Claims. (01.81-52.35)

This invention relates to combination tools used particularly in repairing motor vehicles such as in service stations, garages, body shops and the like and also for use in wood working shops, mills, factories, and in the home, and in particular a screw driver having a relatively heavy hammer slidably mounted on the shank whereby with the bit of the screw driver in the slot in the head of a screw the handle, which is resiliently mounted on the shank is reciprocated with a hammer action for loosening the screw before turning.

The purpose of this invention is to provide a combination hammer and tool in which the tool is slidably mounted in a handle and in which tools of difierent types may be used in the same handle.

In taking machinery and other devices apart it is often diflicult to remove screws, nuts, bolts, and the like, particularly where such parts are subjected to the elements so that corrosion and rust exists in the threads, or between the parts and in using a conventional screw driver, socket wrench, or the like it is often necessary to use a hammer to jar the parts loose before turning is possible. With this thought in mind this invention contemplates a tool having a relatively heavy handle slidably mounted on a shank thereof wherein the handle is adapted to be reciprocated to provide a hammer for jarring screws, nuts, bolts and the like loose from elements in which they are threaded.

The object of this invention is, therefore, to provide means for forming a hammer in combination with a screw driver whereby the same tool is used for jarring a screw loose and also for removing the screw.

Another object of the invention is to provide a combination tool having a handle with a hammer action therein adapted to be slidably mounted on a shank of a tool and in which tools adapted to be used in combination with the handle are interchangeable.

A further object of the invention is to provide a combination too-l having a hammer action handle in which the tool is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a plurality of tools having extended shanks with flat sides and with spring actuated balls incorporated therein and a handle having an opening in one end for receiving the shank of a tool and having a spring in a bore therein for returning the handle to an outwardly disposed or starting position.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a side elevational view showing the combination tool with part of the handle of the tool broken away showing a longitudinal section therethrough.

Figure 2 is a cross section through the handle taken on line 22 of Fig. 1 showing the spring in the handle.

Figure 3 is a cross section taken on line 3-3 of Fig. 1 showing a spring actuated ball for frictionally retaining a tool in the handle.

Figure 4 is a side elevatonal view showing a shank of a "ice tool and illustrating the use of a socket, for nuts, bolts, and the like on the end of the shank, part of the socket being broken away and the remaining part shown in section.

Figure 5 is an end elevational view of the socket shown on the tool in Fig. 4.

Figure 6 is a side elevational view showing a tool having a pointed end providing a punch and adapted to be used in the handle shown in Fig. 1.

Figure 7 is an end elevational view of the tool or shank shown in Fig. 6.

Figure 8 is a side elevational view of a shank having the webs of a Phillips head screw driver on the extended end and with parts broken away.

Figure 9 is an end elevational view of the shank shown in Fig. 8.

Figure 10 is a side elevational view of a tool having a special tip on one end and also with parts broken away.

Figure 11 is an end elevational view of the tool shown in Fig. 10.

Referring now to the drawing wherein like reference characters denote corresponding parts the combination tool of this invention includes a substantially cylindrical handle 10 having a sleeve 11 extended from a head 12 threaded in the handle with threads 13, a spring 14 in the handle and positioned between the inner surface 15 of the head 12 and a washer 16 retained in the sleeve with a spring locking ring 17 and positioned to engage a shoulder 18 of a shank 19, such as the shank of a screw driver 20 and which is slidably mounted in an opening 21 extended through the end 22 of the handle and retained in position by a ball 23 in a socket 24 in the shank 19 and urged outwardly by a spring 25.

The spring assembly is incorporated in the sleeve 11 extended from the head 12 and positioned in the handle 10 and a cylindrical portion 26 extended from the shoulder 18 at the end of the shank 19 extends through an opening 27 in the washer 16 and into the spring.

With the parts, as illustrated in Fig. 1, a bit 28 of the screw driver may be inserted in a slot of a screw and by reciprocating the handle on the shank 19 the screw is hammered until the screw loosens. With the opening 21 in the end of the handle having flat sides to correspond with the flat sides of the shank 19 the screw driver is adapted to be actuated in the conventional manner for removing screws from material or for inserting screws therein.

In the design illustrated in Figs. 4 and 5 a shank 29, similar to the shank 19 is provided with a section 30 having flat sides that are adapted to be positioned in a socket 31, such as thte socket of a socket wrench, with the section in an opening 32 in one end of the socket and with the opposite end of the socket provided with an opening 33 having flat surfaces 34 which are positioned to receive a square or hexagonally shaped nut, bolt head, or the like. The shank 29 is provided with a spring actuated ball 35 and the opposite end is provided with a cylindrical section 36 that extends from a shoulder 37 similar to parts on the inner end of the shank 19.

In the design illustrated in Figs. 6 and 7 a shank 38 is provided with a punch 39 on the end of a cylindrical section 40 and the opposite end is provided with a cylindrical section 41 that extends from a shoulder 42. The shank 38 is also provided with a spring actuated ball 43 by which the shank of the punch may be retained in the opening 21 in the end 22 of the handle 10, similar to the shank 19 of the screw driver.

In the design illustrated in Figs. 8 and 9 a shank 44, which is provided with a spring actuated ball 45 and a cylindrical section 46 extended from a shoulder 47 is provided with a bit 48 having cross webs 49 to correspond with a Phillips head screw or the like on the extended end;=andin Figs 'and 11 a shank 50 having a spring actuated ball 51 therein .and having .a. cylindrical section 52 extended from a shoulder 53, similar to corresponding parts of the screw driver shank 19 and -theopp"osite end 'of th'e shank 50 is provided' v'lith a cylindrical section 54 havin a special formatio'n S5 with -ridges 56-and 57 on the ed'ges Of a Web'eX'tended therefrom.

I It will be understood-that any 'suitable n-umber of tools may be provided on the ends of shanks, sir'nilarto the -shank l9 and the tools may besubstituted for the screw driver :when use thereof is desired.

By this means a combination tool is provided wherein ":screws, bolts, nuts, and the like may be jarred-loose by hammering with the handle or head 6f the screw driver,

or other to'ol a'nd wherein, afte'r loosening, th'e screws, bblts, 'nuts, or the-like may -be turned and readily removed from parts heldfith'ereby.

The t'ool is als'o particularly ada ted for Working -'out dents in doors of motor vehicles without removing-the inrier panels of the do'ors. 'By 'drillingsmall holes in-the inner panels the b'ittnay' be placed againstthe inner sur- :faeamf the "outer p'anel- -and th'e outer wall of -'thedoor hammered by the weight or handle. After working the de'nt frcim the Wall of the' door the holes in'the-inner panel may be covered with-tapeor' thelike.

J Each fs'mall ho le 'in =the t innerpanel =would 'pertnit the working :of an area of several square inchs of the outer wall.

It'will-be understood that-modifications, within the scope ofthe appended claims,'may-be made in the design and =arra'ng'e'ment of the parts without-departing from the :spirit of I the invention.
