1 Claim.

This invention relates to building structures, and in particular to means and methods for securing cups in window sash guides, such cups being used, for example, to accommodate fasteners employed in securing the sash guide to the window frame.

One object of this invention is to provide a simple yet eiective means and method for securing a cup in an aperture in a sash guide, this being inexpensive as well as adapted to mass production methods.

Another object is to provide a sash guide having a cup secured in an aperture thereof by forming projections in the walls of the cup immediately behind the rim of the aperture, thereby anchoring the cup firmly to the sash guide.

Another object is to provide an improved means and method of securing a cup in an aperture in a sash guide, wherein the cup is provided with a flange engaging the rim of the aperture and is also provided either with a projection or a ridge on the opposite side thereof from the flange so as to anchor the cup relatively to the rim of the aperture.

Another object is to provide an improved means and method of securing a flanged cup in an aperture in a sash guide, wherein the edge of the aperture is provided with an inwardlyextending ange which tightly grips the side Y Walls of the cup with a press fit.

Another object is to provide an improved means and method of securing a cup in an aperture in a sash guide, wherein the edge of the cup and the edge of the aperture are interlocked and upset so that they are firmly anchored to one another.

Referring to the drawings in detail, Figures 1 to 3 inclusive show a sash guide and cup structure, generally designated Ill, according to a preferred form of the invention, as consisting generally of a sash guide II having a cup I2 secured in an aperture I3 therein. The sash guide l I is employed in windows having a sliding sash, and is secured to the window frame I 4 by fasteners I5 received in the cups I2, only one of which is shown. The sash guide II is roughly in the form of a channel member having a central groove I6 for slidably receiving the window sash, the groove IB being provided with side walls I1 and a bottom wall '8, the latter, in turn, being provided with recesses or countersunk portions I9 surrounding the apertures I3 (Figure 3). The countersinks or recesses I9 are provided for the purpose of receiving the edge flange 20 of the cup I2 so that the fange 2E) will be ush with the bottom wall I8 of the sash guide groove I6.

The cup I2 is of approximately cylindrical shape, and is provided with side walls 2| and a bottom wall 22, the latter having a hole 23 for the passage of the shank of the fastener I5. The cups I2 are preferably stamped out of sheet metal by means of dies, but may be formed in any other manner.

The sash guide II on opposite sides of the guide groove I 5 is provided with front walls 23 and side walls 24. The latter terminate in bent portions 25 which engage the adjacent surface 26 of the window frame I4. The fasteners I5 thus hold the portions 25 against the surface 26 (Figure 3). The cups I2 serve to hold the heads of the fasteners I5 below the level of the guide groove I6 so as to avoid any possibility of interference with the sliding of the sash in the sash guide II.

In order to secure the cup I2 in the aperture I3 of the sash guide Il, the cup I2, after its insertion in the aperture I3, is provided with protuberances or projections 21 (Figures 3, 4 and 5) which are formed by forcing the material of the side walls 2I outward behind or beneath the bottom wall IB of the guide groove I6. As the sash guide I I and cups I2 are ordinarily made of metal this means and method of securing the two together is simplel and effective'.

In order to secure the cup I2 within the aperture I3 of the sash guide III (Figure 8) the' assembly of the cup I2 and sash guide Il is inverted and placed in a special formingxture or machine, generally designatedS()v (Figures 8 and 9) with the bottom walls I8I of the guideY groove I6 resting upon the upper surface or anvil 3| of the machine 30. The latter is provided with a base 32 having a recess 33 therein closed by' a cover plate 34 which carries the anvil surface 3l'. The cover plate 34 is also provided with an aperture 35 of slightly smaller diameter than the diameter of the ange 2B,- so as to support the latter in the positions'hown iri Figures 8 and 9.

neeiprccatlymounted in tneoress 33 is apair ofV oppositely-facing [.-shaped plungers' 36, the horizontal portions 3'1 of which are urgedI toward oiieanother Lby ooil springs 36 abutting the end walls of the recess 33'. A stop 4I) mounted in a slot 4I midway between the end walls 39 prevents the vertical portions 42 of the plunger's 36 from touching one another` and leaves a gap 43 between them The gap 43 iiares outward at its top (Figure 8) dueto the fact that the inner edges of the top portions 421L are bevelledoff as at 44 in opposite directions. The vertical portions 42 are also provided with outwardly-facing rounded projecting ends 45 which, during the operation of the machine 3U, serve to form the projections or protuberances 21 which lock the cups I2 in engagement with the sash guides I I.

In order to accomplish this,y the machine 30 is mounted onthe bed- 46 (Figure 8) of a press or similar machine (not shown) having a verticallyreciprocating plunger 41 provided with a tapered lower end 48'.- The plunger 41 is of a small enoughA diameter to pass through the opening 23 in the cup I2, and its; tapered end 48 is inclined similarly to the bevelledy portions 44 of the horizontally-moving plungers 36.

In the operation of the machine 30 and the process of this invention, a cup I2 is inserted through one of the apertures I3` inthe sashguide II andthe latter is then inverted (Figure 8) with the flange 26 of the cup I2 resting on the rimV of the aperture 35I inl the' cover plate 34 of the machine4 36. The vertical portions 42y oftheA horizon-tally moving plun'gers 36 thus extend upward within the cup' I2 andA their outwardly-projecting ends 45 lie inl a1 higher level tl'ian the countersunlrA portions if surrounding the apertures I3.

'I-hey press isthen operated to cause the plunger 41 to move downward through the` hole 23 so that itsv tapered end 48- engages the bevelled portions 44' ofV the vertical plunger arms 42 and forces them apa-rtr (Figure 9). When the rounded ends 45 engagev the side walls 21| of the cup I2, they push these side walls 2| outward, forming the projections or protuberances 2-1. While this is occurring, the-rimof the-aperture I3 serves as an abutment to prevent the adj acentY portion of the cup I2 frombeing likewise forcedoutward.- The result is that' the protuberances 21 firmly lock the cup I 2 to the sash guide I I, with the countersunk portion I-8 firmly locked between therange 2li andi the projectionsor protuberances 21. The plunger 41 is then retracted upward (Figure 8),

whereupon the coil springs 38 return the plungers 36 to their positions in engagement with the stop 40, and permit the assembly I0 of the cup I2 and sash guide II to be withdrawn from the machine 30.

Since it is contemplated that the projections or protuberances 21 will be `formed in pairs at diametrically oppositev positions inthekside walls 2l of the cups I2 (Figures 1, 3 and 4), the ends [55 of the vertical portions 42 of the plungers 36 are preferably bifurcated or in pairs in order to produce two protuberances 21 simultaneously side by side,

The inodiiicatiri shown in Figure 10 employs a cup 50 similar to the cup I2 used in the form of the invention shown in Figures 1 to 9 inclusive, but the sash guide 5I has an inwardly-extending cylindrical iiange 52 forming a cylindrical bore 53 in place of the aperture I3. The diameters of the bore 53 and cu'p 50 are so chosen that it is' necessary t'o employ a considerable pressure to force the cup 50 into the bore 53 with the" c'up flange 54 resting against thefcontersunk portion 55 of thesash guide 5I. This press ,iitv of 'the' cup 56 with the iian'gge 52' of theL sash' guide 5I is preferably accomplished in a conventional press (not shown) of any'y suitable type. The cup .56 is thus held by frictional engagement with the flanged portion 52 of the' sashqguide 5I.

The' modification shown in Figure 11 is somewhat similar to that showfn in Figures 1 to 9 inclusive in that the cup 66 is held in engagement with the sash guide 6I by' pushing the side walls 62 of the cup 66 outward. In place of the projections 21, however, an annular projection 63 is formed on the opposite side of the countersunk portion 64 from the cup iiange 65. This may be accomplished by making the projections 45 of the machine 30 (Figure 8) of semi-circular form so that the two halves in assembly form a circular die, the halves of which are forced outward by the plunger 41, thus forming the annular projection 63, The operation of forming the annular projection 63 is otherwise similar to the operation of forming the projections 21 as previously described, hence requires no duplication of description.

In the modification shown in Figure 12,v the cup 16 is united with the countersunk portion 1I of thesash guide 12Y by crimping the iiange 13 of the cup 16 around the outwardly-flanged portion 'I4 surrounding thel aperture 15 into which the cup 1I)v is inserted. In this modication (Figure 1-2) ,the crimping operation causes the outer portion 16 of the ange 15 to be turned outward parallel to the countersunk portion 1I, and the edge portion 11 of the cup ange 13 to be turned rearward around the edge of the outwardly-extending portion 16 and withits rim portion18 tur-ned inward aroundthe same portionA 16. The above-mentioned iiange portions 13 and 14 are therefore interlocked with an overlapping grip, this likewise being done in a crimping die (not shown).

What I claim is:

A sash guide and cup un-t for receivingy a fastener securing said unit to a window frame, said uni-t comprising a sash cup having anlannular edge flange and a substantially at bottom with a hole therein for receiving said fastener, and an elongated longitudinally-grooved sash guide member having an aperture in the grooved portion thereof of substantially the size of said cup andhaving a countersink surrounding the edge of said aperture, said countersink having a width and depth corresponding respectively to the width and thickness of the cup edge ange, said cup being disposed in said aperture with its edge ange sea-ted in said countersink, said cup having a plurality of outwardly-projecting protuberances disposed across from one another adjacent said sash guide and on the opposite side of said sash guide from said countersink and ange.
