SPECIFICATION forming part ofLettersiPatent No. 704,884, dated July 15, 19,02. Application filed liovember 25, 19 01. san No. 33,635. (No man.)

Tov all whom, it may concern:

to the accompanying drawings;

This invention relates to scaffold-splioers,'

the. object in view being to provide a simple I device of the character referred to bymeans of which the poles or standards of a scafiold may be extended by utilizing additional seetions, which are placed end to endvertically and one upon the other, the said splicing device serving to elfectually couple and lock the adjacentends of the pole-sections -together,;

provision being made-atthe same time for receiving and holding the adjacent parts 'of the ledgers and putlogs. The construction ently of the iedgers and putlogs', as maybe nec essary. r

With the above andother objects in view the invention consists inthe novel construction, combination, and. arrangement of parts hereinafter fully described, illustrated, and claimed. V

In the accompanying drawings, Figure 1 is a perspective View showing the scaffold-splicer in position upon the adjacentends of a pair of pole-sections, also illustrating the manner Fig. 2 is Fig.

of supporting a putlog and ledger. a vertical sectional view of the splicer.

'3 is a perspective view of a simplified form of scafiold-splicer, showing the same applied to pole-sections, oneof which is indicated in I positely-located side walls which are preferably formed integrallywith the back'wall.

The frame or sleeve forming the body of th'esplicer is made of suitable length to embrace the adjoiningends'of a pair of pole-sections 4: a sufficient distance to obtain-the necessary hold thereon andlat or near the centerth'esplicer is;provided with a transverse partition or shelf 5, whichforms an abutment forihe adjacent ends of the pole-sections, as

fclearlyf indicated in'Fig. 3; i In order to brace and lock the ends'ot the polesections, the frameof the splicer is. provided at or near its topand bottom with oppositely-located pairs of eyes 6, each-pair-being designed to receive a removable retaining-pin 7. The

pins 7 serve to hold the pole-sections within the frame at points remotefrom the extremities of the sections, while the'e xtremities are held in place and prevented from moving by means of a third retaining-pin 8, which is preferably rectangular'and fiat in cross-secpoints on the'open side of the frame of the splicer. Each of the pins 7 and 8 is by preference permanently connected or anchored to the frame of the splicer by means of a chain or other flexible connection 9, and in order that each pin may-be efiectively retained in 'place l'provid'e a pin or cotter 10, which by preference is also: anchored by a suitable flexible connection 11 to the frame of the .splicer; The intermediate retaining-pin 8 is .insertible through oppositely-located eyes 12, formed integrally with the frame and of a shape adapting themto properly receive said pin 8.

In order to adapt the splicer to receive and support a putlog 13 and a ledger 14, the back wall 1 of the splicer is formed with an opening 15 of sufficient size to receive theputlog, which extends therethrough in the manner shown in Fig. 1. Where the putlog is used, it forms a support for the lower extremity of the next succeeding upper pole-section 4, which is held by the splicer. In this case it is also necessary to provide an additional re .tion and of greaterjwidth' than the thickness taining-pin 15, removably inserted through oppositelylocated eyes 16 just above the plane of the opening 15 and at the open side of the frame, as clearly shown in Fig. 1.

Below the partition 5 and at the front side of the frame is arranged an upwardly-extending ledger-holder 17 in the form of a hook, terminating at its upper edge below the upper surface of the partition 5, as shown in Figs. 1 and 2. The base of the hook or holder 17 extends inward to a point in line with the edges of the sides 2 and 3 and forms ashoulder or abutment 18, against which the upper portion of the lower pole-section 4 abuts. The ledger 14 merely rests within the hook or holder 17 and lies beneath the putlog 13, as illustrated in Fig. 1.

The scaffold-splicer hereinabove described is simple and inexpensive in construction and will be found of great convenience in splicing the sections of poles or standards in scaffoldbuilding, the splicer being at the same time adapted to form an eflicient support for the putlogs and ledgers. It is not necessary to slide the pole-sections into the ends of the sleeve or frame forming the splicer; but said pole-sections may be introduced laterally or the splicer itself maybe adjusted laterally to the adjacent ends of the pole-sections, thus greatly facilitating the building of the structure.

I do not desire to be limited to the details of construction hereinabove described, and illustrated in the drawings, and accordingly reserve the right to change, modify, or vary theconst-ruction within the scope of the appended claims.

Having thus described the invention, I claim as new- 1. A scaffold-splicer in the form of an opensided sleeve or frame adapted to embrace the adjacent ends of pole-sections, and retainingpins removably inserted through eyes at the open side of the sleeve and adapted to form abutments for the adjacent sides of the polesections.

2. A pole-splicer in the form of an opensided sleeve or frame adapted to receive the adjacent ends of pole-sections, a partition or shelf arranged intermediate the ends of the sleeve and forming an abutment for the ex-' tremities of the pole-sections, and detachable retaining-pins extending across the open side of said sleeve or frame.

3. A pole-splicer in the form of an opensided sleeve or frame adapted to embrace the adjacent ends of pole-sections, a partition or shelf arranged intermediate the ends of the splicer and forming an abutment for the extremities of the pole-sections, detachable retaining-pins extending across the open side of the splicer at or near the opposite ends thereof, and an intermediate retaining-pin extending across the open side of the splicer and arranged to project above and below the partition so as to engage the extremities of the pole-sections.

4. Ascaffold-splicer in the form of an opensidedframe provided intermediate its ends with a transverse partition and provided with a putlog-opening extending through the rear wall thereof at one side of the partition, and detachable retaining-pins extending across the open side of the splicer for preventing lateral displacement of the pole-sections.

5. A pole-splicer in the form of an opensided frame or sleeve adapted to embrace the adjacent ends of pole-sections, a transverse partition located intermediate the ends of the splicer and forming an abutment for the extremities of the pole-sections, detachable retaining-pins extending across the open side of the splicer, anda ledger-holder in the form of a hook located to one side of the plane of the partition.

6. A scaffold-splicer in the form of an opensided frame or sleeve, a transverse partition located intermediate the ends of the splicer,

detachable retaining-pins crossing the open side of the splicer at or near its opposite ends, and a ledger-holder extending across the open side of the splicer and forming an abutment for one of the pole-sections.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN LALLY.
