COMBINATION I-IOIS'IER AND CARRIER.

Z 0 all whom it may concern.

Be it known that I, NELSON P. LUND, a citizen of the United States, residing at l-Ioulton, in the county of Aroostook and State of Maine, have invented a new and useful Combination I-Ioister and Carrier, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for elevating and for moving horizontally, pianos, safes, and other heavy objects which are often raised and moved laterally through the window frame of a building.

One object of the present invention is to provide novel means whereby the supportingframe may be mounted upon the sill of a window, and be held in place in abutment with the ceiling and the floor of the build: ing upon which the device is employed.

Another object of the invention is to provide a sling of novel form, and to provide novel means for mounting the sling for sliding movement upon the supporting structure.

It is within the scope of the invention to provide a device of the type above described which may readily be knocked down and be disposed in small compass when not in use.

The invention aims to improve generally and to enhance the utility of devices of thattype to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

wall including a window frame 2, the sill whereof is denoted by the numeral 3.

The ceiling is indicated at 1 and the floor is designated by the reference character 5.

In carrying out the invention there is provlded a support, denoted in Fig. 1 generally by the reference character 6. The support 6 is a composite structure and includes tracks 7 to which the upper ends of depending, arched braces 8 are secured as indicated at 9. The tracks 7 and the braces 8 may be fashioned from flat strips of metal, and, if desired, the braces 8 may be twisted in their lower portions, as indicated at 10, to form supporting bases 11, the twist indicated at 10 serving to strengthen the braces and serving to ofl'set any weakening caused by the horizontal disposition of the bases 11, whereby the bases 11 are adapted to receive arched yokes 12 which are secured thereto. Into the inner end of each yoke 12 is threaded a screw 14 provided at one end with a crank 15 and at the opposite end provided with a head 16. The yokes 12 are adapted to be straddled upon the window sill 3 and when the screws 14 are rotated through the medium of the cranks 15, the window sill 3 will be bound between the heads 16 of the screws and the opposite arms of the yokes 12. Thus, the support 6 is held to the window sill 3.

Secured to the rear or inner end of the support 6 is a vertically disposed longitudinally extensible frame, denoted generally in Fig. 1 by the reference character 17. The frame 17 is a composite structure and includes main bars 18, through which the rear or inner ends of the tracks 7 extend, as shown at 19, the tracks being detachably assembled with the main bars 18 through the medium of double pointed keys 20, one of which is shown in detail in Fig. 5, the keys 20 extending across the main bars 18 and the ends of the keys being mounted in the tracks 7 Upper extensions 21 are vertically adjustable upon the upper end of the main bars 18, the upper extensions being held in place by means of clamps 22. The clamps 22,-and other clamps to be referred to hereinafter, may be of any desired form. One appropriate and useful kind of clamp is shown in Fig. 6 and-will be described in detail, the clamps mentioned hereinafter being designated by a single reference character only. Each clamp, then, may, if desired, comprise a U-bolt 23, shown in Fig. 6 as inclosing partially the bar 18 and the exten sion 21, the ends of the U-bolt 23 passing through a clamp plate 24 held in place by nuts The longitudinally extensible frame 17 further includes lower extensions 26 which are vertically adjustable upon the lower ends of the main bars 18, the lower extensions being held in place by means of clamps 27.

In order to produce relative movement between the main bars 18 and the lower extensions 26, levers 28 may be fulcrumed as indicated at 29 in the extensions 26, the inner ends of the levers 28 being loosely received in recesses 30 formed in the main bars 18. This detail will probably be understood best when Fig. 2 is examined. The longitudinally extensible frame 17 further includes a top plate 31 disposed upon the upper ends of the extensions 21, and a base 32 upon which the lower ends of the extensions 26 rest. The'top plate 31 and the base 32 may be detachably held upon the members wherewith they are assembled, by means of dowel pins 33, shown mostclearly in Fig. 1.

Carriages 34 are mounted to slide horizontally along the tracks 7 one carriage being shown in detail in Fig. 4. Each carriage carries adjacent its upper end, a wheel 35 adapted to roll along the track 7 and the carriage supports a sheave 36. Pulley blocks 7 37 are provided and through the pulley blocks27. and over the sheaves 36 falls 38 are trained, each fall at one end being se cured to one of the carriages 34.

Supported by the pulley blocks 37 is a sling, denoted generally in Fig. lby the reference character 39. The sling 39 comprises rigid side bars 40 provided interme diate their ends with eyes 41 in which the lower ends of the pulley blocks 37 are pivoted. Fixed to and depending from the side bars 40 are supporting members 42 taking the form of straps, the ends of the straps being united by buckles 43 or in any other suitable manner. Secured to the supporting straps 42 adjacent their upper ends is a horizontally disposed tie strap 44, the ends of which may be connected by a buckle 45, although the form of the tie strap 44 may be varied, without jeopardizing the utility of the invention.

The invention further includes an arched brace 46, comprising a pair of overlapped members united by clamps 47. The lower ends of the brace forming members, indicated at 48 may be enlarged and forked so as to fit over the upper edges of the tracks 7 adjacent the outer ends thereof.

In practical operation, the yokes 12 are mounted on the Window sill 3 and are clamped thereon by the screws 14, the support 6 th-usbeing connected with the sill. The extensible frame 17 is elongated until it represents approxnnately,the distance between the ceiling 4 and the floor 5, this operation being carried out by loosening and adjusting the

clamps

22 and 27 so that the extensions 2126 may be moved vertically. Then, by manipulating the lovers 28, the frame 17 may be given a final elongation, so that the top plate 31 is pressed against the ceiling 4, the base 32 being pressed against the floor 5. Then, the clamps 27 are tightened up, and the parts will appear as shown in Fig. 1. The piano or other object which is to be raised is mounted in the straps 42, the tie strap 44 being engaged around the ends of the piano or other object, to prevent the same from moving horizontally. The falls 38 are drawn upon to elevate the object to the desired height, whereupon the same may be carried inwardly through the window frame 2, the carriages 34 riding along the tracks When, the suspended object is located outside of the window frame, there is a downward pressure upon the sill 3 and an upward pressure against the ceiling 4. lVhen the object is moved to a position inside the wall 1, the downward pressure upon the sill 3 continues, a minor portion of the weight being supported by the base 32 which is in contact with the floor 5. The top plate 31 and the base 32 serve to hold the main bars 18 of the frame 17 against lateral spreading, and also prevent the upper and lower ends of the frame 17 from marring the ceiling v4 and the floor 5 respectively. The brace 46 serves to prevent the outer ends of the tracks 7 from spreading apart, as will be understood readily.

When the occasion for the use of the structure has passed, the top plate 31 and the base 32 may be removed from the ends of the frame 17, and the frame 17 may be collapsed, it being possible to separate the frame 17 from the tracks 7 by removing the keys 20. The brace 46 may be lifted off the tracks 7 and the sling 39 may also be detached from the tracks. Thus, when the structure is not in use, the same may be disposed in small compass.

Having thus described the invention, what is claimed is 1. In a device for hoisting articles through a window, a support including a track and sill engaging means located below the track and between the forward and rear ends of the track; a carriage mounted to move along the track; hoisting means supported by the carriage; and a frame attached to the rear end of the support, the frame including relatively movable ceiling engaging and floor engaging parts; and means for holding said parts in adjusted positions.
