COMBINATION Toor. v n' Application filed December 31, 1927. Serial No. 243,819.

This invention relates to tools or instruments of the General type described and claimed in my etters Patent of the United States No. 1,667,462 of April 24th, 1928.

Among the objects of the invention is to enlarge the field of usefulness of this tool Yso as to provide for a more flexible interchange of instrument blades or attachments with respect to a common handle and to facilitate such interchange in an easy practical manner.

More deiinitely stated, the general object and scope of this invention is comprehended in aconstruction involving a handle, a tool or-blade socket in the nature of a hub journaledy permanently in said handle so as to be swung into open or closed positiomand a Series of blades, tools, or other instrument-alities adapted to be inserted selectively and 0 interchangeably into said socket piece or hub.- 1

With the foregoing andother objects'in viewV the invention consists in the arrange- Y 2F ment and combination of parts hereinafter 0 described and claimed, and while the invention vis not restricted to the exactY details of construction-disclosed or suggested herein, still for the purpose ofV illustrating a practical embodimentl thereof reference is had .to `the accompanying dra-wings in which like reference characters designate the same parts inthe several views, and in which-f Figure 1 is a plan view of a blank from which a preferred form of the handle mechanism may be formed from sheet metal. Y

Fig. 12 is a. blank showing one way of forming the holder of Fig. 9. f

Fig. 13 is -a side view of-a different type of; blade. Y

. Fig. 14v is -a still further form of inter'- changeableblade or tool.

Referring now ,more specifically to the" drawings, l show a handle 15 -formed as v shown inV Fig. `1 from a sheetV metal blank having two cheek plates 15a and 15b foldable into parallel planes-,along'a yback or rib 16 and provided Vwit-hregistering holes *17" and 18 at or near its opposite ends', lthe holesV 17 for a hanger or link 19, and the other holes-fora pivot pin`20. These cheek plates are spaced from eachl other as shown in Fig. 8. rlhe pivot-end ofthe handle is formed on arcs of circles at 21approXimately concentric with the pivot holes 18, and the adjacent end of the rib 16 constitutes ashoulder at 22.

'lhe hub or socket member of Figs. 3,4, 5, and 7 is shown as a whole at 23 and comprises two substantially similar cheek 'plates or disks 24 having registering holes 18a and 80 a central connecting web 25 which in the iinished structure, as shown in-Figs. 4 and 7, constitutes a shoulder adapted to abut against the shoulder 22'in the open position of the instrument. lt will be understood thatl the socket member is so formed as to provide an open space or socket .26 bounded on one; sideby the shoulder web 25 and-onthe oppositeside by a closed web 27. Also it will be Y noted that the socket member otherwise is "i approximately circular and with the pivot holes 18a central thereof and adapted to register with the pivot holes 18 of the handle and through all of which holes the ypivot pin 20tpasses fastening'the handle and socket 95 y" member permanentlytogether. The socket lnemberis of relatively thin structure andl operates inthe lspace between the side plates or` cheek pieces 15a and 415b ofthe handle. These two parts may be held from free rela- 10 tive rotation by friction or any other suity able means, as, for instance, the positive lock- The parts are so made that they are retained normally in connection by friction, but they may be separated by drawing the two parts directly away from each other. Fig. 13 shows a different type of blade in the nature of a surgeons lance 32 provided, however, with a similar socket and slot 31 for the Y purposes stated above. The preferred form,

however, of detachableA or interchangeable instrumentality is shown in Fig. 9 .which constitutes a holder 33 of sheet metal formed f from the blank as shown'in Fig. 12 and comprising two side portions 34 and 35, at least one of which is provided with anintegral shank xportion 30a having a slot 31. At the end ofthefholder 33 remote from the shank there is provided a locking pin 36, and while the main portions tof the sides 34 and 35 may be Vapproximately parallelto each other and slightly spaced, they are preferably swaged inward toward each other at their mid portions as shown at 37 for the purpose of grippingtightly upon the sides of a blade 38 adapted for co-operation with such holder.

'Ihel blade 38 has a sharp cutting 'edge 39 and is made preferably of substantially rectangular form but provided at its ends` with a pair of notches 40 and 41, each end design being a duplicate of the other. The blade body is made preferably of uniform thickness and approximating the normal space between the side pieces 34 and 35 of the holder but greater in thickness than the space at the swaged portion 37. With either end of the blade inserted into the holder as shown in dotted lines in Fig. 9, the notch 40 at'such end-will receive the pin as an anchor means or'fulcrum and then the back edge of the blade will be forced directly into the channel of the holder where it will be gripped snugly as shown in Figs. 9 and 11 and where the device may be used as a sharp cutting knife or scraper when the holder shank 40a is inserted into the socket piece 23. Theholder; and blade therein maybe swung around into'- the handle in a mannersimilar to the action of a knife blade in an ordinary knife handle for carrying purposes and swung outward into open position for cutting purposes. The hole or, notch 40 at the opposite end of 'the'blade from theone already described is normally idle but the notch 41 adjacent thereto is employed vfor the application of a pry tool or instrument such as a small coin indicated at C in Fig. 9 which may be inserted between the end of the blade and the adjacent end of the handle for the purpose of starting the blade outwardfrom the holder' for the purpose of turningthe blade end to end or` for the interchange of one blade for another. Obviously when one end or point of the blade 38 becomes dulled the other end may be turned for use by removing the blade as just described and lturning it end to end and inserting it as before described. Fig. v1li gives a suggestion of a still further modificationfof instrumentalities, the same comprising a holder 33a in the nature of asafety razor guard and adapted to receive and hold. -any suitable bladefor shaving or other pur-- poses,-but providedwith a shank 30?) having .a notch orslot 31 made Ato conformV to the socket 26 in the socket piece in'whichit'is adapted to be used interchangeably the same as all the otherA devices set forth herein. It will be understood that many other forms of blades or tools may be used in this manner provided they are provided with shanks adapted ,to fitiinto the socket piece inter changeably. I As la commercial propositiom.

these handles, socket pieces, and blade instrumentalities are made in sets so that a single handleA and socketpiece may be used for any desired number of blades interchangeably..

I claim: v 1. Ina combination tool, a handle, ahub 4 loof in the handle for engaging a tool means, said hub c onsistingof a single sheet of `material comprising a plurality of che'ekplates inter-v connected by arweb, another oppositely positioned split web, and pivot means passing' through the cheek plates and mounting the hub on the handle, one of said webs coacting with the handle as a stop.

V2,. In a combination tool,a handle having a circular end, pivot means-thereon at said end, a hub on the pivot means, said hub consisting of a single piece of sheet material comprising a plurality of cheek plates interconnected by a web, and means including a tool holder having'a slotted end received in the hub, and with the slot receiving the pivot means, said tool holder having pin means at the free end thereof, and a blade positioned in the said holder, said blade Vhaving a recess at one endto engage the'pin' means, and

a recess at its oppositeend adjacent to the center line of the handle through the center ofsaid circular end, thelast mentioned recess being outside of the tool holder whereby the blade may be pried out thereof with the circular end of the handle acting as a pivot.

3. Ina combinationtool, a handle, pivot f means thereon, a hub on the pivotmeans, said hub comprising arplurah'ty of cheek plates, interconnected by a web, and'means including a tool holder having a slotted end received in the hub, and With the slot receiving the pivot means, said tool holder having pin means at the free end thereof, and a blade positioned in the said holder, said blade having a recess at one end to engage the pin means, and a recess at its opposite end normally exposed from the holder to permit of engagement of the blade for removal thereof, the body of the holder being to one side of the axis of the handle,the end of the blade adjacent to the handle being spaced therefrom d for easy access of the exposed recess and to permit the application of a pry thereto with the adjacent end of the handle acting as a pivot.

In testimony whereof I aiix my signature.

GEORGE A. LOGAN.
