HAMMER GAUGE.

Application filed September 7, 1920.

T 0 all whom it may concern Be it known that I, .PETER F. JOHNsON, a citizen of the United States, residing at Oakland, in the county of Alameda, State 0f California, have invented a new and useful Hammer Gauge, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a hammer gauge, and its object is to provide a gauge which is capable of being concealed Within the hammer handle and which may be extended for use to enable the Workman to space shingles or nails at any desired distance, While the gauge is made of a flexible material Which will not in any way interfere with the use of the hammer so that it may remain extended While the hammer is in use.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying' drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Figure l is a side elevation of a hammer illustrating the use of the gauge and shoiving the gauge partly extended from the hammer handle.

F ig. 2 is a longitudinal sectional view of a portion of the hammer handle showing the gauge partly extended.

F ig. 3 is an end elevation of the hammer handle.

F ig. 4 is a vieiv of the retaining Washer for securing the gauge in place in the hammer handle, a portion thereof being broken away to illustrate the manner of securing the gauge in a given position.

The numeral l indicates the hammer handle which is secured in the usual Way to the driving head 2. The hammer handle is provided with a hole 3 Within which a .flexible rubber rod et is slidable.

The rubber rod is sufliciently stiff to act as a gauge, While at the same time it will bend and in no Way interferes with the use of the hammer because it may be bent from side to side.l

.In order to prevent the gauge from falling out of the opening in the hammer handle it has a Washer 5 pressed thereon which may be set at different lengths from the end of the gauge, or the gauge may be held in dif- Speccation of Letters Patent.

ferent adjustments by means of the spring lock 6. The spring lock is secured at the back of the retaining Washer 7. The retaining Washer is secured in the end of the handle by means of two screws 8 and 9, and 1t has a peripheral notch as indicated at l0 through which the short end ll of the pivot lock 6 projects.

rl'he screws 8 and 9 serve to hold the washer' in place and they cause it to bear upon the lock 6 with sufficient force to enable said lock to hold the gauge rod in any given adjustment. The fixed end of this lock surrounds the screw 9, or it may be secured in any other suitable manner.

This gauge is used iWhere a considerable number of measurements of a fixed definite length are to be repeatedly made in conjunction With the tool to which the gauge is applied, and the gauge is of such a nature as to permit it to be continuously extended Without interfering with the Work of the operator. Vhen used in conjunction with a striking tool, a hole is bored in the handle of the tool and the scale of the gauge is made to read a certain number of inches in conjunction with the length of the tool to which the gauge is applied.. The gauge is pulled out from the tool handle the desired amount and locked in any given position by the spring l1 whereupon the total length of the tool and gauge may be used for repeated measurements Without retracting the gauge each time.

The gauge is also especially useful Where a series of short measurements are to be made, as for example: when a Workmanl is laying' shingles it is desirable to have a convenient method of measuring four inches each time a shingle is to be laid; therefore, the gauge would be extended from the handle of the implement with which it is 'used four inches, and this would provide a shoulder to be placed against the shingle already nailed in place and give the measurement for the next shingle, and Without retracting the gauge the implement can be used for driving the nails in place, the gauge not in any Way interfering with the implement because of its flexibility.

It will also be seen that the gauge may be used in the manner just mentioned or in conjunction With the length of the tool to which it is secured as above mentioned.

What I claim is as follows, but various definite 2 neiges? modifications may be made in the Construethrough which the gauge slides, and a spring tion shown in the drawings and above parcarried by said Washer and adapted to bear ticuiarly described form, within the purupon; the gauge to hold it in any desired l0 View of my invention. adjust-ment.
