Dec. 6, Q w R ANTIRATTLI-NG DEVICE Filed June 29. 1951 28 IINVENTOR Owl. Mien! Fatented Dec. 6, 1932 UNITED STATES CARL WIRTH, OF ROCltIESTER, NEW YORK ANTIRAITLING DEVICE- Application filed June 29,

This invention relates to anti-rattling devices adapted for use incombination with windows, screens or any other members which are loosely mounted and have a tendency to rattle in their mounting and the object of this device is to provide a device of this character which is easily attached and operated to take up the undesired motion of the members which cause the rattling.

Another object of this invention is to construct the parts of the device so that they may be made from sheet metal at a minimum costand easily assembled without the use of any hand tools. n

Other objects and attendant advantages will become more readily apparent from the detailed description of the device which follows, reference being had to the accompanying drawing in which Figure 1 1s a vertical sectional view of a portion of two windows with the anti-rattling device mounted on one of the windows to keep them from rattling.

The anti-rattling device, forming the subject matter of my present invention, is, ex-

ceptfor the contact .or cushioning member and the spring member, entirely made .up of with the eyelets 7 and 8 of the 'housingto 2 guide the bolt 'in a straight linemovement 1931; Serial No. 547, 30.

sheet metal parts blanked out and formed inv a punch press practically; ready to be as V sembled. As illustrated. in the several figures the anti matting devicecomprises a housing 1 which is open at the bottom and one end, 55 while the other end thereof is-closedby the curved back 2 which has the cam slot 3 provided therein. The link 4, with which the ,deviceis operated, is adapted to'travel-back and forth in the slot 3 as will hereinafter be 60 described.

Projecting from either side of the bottom of the housing 1 are the

horizontal flanges

5 and 6 which havethe eyelets 7 and 8 struck out'therefrom for apurpose that will pres- 5 ently appear. I The housing 1 is mounted on the base plate 9 which has the outline'of the bottom of the housing and. is provided with a pair of holes 10 and 11 which register have them project thereinto and be expanded therein so as to firmly fasten and lock the base plate to the housing and close the bottom thereof. V

Mountedtoslide in and out of the open end' of the housing 1 is thebolt 12. This bolt has 7 1 the pocket 1.3 formed in the front end in which the rubber contact pad 14 is held in place; For this'purposesmall lugs 15 are struck in on the sides, of thebolt 12 to project 3 into the side of the: rubber pads and keep themfromrsliding out of the pocket after being placed therein. A rounded knob 16, formed by the outer end of the rubber pad, projects from the end, of the pocket 13 and provides the contact surface for the end of the bolt. The bolt has a pair of vertical

parallel guide flanges

17 and 18 extending rearwardly of the pocket 13 which serve to in the housing 1. The metal portion of the bolt 12 is formed up of a single metal blank in such a manner that theends of the blank portion,which form the bottom of the pocket 13, abut and are locked together by theen- 5 gagement of the lug 19 formed'on onenendof the blank into the notch 20*formed in (the other end of the blank as illustrated inFigures band 10., The end of the pocket 13in the bolt 12 is formed by anegrtension 21 of the i .top of the pocket which is bent down at right anglesthereto. Projecting rearwardly from the pocket 13 intermediate of the

guide flanges

17 and 18 and parallel thereto is the spring supporting member 22. This member is acontinuation of the blank portion forming the back 21 of the'pocket 13 which is reduced in widthto have the expansion spring 23 telescope thereover.

The outer end of the spring supporting member 22 projects thru the hole'24 provided in the lug 25 and is struck up from the base plate 9 at right angles thereto. The

expansion spring 23, which surrounds-the supporting member, is located between the "lug 24; and theback of the pocket 13 and the location of the lug with relation to the back of the pocket is such that therspring is held under tensionbetween these two parts when thebolt is in its outer or operativeposition illustrated in Figures 1, 2- and 3.

. To move or withdraw the bolt from the yielding operative position to the non-yielding' inoperative positlon, illustrated in Figares 4" and 10, the link 4 is provided. ,T'hi's link is bifurcated at one end and the outer ends ofthe' bifurcation have the laterally projecting

lugs

27 and 28 provided thereon which engage into the

notches

29 and 30 formed in the bottom of'theguideflangesfl 'and18. The intermediate portion of the link,

which is of narrow width,projects thru the camjslot 3 in the curvedback of the housing 1. On the outside of the housing the link 5 is enlarged to form a handle thereon which overh'angs'the cam slot on each side'thereof. In the operative position the expansion of the spring 23 forces the'bolt 12'an'cl with it 7 y the link 4 to the left until a further movement of the link to the left is' arrested jby the engagement of the overhanging portion of .the handle thereofwith theleft hand end of the curved cam slot 8. This position is illustrated inFigures l'to 3' and in this position the pressure of the spring 23, transmitted to the bolt 12, is applied to the member which is. to be held from rattling. In the mounting of the device it is desirable that the bolt will make contact with the'member which is :to be held'from moving'and rattling before it has reached its extreme outer position so 'that'the bolt will beforcedagainst this memher by a tension of the spring which'will keep the member from rattling.

In the caseof windows, this lateral force will not prevent the windows from sliding up 'surfaceof the' window frame without marring the finish ofit.

ordown while making contact with the bolt because the rubber contact members at the end of the bolt will give due to the spring tension inba'ckof it and'also readily slide over the die" of thefoperatin'g link 4 is forced to'the right so that the overhanging portion thereof f To release the'anti-rattling device the ham slides over the curved back of the housing and draws the link and with it the bolt 12 to the right against the pressure of thespring23.

At the end of the slot in the back of the housingthelink is practically in line with the 1 spring, while its overhanging handle portion is located on a practically straightsurface on the outside of the back of the housing. In this position the link is automatically held against a return movement so that the bolt will remain in, the inoperative position until the handle of expansion of the spring can draw the link back toits starting-position over the curved back ofthe housing.

' Of coursethe anti-rattling device shown and described mayfbechanged in various ways, and var atlons'may be requlredunder certam condltio-ns, therefore, -Wl11l6S01116 of theconstructional details are deemed'preferable and I have shown and described these in detail, it is to be understood that I do not limit myself to such precise construction but-com.
