INVENTOR 1.4 "III A. ADELMANN COMBINATION TOOL Filed May 29 Www. i8, 3924.

Patented Nov.. i3, i924.

ALBREHT ADEL'MANN,

COMBINATION TOQL.

Application filed May 29,

To all whom t may concern.'

Be it known that I, Annnnorir ADELMANN, a citizen of Germany, residing at New York city, borough ot the Bronx, inthe county of Bronx and State of New York, have invented certain new and uset'ul improvements in Combination rlools, ot which the following is a specification.

This invention relates to combination im plements or tools and has particular ret'er` ence to hand operated tools for various uses such as spades, hoes, or picks.

Among the objects of the invention is to provide a tool having a suitable manually roperated handle tor manipulating the lhead portions thereof and having means associated with the handle for adjusting said head portions according to various functions or uses. Y

More specifically, among the objects ot' the invention is to provide a tool compris ing a handle, a head tor the end ot the handle, and a rigid. tool body so hinged to the head as to swing around an axis perpendicular to the aXis ot' the handle, said tool body carrying at one end a cutting blade which maybe used as a hoe, a spade, or the like, and having at the other end a pointed member in the nature oi", a pick and which may be used as a pick in one position and serving as a stili'ener or brace .tor the body 'in another position.

Another object ot theinvention is to provide for an adjustable tool ot the general nature set forth', manual means for adjust-r ing the tool members in the most rapid and convenient manner.

With the foregoing and other objects in view the invention consists in the arrange* meut and combination ot parts hereinafter described and claimed.` and while the invention, is not restricted to the exact details of construction disclosed or suggested here in, still for the purpose ot illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure l is a partial side elevation and partial central section ot my improved tool adjusted for use as a hoe and a pick, the section being substantially on the line 1 1 of Fig. 2.

Fig. 2 is a front elevation with parts in section.

Fig. 5 is a view similar to Fig. l, but showing the adjustment ot the tool ior use as a spade or other similar digger.

Fig. 8 is a tace view of the device in the position ot' Fig. 5 set for use as a spade.

Referring now more specifically to the drawings lt show my improvement as comprising a handle l0 ol' any suitable construction, design, or length, and fitted to it a tubular extension 1l preferably of metal, the same being shown attached to the reduced neck portion l2 of the handle and locked thereto by suitable screws 13 or the equivalent. The tubular shank portion ll ot the handle is provided along its front side with a bayonet slot ll having at its opposite ends angular extensions 1.4i and ldl tor locking purposes soon to be seen.

means including, for example, rivets 19.

This head includes laterally extending hubsV The principal active part of the tool comprises a body 2l of a strong substantial nature and having at one end a sharp tool or pick and at the other end a plate 23 to whicli is secured a cutting blade 24, as by means nl rivets rthe-parts 22 and 24- inay have any desired individual construetion or design. The means 'tor attaching the body 2l to the head includes a strong pivot pin 2G which projects througl'i the hubs 2O and around the ends ot which the ear portions 27 o't the blade 24; extend. The pivot pin 26 passes directly through the head 18 transversely. V

As a suitable means for swinging the body 21 around the axis of the pivot pin 26 l pr0- vide a pair ot links 28 connected pivotally at 29 to the body eccentric to the axis of the pivot 26, and at the other ends the links are pivoted at 30 upon a cross head 31 movable lengthwise along the shank 1l and in which is journaled a center guide 32 in the nature of a bolt, the head or neck portion of which is swiveled in the cross head and so is adapted to rotate through a short angle in addition tobeing movable bodily lengthwise of the handle. Fixed to the guide 82 is a collar 3 3, a set screw 34 passing through the slot 14 serving to bind the collar to the guide. The screw 34 constitutes a finger piece for manipulating the guide 32 both longitudinally and around its axis. The set screw 'furthermore serves as a locking means for co-operation in the angular extensions of the slot. The remote end of the guide is slidablev in the collar l5 and thus is maintained in its substantially central position. As will be apparent by comparison of Figs. l and 5, when the link pivot 29 is thrown upward or outward from the handle by movement of the set screw in such direction along the slot into registry with the eXtension 14a, the pick 22 will be projected from its bracing housed position and substantially at a Vright angle from the handle and the blade 24 will likewise be projected at an angle for use as a hoe. By rotating the guide pin 32 by bringing the set screw into the end of the angular extension 14a, the parts will be locked in such position and either the pick or the blade may be used according tothe immediate necessity. When the blade is to be used as a spade or other analogous digger, the operator simply unlocks the set screw 34 and slides it along the slot 14 until the angle portion 14b is reached where the set `screw is locked again at which Ytime the parts will be in the position ot Fig. 5 and locked for such use. The hub and

ear extensions

20 and 27 serve, therefore, not only as pivotal connections, but also as shoulders for the application of the operators foot in the use oit the tool as a spade.

The variation in adjustment means shown in Fig. 6 includes a center guide rod 32 con- Y nected as before described to the links 28 at a cross head 3l and extending all the way to the opposite end ot the handle 10 where it is screw threaded at 32a 'tor eo-operation with a rotatable linger piece in the term ot a nut 34 having a knurled head 35 journaled by means of a shoulder or collar 36 in the end ot the handle. This nut being thus held from endwise movement will canse the movement ot the rod 32 endwise when rotated and thereby the endwise movement of the links and the swinging ot the tool members as before described. The portion ont the guide adjacent to thc cross head is guided in collar l5 .'[ixed in the tubular portion et the handle. lu either 'Form ot the invention the

tool parts

22 and 24 are easilyv adjusted to dilferent angles 'tor various uses and the adjustment may be ellected quickly by finger manipulation', although the torni oi: the invention shown in the principal ligures is the one in which the adjustment is quicker than in the iorm shown in Fi 6.

l claim:

l. A combination tool crnnprising a han-A dle having a tubular shank portion` a head at the end ot the shank, a tool body connected b v a transverse pivot to said head at one side of the axis ot the handle, the shank being` slitted adjacent to the head at the opposite side Ytrom the pivot, a portion of the body being` movable around said pivot hrough the slit into the hollow shank, anY other portion o? the body beingl swinejable through an angle around said pivot and carrying a tool adapted 'for different purposes according to position, link means pivoted to the body eccentric to the pivot aforesaid, and manual means connected to the link means tor swinging the body around its pivot.

2. Mechanism as set forth in claim l in which a guide rod is connected to the link means and is movable endwisc along the handle and the manual means for adjusting` the body is associated with said guide rod.

3. A device as set forth in claim l, in which the link means comprises a pair ot links pivoted on opposite sides ot the body at one end and between which the portion ot the body that swings into the. tubular shank is adapted to nest in one position of the body.

4. In a combination tool, the combination of a handle having` a tubular portion, a head liked to the tubular portion at the remote end thereof, a body pivoted in said head tor movement around a transverse axis so as to bring one end ot the body within the tubular member, a pair ot links pivoted to the body eceentrieally ot the pivot aforesaid, manual means connected to the opposite ends of the links 'tor moving the same endwise ol' the handle and l'or causing the swinging ot the body. and means to lock the mannalhcontrolled means from accidental movement.
