a' socketl at each end that bisects lthe said groove and terminates in vertical apertures that open through the to -of the level soclnt of .the bod that takes around their vrespective?'extensi le, member, a screw yrod mounted4 in each-of` the vertical apertures in the stock, said rods beingy pivotallyl-connected withtheir respective hangers and a nutengagmg each screw rod and the' top .edge .ofthe level body. 4.,A combined" level and gage, comprising=a bodyor stock having a groove in its underside, a gage member including a web,
longitudinally slidable in said groove, and a base flange ada ted to contact with the bottom face of sai stock, said gage member being longitudinally extensible from the stock, a hanger shaped to embrace and slidably hold sald .gage member, said stock having la chamber'to receivel said hanger, a bo t pivoted to said hanger and .projecting through said stock, and a nut coperative with said bolt to draw said hanger toward said stock and thereby hold said gage member in its adjusted ositions.
