PICK-tir Fon FLAT IMPLEMniiTs.

Be it 'knoivn that l, RODNEY B. VARF., a citizen of the-United States otAmerica,

residing-at Springfield, inthe county of :Hampden andLState of Massachusetts, have inventeda new and useful Pick-Upffor Flat Implements, of whichthe following is a specification. j v

' [y invention relatesv to-'i-mprovements `in handles for fiat implements or objects, such as draftfsinans triangles and the like, and

"consists of a normally projecting device having its" ends mounted `in a slot'.- in the object to which it is applied,and capable of being collapsed' or compressed and thrust through such s lot, whereby the projecting .portions maybe presented on either` side this kind that can be projected on either `side of the implement with equal-facility,

and can also be Hattened so as not to increase thevspacefwhich the "implement should normally .o=.;upy for" shipment or when e. placed in a tool-,box or other' place of storyage,

it beingA possible to press said device entirelyfinto the ,slot providedv therefor and to retain ity therein with any suitable means of compression. An implement equipped wit-h this pick-upcan be usedeither side up in the customary manner, andwhen said im-V plement ispturned over the position 4ot the said pick-up is changed atgandduring the same time, consequently does not` cause delay or inconvenience. y,

' Other objects and advantages' will appear in the course of the following description. l I attain the objects and securethe advanr tages of lay-invention by the means'illus#` trated in .the accompanying drawings., in

' i Whichconstitutes the handle proper. In the Figure Alis-a plany oiia draiitsnians triangle equipped with a practical form ofthe I inventiomfFig 2,- an edge elevatiomof said "the latter lbeing trian le and the ick-11p g p lin ,ani lines and shown projected upwardl downwardly by dotted lines, the better Lto e.

ceding one, but here showing how the pick-l up may be pressed completely intothe triangle out of the way; Fig. 4, a plan of a portion of a drat'smans straight-edge or similar implement equipped with a modified form of said invention; Fig. 5, an edge elevation of the parts and members 'appearing i-n Fig. 4, the two projecting positions 'of the v pick-up being represented as in Fig. i2, and,

Fig."6, a cross-section taken on line AMB, in F ig. l.

Similar reference numerals designate similar parts throughout theseveral views.

The pick-up illustrated in the first three views is of the toggle-joint type, rwhile that illustrated in Figs. 1 and 5 is of the iexible- -strip type. `In these two ty es mechanical equivalents are employed, an there is there- Jfore no material di'erence in structure or function. In this connection 1t may be well to observe that my 4pick-up is susceptible of more or less change ,in other respects without departing from the spirit of the invention. This fact is obvious to one skilled in the art to which my invention appertains.

I have illustrated the new device in connection with or as applied to a triangle and addition thereto of a device of this kind.

In the drawings a triangle is represented at 6, and' a portion of a straight-edge at 7. There is ,a slot 8 in the triangle 6, and a .a straight-edge as concrete examples merely,

similar slot in the straight-edge 7. The lonv gitudinal edges of each slot 8 are provided with inwardly extending V-guides 9 and 10.

` lthe first pair being at the left-hand end of said slot and the second pair adjacent to the right-hand end thereof. i

v The pick-up in each example shown comprises a'l fixed end-piece 1, a movable endpiece orslide 2, and the'connecting element r'st example the aforesaid., connecting element-consists of toggle-joint'members 11 vand 12, and-in the second example such elenient consists of atiexible strip 13. The

members 11 .and 12 are pivotally connected at'contigliolis endsfby a `pin 14. and the outer ends of said viiriembers are pivotally and 16. Like the outer ends of the members 11 and 12, the ends of the strip 13l .orotherwise Each slidc2 is also provided in its longitudinal edges with V-grooves to receive one or the other pairs of V-guides 10, and such slide is sli pcd into place in the right-hand end of tlie slot 8 in which the companion end-lpiecel'l has been or is -4 to be located. A spring 3 has one terminal -pocketed in a recess that opens into each slot 8 at the right-hand end of the same, and

the other terminal oi' said spring is received in av recess in the slide 2 in said slot, the

` latter recess opening through the outer end of said slide. Thus it is seen that each slide 2 is pressed to the left or toward the companion end-piece 1. This movejmient is limited by two vertical pins 5 which are -ixed in the slide in such a Way that they eut across the V-grooves for the V-guides 10 and encounter the right-hand ends of said V-guides when said slide is left to the influence of its spring 3. Normally, therefore, the slide 2 of each pick-up is retained in what may be termed its forward position, and the toggle members l1 and l2 are projected beyon one surface (naturally,7 the p upper) of the triangle 6, in the one case,

and the strip 13 is similarly projected, in the other ease, the lengths of the parts in question being properly proportioned to enable the desired results to be produced. Necessarily 'the resistance of the strip 13 must be less than that of the associated spring 3, otherwise the device which consists in part of said strip would be' inoper- 4 ative.

There is clearance enough between the Aouter end of either slide 2, when the latter is thrust forward by its spring 3 as far as it can go, and the adjacent end of the slot 8 in which said slide is located to permit the members 11 and 12 (or the strip 13) to be straightened by being pressed come,

letely into the slot 8 from which said memgers4 normally project (or said strip normally projects), against the resiliency of the associated spring 3--see Fig. 3. Ordinarily the projecting members 11 and '12 will not thus remain straight in their slot without exterior'l conning means, but will spring out on one side or the other, and the same thing is true of the strip 13.

From the foregoing it is clear how, when the implement is turned o'ver, the yielding projecting element (the members 11 and 12 or the strip 13) is thrust into and through its slot and snapped out on the other side.

To facilitate the operation of changing the yielding projecting element from one side of the implement to the other, I provide such element with a slight projection on each side, a double-headed pin 4: being employed in each or' the present cases. In the irst device the pin 4: is inserted in the

member

1,1, and in the second device the pin 4 is inserted in the strip 13. i Upon turning either implement over :ind pressingit down on a firm fiat surface, the pick-u with which such implement is provided 1s not only forced'completely into itslt in a straight condition, but is forced by the part of its pin 4: that contacts with such surface above a straight line, when the compressed spring 3 immediately acts to throw the pick-up into operative position on the other side of the implement. This is a convenient and valuable feature of the in vention.

None of the pick-up members should be any-thicker than the -implement 6 (or 7), if said implement is to lie fiat when in use, and all of said members except the pin 4, are to be receivable wholly in their slot. The projecting parts of the pins 4 are so slight as not to interfere seriously when the piek-ups are compressed and the implements packed together or confined in close quarters.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a. flat object having a slot therein, of a pick-up comprising a handle element having its ends mounted in such slot, and relatively' movable toward and from one another, such element being adapted in its intermediate portion normally to project beyond either side of said object, without at the same time projecting beyond the opposite side.

2. The combination, with a fiat object having a slot therein, of a pick-up comprising an elementuiormally projecting from said object and mounted in said slot, and yieldin means to maintain said element in projected position.

3. The combination, with a iiat object having a slot therein, of a pick-up comprisin an element normally projecting from sai object and mounted in said slot, yieldin means to maintain said element inf-projected' position, and protuberances on both si des of saidf element which are adapted to throw said; element out of a straight line when forced into said slot and said object is pressed against aiiat resisting surface.

4. The combination, with a fiat object having a slot therein, of a spring-pressed slide mounted in said slot, and an element normally projecting from said object and piv- 13o mattei otally connected at one end to a fixed point in said slot and at the other end to said slide, the arrangement of parte being such that said element may be pressed completely into said slot or forced through beyond either side of said object.

5. The' combination, With a flat object having a slot therein, of a spring-pressed slide mounted in said slot, means to limit the movement of said slide, and an element normally projecting from said object and pivotally connected at one end to a ixed point in said slot and at the other end to said slide, the arrangement of parts being such that said'element may be pressed completely into said slot or forced through beyond either side of said object.

6. The combination, With a flat object having a slot therein, of a fixed member in one end of said slot', 4 a spring-pressed slide mounted in said slot adjacent to the other end thereof, and pivotally connected handle members having their outer ends pivotally connected With said fixed member and said slide, the arrangement of parts being euch that said handlemembers may be pressed completely into said slot or forced through to project beyond either side ot said object.

7. The combination,- With a iat object hav.- ing a slot therein, of a fixed member in one end of i said slot, a spring-pressed slide mounted in said slot adjacent to the other end thereof, pivotally connected members having their outer ends pivotally connected with said xed member and said slide, the arrangement of parts being such that said handle members may he pressed completely into Vsaid slot or forced through to project beyond either side of said object, and protuberances on both sides of one of said handie members, which protuberances extend beyond the planes of both major surfaces of said object When said handle members are disposed Wholly Within said slot.
