WILLIAM RUSH, Q1? CANONSBURG, PENNSYLVANIA,

COMBINATION TOOL.

I Application filed December 13, 1922. Serial No. 606,597.

To all whom it may concern:

Be it known that WILLIAM RUSH, a citizen ofthe United States, residing at Canonsburg, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Combination Tools, of which the following is a specification.

My invention relates to combination tools, wherein the same may be used as a socket wrench, valve grinder or drill, the tool being so arranged as to be changed in an easy and expeditious manner from one tool to another.

The primary object of the invention resides in the provision of such a device that is simple of construction, comparatively in expensive of manufacture, and highly use ful for a large number of purposes.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a side elevational view of a device constructed in accordance with the present invention, the same being shown as employed as a socket wrench.

Figure 2 is a vertical sectional view of the tool shown in Figure 1.

Figure 8 is aside elevational and cross sectional view of the tool, the same being shown as adapted for the reception of a bore or drilling tool.

Figure 4 is an elevational cross sectional view of an attachment whereby the tool may be employed as a bolt holder and nut remover. 1

Figure 5 is a longitudinal cross sectional view of a specific form of nut engaging socket employed in connectionwith the present device.

Figurefi is a side elevational view of an attachment for the tool, whereby engine valves may be rotated.

Figure 7 is a fragmentary cross sectional view through the gear casing of the tool.

F igure 8 is an elevational viewof a reamtained within the ends of the'casing by split spring rings 6 received within channels 7 formed in each end of the said casing.

Journaled within suitable openings in the cover plates 4, which openings are slightly off center of the platesare the opposite ends of a rotary shaft 8, one end of which projects outwardly of one of the plates 4 and casing operating handle 9. The shaft 8 has keyed thereto adjacent one ofthe plates 4,

a large worm gear 10, which gear meshes with a pair of spaced worm pinions 11, therebeneath, which are keyed to a pair of shafts 12 transversely within the casing and journaled in suitable openings within the cover plates 4. These shafts 12' also have keyed centrally thereon, other worm pinions 13, intermeshing with a worm gear 14 upon the upper end of a pendent shaft 15. This latter mentioned worm 14c rests upon a collar 16, within the casing 1, which collar is formed around an opening 17 in the bottom wall of the casing. The casing 1 has externally formed thereon a pendent sleeve or collar encircling the opening 17 therein, and reduced and screw threaded at 19 at its lower end. I

The shaft 15 projects outwardly of the pendent collar or sleeve 18, and has keyed thereto a thimble 20, which thimble has an angular opening 21 in its bottom wall, and directly beneath the end of the shaft 15. This angular opening of the thimble receives an upper, angular end of an annular shaft 22, which shaft is maintained within the opening of the thimble by a spring pressed dog 23 carried by the thimble and engaging within a notch at the upper end of the shaft.

Loosely engaging over the shaft 22 is a and threaded at 26 for engaging within' a-n gagement with the threaded, reduced end 17 of the collar 18.v

The lower end of the tube 24 is enlarged internally threaded nipple 27, upon the top side, and at one end ot a right angularly" extending housing 28. This end, of the l'iousing is open-and internally screw threaded for receivinga screw threaded plug-29. The opposite end of-the housing has a smaller-opening '80 therein, for allowing, a shaft 31 to project therethrough, the opposite end of thisshatt being reduced as at 32 for engaging'within-a" central socket of a plug 29. Adjacent the inner face of this plug, the shaft 31 haskeyed thereto a. small bevel gear 33"intermeshing with a similar gear 84; upon the lower end of the before mentioned shaft 22, whereby when this shaft 22 is rotated, asimilar movement will be iinparted'to th'e'shatti31. The projecting endotthe last mentioned slrattihas an angular-socket 85 formedthereon for thereception of an angular shank 36 of a nut recciving socket 37, or asimilar shank 390i a valve-rotating member 39- or still further, the. shank 40' of a milling tool 451. These elements are more clearlyshown in Figures 5; Band 8, and the angular shank of each has a notch 42 therein, tor'engaging a pivoted doge3 upon the socket end 35 of the shaft 31, this socket having an opening-to allow the head of the dog to pass through for this; purpose.

As more clearly shown: in Figure 5, the

shank 36 Oct the'nut receiving socket 37 has,

a' longitudinal bore 44- eX'tending therethrough for receiving :oneend of a plunger (15, the opposite end of which carriesan-angular plate d6 within the-socket 37." The plurlgerddis channeled as at 47 for allow ing the same tocsli'de beneath" a transverse pin 4:8 in the bore of'the socket shank 86. A coiled spring 49 between the plate' iti' and inner wall of "the'socket 37tends to normally project the plate outwardly to a position as shown, by allowing this plate to moveinwardlywh'en a nutis to be received within the-socket 37. It will 'there 'fore be seen that when a nut is received within the socket,- the same may be unscrewed from-its bolt and after being entirely unscrewed therefrom, it wi-l'l'be-projected outwardly otthe socket by the spring pressed plate 46.".

Fr m the above description, it will at once be apparent that I have adapted my tool "to bereadi'ly changed from a socket wrench to a valve'rotating tool, or a milling or cutt'ing tool, merely by positioning a desired one of these tool'firnplements which? are shown in Figures 5; 6 and 8 in the-socket 35 0f the shaft "31.,

In Figure 3, my tool is shown as being adapted for the reception iofboringor drilling implements, and in accommodating this tool tor'such purposes, a thimble 50 is keyed to the projectingendoft-he shaft 15, which thimble is to med with a pendent externally threaded skirt portion 51'. \Vithin this skirt portion 51, are the usual pivotally secured pendent drill engaging arms 52. Positioned at its upper end, over the said thiinble is, what may be:-termed,' a -relatively long sleeve 53; internally threaded adjacent its upper endhs atitt'or engagementwith the threaded skirtportion-51' ofthe thimble 50. The lower endot-th'is sleere' converges inwardly as at 55't'oren-gaging the lowcr endsof-th'e drill" receiving arms 52 n'hen the sleeve is screweddownwardly upon the thimble-50 and for properly retaining the drill between the ends of these arms. A nut' 56 may be provided upon the screw threaded end of the casing collarorsleeve 18, to prevent the marring ot these threads-when the device is used as a drill.

In Figured, I have shown an attachment formy device, wherebythe same may be a boltholding and nut removing tool. This attachment includes the tube 56 internally screw threaded atits upper end tor engaging over the reduced, lower, screw threaded end 19 ot'the pendent casing'or sleeve 18. This tube hasrthe reduced portion 57 for re ceiving'a shaft 58, the :upper squared end 59 of which engages within the angular opening 21 of the thimble 20 shown in Figure 2. The reduced portion 5'. of the tube extends through an opening in an arm 60, which arm hasa right angularly bent pendent por tion 61 tormedthercon. The end ot'this bent or pendent portion of] the arm has an annular flange or head 62 formed thereon, and this head'togethcr with the portion. 61 eXtend-swith'ina tube. or cylinder 63 formed vertically u'poucne end'ot anarm 6 1, which arm extends beneath therlirst mentioned arm and is et similar dimensions therewith.

As is clearly shown in Figure 4, a portion of the' reduced end 57 of the tube 56 extends beneath the: opening in the arm 60 and is screw threaded for receiving thereon a'retainin'g' nut 65, theportion of the end 57"of'the tubeabove the arm 60 having: an annular shoulder 66'for close contact with the upper surface of the said arm 60'. The shaft 58 also extendsbeyond the end of the said tube and has k'eye-d thereto an angular sleeve 66; which sleeve has a spring pressed dog 67 for engaging within the notch 47 in theshank ofthe nut receivingsocket 37"shown"in Figureli. The lower arm 64 has an angular opening" 68 therein for'receivin-gth'e shank 69*of'a bolt head receiving' socket-70'. The shank of this socket is also provided. with a notch} for receiving IOU the head of a spring pressed dog 71 carried by the arm for firmly-retaining the socket therein.

The bolt head and nut receiving sockets are normally maintained in close proximity to each other by a relatively strong coiled spring 72, within the tube or cylinder 63. The lower end of this spring engages upon the head or flange 62 of the pendent portion 61 of the arm 60, the upper end engaging beneath a cap 73 internally screw threaded for engagement with external screw threads on the upper end of the tube or cylinder 63, this cap having a central opening 74: therein for allowing afree sliding movement of the portion 61 of the arm 60.

In view of this latter mentioned construction, it will be readily understood that when the attachment shown in Figure 4, is properly applied to the tool and after the nut engaging socket has been received within the socket of the sleeve 66, the arms 60 and 64.- may be sprung away from each other, whereby the bolt head and nut receiving sockets may engage over the head of a bolt and the nut respectively.

Any turning movement of the tool handle 9 will occasion av rotary movement of the shaft 58 for consequently removing the nut from the bolt, the socket 70 preventing the said bolt from turning. In View of the spring 72 within the tube or cylinder 63, the arms 60 and 64L may be so extended as to adapt the attachment for any length of bolt.

It is to be understood that the milling tool shown in Figure 8 is to be used for milling the surface of an engine block or the like at a point adjacent the bolt and nut connect-ions, it being at the present time,

almost an impossibility to properly use a socket wrench for removing the nuts, due

the close proximity of these nuts to the engine blocks. As shown in Figure 8, the milling end of thistube is hollow and has an external milling surface, whereby the same may be engaged over a nut for properly milling the surface of the engine block adjacent the nut for permitting the employ ment of my socket wrench.

While I have herein shown and described the preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein, without departing from the spirit on the driven. shaft, a housing mounted transversely 011 the lower end of the tube element, a shaft rotatable in said housing and disposed at an angle to the shaft in the tube element, driving connections between the shlaft in the tube element and the shaft in the housing, the shaft in said housing having a socket formed in the end. portion thereof, and a work engaging element having a shank for removable engagement in said socket adapted to project from said housing in line with the shaft in the housing.

In testimony whereof I affix my signature.

WILLIAM RUSH.
