This invention relatesto a sash-holding de.-

1 vice to be employed with a window sash and" replaced.

r window sash with parts frame in place of the usual cord and weights forcmaintaining the window in a given position. With this device no weight chamber isnecessary in'thewindow frame, hence-a great saving'in space isaccomp'lished -Another advantage gained is the fact that no space is provided for the accumulation of dust to be blown about when a sash cord is The, absence of the weights reduces the weight ofthe'complete window assembly, a feature of great importance particularly for motor vehicles and in "ship building where weight is an important factor. I j

The principal object of the invention is to. provide a device of the character describedwhich will be an improvement overthat dis v closed in my prior Patent'No.,1,553,306, issued September 15, 1925.

The principal feature of. the. invention resides in the provision of apair of members having depressions in one which are engaged: by correspondingly spaced projections inthe other, the said members being mounted respectively on the'window frame and on the sash. One of said members is yieldingly mounted so that the depressions and projec tions engage with sufficient force to overcome the tendency of gravity to lower the window but at the same time permit movement thereof. by hand.

Another feature of the invention resides in the provision of projecting portions on one of said members which are used as guideways for the window sash to prevent rattling and to form a weather stripping.

The full nature of the invention and other objects and features thereof will be fully understood from the accompanying drawings and the following descriptions and'claims In the drawingsFig. 1 is an elevational' view of a portion of a window frame and cut away to show the invention in detail. Fig.2 is a horizontal cross section taken on the line 22 of Fig. 1. Fig. 3 illustrates a modified form of the device shown in similar cross section to Fig. 2. A window frame 10 is here" shown as a window s. of the said member,-

provided in passage 0 the sash and For example, the channel-shaped members.

solid member having no chamber-therein for the-usual window weights and cords. Associated therewith is a window sash 11 having a window pane'12. "The'sash is held-in place by theiusual projecting portion 13; of tlie window frame and the usual waling strip 'Fastened inthe groove between; the portion 13 andithe waling strip 14: of the window frameis arcuate depressions 16 in the web thereof. The member 15'preferably extends the whole height of the window frame 10 and is fast'ened thereto by means of screws 17 l inserted through"counter-punched holes inthe web p The legs of the channel shaped member 15 engage mortices 18 the window sash and act as a guide for said sash to prevent rattling and also act as Weatherstripping to prevent the fair about the window. A metallic 'strip' 19 has fastened thereto a plurality .of cylindrical members 2Q peel--- tioned within cylindrical recesses in'the'win- -dowsa'sh. I Certain of the members 29 are 7 1 v surrounded by helical springs 21 abutting at one end againstthe member 19 and at'the other against the inner end of the aforesai V cylindrical recesses. "The member 19 I carries arcuate projections andproper dimensions to engage the arcuate depressions 16 0f the member 15. The'engagem'ent of' the projections 22 and therecesses 16i's maintained by the springs 21 and the springs are so gra of the'wi'ndowis not sufficient to break the said engagement, but the'man'ual application of a small'additional force willbe sufficient to raise and lower the window. 7 In the construction herein shown the por-- 99 tion ojf'the device carried upon the window sash isshown located adjacent to'the'lower edge of the sash. A' similar construction is preferably positioned near the upper edge of 1 both sides of the sashare similarly equipped. i 1

Several modifications of the structure herein shown are possible without departing from the broader aspectof'the invention.

a channelshaped member 15 having so 1' 22 of the proper spacing duated thatjthe weight we a maybe placed on the window sash and the yieldingly-mounted members may be placed on the window frame. The arcuate depressions and projections may be in the reverse relation to that shown'herein and need not only necessary that the lower portion of each projection and depression be shaped to-engage at the proper angle. The shape of the upper portionof each projection and depression is immaterial except that they should offer a minimum resistance to raisingthe window. If the weather stripping and guide feature is not desired, the channelshaped members 15 may be replaced by a simple plate carrying appropriate projections or depressions.

Fig. 3 illustrates other modifications of the device, wherein the channel-shaped member 15 is replaced by an L-shaped'member 115 engaging a single mortice 118 in the window sash. The member 115 has depressions similar to the depressions 16 in member 15 and is hereinshown'covered with a coating of rubber 123 or other resilient'material for noiseless operation. A roller 124 pivotally mounted in a yoke member 125 en gages the rubber coating 123 and is yieldingly associated with the window sash 11 by means of, spring 121 as disclosed in my prior patent aforesaid. In this construction the roller 124 may be considered as the projecting portion of the yieldingly mounted member in the same manner as portions 22 previously described. V

The invention claimed is:

1. The combination with a window sash member and window frame member, of an element secured to one of said members and having a portion closely engaging a mortice in the other of said members, and a yieldingly-mounted element carried by said lastmentioned member, said elements having corresponding projections and depressions shaped for yielding engagement.

2. The combination with a window sash member and a window frame member, of a channel-shaped element secured to one of said. members and having'portions closely engaging mortices in the other of said members, and a yieldingly-mounted elementcan ried by said last-mentioned member, said elements having corresponding projections and depressions shaped "for yielding'engagement. r

3. The combination with a window sash member and a window frame member, of a metallic element secured to one of said members and having a port-ion closely engaging a mortice in theother of said members, a metallicvstrip associated with the other of said members, elements attachedto said soc- 0nd strip and receivable in recesses in its associated window member, and yielding means interposed between said strip and its associated member, said strip and said metallic element having corresponding depressions and projections for yielding engagement.

The combination with a window sash and a window frame, of a metallic element secured to said window frame and having a portion closelyengaging a mortice in said window sash, metallic strip associated with the said sash, elements attached to said strip and receivable in recesses in the said sash, and yielding means interposed between said strip and said sash, said strip and said .metallic element having corresponding depressions and gagement.

5. The combination with a window sash and a window frame, ofa channel-shaped element secured to said window frame and having portions closely engaging mortices in said sash, a metallic strip associated with said sash, elements attached to said strip and receivable in recesses in the said sash, and yielding means interposed between said strip and said sash, said strip and said channelshaped element having corresponding depressions and projections for yielding engagement.

In witness whereof, I have hereunto aifixed my signature.
