Be it known that we, ALFRED GRIMONT and HERBERT G. Karr, both citizens of the United States, residing in Venice and Los Angeles, respectively, county' of Los Angeles, State of California, have l)ointly 1n` vented new and useful Improvements in Tools, of which the following is a speciiica-l 'In mechanisms of various kinds there are frequently screws and nuts in recesses and inconvenient places. lVhen there 1s only a screw, or only a nut, ordinary tools, such as wrenches and Screwdrivers, can be used to effect the necessary adjustments or operations. However when there is both a screw and anut, forinstance, when a set-screw or adjusting screw is set by a lock nut, ordi- 4nary tools arel not effective and it is frequently necessary to remove or detach parts of the machine or device 1n order to propnamely, the Ford automobile. This horn has a diaphragm adapted to be operated by an electro-magnet and a screw is carried in the diaphragm and has a plate on itslend to cooperate with the electro-magnet. vThe 'screw is adjustable in the diaphragm to reg'- ulate Athe gap between the electro-magnet and the plate'and vis adapted to be setby a lock-nut. The screw and lock-nut are at the inner or small end part of the horn but cannot be operat'ed from the mouth of the horn by ordinary tools.

An object of this invention is to provide a tool for simultaneously opera-ting a nut and screw, that is, to move the nut and screw at the same time, to move the screw relative to the nut, or to move the nut relative to the screw. The tool can be shaped or proportioned to operate in recesses and inconvenient places where it would be impossible to operate an ordinary wrench and screwdriver. lVith the tool of the present invention the screw and lock-nut "of the horn hereinabove mentioned can be easily and accurately adjusted and set from the'mouth of the horn and without removing'or detaching any part or parts ofthe horn, as is necessary when ordinary tools are used.

l iis we have stated, thehorn above referred to is one instance where a nut and screw are arranged in an inconvenient place. It is to4 be understood that the tool provided by this invention is not in any way limited4 or re= stricted to use in connectionwith ahorn, or like device, of the particular character herein set forth, but that it may be used in connection with machines and devices for any,v uses or purposes.y Thehorn provided on a Ford automobile is a typical and well-known instance where a screwjand nut are provided in an ordinary inaccessible'place. Throughout this specification we refer tothehorn provided on a Ford automobilemerely as a typical instance where the tool may be used and to facilitate a clear understanding of the invention.

A particular feature ofthe invention is 1 the extreme simplicity and cheapness vof con-fE `80 Vvides a tool whichis simple, effective, and inexpensive, and which is extremely handy Y struction of the device. The invention proand convenient for use.

The various obj ects and features 'of the invention will be best and more fully under- Nr" oFFlcr..

throughout which reference is had to companying drawings, in which.- i

view similar to a portion of Fig, t showing the tool in position to operate only the locknut; and Fig. 6 is a view similar to Fig. 5 showingthe toolin position to operate only the screw.

Throughout the drawings numeral 1,0 des- 7 ignates an electric horn of the type provided on the Ford automobile. The horn comprises, generally, a diaphragm 11, an electromagnet 12 for operating the diaphragm 11, a casing 13 for the electro-magnet 12 and rear side of the diaphragm 11, a casing 1-'1 for the front side of the diaphragm 11, and a tapered or flaring horn 15 extending from the central portion of the casing 1lin the manner clearly illustrated in the drawings. A boss 16 is secured to the center of the diaphragm 11 and a screw 17 is screw-threaded inthe boss 16, extending through the boss and diaphragm and carrying a plate 18 at the inner side of the diaphragm 11 opposite the electro-magnet 12. The end of the screw 17 at the'outside of the diaphragm 11 is slotted to receive a screwdriver in order that it may be adjusted to vary the position of the plate 16 relative to the electro-magnet 12. A lock-nut 2O is carried on the outer end portion of the screw 17 to set or lock the screw in its adjusted position. rhe horn is adapted to be operated by alternatingcurrent generated by the power plant of the machine and the screw 17 is adapted to be adjusted and set in position where the plats 18 is the proper distance from the electromagnet 12 to give the desired tone or noise. The horn is adapted to operate with alternating currents of the frequency generated by the power plant of a Ford automobile and will not satisfactorily operate with ordinary alternating current such as is used for heating, lighting and commercial purposes. For this reason the screw 17, and therefore the plate 18, must be adjusted when the horn is in place on the machine', or it must be adjusted and then placed on the machine for trial. In ordinary practise the horn is removed from thev machine, is clamped in a vise, and is coQnected with a Ford generator. The adjusting is then done with ordinary tools through the horn. When adjusted the horn is replaced inthe machine. This method is costly and not altogether satisfactory. Very often when a horn is adjusted to be operated by one generator itwill not be properly operated by another generator'.

The tool provided by the present invention comprises, generally, a frame 25, a wrench 26, and a screw-driver 27. The wrench 26 is carried at one end of the frame 25, while the screwdriver 27 is carried in the frame 25 to be concentric with the wrench v26.- As far as the present invention is cononto its end. lil/'ith this construction it is obvious how the frame may be made of any desired length and how it can be easily and inexpensively replaced if broken or damaged.

ln accordance with the preferred form of the invention, the outer part- 811 of the cap 31 is round, as shown in Fig. 3, and the wrench 26 is arranged concentrically on the cap 31. ln the form of the invention shown in the drawings the wrench 26 is a socket wrench and is formed integrally with the cap 31. `When this construction is employed it is preferred that the tool be provided with a plurality of caps 31, formed with wrenches of different sizes and shapes. This allows the tool to be used in connection with nuts of Various sizes and shapes. 1t will bc readily understood, of course, how the cap 31 can be very easily and quickly removed and replaced due to its being screw-threaded on the end of the body 30.

The screwdriver 27 may be of simple construction, for instance, it may comprise a straight shank 40, the inner end of which is carried in a bore 41 formed concentricallyv in the cap 31 and opening into'the socket 26, and the outer end of which is carried in a bore 12 formed concentrically in the cap 32 and a boss 413 formed on the c-ap 32. The flat screw-engaging part 15 is formed on the extreme inner end of the shank 10 within the wrench 26, while a handle 17 is formed at the eXtreme outer end of the shank 4() outside of the cap 32. The screw-engaging part 45 may be shaped in proportion to properly cooperate with the slot in the outer end of the screw 17, while the handle 27 may be of any desired shape, being preferably shaped so that it can be easily and conveniently gripped by the operator of the tool. A pin 50 may be carried in the shank 40 within the body 30 to engage the cap 32 and limit the outward movement of lthe screwdriver in the manner clearly shown in F 2. rIhe inward movement of the screwdriver will be limited by the handle 17 engaging the cap 32. The pin 50 is preferablyI detachable froml the shank 4.-() so that the screwdriver can be removed from the other yparts of the tool whenv the cap 82 is detached from the body 30. In practice the screwdriver may be advantageously formed from a single bar or rod by simply forming the flat screw-engaging part 45 at one end and the handle 117 at the other. n

The particular tool illustrated in the drawings is designed particularly to be used in operating the screw andl nut ofthe horn 10. When it is desired to adjustthe screw 17 the tool provided by the invention is arranged in the horn 15 in the manner clearly y illustrated. in Figs. 1 and l1.. The round portion 34 of the cap 31 engages the horn v15, centering the wrench 26 so that it accurately engages or fits over the nut 2O. If the wrench 26 does not fit over the nut 20 when the tool `is moved longitudinally into the horn it is merely necessary to rotate the tool,

thatA is, the frame of the tool, to bring the wrench in proper register vwith the nut 20,.

it being held in proper line with the nut 2O by the cooperation of the round part 34 of the cap 31 and the horn 15. When the wrench is in place on the nut 2O the screwdriver, being carried concentrically with the wrench 26, is in position to be moved into engagement with the screw 17. By turning the screwdriver to the proper position the flat screw-engaging portion 15 will enter the slot of the screw so that the screw can be turned. With the tool thus in place, that is,'with the wrench on the nut and the screwdriver in engagement with the screw, it is possible for the operator to simultaneously move both the screw and nut, to hold the screw and move the nut, or tohold the nut and move the screw. The wrench and screwdriver can be very easily and conveniently moved independently of each other, thus making it possible to operate the nut and screw independently of each other. When adjusting the horn 10 the screw is first held while the nut 20 is loosened, whereupon the screw is adjusted until the plate 18 is properly spaced from the electro-magnet, whereupon the screw is again held and the nut 2O is set or tightened. It will be obvious how the tool may be very easily and conveniently placed in the horn so that the nut is engaged by the wrench and the screw by the screwdriver, and how the ro )er ad'ustinv o erations ma be ver y easily, quickly, and accurately effected in a very convenient manner. It has been found in practice that it is not necessary to provide a handle on the frame 25 when the tool is to be used in connection with horns and the like. However, if the tool is to be used in connection with heavy machinery it may be found desirable to form the frame with a suitable handle in order that the wrench can be effectively operated.

In Fig. 5 we show the tool in position where the wrench is in position to operate lthe nut but where the screwdriver is not in engagement with the scre-w 17. ln Fig.

6 the tool is shown with the screwdriver in engagement with the screw 17, while the wrench is not in engagement with the nut 20. These twoigures of the drawings illustrate how the tool may be used tooperate either the nut or a screw whether or not ,they are in combination with each other fications that may appear to those skilled inthe art or `that may fallfwithin the scope if of the following claims.M
