Be it-known that .I. Wanna: JonN Krumm, a subject of the "King of'Great Britain,

and resident of the city of Ottawa, in the.

Province of Ontario and Dominion ofCanads, have inventedfcertainnew and useful Improvements in Bricklayers Combined Hammers and Scutches, of which the following is a specification. i

, ThlS mvention relates to improvements in and the objects of the invention areto provide a tool of this character consisting of a hammer and scutch combined with interchangeable" blades, whereby the hammer can be used independently of the blades, and whereby the blades can be quickly and etliciently interchanged;

Further objectsfarethe provision of a tool of this kind with a detachable blade member formed with cutting edges at each end whereby the blade is interchangeable by having one end substituted for'the other and invisible by being turned over,

Still'further objects are the provision of a toolof this+deseriptionin whichasharp blade will always bemaintained in thehead, and with which it will be possible to have a plurality of blades,th us enabling those not in actual use with the hammer to be sharpened apart from the hammer.

' It is well known that under existing cir-' cumstances a bricklayer or a workman is compelled to carry two of the ordinary difliculty is overcome.

bricklayers hammers if he wishes to have a sharp tool for use at all times. With applicants interchangeable blade however, this Moreover in addi tion, applicants blade has manyother advantages, in that by simply turning over the blade a.good sharp cutting edge is brought into action, much oftener than is permissible with the ordinary single type of blade now in use. Moreover, the position of the blade at present on the ordinary type of bricklayers hammer only permits wearing...of one side of the cutting edge, the top' side being worn in the process of hacking or cutting, while the underside remains sharp, but is otherwise of no advantage, whereas with aplicants blade when the top side becomes lunt, the blade can be turned over and the bottom side used.

In applicants device, the changeable blade is so constructed as to be readily separated from the hammer part of the tool for sharpscribed, it will be noted ening purposes, and this allows the blade to be drawn and tempered without danger of taking the temper out of the hammer, as is the case with ordinary bricklayers hammers at resent.

I s will be hereinafter more fully .dethat applicants improved combined hammer, and scutch has practically four cutting edges against the one cutting edge at present in use. v

Still further and final objects are the provision of a tool of this character that can be put on the market at a very reas'onable price.

With the foregoing and other objects in view, the invention consists essentially in the novel arrangement and combination of parts described in the accompanying specification and illustrated by the accompanying drawings forming part of the same.

' Referring now to the drawings, in which like characters of reference indicate corresponding parts in each figure Figure 1 is a perspective view of my combined tool complete.

Figure 2 is a side elevation partly in section showing the connection between the adze eye and the handle.

Figure 3 is a detail of the adze head in perspective.

Figure 4 is a perspective detail of the. cutting member.

Figure 5 is a detail of the slip cap for holding the cutting blade more securely in position.

In the drawings, A- designates an embodiment of my improved tool as a whole which may be constructed of any suitable material and comprises a handle 10 formed with a central opening therethrough 11, the lower The top of the adze head is channelled at 19 to receive therein the cutting member 20 terminating at each end in the cutting blades openings 22 20. and 21 and provided with and 23 adapted to register in turn with the central ;"opening 11 1 i gether.

be here noted that the square It should shoulder end formation" of the bolt 16 enables the cuttin member and the head to be tightened on' t e handle without turning the bolt.

Referring more particularly to the cutting member 20, this is formed of a certain depth in the centre and ta ered outwardly therefrom to form at eac end'the cutting ed es 20 and 21, while at the centre it is provi ed on each side with In '24 and designated to engage with the s oulders of the hammer member in operation thereby acting asfectly into the top of the a shock absorber totake the concussion caused by the hammering from the bolt16 thus preventing stripping the thread.

It should further be noted that in order for the cutting member to fit more peradze eye, the top surface of the latter is sloed to conform to the tapered formation of tie former.

From the foregoing the operation of my device will be easil understood.

The tool as comp eted, is shown in Figure 1. The several parts consisting of the adze eye with hammer ortion forming one part having been fitted the handle can be used if necessary in this state b simply tightening the bolts on the central y extending square 'shoulder bolt member 16. However this is only under exceptional conditions. For ordinary every day work, the tool is assembled by also including the cutting member 20, s ipping it into the channel 1n the head of the adze then fitting on the slip over plateand finally tightenin the nut 17.

hen it is desired to change the cutting member so as to provide a new cutting edge, the nut17 is unscrewed, the slip-on blade taken off and the member 20 taken out of the channel 19 and replaced with the ends reversed, and then screwed up. When again one side of the cutting edge has become worn, it is only necessary to again take out the member 20 and turn it upside down,v then tighten it in and a gractically new cuttin edge is provided an so on.

While one cutting member 20 as here shown and illustrated supplies four cutting edges, any number of these members can be kept in stock, and sharpened so that the ininto engagement with dividual using the tool is never delayed orshort of the means of finishingand doing eflicient work. v c

As many changes could be made in the above construction, andmany apparently widely different embodimentsof my invent1on,"within the scope of the claims, constructed withoutdeparting iromthe spirit or scope thereof, it is intended that all matter containedqin the accompanying specification and drawings shall be interpreted as illustrative and notin a limiting sense. What I claim as my invention is:

changeable cutter, a handle having a central bore therein and means formed in the adze head adapted to detachably engage with the handle and the cutter respectively, a cap for the adze head and cutter member and securmg means extending through the ca the cutter member, the adze head an the handle. w?

2. The combination tool as described in claim 1, in which the adze head is formed at the bottom with a recess to receive the handle and channeled on the top to engage with the cutter member. 3. The device as claimed in claim 1, in

which the cap is formed with an opening therein registering with the openin in the through, said ca being formed with overlapping sides a apted to embrace the cutting member and the adze head.

, 4. The device as claimed in claim 1, in which means are providedin the-form of a nut to securely hold the securing means in the form of a'bar or pin extending through the adze head, the cutting member thereon and a handle therein.

5. The device as claimed in claim 1, in which the cutting or scutch member is formed with cutting edges at each end and intermediately with shock absorbing lugs adapted to enga e with the adze hea 6. In a tool 0% the character described, a reversible cutting" member or scutch formed with cutting edges at each end and being of greater depth in the centre than at, each end and sloped .from the centre towards each end and having intermediate of the ends and the centre orifices adapted to re ister-in tu with the orifices in the adze ead to rec 've the securing means therethrough.

In witness whereof I have hereunto set my hand.
