Specification of Letters Patent.
Patented Feb. 20, 1906.
Application filed July 29, 1905- Serial No. 271,723-
To all whom it may concern.-
Be it known that I, RICHARD KNY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New 5 York, have invented certain new and useful Improvements in Knives," of which the following is a specification.
This invention relates to knives, but more especially to what are known as surgeons knives.
Knives of this class must be made of the very best material ca able of being given the big est polish and 0 such form as to admit of being readily cleansed and sterilized, as well as capable of bein given the very finest edge by sharpening and of retainin this edge for the longest ossible time. c must also be of such orm as to permit 0 a firm hold by the hand of the operator, so as to prevent possible slipping, and while they should be made as light as possible they'should be rigid and stiff. Heretofore in order to provide such knives ossessing all of these qualifications the medhods of, manufacture have been difiicult and expensive, and as a consequence of such high original cost such knives have necessarily sold at a comparatively high price, and inasmuch as every complete surgeons equi ment should contain a number of knives t e cost of equipment has been very materially increased thereby.
. It is the object of this invention to provide a knife of this general class which shall ossess all of the before-mentioned qualifications, but which may be manufactured at a very low cost, and with this object in view the invention consists in the im roved construction of knife {hereinafter fully described and afterward specifically claimed.
which this invention most nearly appertains may be enabled to make and use the same, I shall now proceed to describe its construction and operation in connection with the accompanying drawings, inwhich Figure 1 is a perspective view of a knife embodying my improvements; Fig. 2, a view thereof in side e evation; Fig. 3, a view thereof in edge elevation; Fig. 4, a sectional view on the broken line 4 4 of Fig. 2, and Fig. i a sectional view on the broken line 5 5 of Referring specifically to the drawings, the knife comprises three ortions a, b, and c,- a
the blade and I? and 0 combined the ban lo, the portion b serving as the grip or In order that others skilled in the art to I handhold and the portion 0 being on the opposite endfrom the blade at an serving to rest against the hand of the operator to steady his hold upon the knife during an operation as well as to balance the instrument.
It will be observed that the whole instrument is in one piece, preferabl of flat steel, stamped from a sheet or forge .into form for a blank of which to form the knife. This blank is pressed, rolled, stamped, or dropforged by a sin 1e operation into the finished form shown, a ter which it has only to be ground and polished to finish it ready for use.
t nay be nickeled or otherwise plated, if desire The blade a at its back at is substantially of thethickness of the blank and is ground or otherwise brought to a keen edge, as at e, the edge being straight or curved, as may be desire r The part b is longitudinally corrugated, any suitable numberof corrugations bein permissible, three being here shown, as at g, and h, the middle corrugation 9 being rojected toward the side of the handle w 'ch might be called the front, (when the knife is gras ed in the right hand of the operator,) while t e outer corrugations f and h are rojectedfrom the oppositeside or the bac of the knife. When thus grasped in the right hand, the thumb of the operator will rest on the rib of corrugation g and the side of the middle finger in the oove of that corrugation onthe back of t e handle between the ribs of the corrugations f and h, while the part 0 will be pressed against the knuckle of the first finger, thus ving the operator a firm grip upon the kni e and effectually preventing it from slipping in his hand. At the same time the corrugations f, g, and h will stiffen the Whole structure, thus enabling it to be made out of a very much lighter and thinner blank than would otherwise bepossible, whereby the first cost of material is lessened and the manufacture by rolling, stamping, &c., greatly facilitated.
While I have described the formation of a blank from which the knife is afterward shaped, it will be clearly obvious to persons skil ed in the art that the shaped knife (including the two parts of the handle) may be stamped up or pressed out of a sheet of metal at a single 0 eration without first forming a blank and a terward shaping the blank.
Slight changes may be made in the form of the various parts which may suggest themselves to the manufacturer without departing from the spirit and scope of the invention.
What I claim as new isf 1. A knife comprising a blade and handle formed of a single piece of metal, the handle having a central longitudinal rib projected out of 'the general plane of the metal on one side, and two outer longitudinal ribs on the opposite side.
2. A knife comprising a blade and handle formed of a single piece of metal of substantially regular thickness, the blade at the back being substantially of the thickness of the original metal, and the handle joining the In testimony whereof affix my signature in presence of two witnesses.
