Fig. 4 is an inverted plan view of 8.

Fig. 5 is a fragmentary sectional view of the tool showing the bracket in position and arrying a compass.

Fig. 6 is a plan View of a stamp.

Like reference characters denote corresponding parts throughout the several views.

Draftsi'nen making shop drawings, workof various kinds have occasion to repeatedly draw circles, T-unions, elbows-etc, in tne course of a complete drawing and much time is lost bydrawing the same thing over and over. To speed up this n g may be made in stock stamps which are interchangeably fitted in the end of the tool and then instantly applied to the drawing. At the same time the tool is provided with a compass-carrying attachment or bracket which permits instant use of either the tool as a stamp or center finner or marker, or of the compass. p

The tool comprises tubal; r body portion 1 threaded interiorly at both of its open ends, one end receiving a threaded cap orplug 2 and the other a stainp il threaded as shown, the stamp being perforatedv centrally and forming a closure for the body. The outer face of the stamp 8 carries the impression of a circle, elbow or like figure which may be readily impressed upon the work in a manner to be hereinafter set forth,

The body 1 is formed with a contracted portion 4 provided with diametrically'opposed

longitudinal slots

'lhe spring 18 will yieldingly'thrust the pointed end of the pin 9 beyond the adjacent end of the body 1 and in this position the pin may be used as a marker. When a slight blow by hand is administered to the stamp. A colnear its'lower and collar 12is loose cap 2,however, the spring 13 will be 'con- I tracted, the pin retracted and the stamp caused to register its impression upon the work. I

A bracket comprising ashort bar 14 and a long bar 15 connected by legs 16 isprovided,

said bars being formed with diametrically opposed perforations 17 and the bar-15 formed with a terminal notch 18, said bracket being adapted for disposal in the slotte'dport-ion 5 of the body 1 the bracket perforations 17-receiving the pin 9"whereby said bracket is retained in position.

One leg 190i a compass is fitted to the notched end of the bar 16 and secured in p0- ition by thethumb screw 20,- the other leg 21 being then ad usted and used to mark centers, measured distancesor spaces etc. Dista nces from the pointed end 10 of the pin 9v to the marking end of the leg 21 can be read-' ily marked off, the compass being manipulated by the bracket and tool body grasped by hand.

What is claimed is I 1. In a markingand stamping tool, a tubular body having a contracted portion, a

2. In a marking and stamping tool, a tubular body, a sta n 'o in one end of said body, a

pin extending longitudinally of said body and stamp, a collar fast upon said pin, a

. collar loose upon said pin, the movement of said loose collar in one direction being limited by the said body, anda spring encircling said pin and connecting said collars.

3. In a Inarking-andstamping tool, a. tubular slotted'body portion, a pin extending through said body portion, and a bracket arranged in the-slotted portion of said body and perforated to receive saidipim said bracket being notched to receive one leg of a compass.

1 In a marking and stampin gtooL' a onepiece tubular body having a contracted porcollar for yieldingly thrusting said pin out- Wardly with respect to said body and stamp.
