* fram of the bolts;

Patented Nov. 23,1943 Y iframes. Itis partic ularltffA directed, to" a clamplwfor repairing doors, screens, 'sa's'hf'a d the likearticles."

A n object offthisjjinvention is to providefa Clamp 1f1.f11"f.1r4'elle*i115fllle` Sfw .engage Opposite suriacesof the door', scre'eiijsa'shjdr other article to be repaired, andmeans to draw the, clamp eleirl-ents together-,fthe clamp elements beingjprovided with prongs orteethadapted to draw to` gether the split portions of the ,article to be revAnother object of this inventionis to provide in a clamp of the character described, ribs on one or more of the clamp elements to strengthen the same and add to the appearance thereof, and also to put a spring tension on the bolt which interconnects the clamp elements.

Yet a further object of this invention is to provide in a'clamp of the character described, clamp elements having conical countersunk portions and a bolt interconnecting said clamp elements having a conical head adapted to be received in the countersunk portion of one of the clamp elements, and a conical nut received in the conical countersunk portion of the other clamp element. y

Still another object of this invention is to provide a strong, durable and compact clamp of the character described, which shall 'be easy to' apply, which shall be relatively inexpensive to manufacture, and yet practical 'and eicient toa high degree in use.`

Other objects of this invention will in part be obvious and in part hereinafter pointed out;

The invention accordingly consists Vin the fea-- tures of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claim.

In the accompanying drawing, in which is shown various possible'illustrative embodiments of this invention,

Fig. l isa top plan View of a flush type clamp embodying the invention, applied to a board or a sliding door;

AFig. 2 is a cross-sectional View taken on line rfients, 'and illustrating a modified construction.-

Referring now in detail to the drawing, `I"0 designates a board whijclima'y bepartof a door, o ij sashframe which iras 'agen'erally longiL the board It if it has a split S running through 2,-2 of Fig. 1, showing both flush and ribbed type;

Fig. 6 is a partial, end View of one of the clamp elements; and

Fig. 7 is an end View of one of the clamp elethe board III.

Member I2 comprises a substantially flat plate made of metal, having a central longitudinal portion I5, from which there extends a plurality of parallel spaced pairs of oppositely extending, aligned arms I6. Thus, one pair of arms is disposed at the upper end of the longitudinal portion I5. One pair of arms is located at the lower end of said longitudinal portion, and one pair of varmsis disposed mediately the ends of the longitudinal portion I5.

Any suitable number of pairs of arms I6 may be provided. The ends of the arms maybe vcurved, as at I'I, as illustrated in the drawing. Each of the arms is formed with a substantially conical countersunk portion I8 formed with a central opening I9. Furthermore at the top and bottom edges of each arm I6, is a prong 2|) disposed at right angles to the plane of member I2.

Member I3 Vis likewise made of sheet metal, and has substantially the same shape as member I2. It is -formed with a central longitudinal portion 23 and spaced, parallel pairs of oppositely extending arms 24. The arms 24, as well as the longitudinal portion 23, however are pressed outwardly along the central portions thereof, forminglongitudinal ribs 23a and transverse ribs 24a. As shown inthe drawing, around the edges of ribs 23a, 24a, are flat portions 23h, 2Gb which contact one surface of the board. Y At the ends of arms 24 are also conical countersunk portions 30 formed with central openings 3I, similar, and symmetrically disposed with respect to the countersunk portions I8. At opposite sides of each of the arms 24, are also prongs 421 perpendicular to the plane of member I3.

It will be noted that the clamp members I2 and I3 areapplied to opposite sides of the board IIJ,

They are so placed that the prongs 2U, 21

tersunk recesses lois drilled with through openings sa aligned with rthe openings I9 and 3I of clamp elements I2, I3,.

and at the ends of through openings 33, are counl y 35 and 36 to receive conical portions I8and 30. e Y QV Bolts YI4 pass through the'bolt openings 33. The bolts I4 have conical heads Ma received within the countersunk portions 30 of member I3. Screwed to the shanks of the bolts are conical heads orrnuts 40 received Within the countersunk portions 'I8k of clamp elementr` I 2. v The prongs serve to draw together the portions 'ofthe board I0 on opposite sides of the split S. The l.

nut 40 may be formed with a Vkerfll so that either the nut or the bolt may be turned withY a: yscrew driver to tighten the bolt.

' In Fig. 4 there is shown a clampnembervai -f similar to member I3, except thatfit onlyhas two pairs of outwardly Vextending arms instead of three pairs, as shown inl Fig. 3. Otherwise,"tl`1e Y' clamp element I3a is the 'same as clamp ele- Itgwiu rnewV be yrmtetiethat the vrits, :sana

strngthenclamp element YI3 and'add to the vappearance thereof, and' also' provide. resiliency which aids in keeping the bolts from comingVA out.

. In Fig. 7 thereis, shown amodied constructionin whichthe prong'shll have vertical, outer edges 5I and inclined,.inner edges V52 to aid inV drawing together the parts of ythememberto be repaired whlch areon opposlte sides o f the split;
