KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die den Gegenstand der Erfindung bildende Gleitschutzvorrichtung besteht aus einem mittels einer Kette an einer Leitersprosse zu befestigenden Anker. Dieser Anker besteht aus einer einerseits in einen Ring R, anderseits in einen Griff G auslaufenden schmiedeeisernen Stange S mit einem spitz auslaufenden Dorn D, dessen dem Ring R zugekehrte Seite nahezu geradlinig (ganz schwach konkav) und senkrecht zur Stange S ist, während die vom Ring R abgekehrte Seite stärker gekrümmt ist. Da, wo der Dorn D in die Stange 5 eingelassen ist, ist letztere zu einer kleinen Platte, P erweitert. In dem Ring R ist eine eiserne Kette befestigt, mit einem Haken H am andern Ende, der in die Kettenglieder eingreifen kann.The anti-skid device forming the subject of the invention consists of an anchor to be attached to a ladder rung by means of a chain. This anchor consists of a wrought iron rod S , which ends in a ring R on the one hand and a handle G on the other, with a pointed mandrel D, the side of which facing the ring R is almost straight (very slightly concave) and perpendicular to the rod S , while the one from Ring R is more curved on the opposite side. Where the mandrel D is embedded in the rod 5, the latter is expanded to form a small plate, P. An iron chain is attached to the ring R , with a hook H at the other end, which can engage the chain links.
Beim Gebrauch wird unterhalb der zu haltenden Anlegeleiter durch Treten auf die Platte P der Dorn D in Zwischenräumen des Pflasters oder der Trottoirplatten usw. hineingetrieben, die Kette um die Mitte der untersten Leitersprosse geschlungen und bei straffer Spannung der Haken H in ein Kettenglied eingehakt. Dann kann die Leiter auf glattem Boden nicht ausgleiten. Statt einer Kette können auch zwei verwandt werden, die dann an den Enden der Sprosse zugleich um diese wie um den Holm der Leiter gelegt werden. Statt Ketten sind auch Gurte mit Hakenlöchern brauchbar. During use, the spike D is driven into the gaps between the pavement or the sidewalk, etc. below the leaning ladder to be held by stepping on the plate P, the chain is looped around the center of the lowest rung and, when the ladder is tight, the hook H is hooked into a chain link. Then the ladder cannot slip on smooth ground. Instead of one chain, two can also be used, which are then placed around the ends of the rung at the same time as around the stile of the ladder. Instead of chains, straps with hook holes can also be used.
Das Herausheben des Domes erfolgt mittels des Griffes G. The dome is lifted out using the handle G.
