G. A. CARLSON CHAIN AND WHEEL FOR SASH REGULATING DEVICES Filed April 22. 1925 Patented May 4, 1926.
UNITED STATES PATENT .oF-F cE.
GUSTAVE A. CARLSON, ornnrnorr, MICHIGAN.
CHAIN AND wHnELroR SASI-I-RE'GULATING DEVICES.
Application filed April 22, 1925. Serial No. 25,005.
for Sash-Regulating Devices, of which the following is a specification, reference being had therein to the accompanying drawings.
In my Patent No. 1,537,004, granted May 5, 1925, there is disclosed a sash regulating device of that type adapted to be used in the wall or door of a vehicle body for raising and lowering the sash or other closure relative to a window or door frame opening, and the device is of that type including a casing, a chain movable in the casing and adapted for shifting a sash or other closure, and a wheel for moving said chain, the wheel being directly or indirectly driven from a crank operated arbor.
This invention has special reference to the chain and wheel drive of the sash regulating device and my invent-ion aims to provide a chain and wheel that will be exceedingly narrow so that it may be used in a small space. Ordinarily a sash well or compartment of an automobile is not very wide, consequently there is a limited space for sash adjusting mechanism. It is desirable that the mechanism be as compact and narrow as possible so that it may be easily mounted in a sash well. and chain is very wide compared to my relatively thin chain-and Wheel, and I obtain just as positive a drive as may be attained by an ordinary sprocket wheel and chain.
My invention further aims to provide as a new article of manufacture, a wheel body out and stamped from sheet metal to provide peripheral teeth with some of the teeth offset relative to the wheel body. The chain is composed of artioulatedsingle links of the same material as the wheel body and the chain may be trained on the wheel, in driving relation thereto, with the greatest width of the driving device corresponding to two plies of material, that of the wheel and that of the chain link. This is in contradistinction to wheels and chains made from eastings or drop forgings and it is obvious that my chain and wheel can be produced at less cost with a saving in material and consequently less weight.
My invention will be hereinafter specifi sally described and then claimed, and refer- An ordinary. sprocket wheel wherein p Figure 1 s a front elevation of the chain and wheel drlve' 1n connection wlth the sash regulating device, the cover of the casing being removed;
device showing parts thereof in elevation Fig. 3 is a front elevation of a frame having a sash adjustable therein by a regulating device in accordance with this invention;
Fig; 4 is a perspective View of the detached wheel;
Fig. 5 is a front elevation of. a portion of the chain and wheel;
Fig. 6 is an edge view of the same, and
Fig. 7 is a perspective view of a portion of the chain.
In Fig. 3 there is shown a frame 1 having a sash 2 slidable therein, and inthe sash well 3 is a lock board or transverse member 4 adapted to support the device forv adjusting the sash 2. I V V p I The sash regulating device includes an oblong casing-5 having a detachable cover 6. Slidable in the casing 5 is a chain composed of articulated links 7 with the lowermost link of the chain provided with an angular extension 8- for engagement with a rail 9 on the lower end of the sash 2. The chain links Fig. 2 is a vertical sectional view" of the ence will now be had to the drawing, A
7 are out and stamped from rigid sheet metal I one end thereof provided with a crank 14.
'Loosely mounted on the arbor 13 is the pressed out hub portion 15 of a wheel 16 and disposed about the arbor -13,at the side of the wheel 16, is a clutchpreferably in the form of an irreversible gearing generally designated 17 said clutch being actuated by the arbor 13 to impart rotation to the wheel 16 for sash adjusting purposes. The clutch or irreversible gearing is adapted to preclude any driving of the arbor 13- by the wheel 16, and the details of oneform of irreversible gearing have been shown in my patent above referred to. The form of clutch'or lrreversible gearing herein shown includes a siationary pressed out clutch member 18.;
an inner clutch member 19, an eccentric 20 on the arbor 13, and a slotted plate 21 articulating the Wheel 16 and the clutch member 19 and on the wheel 16 engaging in the slots of the plate 21. Such parts afiord gyratory means of establishing a driving relation between the inner clutch member 19 and the wheel 16, but since this particular application is directed to the chain and wheel drive, it is thought unnecessary to describe at length the operation of the clutch which establishes a driving relation from the arbor 13 to the wheel 16.
Considering the wheel 16, as shown in Fig. l, itis cut or stamped from rigid sheet metal, for instance that from which links 7 are made. Of course, other metal could be used and if so it is preferable to have the metal of the Wheel the same gauge as the metal of the chain links so that when the chain is trained about the wheel, as will hereinafter appear, there will be a comparatively thin driving device.
In producing the wheel 16 it is formed with peripheral teeth 23 and 24 with the teeth 23 coextensive of the body of the wheel so that both sides of the teeth will be in the same planes as the sides of the wheel body. The teeth 23 alternate with the teeth 24 and the latter are offset from one side of the wheel to form straight shoulders 25, the teeth at being offset adistance approximating the thickness of the metal wheel body,
thus providing shoulders that are comparativel narrow and only of sufficient width to al ow the link 7 to obtain somewhat of a purchase on the shoulders. In forming these straight shoulders a hexagonal, octagonal or other geometrical shape is imparted to the wheel and the teeth 23 and 24 are preferably greater in depth than the width of the link 7 so that the sides of the link 7 may readily coincide with the sides of the teeth.
In arranging the chain links on the wheel alternate links are adapted to engage the shoulders 25 and by reference to Figs. 5 and 6 it will be noted that the pivoted ends of the links are positioned in the notches or spaces between the ends of the teeth 23 and 24 with the rounded edges 10 of the links engaging the end walls 26 of the teeth 23 and 24, thereby establishing a driving relation between the chain and wheel, irrespective of the engagement between the shoulders 25 and the longitudinal edges of the links 7 In practice, the shoulders 25 may constitute supporting means for the chain while the end engagement of the links and teeth con stitute the driving relation. Then the links engage the shoulders 25 of the teeth 24, the links are ina planewith the body of the wheel and consequently there is a two-ply arrangement about the greater part of the wheel, as shown in Fig. 1. As brought out in Figs. 2 and 6 the chain and wheel drive is very narrow and it is in consequence of this relatively thin structure that the sash regulating mechanism does not occupy large space in the sash well. With the casing and its cover made of sheet metal the entire structure is not very thick and as pointed out in the beginning this is a desirable feature in connection with any sash regulating device.
The wheel and chain constitute new articles of manufacture and I believe I am the first to adopt a pressed sheet metal chain and drive for this particular art.
\Vhat I claim is 1. In a sash regulating device wherein a sash is adapted to be raised by a chain trained over a wheel; a chain and wheel drive for such device, the wheel being coinparatively Hat and pressed from sheet metal to provide offset teeth, and the chain being composed of articulated fiat links adapted to engage on alternate sides of the offset wheel teeth and have a driving relation established by ends of said links engaging end walls of said wheel teeth.
2. A chain and wheel drive, as called for in claim 1, wherein said wheel has a plurality of straight teeth in the same plane as one side of said wheel, and a plurality of teeth offset from the opposite side of said wheel, the offset teeth alternating with the straight teeth and providing a chain channel about said wheel.
3. In a sash regulating device wherein a sash is adapted to be raised by a chain trained over a wheel; a chain and wheel drive for such device, the wheel being comparatively flat and formed with teeth, some of said teeth being in the same plane as the body of the wheel, and other teeth offset from the body of the wheel and alternating with the first mentioned teeth, the offset teeth affording shoulders, and chain links disposed so that alternate links engage said wheel shoulders andpositions all of said chain links for end engagement with the ends of said wheel teeth.
4:. In a sash regulating device wherein a sash is adapted to be raised by a chain trained over a wheel; a chain and wheel drive for such device, the wheel being comparatively flat and cut and stamped from sheet metal to form a thin wheel body and teeth, some of said teeth being offset from said body a distance approximating the thickness of the sheet metal body, and chain links formed from similar wheel metal and operatively engaging said wheel so that the combined thickness of the chain and wheel drive approximates two plies of sheet metal.
In testimony whereof I affix my signature.
