manner.

Application filed November 3, 1914.

the following is a full, clear, and exact specification.

This invention relates more particularly to a class of devices adapted to be used in buildings and like structures.

Our invention has for its object primarily to provide a device or opener designedto be employed in buildings and elsewhere which are constructed with skylights, air shafts, and the like having adjustable covers, doors,

or transoms whereby these parts, which are usually at inaccessible locations, may be conveniently raised and lowered for ventilating and other purposes, the invention consisting essentially of a lifting member, or bar having one of its ends pivoted to the cover, and this bar is movably disposed through a supporting casing so as to be directed to different positions for variably raising and lowering the cover as well as serving to hold the cover when in adjusted position.

Other objects of the invention are to provide means adapted to permit the bar to be manually moved from distances thereunder; to provide in the casing a cam operative retainer for holding the bar against movement when positioned; and to provide a rotatably movable weighted lever for operating the retainer.

A further object of the invention is to provide a scuttle cover opener of simple construction, and which is susceptible of being made so as to combine great strength and durability.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described hereinafter, and then pointed out in the claims at the end of the description.

In the drawing, Figure 1 is a longitudinal vertical section through a skylight with one form of scuttle cover opener embodying Specification of Letters Patent.

Patented Mar. 2, 1915.

Serial No. 870,075.

our invention applied thereto. Fig. 2 is an enlarged view, partly fragmentary, taken longitudinally through the casing of the device, and which shows a number of the operative parts thereof, and Fig. 3 is an en larged sectional view, partly in detail, taken on the line II-H of Fig. 1.

The device, or scuttle cover opener has a substantially rectan ular supporting casing 10 provided with two spaced parallel side plates 11 and 12 which are bridged by a top plate 13, and one end of both of the side plates are secured to the support, or base frame, as 1 1, of the cover, door, or transom, as 15, of a skylight, air shaft, or the like of a building, .or other structure, the cover belng hinged, as at 16, to the base. As shown, the casing 10 is positioned to extend interiorly of the base frame 1% from a part thereof which is under the free end of the hinged cover 15. The bridging plate 13 is considerably shorter than the side plates 11 and 12, and this bridging plate is spaced some distance from the free ends of the side plates. Extending from the lower part of the side plate inwardly of the casing is a flange 17 of a similar length to the bridging plate so that the outer end of this plate and the flange are on alinement. Between the free ends of the side plates 11 and 12 is a plate 18 having its inner edge curved, at 19, and this plate is of a width whereby its curved edge is'spaced from the opposed ends of the bridging plate 13 and the flange 17 In this manner a passage 20 is provided through the casing while the curved edge 19 of the plate 18 and the opposed ends of the bridging plate 13 and the flange 17 serve as a guide for a lifting member, or bar 21 which is movably disposed through the passage 20 of the casing 10.

The lifting bar 21 is preferably slightly curved, and this bar may be of any desired length. The upper end of the bar 21 is pivoted, at 22, to the cover 15 at a part thereof opposite to its hinged end, and to the lower end of this bar is connected by a hook or otherwise one end of a line, or cable 23 serving as means to permit the bar to be manually moved, as will be hereinafter more fully explained. The line 23 is guided over a pulley 24: which is rotatably held between the side plates 11 and 12 of the casing 10, and the cable is then allowed to hang a suitable distance below the device and un- 21 forholding' this bar against movement by fder the cover 15 so as to be accessible .for operation especially as these covers are generally located atunusual heights. The other end of the cable 23 is attached to one end of 5 a rod,or lever '25 having a ball, 'or weight as 27, on its-other end. Theweighted lever 25 is held interniediatejts ends to a short shaft 28 of a cam actuated retainer, 29

y adapted to hold the lifting member, or bar 10 28'against movement when adjustedfin positionin the passage of'the casing 10, the "shaft being journaled intheside plates of this casing.

, V The cam actuated retainer consists of I 1'5 a circular disk 30 'eccentrically fixed on the adapted to engage the bar, and to'limit the- ,,-'imo nt of. the pawl, or toothed block 31 .330 when forced direction from the bar 21 projecting interiorly' of the casing 1 0 from spaced; parts of' its side'pla'te'12' are two alinedstops, as 35 and 3.6. a The pawl, or toothed block '31 is normally held into engagement with, the liftingbar the weight 27 of the lever '25 tending by,

reason of its automatic downward movement 'to revjolve the shaft 28 andjithe cam disk 3 0; for forcing the pawl into contact with the bar 21, and when the device is operated, for instance, toraise the cover 15 the part ofthe line 23 which is attached to the lever 25 is manually guided to move the weight 27 of the lever in an upwardly direction. The shaft '28 and the eccentrically 'revoluble cam 30 will thereby 'be revolved to force the pawl 31 free from its engagement with the bar 21 and against the stops I35 and 36; By then directing the part of the line which is .guidedover thepulley '24 and which is attached to thelower end of the bar 21 also in a-fclownwardly direction this bar will be moved upwardly in the passage 20 of the casing 1Ov for swinging the cover 15 on its hinge to, a: suitable open position. When the line 23 is released the weight '27 will automatically vmove in an opposite di rection, and the shaft '28, the cam 30, and the pawl 31 will be reversely operated'so that the pawl will Joe-forced into engagement with the bar 2'1which in turn will be held against 7 accidental movement to hold the cover in an open position. By subsequently '65 pulling the line 23 to operate the lever base at which time the bar 21 will be moved bodied the preferred form of our invention,
