To all whom it may concern:

Be it known that We, ALBERT P. HAUSER, and O'r'ro J. States, residing of Cuyahoga vented certain new and useful vImprovements in Blade-Handling Tools, of which the following is a specification. This invention relates to improvements in blade holding tools, the present embodiment designed and adapted for use in holding and using safety razor'blades of-varying forms and types. The present tool is of particular utility in the hands of sign painters in removing the painted matter of at Cleveland, in the county and the like. ---The primary object -of the invention is to provide a generally improved blade holding tool of the class or type indicated which will be exceedingly simple in construction, cheap: of manufacture, and efiicient in use.

A. further and very important object is the provision of a blade holding tool wherein the blade being used may not only be held in secured position for use but may be readily removed when desired or for the reversal or removal of the particular blade being used.

A still further and important object is the provision of a tool having blade receiving and holdin jaws adapted to be opened and closed in ti g the jaws in one of the embodiments of the invention being adapted to be operated through the movements of the handle loop members by the hand while resting on the latter.

There are other features of the invention residing in elemental combinations and particular construction of parts, all as will hereinafter more fully appear.

With the above mentioned and other ends in View, the invention consists 1n the novel constructlon, arrangement and combination of parts, hereinafter described, illustrated in some of its embodiments in the'accompanying drawings and particularly pointed outinthe appended claims.

Referring to the drawings, forming a part of this specification, Figure 1 is a perspective view of a blade holding tool, constructed in accordance with this invention, in its operative or blade holding position, and equipped with a safety razor blade of .the ordinary Gillette type.

HAUSER, citizens of the Unitedand State of Ohio, have inletters or signs e operation of inserting or Fig. 2, a side elevation, partly in longitudinal section, the base or abutting portion of the jaws bein transformed into a fulcrum and the jaws% held in aniopen position by the inward pres: sure or movement of the spring handle loop members toward each other for releasing a blade or for-holding the, jaws to receive a new blade.

Fig. 3, a side elevation of a modified form in which, as distinguished from Figs. 1 and 2, the jaws are held in a closed position by a holding and adjusting element and the spring loop members tend to openthe jaws.

Fig. 4, a pers ective view 'of a safety razor blade of the ar reinforced or Gem type.

Fig. 5, a top plan view of a blade of the Durham-Duplex type.

Fig. 6, a plan View lette type.

Similarnumerals of reference designate like parts throughout all the figures of the drawings.

-The improved blade holding tool preferably com rises a handle portion and a blade holding sad, the latter preferably corresponding approximately in widthto the len h of the particular blade to be received I an held.

The improved holder is referably made up of a single lengthof s set metal bent midway of its ends forming a handle loo made up of spaced loop members 1, terminatmg in 1*. The jaws terminate at their outer or free ends in parallel extending lip members 1", adapted to engage the intermediate portion of an ordinary safety razor blade.

. As a means of holding and supporting the blade being held between the aws 1 and particularly as a means of preventing relative longitudinal movement or dis laceinent of the blade between the'jaws an holding the outer or relatively fixed distance in front of the lip -members l the jaws are provided at their inner base portions with a blade edge receiving and supporting portion consisting, in the present instance, ing abutments 1. In the present instance, the blade edge supporting abutments 1 are in the specific form of struckout tongues and since the base portions of the jaws extend parallel or in posite jaw is provided with correspondingly? located recesses 01' openings 1*, to recery'e eing moved into and 60 bf a blade of the Gilblade receiving and holding jaws operative ed e of the blade in a '10) of blade edge supportabutting relation the opclamp the blade therebetween.

,man close the jaws and hold thelatter in T1 the position shown in Fig. 1 of the drawings and-with suflicient tensidn to properly "In.the form shown in Fig. 3 the spring loop members are normally in an expanded 101 separated position and are drawn to their position and held in such position close 7 means of an' adjusting and connecting element, said element, in the present instance, 1 comprising a connecting bo t 2, threaded at one end and extending throu h a suitable opening in the base portion 0 the opposite jaw and provided with a knurled thumb nut 2, for drawing or adjusting the jaws or for releasing the latter as desired. As a means of adapting the jaws to receive and hold safety razor blades of varying forms or types, and particularly as a means of receiving and holding a single edge blade 3, having a blade edge bar 3, as

indicated 'in Fig. 4 of the drawings, the

jaws 1 are provided with transversely extending spaced oflset portions 1, said oflset portions, in the present instance, being in the specific form of transverse recesses 01' channel portions conforming on their inner sides tothe generalform o r contour of the blade bar 3' when the blade 3 is inserted with the edge of the latter extending in front of the aws. v

40 As a 'means of opening or causing the jaws 1 to be moved apart to receive or discharge a blade, the jaws are extended rearwardly in parallel relation to provide a base or heel portion 1 at the terminating portion at of the inwardly closed spring loop members naeaeee so that as the latter are moved toward each other by the pressure of the hand of the operator while resting on said handle loop members, the base or heel portion 1 will be transformed into a fulcrum to open the jaws, as shown most clearly in Fig. 2 of the drawm s. In Figs. 1 and 6 of the drawings Having thus described some of the em-' bodiments of this invention, without having attempted to. set forth all the form in which it may be made, or all-the modes of its use, what we claim and desire to secure .by Letters Patent i's,'

1. In a blade holding tool, a one-piece holder comprising outwardly curved and spaced spring loop members terminating at their. ends in parallel extending jaws extending laterally approximately the length of the razor blade to be held, one of said jaws being provided with struck-out tongues forming blade edge supporting ab'utments and the other being provided with recesses to receive said struck-out tongues.

2. In a bladeholding tool, a holder comprising outwardly curved and spaced spring loop members terminating in parallel extending jaws extending laterally approximately the length of the razor blade to be held, one of said jaws being provided in its base portion with struck-out tongues forming blade edge supporting abutments and the other being provided with openings receiving said struck-out tongues when said jaws are closed, said jaws being also provided on their inner sides with transverse channel portions to reoeive a razor blade edge bar.

In testimony whereof we have aifixed our signatures.

ALBERT P. HAUSER. OTTO 'J. HAUSER.
