CUTTER ATTACHMENT.

Application filed .Tune 4,

To all whom t 'may concern Be it known that I, JOHAN ENHOLDT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Cutter Attachments, of which the following is a speciication.

rThis invention relates to improvements in cutter attachment particularly adapted, though not necessarily limited in its us with paper hangers cutters.

Heretofore in paper hanging and especially when fabric is placed upon the walls considerable difficulty and inconvenience is experienced in cutting off the overlapping portions of adjacent strips of material so that the adjacent ends will abut and lie smooth and flat upon the wall. At present this is generallyT done by means of a knife and the use of a straight edge along which the knife is drawn, while the fabric rests flat aeainst the wall. This operation is not entirebly satisfactory because in order, to make a clean cut the edge of the knife cuts into the plaster of the wall which dulls the knife. Furthermore, as the fabric has'paste applied to thefback thereof it is more or less n moist and only a very small amount of the fabric can be cut at one time as the edge ofv close proximity with the edge of the cutter so'that the fabric will be readily cut by drawing the cutter therealong, and the surface of the wall will not be injured or marred either by the attachment or the cutting edge of the cutter.

A further object is to provide lan improved attachment of this character embodying a shoe like portion which extends over and co-operates with the cutting edge of the cutter and which attachment is adapted to be turned back or out of the way,pwithout detaching the same from the cutter, so as' to expose the cutting edge of the cutter for' sharpening or other purposes.

A further object is to provide an improved device of this character which will be sirn` 1923. Serial No. 643,215.

ple7 durable, cheap, light andcompaot in n `of thek several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention,l and in which-f Figure 1 is a View in side elevation of a cutter having an attachment constructed in accordance with the principles of this invention applied thereto.

Figure 2 is a detail sectional view taken lon line 2 2, Figure/1.

Figure 3 is a view similar to Figure 2, with parts omitted.

Figure 4 is av vertical sectional view taken on line 74%, Figure 1.

Figure 5 is a detail'perspective view of the attachment detached from the cutter and withv parts broken away.

Throughout the specification and lclaims` the term shoe like member will be applied to one of the parts for describing the same,

but it is to be understood that this term is not to be considered as aterm of limitation v Vber which is suitable for the purpose.

Referring more particularly to the drawing the vnumeral 10 designates a cutter having a handle l1 applied thereto and which, in the present instance, illustrates a cutter or knife which is usually employed by paper hangers and commonly known as apaper hangers knife. It is to be understood, howf ever, that thisattachment maybe applied to any other form of knife. f-

The numeral l2 designates a substantially U shaped member of` any desired size and configuration and constructed of any suitable material butrpreferably of a resilient material such as metal or the like. tion of the member l2 is cut away as at 13 to provide a depending portion let arranged preferably at substantially right 'angles' to the portion 12.

A shoe like member l5 also constructed of any suitable material, but preferably metal, is pivotally connected at one end as at 16.

A porwith the portion 14 so that the member 15 will be adapted for free pivotal movement about the pivot 16 to be moved into and out of position and substantially parallel with the member 12.

The shoe like portion 15 is provided with an opening 17 preferably through the bottom thereof and at a point preferably spaced from the extremity 18. A deflector 19 is arranged adjacent the opening 17 so as to detiect particles of the material being cut by the cutter and also to form a discharge outlet for any paste which may be carried by the material into the shoe like portion or between the shoe like portion and the edge of the cutter 10.

rllhis opening 17 may be of any desired size and the deflector 19 is preferably formed from a portion of the bottom of the member 15 and deflecting the same upwardly and into the shoe like portion 15.

Any suitable means may be provided for yieldingly restraining the member 15 from movement about its pivot 16 with respect to the member 12. To that end a yportion of the member 12 may be cut and shaped to form a pair of co-operating spring like jaws 20' opening downwardly and in a direction towards the member 15. The member 15 is provided with a portion 21 adapted to pass between the spring like jaws 2O to be yieldingly held thereby and thereby hold the member 15 in an operative position.

rlhe jaws 2O and the portion 21 may be r of any desired configuration.

The member 15 is also preferably provided with an upwardly projecting beveled ortion 22 so arranged as to deflect the material which is being cut.

The device thus constructed is adapted to be applied to the cutter 10 by inserting the member 10 between the

members

12 and 15, through the end of the members adjacent the pivot 16, as shown in Figures 1 and 4, so that the member 12 will engage over the top edge of the cutter 10 and the shoe like portion 15 will engage over the cutting edge of the cutter.

The parts may be secured to the cutter in any desired or ksuitable manner but preferably by means of fastening screws or bolts 23 which pass through the walls of the member 12 and over the upper edge of the cutter 10 and are tightened so as to cause the member 12 to grip the upper edge of the cutter 10. The cutting edge of the cutter will then enter the shoe like portion 15` and also between the upstanding portions 21 of the member 15. rlhe cutter blade 10 will also pass between the dependingv jaws 20 of the. member 12 as shown more clearly in Figure 4.

ldith the parts thus arranged the jaws 2() will co-operate with the cutter 10 for holding the shoe like member 15 yieldingly in position, and to that end one of the upstanding portions 21 of the shoe like member 15 will pass between the cutter blade 10 and the adjacent jaw 20. If desired each of the jaws 20 may be provided with an odset portion` or recess 24 adapted to receive a pro.- jection 25 on the respective portions 21.

lVhen the parts are applied to the cutter as shown in the full line position in Figure 1, the extremity 18 of the shoe like member 15 will be directed away from the cutting edge of the cutter 10 and will preferably terminate adjacent the forward edge of the cutter so that in use the shoe like member 15 will be directed under the material to be cut, and this will raise the material as the cutter is advanced to cause the material to slide up the inclined surface of the portion 18 and will direct the material between the shoe like member and the cutting edge of the cutter and press the material against the latter, to be severed. The deflector 19 is so arranged that it will stand in close proximity to the cutting edge so that any paste or foreign matter which is carried by the material into the forward end of the shoe like member 15 will be discharged through the opening 17.

With this improved construction it will be manifest that the material may be cut while the same is applied to the wall with out danger of marring the wall and also withoutdanger of dulling the cutting edge of the cutter by reason of its coming into contact with the wall surface. The shoe like member will elevate the material to be cut and will also hold the cutting edge out of contact with the wall.

When it is desired to gain access to the cutting edge of the cutter for sharpening or for other purposes, the shoe like member 15 may be moved about its pivot 16 into the dotted line position shown in Figure 1, thereby permitting the edge of the cutter to be sharpened without necessitating the removal of the attachment from the cutter.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
