1 194 J75 I Specification of Letters Patent. Patgntqgd Aug, 115, LYQQL Application filed September 4, 1912. Serial No. 718,587.

To all whom it m ay concern Be it known that we, Oscar: OEIIRING, technical manager, and Gnonc Hanna, manufacturer, subjects of the Kings of Prussia and Saxony, respectively, residing at Eisleben', Germany, and Dresden, Saxony, Germany, respectively, have invented certain new and useful Improvements in S'aslrFastenors and Lifts, of which the following is a. specification.

This invention relates to an improvement in sash raising and lowering mechanism, and has for its object to provide an improved mechanism wherein but one handle is em-. ployed for releasingthe sash or window frame for raising or lowering the sash. or pane into the desired position, and subsequently to secure the sash or pane in the adjustr position.

Other objects and advantages of this invention will appear from the following detail disclosure of the present embodiments of the invention, the same being disclosed in the accompanying drawings wherein,-

Figure 1 is an elevation of one form. of the device of this invention,'showing one of the side plates removed to" disclose the inner The lower ends of the links 100 are pivotally l j Fi 2 di l i l ti connected by a cross piece 10. and by means and in section a slightly modified form of of studs 105 carried by the bracket 103 and the device. Fig. 3 shows in ele ti nd i hingedly engaging through the ends of the horizontal section a further modification of links 100, and the ends of the crosspiece the device of this invention an edge view lO-t. By this arrangement the springs 102 of the rotary "element being also disclosed. normally urge the lazy tongs into expanded Fig. 4 is a vertical section of another modi provided upon its outer end with a handle 46 for turning the shaft 62.

Between the plates the shaft 62 has fixed thereon av ratchet disk 64: the teeth of which are rounded or bcveled for a purpose which will hereinafter appear. A toothed segment 66 is mounted to turn upon the shaft and is provided with a slightly elongated slot re ceiving a pin 65 projecting laterally from the ratchet disk 64, the pin and the slot constituting a loose connection between the disk 64 and the segment 66 admitting ofa slight initial .movement or" the disk (Si prior to moving the segment and its parts. The segn'ient 06 is provided with a radially extending arm 45 hinged at its outer end to a bar 42 extending down into the Well 10 and having pivotal connection at $1 with the closed portions of pair of arms of the lazy tongs 39. The lower end of the lazy tongs 39 terminates in a pair of links 100 having upon their lower ends oii'set hooks 101 re- 102. The outer ends ot" the "springs 102 are fixed in the opposite ends of bracket 103 secured in the bottom of the well 10.

position and act as counter-balances for the sash or pane 1 which is secured and supported upon the upper end of the lazy tongs 39 by means of a strip 106.

Between the plates 1 and II is pivoted a pawl 67 yieldingly urged against the teeth of the ratchet disk 64.- and the segment 66 by a spring 68. When the disk and the seg- AA of Fig. 5. Fig. 5 is an elevation of the same. Fig. 6 is a vertical section similar to Fig. bnt showing a slightly modified form thereof. Fig. 7 1s a transverse section taken on the line BB of. Fig. 6. Fig. 8 is a view similar to'Fig. 6 showing a further .nodified form of the clamp releasing means.

Jteferring particularly to Fig. 1 of the drawings the sash or pane l is mounted in a frame which may be in the form of a door or the like, and which is provided with a. well 10 into which the sash or pane 1 may be dropped for opening the window. At one side of the we'll 10, and secured to the main frame. are a pair of spaced apart plates I and ll. in which are mounted a transverse Fig. 1 the beveled or rounded teeth of the disk (S-l are in alinemcnt with the throats oi. the teeth of the segment 66 and support the pawl 67' out of engagement with the teeth of the segment 66. When in this positi on the seigment 66 may be swung in. the direction opposite to that indicated by the arrow in Fig. 1, to expand the lazy tongs 39 and raise the sash: The slot in the segcnds through the plates. The shaft 62 is (35 is moved into the opposite end of the ceiving the inner ends of contracting springs ment 66 is of such length that when the pin n'lent are in the relative positions shown irr'85 slot the beveled teeth of the ratchet disk 64; are moved a distance equal to the Width of a tooth so as to register the same with. the next succeeding: threats of the teeth of the segment 66. By this arrangement the handle ifimay be swung in the direction indicated by the arrow in Fig .1 to first register the teeth of the dish and. the segment and admit of the engagement of the pawl (37 with the teeth ofthe segment to lock the same from movement, and subsequently raise the pawl 67 out of engagement with the teeth and place the same in a position'to be rotated in the direction of the arrow for lowering the sash or pane 1.

Above the weih and in the inner side of the main frame, is disposed a clamping" frame 89 the same being suitably supported whereby the lower end thereof may be swung toward and from the sash or Pane 1 so as to clamp the sash from rattling or re lease the same when it is desired to operate it. This clamping frame 89 is provided with a linger .107 depending therefrom within the well and adjacent to the inner plate 11. The shaft 62 carries upon inner end a clamping arm 69 adapted to be swung up' into vertical position when the operating handle d6 is raised to lower the sash 1. The arm 69 is provided with a rounded projection adapted for engagement between the finger 10? and the plate 11 to force the linger 107 inwardly, more the frame 89 therewith and thus bind. the sash 1 from rattling or from accidental movement during the vibration of the main frame. For facilitating the engagement of the arm (39 beneath the finger 107 the latter is provided "with a beveled lateral edge ?2 which produces the clarnpihg action of the arm (59 when moving the clamping frame against the sash. Thus after the handle 46 has been moved to adjust the sash 1 into the desired lowered position. the arm 69 is 1 brought into position by the handle to clamp the frame 89 against the sash 1 and thus lock the sash in its adjusted position.

In. Fig. 2 a slight'n'iodification of this structure is disclosed wherein the segment upon the disk (i l and which permits of the free movement of the'handle 416 for a considerable distance to lock and unlock the sash 1 by means of the arm 69 prior to enfifl gaging the pawl 67" with the segment 66 6 1 has a smooth periphery with a recess or.

05 when the disk 73 is turned.

which projects the pin or stud carried In Fig. 3 of the drawings a further T110(l1" tied form of the invention is disclosed wherein the handle controls trio raising and lowering" of the window as well. the clamping of the same When it is adjusted As will be noted from Fi the shat upon which the handle 16 is mounted i vided between the plates 1 and l vwith 7 having a stud (35 passing err-new through the disk and extending beyono. the

opposite sides thereof. Loose upon he shaft 62, and aga nst the outer sin. or the disk 73, is a lever connected to la tongs 39 at its outer end and having" upon its inner end a projection 198 in line "ith the outer end of the stud 65. For raising and lowering the window a handle. 46 is moved to turn the shaft 622 and thus rotate the disk 73 to move the outer end of the stud 65 against the projection 108 to swing the lQVC-l. ili in the direction opposite. to that indicated. by the arrow in F 3 to expand the lazy tongs 39 and thus raise the sash 1.

The outer end of the stud 65 is also ada-pt ed to be moved into engagement with the long arm ot the lever 415 to press the same down and collapse the lazy tongs to thus more the sash down into the well.

The means for clamping the sash in position when adjusted comprises a pair of fingers 75 extending downwardly from the opposite ends of the clamping frame 89 and having beveled or rounded edges adapted to receive thereagainst cor 'espondingry formed abutmcnts 71 mounted on the opposite ends of a sliding bolt 109. The bolt 109 is mounted upon the plate 11 and has fixed to its middle portion a slotted plate 110. 110 projects down toward the shaft (Q- and has intermediate its ends a vertical slot 111 adapted to receive the inner end of the stud When the stud (55 enters the slot 111 the stud moves the plate 110 and the bolt 109 from the position shown in full lines in Fig. 3 to the central position shown in dotted lines in the TlllS movement of the bolt 109' against the sash. Further movement of the handle 46 in the direction indicated by the arrow in Fig. moves the plate 11.0.toward The plate the left, disengages aloutments 7 1 from the fingers Z5 and moves the "inner. end of the stud out of the slot 111.

For the purpose of retaining the plate 1.10 in proper position to register the slot 111. with the stud 65 when the latter has moved. away from the plate in the operation of the lever 15, the plate 110 is pgovided at its 0pposite ends with curved slots 1 12 conforming to the curvature of the disk 73 and adapted to be moved into position concentric with the disk 73 by the stud (35 i iter the latter leaves the plate. A pair of pins 113 project inwardly from the disk '13 and engage in the curved slots 112 when the stud 65 leaves the slot 111, the pins 113 being employed for'thh purpose of holding the plate 110 from accidental movement, by vibration or the like, until the stud 65 is again engaged in the slot 111. From Fig. 3 it will be noted that one of the pins 113 is entering one of the curvedslots 112 while the stud 65 is about to leave the slot 111 in order to ac- "1 tuate the lever 15.

Referring now to the modification disclosed in Fig. 4:, it will he noted that the main frame is provided in one side of the well with a sprocket wheel 81 fixed upon a hub 90 which is journaled for rotation in the main frame and which is provided at its outer end with a pair of cars pivotally supporting between them the handle 46. The inner end of the handle is formed into a cam 91 having at its center a notch for the purpose which will hereinafter appear. The hub 90 is hollow'and contains a rod 87 adapted for longitudinal sliding movement in the hub 90, and a helical. spring 88 surrounds the rod 8'7 abutting at one end against a detachable disk 1145 closing the innor end of the hub. The opposite end of the spring 88 bears against a stop 115 fixed upon the rod 87 near the outer end of the hub. The rod 87 projects beyond the disk 115 and through the hub. into the space hetween the ears on the hub and is adapt-ed to bear against the cam 91 and to move into the notch 92 when the handle is swung up into horizontal position. The inner end of the rod 87 is pivoted to the fork arm 85, the

arms of which are pivoted as at 86 to the main frame and are adapted to swiag about by pivots when the rod 87 is forced inwardly by the cam 91. The lower end. of the fork arm projectsbelow the hub and is turned in to provide a friction stop 84:. The stop 81 in Fig. 4 is shown as an inturned finger while in Fig. 5 the stop is shown as a roller 84. The sprocket wheel 81 is provided with an annular groove for the reception of the friction stop 81 which latter is yieldingly held in the groove by the spring 88 and the rod 87. The sash or pane 1 is connected by a rod 82 to a chain passing over the sprocket wheel 81 and down into the well.

hen the sprocket wheel turned. by turning the handle 46, the chain 80 is moved over the sprocket wheel and caused to raise or lower the sash as is desired. lhe sash is held in clamped iosition by the clamping frame 89 which, as shown in Fig. 1, normally bears against the sash 1 to hold it firmly in place. The upper ends of the arms of the fork lever- 85 above the pivots 86 lie in the path of a flange or finger 116 projecting down from the bottom of the clamp frame 89. 'With this construction it is readily seen that when the handle 46 is raised into horizontal position the cam 91 forces the rod 87 inwardly against the ten 0 sion of the spring 88 to rock the lever 85 about its pivotal supports 86 to not only Withdraw the friction stop 84; from the sprocket wheel 81 and thus free the sprocket, but also for bringing the upper ends of the fork lever 85 into contact with the flange or linger 118, and to move the same outward ly to thus carry the clamping frame 89 therewith and release the sash 1.

As the sprocket wheel 81, and the sash 1 b have now been released the handle 46 may be turned to rotate the hub 90 and sprocket wheel 81, and to thus operate the chain to raise or lower the saslpl as desired. As soon as the proper adjustment of-thesash is had the handle 16 is again swung down, or to one side, to release the rod (57 and admit the spring 88, drawing outwardly the lower end of the forked lever 85 to release the clamping" frame 89 and frictionally hold the sprocket wheel 81 from turning". It is thus seen that by the operation of a single handle the raising and lowering means for the window is controlled, and also that the means for clamping the window when adjusted is controlled. '1

In Figs. 6 and 7 or' the drawings a slightly diilerent term of operating mechanism is shown wherein the huh 90 carries a sprocket wheel 81 to effect the raising and lowering of the sash as in the construction shown in Fig. The sprocket wheel 81 is provided upon its outer side with a cam groove 83 in which rides a roller 117. The roller 117 is journaledin a stud 118 slidabie in-"a guide way 93 fixed to the main frame. The stud 118 is provided, as best shown in Fig. 7, with a pair of oppositely extending fingers 98 engaging the lower ends of a forked arm 99 projecting downwardly from the clamping frame 89. A spring 95 is mounted in the casing 93 and hears at its outer end against the stud 118 to normally and yieldingly urge the studoutwardly toward the sprocket wheel. 81 As the roller 117 travels in the cam groove 83 it reeiprooates with the stud 118 in the casing 93. hen the stud 118 is retracted in the casing 93 the fingers 98 of the stud engage the lower ends of the arm Q9, carrying the arm 99 for- Wardly and moving the clamping frame 89 from the sash 1.

In Fig. 8 of the drawing the clamping frame 89 is provided with a depending arm 99" carrying in its lower end a horirontal roller 11? hearing against the sprocket wheel 81 in the same manner as disclosed in Fig. 6. In this latter case thespring and retracting stud are omitted and the roller is carried directly upon the clamping frame and the usual means for urging the clamping frame against the sash 1. is utilized for holding the roller 117 against the sprocket wheel.
