UNITED STATES PATENT OFFICE HOISTING MEANS Adolph Keller, Glendale, Mo.

Application December 13, 1943; SerialNo. 514',013

15 Claims.

My invention relates to hoisting means and more particularly to one for use with building windows.

One of the objects of my invention is to produce an improved portable hoisting means which can be quickly and easily attached to a building window structure and employed for lifting articles, such as storm windows, to and lowering them from an upper story. I

Another object of my invention is to produce an improved hoisting means, including a hoisting device, which can be fastened to a window sash for lifting and lowering a storm window, said device being so arranged that the pulley carrying projecting part can be movedout of the way during installation of the storm window on its hangers and its removal therefrom.

Still another object of my invention is to provide improved means for association with a window sash and a window frame for raising and lowering a storm window and for supportingflit adjacent the window during the hanging and unh'anging operations.

A still further object of myinvention is to provide portable-means for aiding in the installation and removal of storm windows which is simple in construction, economical to manufacture, and easily and safely usable in order to save labor and prevent damage.

Other objects of my invention will become apparent from the ir'ollowing description taken in connection with the accompanying drawing in which Figure '1 is a view showing my improved hoisting and supporting means as associated with a building window when being used as an aid in installing or removing storm windows; Figure2 is a sectional view taken on the line 2-2 of Figure 1 but showing the storm window resting on the supporting means; Figure 3 is a top view showing details of the pulley and its manner of mounting on the outer end of the arm of a hoisting device; and Figure iisa view of a modified hoisting device.

Referring in detail to the drawing, myhoisting means comprises essentially three elements, namely, two like hoisting devices A and B and a supporting means C. The hoisting devices A and B are adapted to be mounted on the window sash frames and the supporting means C is adapted to be associatedwith the sash and the bottom of the window frame where it'is held in'position.

Each hoisting device comprises a U-shaped bracket I having'a base portion 2 and legs3and 4. As shown, the bracket is made of wood with the base portion and legs comprising separate members secured: together by. suitable means, such as: nails or screws.v Associatedxwith the bracket is an arm 5. shown as formed of :three wooden members 6, l, and 8 arranged in the shape of a right-angle with members at and 8 positioned at. right-angles to each. other "and member connectedbetween themembers Sand :8 and arranged to form the brace of the arm.

The armis' pivotally connected to bracket l' by-a hinge 9, said hinge being connected 1170 the base member 2 of the bracket andmember 6-of thearm .so that/the arm canassume a position wherethe member 8 cooperates with leg 4 of the bracket and extends 'outwardlyfrom the bracketas; shown in Figures 1 and 2. The "hinge. connectionpermits the arm toz-be swung about the-bracket to a position where'the armwill overlie thebase of the bracket, that is, memberB of .the arm and the basemember 2 of the bracket will be injuxtaposition. The outer end of thearm attheil'uncture of the-membersfi and l carries a pulley Ill which is positioned in a slot II, the pulley being journaled on a bolt I12; A metal rerenforcing member I3 is positioned over the joined ends of members 6 and 1 and thus'maintains thesemembers together and also providesa wear resisting bearing for the bolt I2. the pulley and has a snap l5 secured .to oneend.

When devicesA and Bare to bemountedupon the Window, the upper sash frame 16 thereof lowered in window frame [-1 to its-fullest extent so that it is positioned alongside thelower sash frame l8. With thesepositions the tops ofboth sash frames are together. so that. the. U -shaped bracket I of the hoisting device. may beinverted and slipped over these ends at the side of the sash frame so that. the legs will extend downwardly along the side framev member of each sash- When the hoisting means is to be used, the arm "5 of each hoisting device. is swung outwardly to the, positionshown inf Figure 2so that the outer end of the armandpulley will be away from the building. To raise or lower a storm sash the snaps l5 on the cords are attached to the hangers l.9 of the storm windowill. If the storm window is on the ground, itcan be raised up to the window by ,pulling on the. cords. If it is already up atthe window,it can be lowered to the ground by means of the cords.

Duringthe installingof the storm window on the hooks 2 I atthe'top of the window'frame and removing it therefrom, it is desirable to have a support for the storm window'so'asto permit easy attaching and detaching of the cords "to A cord l4 passes over I the storm window hangers. This support is provided by the previously mentioned supporting means C which is so constructed as to be readily associated with the window. As best shown in Figure 1, the supporting means comprises two

members

22 and 23, such as strips of wood, which members are pivoted together by a hinge 24. The free end of the member 23 carries a rest 25 having a brace 26 associated therewith. The supporting means is placed in position by merely placing member 22 across the center of the bottom member 2! of the window frame so that the members 23 can hang downwardly alongside the building below the window sill. The supporting means is maintained in position by the two window sashes when in their lowered positions, it being noted that member 22will then be held between the bottom member 2'! of the window frame and the bottom frame members of the window sashes. The member 23 of the supporting means is of such length that when the bottom of the storm window is positioned on the rest 25, the top of the storm window will be just below the arms of the hoisting devices.

With this supporting means it is seen that when the storm window is being hoisted from the ground for installation, the bottom thereof can be positioned on the supporting rest 25 after the storm window has been pulled up to where the top of the storm window is just beneath the arms.

With the storm window in this position it is not necessary for the person installing the storm window to support it by his own strength and, therefore, he will be free to unsnap the cords from the hangers IQ of the storm window. When this is done, each of the arms can be swung back out of the way to the position shown in dashed lines in Figure 2. With the arms out of the way they cannot interfere with the actual hanging of the storm window. To install the storm window theperson need only reach over the top of the two lowered sashes andgrasp the storm window on each side intermediate its ends. He is then in a good position to raise the storm window through a distance approximately half its length and to then place the hangers IS on hooks 2|.

In-removing a storm window the operation is reversed. ated with the window and then the hoisting de- The supporting means is first associvice is mounted on the window sashes with the u per sash in lowered position. The arm A will be placed in the dashed line position. The storm ,window is then unhooked and its bottom posibracket so it can be used with either size. To accomplish this the bracket l is made so that the space betweenlegs 3 and 4 will fit the thicker sash frames. When the bracket is to be used with the thinner sash frames, a block 28 is proyided which is attached to the inside of leg 3, as

'indicated by dashed lines in Figure 2.

From the foregoing description of my hoisting means, it is seen that a storm window can be very easily and quickly installed or removed from an upper story window frame. tall laddersfor hanging or the carrying of the ,storm' window through the house and boosting The use of it throughthe'window are both eliminated by the use of the hoisting means. By using the hoisting means, handling is reduced to a minimum, thus decreasing the possibilities of glass breakage. There is also a considerable saving in labor as it permits the storm window to be easily raised to an upper story window or lowered therefrom. When the storm window is at the upper story window and positioned on the rest of the supporting means C, it is in a good position for proper grasping to place the hangers on the hooks.

In Figure 4 there is shown a hoisting device which can be made from metal. The bracket I is made of a single member formed in the shape of a U with a base portion 2' and legs 3 and 4', the leg .4 having an outwardly extending projection 29. The arm 5 is also made of a single piece of metal bent in the form of a V with'the leg portion 6' pivoted to the bracket I by a pivot pin 9' and the other leg portion 1' acting as the brace with its end adapted to abut the leg 4' of the bracket and to be retained in position by the projection 29. The pulley is mounted on the end of the arm by a bolt 30. The hoisting device is used in the same manner as the one previously described.

Being aware of the possibility of modifications in the particular structure herein described without departing from the fundamental principles of my invention, I do not intend that its scope be limited except as set forth by the appended claims.
