MAGAZINE scRnw DRIVER. ,l

Application led January 20, 1922. Serial No. 530,589.

To all 'whom it may concern." v

Be it known that I, HENRYSIMON, a citizen of the United States, residing at Santa Ana, in the county of Orange and State of California, have invented a new and useful Improvement in Magazine Screw Drivers, of which the following is a specification;V

This invention has referencetomultiple tools, and more particularly to multiple screw drivers, although the invention `nay be applied to certain other types of multiple tools, but for simplicity, the description will be limited to a multiple screw driver, without necessarily being confined thereto.

In accordance with the invention, there is provided a handle of appropriate size, in which there is housed a plurality of screw driver bla-des, preferably of different vsizes or specically different capacities, and so arranged that a chosen one of the blades may be projected from the handle or housing into position for use, to the exclusion of the other blade or blades, and the chosen blade is there clamped or locked against retraction into the housing. The-projected blade may be subsequently retracted and the second blade be similarly projected and clamped, with- ,out either blade interfering with the other blade, or there being any danger of loss of either blade.

Besides the casing vand the blades, the screw driver structure includes a magazine or change-shell, in which the blades may be stored and shifted at will to bring one or the otherjof the blades into the center line of the casing. When the parts are appropriately assembled, and one ofthe blades is projected, the projected blade is clamped in the projected position and the other blade is at the same time housed in the magazine in the retracted position, and cannot then move more than a minimum distance lengthwise of the magazine. Y

The construction of the tool is such that the blades may be shifted laterally, one at a time, solely by gravity, while the blade which is not projected cooperates to guide the blade, which is projected, into operative or working position and back again into the handle of the screw driver. j

The screw driver body or -casing is provided atone end'with a chuck having split jaws and a screw sleeve, through which either one of the screw-driver blades may extend, with .the blade having a butt end too large to pass through the chuck, and the shank of the blade is small enoughin diameter to pass through such jaw. The

.clutch sleevemay be manipulated to clamp the split jaw upon the shank of the blade so tightly as to hold the projected bladeagainst any liability of the clamped blade being lretracted' by any force to which the blade is` s subjected when in use. i i

Thev inventiony will be Vbest understood from a consideration ofthe following detailer description taken in connection with the accompanying drawing forming part of this spe-cication, with the understanding, howeverythat the invention isnot confined 7o i `to any strict conformity with theshowing of the drawing, but may be changed and' modified so long as such changes and modiiications markno material departureffr'om -the salient featureszof the 'invention as ex'- pressed in the appended claims@ j In the drawing Q "Fig l is anelevaticnof-'a screw driver .embodying the invention.

The handle-or casing lv` is designed to house appropriate screw-driverv blades 2,

VIt is necessary/,"however, Ythat its diameter shouldbe greaterfin one' direction 'than the other, and thatits leastl diameter should ber justk sutiieient'to'receive the screw housing l is a change-shell or magazine 7 of y multaneously laterally of the handle byA gravity andprojectable also by gravity one at a time lengthwise ,through the longitudinal center line of the magazine, said handle having at its outer end a clutch provided with a passage on such center line and. operable to clamp the screw-driver blade in the projected position.

5. A magazine screw driver or other like tool, comprising a hollow handle with an elongated flattened elliptical-shaped magazine of a size to contain two blades side by side in contact with each other and leave room for their lateral movement in one direction only, said blades being free to move laterally under the action of gravity, and movable one at a time lengthwise of .the magazine and handle also by gravity, and a clutch and manipulating means therefor at the forward end of the handle provided with a passage on such center line to grip a projected blade whenextended beyond the clutch.

6. A magazine screw driver or other like tool, comprising an elongated hollow handle, with a longitudinally extended magazine therein, said magazine being of elliptical cross section having a width in one direction to accommodate two screw-driver blades in side by side contact, and a width in the other direction which constrains the blades from movement in that direction, and a clutch at the forward end of the handle and having a through passage located in the longitudinal center line thereof, said clutch having a clamping sleeve to compress the clutch onto a projected blade which is passed through the chuck from the inside. l

7. A magazine screw driver or other like tool, comprising a hollow handle with a fixed magazine centralized therein and ilattened into elliptical form to accommodate two blades lengthwise of the handle in side engagement and tol contact sidewise and crosswise of the handle, to locate either blade in the longitudinal center line of the handle,A the forward end of the magazine being open and said opening being on such center line, whereby either blade may be caused to project individually through the front end of the handle and be held in the projected position.

8. A magazine screw driver or other like tool, comprising a hollow handle with an elliptical-shaped magazine located centrally therein, said magazine extending from side to side of the handle and secured to the inner walls of the handle, and the fiat sides of the magazine being spaced from the corresponding sides of the handle, a clutch at the forward end of the handle provided with a. through passage on the longitudinal center line of the handle, said forward end being contracted, and the forward end of the magazine terminating at the contracted portion, and a pair of screw-driver blades normally housed in the magazine, and said blades being located to gravitate in the magazine into side by side relation, with a chosen one of the blades in line with the clutch for projection therethrough by gravity and there held by the clutch against retraction.

In testimony that I claim the foregoing as my own, I have hereto aiiXed my signature.
