1 Claim.
This invention relates to new and useful improvements in operating means for closures, such as windows, and more particularly to mechanism whereby windows or other closures can be operated remotely.
Another important object of the invention is to provide a mechanism of the character stated which is positive acting and not susceptible to the ready development of defects.
Other objects and advantages of the invention will become apparent to the reader of the following description.
In the drawings- 1 Figure 1 represents an elevational View of the swingable sash assembly showing the present invention associated therewith diagrammatically.
Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.
Figure 3 is a vertical sectional view through the fluid'reservoir and main cylinders.
Figure 4 is a fragmentary detailed sectional view of the latch means.
Figure 5 is a side elevational view of the latch element.
Figure 6 is a vertical section on the line 6-6 of Figure 3.
Figure '7 is a sectional view through the control valve.
Figure 8 is a vertical sectional view through a slightly modified form of operator.
Figure 9 is a top plan view of the cylinder assembly shown in Figure 8.
Figure 10 is a section on the line ll0 of Figure 8.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numerals 5, denote a pair of windows to be operated. by the improved mechanism generally referred to by numeral 6.
This mechanism which forms the present invention comprises a base 1 on which is mounted an electric motor a driving a compressor 9, which is connected by a pipe In to the pressure storage tank ll. Numeral l2 denotes a pipe having a valve l3 therein extending from the storage tank H to a fluid reservoir M which may be mounted upon the main cylinder construction which is denoted by numeral I5 and which is divided at its intermediate portion as at l6 by a partition. This divides the main cylinder construction into a.
2| to a link 22, the link 22, in turn, being connected as at 23 to an arm 24, which, in turn, connects to another link 25 as at 26, this latter link being directly connected as at 21 by suitable pivot means to the corresponding window section 5. In each of the cylinders l1, I8, is a compression spring 28 interposed between the corresponding piston l9 and the remote end of said cylinder,
thus holding the pistons 19 in a position adjacent the partition [6.
Ports 29, 29 serve to communicate the interior of the fluid reservoir l4 with the cylinders l1, 18.
A suitable filler closure 30 is provided for the.
Detent means for the window sections 5 is shown in Figures 4 and 5 and comprises a block 38 for each of the window sections having a cylinder bore 39 therein receiving a plunger 40. This plunger 48 has a depending neck 4| pro vided with a beveled head 42 at its lower end adapted to seat in selected depressions 43 of the corresponding bar 44, which is slidable through a horizontal bore 45 in the block 38. This block 1 38 may be detachably secured as at 46 to the sill 41 of the window.
The-top of the block 38 is provided with a cover plate 48 secured in place by screws 49 and through this projects a rod 50 from the piston 40. The rod 50 has a head 5| at its upper end between which and the cover plate 48 a coiled compression spring 52 is interposed. Obviously, by operating the head 5!, the head 42 can be disengaged from the undercut portion 53 of the bar 44 so that adjustment of the window can be made.
A slightly modified form of the invention is shown in Figure 8. This view shows a modification of the operator intended for operating vertically slidable sashes 5a. The operator generally referred to by numeral 55 comprises a pair of cylinders 56, 51 preferably joined together as shown in Figure 10. The cylinder 51 contains a volume of fluid 58' while the cylinder 5i has a piston 59 therein urged downwardly by a compression spring 60. Disposed in the cylinder 56 and interposed between the piston 59 and the upper end of the cylinder 56 is the spring 60 which serves to urge the piston 59 downwardly andto maintain the window sash 5a closed due to the fact that a rod 6| which extends upwardly from the piston 59 and through the upper end of the cylinder 56 connects to the window sash.
From a suitable compressed air source, a pipe 52 extends and connects to the upper portion of the cylinder 51 for placing thefluid 58 under pressure when 'desired A port 63 is provided at the lower portion of the cylinder 51 for communicating the cylinder 51 with the cylinder 56.
While the foregoing specification sets forthznf the invention in specific terms, it is to be understood that numerous changes in the shape,"size and materials may be resorted to without departing from the spirit and scope of the invenv v tion as. claimed hereinafter.
between the reservoir and the cylinder having ,anuopening therethrough for establishing said 15 zbyway of said filler neck when the closure of communication, said connection being accessible said filler neck has been removed.
