' This invention relates to" window hoists and the like) This"hoislt is particularly intended to be used; forhoisting and dumping material into windowsofbuildings which are under construction.

An {object of this'invention isto provide ehoist' whi'chfcan be quickly andeasily applied to anopeliwindow. r

3 Another obj ect isto provide means whereby the hoist is readilvadjustaible forjiwiih dows ofdifi'erent 'widthsandheig'hts and one which at the same timefissimple and efiicient in its operation! L X These and other objec'ts,'a s will hereinafter appear, are acconi plishedby this invention which is fully described in 'theflfollowing specification and shown in the accompanying drawings in which 1 Figurel isa vertical "section through a window opening showing the hoist'inside elevation; 1 i y Fig. 2is apartial enlarged vertical section on the line2 of Fi .11;' Fig. "3 is (l-partial vertical section on the ZFig. 4: isa partial perspective View ingpart of the main frame; :i'nd'" :3

' *Fig. his a partial enlarged section on the line 5 of Fig. l 1 .7 The embodiment illustrated comprises essentially two frames one of which; lies with in'the window, while the other liesoutside of the window. Thej inner frame consistsof two vertical rods one'ateach side of the window which are adaptedto rest uponthe' floor 11 of a room, and theserods carry clips or thelike 12whereby a cross beam 13 conjsistingpreferably ofe pipe is located.

1 The-outer frame previously referred to conshow} sists of two verticai'l members lwhich are also preferably pipes, and which are adapted to rest upon the outerportion of a window 'sil115, The pipes "14 carry clips 16 which are secured'theretojby U-bolts or the like 17,

'45 and these clips secure a horizontal pipe 18 by .whichth'ey maybe tightened, r Eye-bolts21 hook over the 'tra nsversle rod to theverticulmeinbers 14; e-561mg 51mg ably engigethe vertical members 10 and pass through o eni gs inithellower partof the vertical members 14: andi'have 18 and are adapted to pass between cross braces 22 which, in turn; beain'upon the vertical members 10. These eye bolts are pr de ith llsu s 23 y w ich eyamay as be tightened so as to clamp ithen innerjand outer frames firmly upon the window-opening. The transverse member 18 is prbvided with two spacedfslins 24 which Jere firmly securedinplace thereon together lateral 0 presses 25. by means of electrical welding or the like. Theses slings are" made to eiiteiid some distance through th-elwindow opening and are provided ontheirlowerfedges with parallel int-urned portions 221?, the sziine being k adapted to receive the. lpweriportions of a boom 26 whichpin crosssection is inidein the form of anjinifefled ugasshownin Figy2.

flThe metal legpof thetT-bars 27serveslasa ,v

bracket upon which ihounted. a" movable sheave" frame 29 which carries series "of rollers30and which. are adapted to roll upon v The frame29,has dependingportionsf2i2 through which passes a central pin 31 upon t which is; revolvably firiounted La hoisting sheave 32. The boom26fas a whole, is slidto a hook 35 at the inner end of the boom, this chain being adapted to be secured through a turnbuckle 36 and a hook 37 to the floor joist 38.

A gravity-operated bucket 39 is provided with a bail 40 which is eccentrically mounted on the bucket by means of pivots 41 on two sides. These pivots, as shown in Fig. 1, are placed to the left of the center of the bucket, so that the weight of the bucket alone, or of the bucket and contents, tends always to keep the bucket in the position shown in Fig. 1, in which the stop 42 is in contact with the bail 40. A handle 43 is provided for ease in operating the bucket, as will hereinafter be stated.

The bail 40 is secured to a suitable rope 44 which passes over the sheave 32 and down to a suitable hoisting drum (not shown). The sheave frame 29 has an operating handle 45 pivotallysecured thereto at 46. The outer end of this handle is bent down at47 and overlies a bolt 48 which passes through lugs .24 on the slings 24. This bolt is provided with a wing-nut 49 by which the bolt may be tightened so as to firmly secure the slings 24 in adjusted position on the boom 26.

A bolt 48 striking the bent end 47 of the operating handle 45 serves: as an outer stop for the sheave frame 29. A clip 50 secured to the operatinglever 45 provides aspace into which the bolt 48 falls, as shown in Fig. 3. 4

The operation. of this window hoist or derrick is asfollows: The method of assembling the main frame in the window, as well as the method of adjusting the boom 26 in the-sling 24 and then of anchoring this boom in place, will be readily understood from the foregoing description. Assuming that the parts are inthe position shown in Fig. 1, andthat the bucket 39 which is filled withv mortar or the like has been raised to the position shown in full lines, the operator grasps the extension 47 of the operating lever 45 and lifts the lever so that theclip 50 clearsthe bolt 48. He then draws in on the lever so as to bring it to the position shown in dotted lines in Fig. 1, the sheave 32 then assuming thedotted line position shown in this figure. The operatorthen grasps thehandle 43 on the bucket and tilts the bucket forward so that it dumps throughthe open window onto the floor 11. A suitable receptacle (not shown) is usually provided where mortar'is thus-dumped. The operator then rocks the bucket 39 back and its weight retains it in the normal position as shown in full lines. He then pushes the operating. lever 45 back to the position shown in Fig. 3, .theclip 50 riding. naturally. over the pin 48" and. dropping so asto lock the operating lever thereon.

It will be seen that Ihave provided a very simple and efficient. form of window hoist T which is readily adjustedto accommodate-itself to windows of various size and height.

While I have shown and described but a single embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as covered by the appended claims.

I claim:

1. A window hoist comprising a frame adapted to be secured to a window opening, a boom of inverted U-shape crosssection, a pair of sling members carried by said frame and adapted to lie one on each side of said boom andhaving i'nturned flanges adapted'to engage and support the boom, and a sheave frame movable in said boom.

,2. A window hoist comprising a frame adapted to be secured to a window opening, a boom of inverted U-shape cross section, means carried by said frame for supporting said boom intermediate the ends thereof, said boom being adjustable endwise in said holding means.

3. In a hoisting device, spaced frame members, means adj ustably connecting said frame members to engage opposite side faces of a wall adjacent an opening, a sling pivotally carried'by one of saidframe members, a boom slidably mounted in said sling to extend on opposite sides of sa-idframe members, means adapted to secure said boom against sliding movement" in said sling, means adjustably eonnecting'one endof said boom to the other frame member, a sheave block= movable towardand from the other end'of said boom, and means supported by the boom securing means for moving and securing said sheave block;

r 4. In a hoisting device, spaced frame members adapted to engage opposite side faces of a wall adjacent an opening, a sling pivotally carried by one ofsaid frame members, a boom slidably mounted in said sling, means adapted to secure said boom against sliding movement in said sling, and means adjustably connecting the boom tothe other frame member.

5. In a hoisting device, spaced frame members adapted to engage opposite side faces of a wall adjacent an-opening, a sling carried by one of said frame members,a boom slidably carried by said sling, and means adjustablyconnecting the boom to the other frame member.

6. In a hoisting device, a supporting frame, a sling pivotally carried by said frame, a boomslidably adjustable in said sling, and means adapted to secure said boom inaugular adjustment-about said sling pivot.

7. In a hoisting device, a supporting frame, asling carried bysaid frame, aboom of inverted U-shaped cross section carried by said sling, tracks carried within said boom, a

sheave block movable on said tracks, and

means movable through said boom and connected to said sheave block for advancing, retracting and securing said sheave block.

8. In a hoisting device, a frame, a boom of'inverted U-shaped cross section carried by the frame, and a sheave supporting and'operating device movable within the boom and having an operating handle depending from said boom. r

In testimony whereof, I have hereunto set my hand this 16th day of May, 1928.
