Figure 1 of the drawings is a section showing one of the floor pieces in their normal state,- Figure 2 is a vertical section showing one floor piece raised; Figure 3 is a top plan; Figure a is a bottom plan; and Figure is a vertical section showing a modification.

The numeral 4 marks an elevator raised and lowered by any suitable means 5 on guides 20 in a shaft 3 in a building 1, the numeral 2 marking one of the many landing floors that the elevator may pass.

The elevator 4 has an upwardly movable floor section 6 connected byhinges 7 with the floor of the elevator, and the floor 2 has an upwardly movable section 8 connected to the floor by hinges 9. The

floor sections

6 and 8 may be angle members having depending flanges that bear, respectively, against theyedge of the floor of the elevator 4 and against the edge of the floor 2 in'the building 1, to take some of the strain of? the hinges 9 and 7. Under the floor section 6 is located a guard or signal strip 10 that is hinged at 11 to the floor of the elevator for upward swinging movement. Flexible elements 12, connected to the ends of the guard 10 and to the floor of the elevator 4., hold the guard 10 in a. horizontal position, against clownward swinging movement. The guard 10 is made out of light material, such as wire netting. A like guard or signal strip ltis hinged at 15 to the floor 2 of the building 1, under the floor section 8, and is sustained from the floor 2 by flexible elements 16 connected to the guard and to the floor.

It a person stands in the elevator 4 with his foot 19 in protruding position, the guard 14 and the floor section 8 will swing upwardly without injury to the foot, when the elevator t moves up past the floor 2. If a person is standing on the floor section 8fw-ith protruding-into the shaft 3, the guard 10 and the floor section 6 will swinghis foot sons' foot will not be injured. The light str1ps 10 and l4'often give a particularly good feature-if, when the foot 19 sticks out, as in ;F igure 2, there happens to be a weight ofsomekind on the movable-section 8. The same argument holds it-the foot protrudes beyondthe section-8;there being a weight-ofa y sort in the elevator 4, onthe movable section 6.-

' Incl sired, toredu'ce the weight that-the-protrud I mg toot has to raise. In Figu-re5, parts here inb'efore described have been designated by up, "as the elevatoii moves down, and the per-- person a warn ing signal in time so that; he can jerk'backhis footwithout; having to raise-the floor section 6, or the floor section 8-. This is a.

fll r "l'fTnimp1( :*'v'en'ient's i in L elevator construction, a landing and an elevatormovable'vefl tically with respect to the landing, each including a fixed floor seotioma movablefloor section hinged to. one of thefi-xed floor. sections for .upward swinging movement, and asignal strip located below the-movable floor section and hinged to the said fixed :floorsectio-n. for upwardswinging movement, thesignal strip being. lighter-than the-movable fioorsection, whereby the saidstrip. will strike a protruding foot and afford a warning signal before the foot comes into contact with the movable floor section, the movable floor section lying above the signal strip to protect the signal strip against injury during the movement of passengers and goods to and fromthe elevator.

2. In improvements in elevator construction, a landing and an elevator movable vertically with respect to the landing, each including a fixed floor section, an upwardly 'foldable hinge mounted on the upper surface of one of the fixed floor sections, and a movable floor section made up of an angle member comprising a substantially horizontal flange attached to the hinge, and a substantially vertical flange extending downwardly along the edge of the said fixed floor section, to serve as a reenforcement for the hinge.

3. In improvements in elevator construction, a landing and an elevator movable Vertically with'respect to the landing, each including a fixed floor section, an upwardly foldable hinge mounted on the upper surface of one of the fixed floor sections, a movable floor section made up of an angle member comprising a substantially horizontal flange attached to the hinge, and asubstantially vertical flange extended downwardly along the edge of the said fixed floor section to serve as a reeniorcem ent for the hinge, and a compression spring housed in the said fixed floor section and located underneath the hinge, the

springcooperating with the hinge to aid in raising the movable floor section when an object is engaged therebeneath, as the elevator moves vertically with respect to the landing.

4. In improvements in elevator construction, a landing and an elevator movable vertically, with respect to the landing, cachincluding a fixed floor section, an upwardly foldable hinge mounted onthe upper surface of one of the fixed floor sections, a movable floor section made up of an angle member comprising a substantially horizontal flange attached to the hinge, and a substantially vertical flange extended downwardly along the edge of the said fixed floor section to serve as a reenforcement for the hinge, a compression spring housed in the said fixed floor section and located underneath the hinge, the spring.

cooperating with the hinge to aid in raising the movable floor section when a protruding foot is engaged therebeneath, asthe elevator moves vertically with respect to the landing, and a signal strip located below the movable floor section and hinged to the said fixed floor section for upward swinging movement, the signal strip being lighter than the movable floor section, whereby the said strip will strike a protruding foot and afi'ord a warning signal before the foot comes into contact with the movable floor section.

In testimony that I claimcthe foregoing as my own, Ihave hereto afiixed my signature.
