ERNEST E. HEINTZ, F DETROIT, MICHIGAN, ASSIGNOR TO TERNSTET MANUFACTUR- ING' COMPANY, OIE' DETROIT, MICHIGAN, A CORPORATION 0F MICHIGAN.
WINDOW-REGULATOR DRUM.
AApplication led November To all whom #may concern:
Be it known that ERNEST E. HEINTZ, a citizen ot' the United States, residing at Detroit, in the county of Wayne and State of Michigan, has invented certain new and useful Improvements in llVindow-Regulator Drums, of which the following is a specifi. cation. 1
This invention relates to window regulators and has for its object an improved and cheaper upper drum and spring retaining cup construction. In my copending application Serial No. 659,449, Iliave shown a drum which is preferably a die cast drum,
a spring retaining cup which can be successfully used with this Vtype of drum. It is the object of the present invention to provide a 'stamped metal drum which is also provided with a spring retaining cup which has the dual function' ot' housing the spring and also reinforcing the sheet metal drum.
In the drawing.
Fig. l is a side elevation ot' the upper portion of a regulator equipped with my improved drum and spring cup.
Fig. 2 is a section taken on the liuc, 2-2 of Fig. l.
Fig. 3 is a composite view showing `the tour operations which are performed on the metalto form the drum.
Fig. 4 is an inside view ot the drum and the cup showing the spring in place.
5 is a cross section on the line 5 5 of Fig. l, through the completed drum and spring retaining cup.
Fig. 6 is a section taken on the line (3--6 of Fig. 2. i
Fig. 'Z' is a section taken on the vline 7--7 of Fig. 6.
The re later is a cable type of regulator. This is ully described and claimed in my copending application Serial No. 659,44, Where the cable is shown running around the drum a a few times, and also Wound around the driving spool The cable is fastened to both the drum and the spool sothat there is no possible slippage? between the cablel and the drum or spool. The cable is as positive in this respect as the familiar chain type of regulator. c desig nates a directionegiving shcave for causing the cable to run alongside of the spacer barval parallel therewith. al designates a saddle for supporting the sash plate and causing the same to ride on 'the flange e 5, 192s. serial No. 672,792.
of the drum so'as to relieve the cablevof the weight of the sash.Av This is described and claimed in my copending application Serial. No. 672,793. y In order to meet the closely competitiv `market that new exists in wfudow regnlators, and to altord a regulator which is ywithin thercach of the uw priced cars, it is have been considered somewhat of a luriury and not a necessity. In some of the cheaper types ot regulators they have been elimi-A nated to lessen the cost.. However, they are very desirable for good operation of the regulator because they equalize the drivingl effort required to raisethe window and the driving etlort required `to push the Window down.
In my copcnding .application Serial No.
659,449 I have shown and described a die f cast cable drum. A die cast cable drum is a very goed drum for the purpose, but die casting operations are relatively slow and require the use of considerable metal. It is the ohyect of the present `drum and spring' construction to substitute a stamping for the die cast drum. However, the problem is cons1dcrably more than simply specifying a stamped drum in place of a die cast drum. i
A. piece of sheet metal is` punched' out shownipiat f 1n Fig. L3. The second operation is to :former stamp it up into a cup g, as
shown in 3. The third operation is to reduce its diameter as shown at L to form a flangey c at the base of the 'dr-um. The fourth operation is to roll the thread y' on the drum. In order to permit this stamping. and especially the rolling of the thread, it is necessary to use rather light stock.
`This stock is hardly strongenough to do the work assigned to it, hence I find it desirahlc to reinforce the drum. This I 'do without requiring an. additional element by simply telcscoping the spring cup il: in the drum so as to abut directly against the inside of the peripheral Walls of the drum. It is desirable to have the spring cup as a separate article of manufacture so that the assembled spring may he shipped by the manutacinrer of the spring to the regulator man u'acturer. The spring maker either makes these spring cups or buys them and assembles the clo ik-1ike counterbalancing springs m in the cup,
' tion.
. the drum hub. ',The regulator manufacturer hasn reduced end cup telescopioally The regulator manufacturer then assemf bles the parts together invthis manner: The regulator plate is hossed out as at o (Fig. 2). This boss isadapted tor seat the drum. At the center, four lugs p are struck out of the regulator' plate to provide a guard to kprevent the coiled spring from bearing on bushing or hub r Which (y. IIe places the spring within the drum, inserts hub and then spinsover then takes a brass the brass bushing or -the end of the hub, asshown at sin Fig. 5.
This locks the spring cup to thedrum. One end of .the counterbalancing spring is bent over and anchored lin between the struckout lug t of the spring cup and the rim ot the cup, the other end of the spring is lbent over as ati'J and engages at the side of one of the guard lugs or posts at the center of casting the drum.
the drum. Hence, one end 'of the spring is anchored to a stationary post and the other to a. movable post. It Will be seen that Whenthe spring cup is fitted into the drum this very materially reinforces ythe drum, which is made of relatively light gauge stock in order to permit the rolling of the thread. This construction makes avrelatively cheaper drum construction than can behad by lWhat I claim is: v1. In a window regulator, a cable drum comprising a member formed of relatively thin sheet metal folded upon itself at one side to form a iange, and having a continuous thread rolled in its periphery.
"corrugated periphery by modos;
constructed of comparatively light gauge -sheet metal stookhaving a circumferentially reason of'pressure applied thereto, and a reinforcing member closely telescoping within the drum and actin'g as a counterbalancing spring retainer.
4. In va window regulator, asheet' metal, circuiiierentially corrugated cable drum, a cup telescoping into the drum and acting as a reinforcement, and a hub member With a reduced end for riveting the reinforcing'cup to the sheet metal drum.
5. In a Window regulator, a regulator plate provided with a'plurality of struck ont guard posts, a sheet-metal cable drum, a rcinforcing cup secured in the drum and acting as a spring retainer, a hub for the drum, a bearing secured to the center of the regulator plate for rotatably mounting the hub of the drum within the guard posts, and a coiled spring having its outer'end secured to one of the guard posts which hold the same from constricting upon the hub.
(i. In a window regulator, a cable drum of light sheet metal provided with an externally areinfor'cing cup telescoping closely in the' cable drum for reinforcing the periphery thereof.
In testimony whereof he has affixed his signature.
