Patented Dec. 2, 1930 UNITED STATES CHARLES VVI. MARKHAM, OF v'.LOLEDO,*OHIO TIMBER sPLIonR Application filed August 30, V1929. Serial No.'389,52`5.

This invention relatesto appliances for splicing timberstogether in end-to-end relation, and more particularly to devices of this character adapted for use in connection with the construction of concrete buildings.

The object of the invention is the provision ofa simple, efficient and inexpensive ldevice of the class described, which enables timbers to be easily and quickly secured together in end-to-end relation, and also separated when the `work for which intended is iinished, and which provides strong and durable splicing means for the timbers.

The invention is fully described in the fol- 5 lowing speciiication, andwhile in its broader aspect it is capable of embodiment in numerous forms, a preferredembodiment thereoil is illustrated in the accompanying drawings, in which- Fig. 1 is a side elevation ot' a device embodying the invention with timbers disposed in splicing relation therein and with the movable clamping member' in released position; Fig. 2 is a diilerent side elevation there- 25 of with the movable clamping member in timber clamping position;` and with parts broken awa-y; 3 is an enlarged `cross-section on the line 3 3 in Fig. 2, and Figlvt is an enlarged end view thereof.` 3U Referring to the drawings, 5 and '6 designate two timbers to splice, which timbers, particularly when used iny connection with concrete construction work, are usually square in cross-section, although other shapes l may be, and sometimes are, employed. v

The splicing means illustrated includes three band members 7 providing"substantially square openings, if the timbers to be spliced are square, and these members'are lined in substantially equi-distant relation along, what may be termed, stationary clamping member S. This clamping member is of L, or angle-iron form in cross-section and extends through the several bands 7, being set in and fitting one of the corner angles of each of the bands. The side edges of the member' 8, are shown as terminating short of the sides of the bands 7 toward which they project, although this is not necessary. The bands 7 are xed to the member 8 by CFI riveting', welding, or in any other suitable manner. i

Themovable member 9 of the clamp er:-l tends threugh-the bands 7 in transverse opposition to the lixed clam inv member 8 and is D 7 oi angular form in cross-section, corresponding to that of the member 8 so as to cooperate therewith to form a timber receiving passageway ot cross-sectional shape, substantially corresponding to that of the timbers.v

The member-9 is provided Aon the outer side of each leg portion thereof, and within each band 7, with one or more wedge block 10, all pointing in the same direction and adapted to coact with the respective sides of the bands 7 to force the member 9 toward the member 8 when the former is moved in one direction along the interposed member. Theclamping member 9 extends at its ends beyond the respective end bands 7, a sufficient distance to permit the member 9 to have the necessary lengthwise clamping and releasing movements relative to the bands 7 and stationary clamping member 8. The member 9 is provided at its opposite ends at the corner portions thereof, with driving blocks 11 and l2, the former, in the present instance,

being fiXedly secured to and connecting-the outerends of the adjacent wedge blocks 10 lat the respective ends of the clamping mem'- In order to facilitate the clamping action ofthe members 8 and 9 against the timbers to be spliced, the leg `portions of the member 8' are preferably provided with inwardly projecting spurs 13, which imbed themselves inthe surface portions of the clamped Vtimbers, providing -such timbers are of wood. One orlbothoi' the leg portions of the member 9 may also be provided with apertures 14 for receiving securing nails l5.

In' the use vof my clamping device, the timbers to be spliced have their adjacent ends inserted into -oppositeends of the splicing means between theclamping members 8 and '9; the member 9, during such action, being withdrawn to the right, inthe present instance, to move the wedge blocks 10 out of wedging coaction with the bands 7. The

ends of the 'timberspreferably meetwithin the center band 7, which is approximately in the center of the device. The timbers having been assembled within the splicing device in this matter, the operator strikes the right end of the clamping member 9 with a hammer or other suitable tool, the striking action being preferably against the block 11, thereby forcing the wedge blocks under the respective bands 7 and causing the timbers to be securely clamped between the members 8 and 9. To release the splicing means, it is only necessary to strike the left end of the clamping member 9, tor instance the block 12, with a hammer or other suitable tool. It is thus evident that my splicing means not only provides a very simple and strong and durable splice, but also is easily and quickly operated to either have clamping coaction with a pair of timbers or to be release(L therefrom.

I wish it understood that my invention is not limited to any speciiic construction, arrangement or form of the parts, as it is capable of numerous changes and modifications without departing from the spirit et the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A timber splicer having transversely opposed timber clamping members, which members are ot a cross-sectional shape to term timber receiving cavities which :tace each other and extending across the joint of timbers to be spliced, retaining` means encircling said members and permitting relative transverse and longitudinal movements of the members, and means on one of the members operable to cooperate with the retaining means when the associated member has lengthwise movement in one direction to Vforce the two members to have clamping coaction with any interposed timbers.

2. A timber splicer having transversely opposed timber clamping members, said members being of angular form in cross-section to receive opposing side portions of the timbers to be spliced, retaining bands encircling said members and iiXed to one of said members, the other member being capable of transverse movements relative to the bands, and wedge means movable lengthwise of the members and cooperating with the bands and movable member to cause the members to have clamping coaction with interposed timbers.

A timber splicer having a pair of transversely opposed timber clamping members cooperating to term an opening therebetween tor receiving timbers to be spliced, retaining bands confining the members and permitting them to have limited relative transverse movements, one ot said members being iixed to the bands and having timber piercing spurs projecting inwardly therefrom, and wedge means interposed between the loose member and retaining Vbands and operable, when nvsaeae moved in one direction lengthwise of the fixed member, to cause the members to have clamping coaction with interposed timbers.

4. A timber splicer having transversely opposed timber clamping members, retaining means for said members adapted to retain the members in assembled relation and one member being fixed to said means and the other member being` capable of transverse and longitudinal movements relative thereto, wedge means carried by the movable member tor coaction with the retaining means to fix the movable member toward the companion member when the movable member is moved in one direction lengthwise of the means, and means on the movable member for coacting with the retaining means to limit the lengthwise movements ot such member.

A splicer of the class described, comprisi ,L transversely opposed clamping members mounted tor relative transverse and lonl,.tuflinal movements and extending lengthwise ot the timbers to be spliced, a plurality of means encircling said members in spaced relation lengthwise thereof to confine the transverse movements of the members, and means on one side of said members cooperating with the encircling means to cause the rociated member to have opposed timber clamping act-ion with respect to the other member when the members have predetermined loi'igitudinal relative movements.

(5. A splicer of the class described, comprising transversely opposed timber clamping members mounted 'lor relative transverse and. longitudinal movements and extending lengthwise ot the timbers to be spliced across the joint thereof, a plurality ot' retaining means for said clamping members spaced lengthwise thereof, and wedge means on one ot said clamping members operable to coact with the retaining means when the associated member has longitudinal movement in one direction toV torce such member towards its companion.

In testimony whereof I have hereunto signed my name to this speciiication.

CHARLES M. MARKHAM.
