1 Beitknown that 1,: ARTHUR' E. SCHUT- FENHAUER, a citizen ofthe United States, and a resident of the cityof South Chicago, county of Cook, and VState of Illinois, have invented certain newA and useful Improvements in Jointers, of which the following is a specification. Y

My invention relates to jointers, thatjis to tools employed b-y bricklayers forremoving the surplus mortar between vadj acent bricks, smoothing the surface of the mortar, and giving the same a particular shape in order to form a neat and finished joint. 'v 'f l' The obj ect of my invention is the produc'- tion of a tool of the character mentioned l which will be of simple construction and efficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter ,described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a partk of this specification, and in which,

Figure embodying the invention. Y

Fig. 2 is a top plan view thereof.

Figs. 3 and 4 are slightly enlarged sections taken on lines m-zv and y-y respectively of Fig. 1, and

Fig. 5 is a view similar to Fig. 3 showing a slightly modified form of construction.

The preferred form of construction, as illustrated in the drawing comprises an elongated metallic body 1 angular in cross section, the outer surfaces thereof being smooth for engagement with the mortar in the operation of the tool. The body 1 is provided with a handle' 2 of substantially inverted U-shape, the ends of said handle being shaped to fit in the groove of 1 and being reduced to engage with openings 3 formed in said bodyat the bottom of said groove, as clearly shown in Figs. 1 and 3. In order to lock said ends of the handle 1 to the body of the tool, said ends are up- Y set, the same being made flush with the engaging outer. surfaces of the body so as to afford no obstruction in the use of the tool. The upper horizontal portion of the handle 2 is provided at its under side with a member 4 of wood to increase the width of this portion and constitute a betterrgrip, 'as' will be readily understood.'V The member 4: 1s se- 1 is a side elevation of a jointer.

the body` cureditothe handle 2 by screws 5 and the I under side of said member i is rounded, as shown in Fig. 3. a

The ends 6 of the body l are inclined inwardly or toward the :handle and the end surfaces 7 are beveled orV inclined toward the l engaging surfaces of the body l, as clearly shown in Figs. l, 2 and 4f.

."In using the tool, the same is pressed into engagement with the mortar between the bricks where the joint is to be formed so that the meeting edge, of theopposite engaging surfaces of the body 1 of the tool enters between the adjacent edges of the bricks. vThe tool is then moved longitudinally, as

will be readily understood. When Vthis is done, the surplus or protruding mortar will be removed and a smooth neat joint formed which will be V-shaped in cross section or of a form correspondingwith that of the body of the tool. 'Through the inward inclination of the ends of the tool a sort of shearing action results or in other words the pressure of the tool upon the protruding mortar is distributed along the inclined ends of the tool which prevents 'tearing or rupturing of the surface of the mortar as might otherwise result were the ends lof the tool cut olf at right angles. Also, through the beveling or inclination of the end surfaces 7 the severing of the surplus mortar will occur at the forward edges of the surfaces 7 leaving a thickness of material corresponding with that of fthe sides of the body of the tool which, as the tool advances, will be wiped over the surface of the joint and thus insure the formation of a joint which is perfectly smooth and even.

Also, by reason of the inward inclination of the ends 6 of the tool, points are formed at the ends of the latter which are of utility in the removal of stones or other foreign matter from the mortar, said ends aording an excellent means for gouging out the objectionable foreign matter. Y

The form shown in Fig. 5 is substantially the same as that described except that in this form the body 1 of the tool is of semi-circular formation whereby, in using the same,y

a groove or joint of semi-circular formation Y same manner as the ends of body l1 and will be inclinedV in precisely the iio open side of the body of the tool and will be shaped to conform therewith.

'Wfhle I lhave illustrated and ydescribed the preferred forms of construction for carrying my invention into effect, these are Capablefof variationv and modification Without departing from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construction set4 forth; but desire to avail Vmyself of such variations'and modifications as vcome Within the fscope of the'appende'd claims.

Having described Vmy invention #what vI Y claimas new and desire to secure by Letters Patent is:

l. Atool of the classndescribed, comprising an elongated bodyfof shell like form the outer face thereof constituting a smooth enga ing surface, the ends of said body being fde' ed" 7by upwardly and 'inwardly inclined .faces intercepting said engaging surface at an obtuse angle, substantially as described.

2. A,jointer of the class described corn- 'prising an elongated sheet metal -body -formedrof:a,;pair ofintegral angularly disposed sides, the ends of said sides being up- Wardly and inWa-rdlyrincleined, theJ-faoes of saidrends intercepting'the outer lfaces of said sides-f at i, an :obtuse r angle, substantially as yidescribed. f

`:1in testimony --Wher'eof .f I, have lsigned -Iny name to this-speciiication 5.in the 'presence :of twoy subscribing Witnesses.
