i CLAMP.

Application led January 28, `1922. Serial No. 532,458.`

To all whom t may concern Be it known that I, ELSAMUE S. FRENCH, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in clamps and more particularly to a clampadapted to be used for holding two pieces of material, the ends of which are to be joined by a. miter joint, the main object of vthe present invention being the provision of a clamp whereby the two piecesv of material to be clamped together may be moved apart, opening up the joint so that the glue or other adhesive material may be readily inserted within the joint and the joint then closed together tightly and retained in a rigid position while the glue sets or hardens.

Another object of the present invention is the provsion of a clamp of this character particularly adapted for holding articles which are to be joined together, especially articles which are disposed at substantially right angles to each other whereby the two articles are fitted within the movable clamping members and then brought'together so as to assure ofia perfect fit of the two partsy before the glue or adhesive material is ap-L plied thereto. After the fitlias been assured` the two members can be then readily moved apart for applying the adhesive materiall and returned to their close itting position and retained in this position until the adhesive material. hasy set.

A further object of the present invention 'is the provision of a. clamp of the above character which can be quickly and readily applied to articles to be joined together and detached therefrom, and which in itself isV extremely simple in construction yand operation and can be placed upon the market at a comparatively low cost.

v IVith theabove and other objects in view, theinvention consists in the novel features of construction, combination andv arrangement of-parts hereinafter more fully set forth, pointed out in the claims and shownv [in lthe accompanying drawings, in which:

Figure 1 is a top plan view of a clamp constructed in accordance with my in'veIi-l'y l tion, illustrating two pieces of material ar ranged within the clamp and' fitted tightly together; y.

Fig. 2 is a longitudinal sectional view taken through one of the clamping members onthe line 2-2 of F'ig. l; l Fig. 3 is a bottom plan View;y

line 4`4 of Fig. 3;

Fig. 4 is a transverse section taken on the Fig. 5 is a detail yplan view of the framesv and plates,

the melnbers being eliminated; y

Fig. 6 is a front elevation of a modifiedk form of clamp, and y l Fig. 7 is a side elevationv of the form of clamp shown in Fig. 6.

Referring now more particularly tor the i drawings, in which like reference characters indicate like parts of t ing members and as each of these members are similar in construction, it will only. be'.

necessary to describe the particular conhe device, the nu#4 I merals 1 and 2 indicate two similar clamp! struction of one member. Each of the l.,

clamping members comprises a body plate 3 havingformed upon one side thereof the frame 4 which when the body plates 'are brought together into overlapping relation,

as shown in Fig. l, are disposed at right angles to each other. These frame members are provided with longitudinal slots 5' adapted to receive the shank portionA 6 of a threaded sleeve 7, said sleeve'being-m'ovable within the channel 8 formedby the frame portion'4, the top of said frame 4 being sub-l stantially flat and preferably flush with the top of each of the `body plates 3. Formed portion 6 isv4 a. clamp-Q ing plate 9, and in oider to impartjmove.

integral with the shank ment to `this plate 9 so that the same'may be movedlongitudinally along y. the upper face of thev frame 4, ascrew 10" is threaded through the sleeve 7, one end of said screw being rotatably mountedy within the flange:

said channel. In order to impart movement to the screw l0, a finger piece 13 is formed upon the outer end of said screw member whereby `the operator may readily rotated the screw l() and move the'sleeve 7 alongthe v screw.

i Asillustrated in Fig. r1, the body plates 3k are provided with stationary clamping members 14 which are preferably disposed in alignment with the trames 4 so that when t the clamping members 9 are arranged within the trames 4 they will be disposed in alignment with the stationary clamping members 14. In order to insert the sleeve 7 through the top portion of the frames ,4, to a position within the channel portion 8,

a suitable opening 15 is formed in the top of each of the frames whereby the sleeve 7 can .be readily inserted therethrough then the screw 10 threaded through said sleeves and its reduced end secured within the bearing yformed in the flange 11 whereby the screw 10 may be manipulated to move thek sleeve 7 longitudinally within the channel 8 yand vcause the clamping member 9 to be y plates l3 toward this, one of l moved toward and away from the stationary closed prior to applying the yadhesive ma? terial theretoror after the adhesive ma terial has been applied.

Means are provided for moving the body and away from each other in order to apply the adhesive material to the endsof the strips which are to be securedl together, and in order to accomplish the body plates is provided with a straight slot (Figure 4) vin such a position that it will be disposed directly at right Aangles to the joint which is to be formed and moifable within this slot isl a tongue 17 v to,y retain the plates in their proper relative position, said tongue being retained within this slot by means of a plate 18 which is detachably connected to the tongue 17 by` means of the screws 19 and arranged upon the outer tacey or the plate in which the slot is formed, thus retaining the tongue 17 in its proper relative position within this slot so that the plates when movedy apart will movel in the proper direction.

vFormed integral with the under face ,of

i one of said plates, is a lug20 and connected to this lug is a'linlr 21, said link extending in the same general direction as the tongue 17 and connected to this link is an arcuate lever 22 which is pivoted to the clamping `member 2, vas at28, the yother end of the lever being pivotally connected as at 24 to a ,reciprocating rod 25. This rod 25 is mounted for sliding movement through the flange 26 formed on the clamp 2 whereby upon reciprocating movement of the rod 25 the lever 22 will be actuated upon its pivot body members 3 are then 23 to impart movement to the ylink .21 which will move the opposing body plate or clamping member toward or away from the clamping member 2, so that the two ends of the material to be joined together may be moved toward or away from each other.

In order to actuate the rod 25,11. cam member 27 is attached to the outer end ot said rod, said rod being eccentrically connected to said cam so that when thecam is inthe position illustrated in Fig. 3, whereby the major portion of the cam is contacting with the {iange 26, the rod 25 will `be moved outwardly, thus drawing thektwo clamping members tightly togetherL so that.

the pieces of material disposedy between the clamps 9 and 14 will have their ends tightly fitted together. Should it be desired to move the ends of the strips away from each other Jfor applying the adhesive, the

cam 27 is actuated throughr the medium ot the handle v28 so asto bring the minor portion of the cam next to the, flange *26,vr

causing the rod 25 tobemoved inwardly,

moving the link 2lgoutwardly4 and forcing the two vclamps away from each other. In order to assure a positive Amovement of "the two clamps, a coil spring 29 is pr ovided` one end of which is connected to a perforated ear 30 arranged at the` inner corner of one' of the vbody plates. and the other end of said springattached ,tothe inner end of the rod 25 wheiebyv the tension of said spring will tendto impart movement to the and the link 21 when the cam27` lever 22 is moved to thevposition shown in Fig. .5, From this it willl be apparent that after; the two pieces of material havebeen clamped between the two setsof clamping members 9yand 14 andc disposed at right anglesto each other so that the corners will be'brought into close proximity, when the two clamp-l ing members are in thefpositionillustrated in Fig. 5, the'ends of the pieces may beJ then brought tightly together' to assure ofia perfect tit or the miter joint by moving the camy member 27 lto'vtheposition shown in Fig.. 3. After the ends of vthe pieces *have been properly fitted together vand it is desired to apply they adhesive material, the' moved away from' each other, the movement being substantially perpendicular to the two pieceswhereby to provide suitable space between tlieends or thev pieces yfor applying the :adhesive: ma.- terial. After the adhesive material has been applied the joint is'then closed by .moving the two body membersbackfto their riormal positions, as illustrated in VFigg, .rietaining the ends ofthe pieces of material tightly together until the adhesiveinateri'al has hardened or set. 4 y

In order to retain the body members 3 in various adjusted positions with'respect to each other, the rod l25 is provided with a iis ist

plurality of notches 31 which are adapted to engage with the side of the opening through which the rod moves to retain the rod in various adjusted positions.

In Figs. 6 and 7, I have illustrated detachable jaw members indicated at 32 which may be detachably secured to the jaws 9 and 14:,

these jaw members 32 being provided with suitable slots 33, in which the lug 34 is adjustably mounted and retained in an adjusted position by means of the knut 25. These particular types of jaws are especially required due to the fact that many types of moldings and the like are constructed in two pieces, or of irregular shapes, the lug34 engaging the top of the molding to retain the same or the sections thereof in their proper relative positions, while the miter joint is being completed. These removable jaw members 32 may be detachably connected tothe jaw members 9 and 14 in any suitable manner.

I claim:

l. A device of the class described including two clamping members disposed at an angle to each other, means for causing said clamps to approach each other or separate along a path of movement oblique to said clamps, said means including a link connected with one of said clamps, a pivoted member connected tol the other of said clamps and having pivotal connection with y said link at one end and means connected to the other end of said pivoted member for imparting movement thereto,'as and for the purpose set forth.

2. A device of the class described including two clamps disposed at an angle to each other,means for causing said clamps to approach each other or separate along a path of movement oblique to said clamps, said means including a link connected to one of said clamps, a lever having pivotal connec-l tion with said link at one end, a movable.` rod carried by one of said clamps and having pivotal connection with the other end of the lever whereby movement of said rod Wllimpart movement to the rlever and in turn impart movement to said clamps and means for holding said clamps in various adjusted positions.

3. In combination, a pair of. clamps arranged at a fixed angle to each other, means for varying the distance between said clamps Without disturbing said angle, vsaid means including superposed frames slidably engaged with each other and projecting from said clamps into the included angle.

4. In combination, a pair of clamps arline transversely tothe first said line ofV movement. f

6. In combination, a pair of overlapping body plates capableof relativemovement in a right line, a clamp carried yby each of said members,'bothv of the clamps having mem'- bers capable of independent movement in right lines extending transversely to each other. f

In testimony whereof I ailix my signature.
