Philadel hia and State of Pennsylvania, have invente anew and useful Carpet-Cutter, of which the followin is a specification.

The invention re ates to improvements in car et-cutters.

he object of the present invention is to improve the construction of carpet-cutters an to provide a simple, inexpensive, and eflicient carpet-cutter designed or cutting carpets to fit rejecting portions and recesses of rooms an capable of ready adjustment to cut a carpet at the desired angle.

A'further object of the invention is to provide a carpet-cutter of this character capable of enabling a carpet to be rapidly and accurately cut and adapted to securelv hold a carpet and effectually prevent the same from sli p n durin the cutting operation.

Anot er 0 ject o the invention is to provide a carpet-cutter in whicn the cutting mechanism may be swung upward and sup ported out of t away while placing a width of carpet in position for cutting.

- The invention also has for its object to provide a carpet-cutter which may be readily taken apart should any of the parts become broken and require repair.

With these and other objects in view the invention consists in' the construction and arts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hered, itrbeing understood that varisize, and-- minor details of construction within the scope of the claims may be resorted to without departing from the s hit or sacrificing l ous changes in the form, proportion,

The base is provided with a longitudinal slot 7, forming a knife-guide and receiving metallic strips 8 of brass or other suitable material, which are adapted, to support a knife-9 against lateral movement, and which gnables the same to slide freely along the ase.

The knife 9,which is set at an inclination to enable it to be readily drawn throu h a carpet 10, is mounted in a suitable knhe-holder 11, consisting of a substantially rectangular block provided at opposite sides with grooves 12 and arranged in a lon itudinal opening 13 of a hinged guide 14.
