I SAFETY. GATE.

Application filed octoberas', 1920. Serial no. 420,179.

To all whom it may concern:

Be it known that I, Gnoneii F. WINTER, a

citizen of the United States, residing at Los Angeles, in the county of Los .Angeles and State of California, have invented new and useful Improvements in Safety Gates of which t-he'following is a Specification.

This inventionis an improvement on the safety gate set forthinLetters Patent of the United States, No. 1,347,198, patented of the gate shown in Fig. 2, fully closed.

to me July '20, 1920, in which any edgewise moving closure for a passway is arranged to accommodate a limb of aperson so as'to avoid injury to such linibif thesame is'in the way whenthe closure is shut. An object of this invention isto provide a novel form of safety gate involving'the invention coveredby my saidpatent and to make provision wherebywhen the gateis closed, it forms as complete :a barrier at' the closure edge as at any :other part thereof; and to make'this true with respect to fire screen doors. 1

lVith this object in view I'pro'vide'the gate with a slide-way in" which I yieldingl'y mount a rigid edge member that is relatively light so that in case the gate is closed upon the body or upon it'lllllb, of a person, the edge member will allow the mainbody of the door to come to closedposition while the edge member is'in open position, without crushing or injuring the person, and to normally closethe passway when the path of'the gate is unobstructed;

This invention is applicable to grille work and wire glass elevatorgates and to analogous edgewise closures.

In this invention a comparatively'narrow and light section is slidingly or telescopically connected to a main body of the gate and is held yieldingly extended by resilient means, as springs or the like, socas to close the opening in conjunction with the main body ofthe gate. p

An object istoiorma complete passway closure without allowing the momentum of the main body thereof to' act to the injury of a limb orthe body of a person caught bythex gate inclosing.

Further objects, advantages and features of invention may appear from the accompanying drawings, the ,sirbjoined detail descriptionand the appended claims.

'The invention may be carried v out in various forms.

The accompanying drawings illustrate the invention in some of theforms 'inwhicli it may be applied. v

Fig. '8 is an enlarged fragmental sectional detail of the gate shown i'n'Figf'i.

fragmental section on line prising a main body 1 and a relatively movable edgewise moving section 2 which is normally projected beyond the edge of the closure by resilient means as the'springs 3; said section and spring means bothfbeing carried by the inain body 1' of t'he e'dgewise moving closure. 1 I Itis understood that the inventionmay be applied with an elevator having either a single or a double sliding closure.

In the form shown in Figs. 1-6, the: main body 1 is provided with a slide-way 4 at top and bottom in parallelism with each other andra side face of the door; and the movable section 2 is'provided with aslide oin each slide-way. The spring means 3 operatesupon the slides .5 to normally eX- tendthe. yielding 'section2 into position to complete the closing of thepassway or door opening'o. Where double doors are employed, one on each side of the passwayas shown in the drawings, one side of the 'passioo llO

way is closed by a door 7, and the other half of the passway is closed by the door 1 and yieldingly mounted sliding edge section 2 tended position, also looks the main body 1; there being a seat 9 in the frame of the main body which is engaged by the bolt when said main body gets to its closed position and while the yielding extension 2 is retracted by the interposition of any obstacle as an arm or a limb indicated in Fig. 4, is in the way; but as soon as the limb is withdrawn, the yielding section is extended by the resilient means 3 into passway closing position shown in Figs. 1, 2, 5, 7 and 8.

The extension 2 should be of as light construction as possible, due consideration being had to other conditions, so that when the elevator door is being closed by the usual pneumatic means, the momentum of the edge section 2 of the door will not be sufiicient to crush or injure the limb or other portion of a human being caught in the opening or passway 6.

The frame 10 of the yielding extension is rigidly connected to the slides 5 and fits snugly against the frame 11 of the main body 1; and the latch 8 is controlled by pneumatic means 12 which may be of any well known construction and engages the seats 9 and 13 when passway 6 is entirely closed. The operator of the doors will manipulate a handle 13 to control either the pneumatic device 14: or the electrical device 15 as the case may be to withdraw the latch from looking position when. it is desired to open the door.

16 indicates the structure forming the. sides, bottom and top of the passway, to which the closure is adapted.

Suitable means are provided to prevent the edge section 2 from being detached from the main section. 17 indicates detachable stops on slide members 5 working in slots 18 to limit the edgewise movement of the sections 2. I

I claim:

1. An edgewise moving closure for a passway, said closure comprising a main body to partially close the passway, and a section provided at one edge of said main body and being movable relative thereto; and means to yieldingly hold said relatively movable section extended beyond the edge of said main body to complete the closing of the passway; said means being adapted to allow said movable section to be retracted in case the limb of a person should interfere with of the main body of the closure.

2. An elevator door comprising an edgewise movable main body provided at one edge with a section movable edgewise relative to the main body; means to yieldingly hold said movable section extended from the main body to move said section into closed position to finally close the door opening, and also adapted to allow the main body of the door to move into its closed position without closing the opening in case the limb of a person should interfere with the movable section of the door at the closing operation; and means to lock the movable section of the door in closed position when the door is fully closed.

3. An edgewise moving closure comprising a main body having a slide-way in parallelism with a face of the closure; an edge section having a slide movable in said slideway; means to prevent withdrawal of the slides from the slide-way; resilient means to extend the edge member beyond the edge of the main body and to yieldingly hold the edge section extended.

1. An edgewise moving closure comprising a main body having a slide-way therein; an edge section having slides movable in said slide-way; means to prevent withdrawal of the slides from the slide-Way; resilient means to extend the edge section beyond the edge of the main body and to yieldingly hold the edge section extended; and means to lock said edge section in extended position.

5. An edgewise moving closure comprising a main body having a slide-way therein; an edge section having slides movable in said slide-way; means to prevent withdrawal of the slides from the slide-way; resilient means to extend the edge section beyond the edge of the main body; and to yieldingly hold the edge section extended; means to lock said edge section in extended position; and means under the control of the operator to release the lock from locked position.

'6. An elevator door comprising an edgewise movable main body adapted to partially close the door opening and provided at one edge with a section movable edgewise relative to the main body; means to move said movable main body to its closed position; and means to yieldingly hold the movable section extended from the main body to complete the closing of the door opening, and to permit said movable section to be retracted without interfering with the closing operation of said main body.

An elevator door comprising an edgewise movable main body adapted to partially close the door opening and provided at one edge with a section movable edgewise relative to the main body; means to move said movable main body to its closed position; sition when the door opening is'fnlly closed. means to yieldingly hold the movable sec- In testimony whereof, I have hereunto set 10 tion extended from the main body to commy hand at Los Angeles, California, this plete the chosing of the door opening, and to 18th day of October 1920. )ermit saic movable section to be retracted t ivithout interfering With the closing opera- GEORGE NVINTER' tion of said main body; and means to lock Witness:
