Specification of Letters Patent. Patented Apr, 11, 1 916.
Application filed Jul 8, 1915. Serial No. 38,797.
To all whom it mag concern Be it known that we, WILLIAM F. MAUV is the providing of auxiliary safety doors which will prevent the accidental stepping of a person into an open shaft, or the accidental dropping of goods down the shaft while the outer doors are open, and at the same time afi'ording ample ventilation and preventing rodents from entering the shaft. Our .door feature may, of course, also be used independently of any elevator. We obtain this and other objects of our invention by combining with the shaft, outer and inner doors, covering the latter. with screen, and using for our purpose the combination of parts hereinafter fully described.
In the accompanying drawings, constituting a part of this specification, Figure 1 is a vertical section on the line 1--1 of Fig. 2, showing an elevator pit or shaft extending from the sidewalk to the basement; the top of the shaft being provided with inner and outer doors of our invention, such doors being shown in their lifted position in dotted outline, and the elevator being shown in both its up and down position, the former being indicated in dotted outline. Fig. 2 is a top view of the elevator shaft looking down on the sidewalk-with the outer doors removed, and the inner screen doors being shown as closed. Fig. 3 is a vertical section taken on the line 3-3 of Fig. 2, and, Fig. 4L is a similar section taken on the line 4.4 of Fig. 2.
a represents the sidewalk, b the floor of the basement, 0 the vertical guide-ways or posts, cl the elevator floor, e the uprights of the frame mounted on the elevator the top of such frame members 6 being united by a curved or bow-piece as shown at f. i
g 9' represent a pair of screened inner doors which are connected by hinges g to the metal frame it, set in the sidewalk at the top of the elevator shaft. The inner doors 9 g are provided with slots z, and on the bottom of thesedoors there is fastened a fiat strip of springmetal j (see Fig.4)
which yieldingly bears against the guideways a permitting thedoors g g to be opened andclosed over the top of such guide-ways,
butjat the same time constantly keeping the 7 WIL IAM F. MAN AND HANs o. ANDERSON; or PORTLAND, OREGON, ASSIGNORS or slots 2' closed so as to prevent rodents from entering through slots when the outer doors 7: 7c of the elevator are opened, and the inner doors closed. Angle members g fixed on the inner door 9, are adapted to engage the sides of the metal frame it, when said doors are closed so as to hold the doors from falling into the shaft. 1
Theouter doors k are connected by, invisible hinge-arms Z to said frame h, and such hinge-arms project through the slots on therefor provided in the inner grated doors. On the under side of the latter are provided yielding straps n which normally 7 is on the doors while the elevator is about a to be lifted. When the outer doors are opened by means of the frame 6, provided on the elevator, accidents are liable to happen. When the outer doors are open, they are connected'by across-bar 7c. The inner doors 9 g are sohinged as to beopened and closed by the raising and lowering of the elevator and to rest against the standards of the frame 6, provided on the elevator, while the latter is being raised and lowered, and while remaining in its up position; all of these features being fully shown in Fig. 1. Wearing strips g are provided on the lower side of the inner doors 9 9 against which the curved frame member f'bears when the elevator 1s raised, Where our door feature is to be used independently of an elevator, the slots 2' and the related resilient pieces j are of course, omitted.
lVe claim:
'1. The combination With a shaft, of an inner pair of screen doors provided with slots, an outer pair of doors hinge-arms for the latter, such hinge arms projecting through said slots provided therefor in said screen doors, and resilient members on the latter covering such slots, yieldingly bearing against said hinge-arms.
2. The combination in an' underground elevator of the character described, of an upright frame on the elevator, such frame provided With a curved top, an inner pair of doors provided with slots and hinged so as to be lifted and lowered by the raising and lowering of the elevator, an outer pair of doors, hinge-arms for the latter, such hinge-arms projecting through said slots provided therefor in said inner doors, and resilient members on the latter covering said slots, and yieldingly bearing against said hinge-arms.
3. The combination in an underground elevator of the character described, includ ing vertical guideways, an outer pair of doors, and hinge arms for the latter, of an upright frame on the elevator, such frame provided with a curved top, an inner pair of doors hinged so as to be lifted and lowered by the raising and lowering of the elevator, such doors provided With slots for the vertical guide-Ways, slots for the hinge arms of the outer doors, and resilient members on the inner doors covering said slots and bearing yieldingly against said guide-Ways and hinge-arms respectively.
