Referring to the drawings in detail, Figures 1 to 3 inclusive show a sash guide and cup structure, generally designated I 0, formed according to a preferred form of the machine and method of the invention, as consisting generally of a sash guide II having a cup I2 secured in an aperture I3 therein. The sash guide II is employed in windows having a sliding sash, and is secured to the window frame I4 by fasteners I3 received in the cups I2, only one of which is shown. The sash guide I I is roughly in the form of a channel member having a central groove It for slidably receiving the window sash, thegroove I6 being provided with side walls I! and a bottom wall I8, the latter, in turn, being provided with recesses or countersunk portions IS surrounding the apertures l3 (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 flange 20 will be flush 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 I 2 are preferably stamped out of sheet metal by means of dies, but may be formed in any other manner.

The sash guide I I on the opposite sides of the guide groove I6 is provided with front walls 23 and side walls 24. The latter terminate in bent portions 25 which engage the adjacent surface 28 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 II, the cup I2, after its insertion in the aperture I3, is provided with protuberances or projections 21 (Figures 3, 4, 5) which are formed by forcing the material of the side walls 2| outward behind or beneath the bottom wall I3 of the guide groove l6. As the sash guide I I and cups l2 are ordinarily made of metal this means and method of securing the two together is simple and effective.

In order to secure the cup I2 within the aperture l3 of the sash guide II (Figure 8) the assembly of the cup I2 and sash guide II is inverted and placed in a special forming fixture or machine, generally designated (Figures 8 and v9) with the bottom walls I8 of the guide groove I5 resting upon the upper surface or anvil 3| of the machine 33. The latter is provided with a base 32 having a recess 33 therein closed by a cover plate 34 which carries the anvil surface 3|.- The cover plate 34 is also provided with an aperture 35 of slightly smaller diameter than the diameter of the flange 23, so as to support the latter in the position shown in Figures 8 and 9.

Reciprocably mounted in the recess 33 is a pair of oppositely-facing L-shaped plungers 36, the horizontal portions 31 of which are urged toward one another by coil spring 33 abutting th end walls 38 of the recess 33. A stop 40 mounted in a slot 4| midway between the end walls 39 p1events the vertical portions 42 of the plungers 36 from touching one another and leaves a gap 43 between them. The gap 43 flares outward at its top (Figure 8) due to the fact that the inner edges of the top portions 42 are beveled oif 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 30, serve to form the projections or protuberances 21 which look the cups I2 in engagement with the sash guides I I.

In order to accomplish this, the machine '30 is mounted on the bed 46 (Figure 8) of a press or similar machine (not shown) having a vertically-reciprocating plunger 41 provided with a tapered lower end 43. The plunger 41 i of a small enough diameter to pass through the opening 23 in the cup I2, and its tapered end 48 is inclined similarly to the beveled portions 44 of the horizontally-moving plungers 33.

In the operation of the machine 30 and the process of this invention, a cup I2 is inserted through one of the apertures I3 in the sash guide I and the latter is then inverted (Figure 8) with the flange 2|! of the cup I2 resting on the rim of the aperture 35 in the cover plate '34 of the machine 30. The vertical portions 42 of the horizontally moving plungers 35 thus extend upward within the cup I2 and their outwardly-projecting ends 45 lie in a higher level than the countersunk portions I8 urrounding the apertures I3.

The press is then operated to cause the plunger 41 to move downward through the hole 23 so that its tapered end 48 engages the beveled portions 44 of the vertical plunger arms 42 and forces them apart (Figure 9). When the rounded ends 45 engage the side walls 2| of the cup l2, they push these side walls 2| outward, forming the projections or protuberances 21. While this is occurring, the rim of the aperture I3 serves as an abutment to prevent the adjacent portion of the cup I2 from being likewise forced outward. The result is that the protuberances 21 firmly lock the cup I2 to the sash guide II, with the countersunk portion I 8 firmly locked between the flange '23 and the projections or protuberances 21. The Plunger 41 is then retracted upward (Figure 8), whereupon the coil springs 38 return the plungers 35 to their positions in engagement with the stop 40, and permit the assembly Id 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 opposite positions in the side walls 2| of the cups I2 (Figures 1, 3 and 4), the ends '45 of the vertical portions 42 of the plungers 36 are preferably bifurcated or in pairs in order to produce two pro-tuberances 21 simultaneously side by side.

The modification 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 5| has an inwardly-extending cylindrical flange 52 forming a cylindrical bore 53 in place of the aperture I3. The diameters of the bore 53 and the cup 50 are so chosen that it is necessary to employ a considerable pressure to force the cup 50 into the bore 53 with the cup flange 54 resting against the countersunk portion 55 of the sash guide 5|. This press fit of the cup 50 with the flange 52 of the sash guide 5| is preferably accomplished in aconventional pres (not shown) of any suitable type. The cup 50 is thus held by frictional engagement with the flanged portion 52 of the sash guide 5|.

The modification shown in Figure 11 is somewhat similar to that shown in Figures 1 to 9 inclusive in that the cup is held in engagement with the sash guide 6| by pushing the side walls 62 of the cup Iifloutward. 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 flange 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, thu 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, the cup 10 is united with the countersunk portion 1| of the sash guide 12 by crimping the flange 13 of the cup 10 around the outwardly-flanged portion 14 surrounding the aperture 15 into which the cup 10 is inserted. In this modification (Figure 12), the crimping operation causes the outer portion 16 of the flange 15 to be turned outward parallel to the countersunk portion 1|, and the edge portion 11 of the cup flange 13 to be turned rearward around the edge of the outwardly-extending portion 13 and with its rim portion 18 turned inward around the same portion 16. The above-mentioned flange 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 process of securing a flanged fastener cup having a fastener hole in the bottom thereof in a corresponding aperture in a sash guide, said process comprising countersinking said sash guide around the margin of said aperture, inserting said cup through said aperture with the flange of said cup resting in the countersunk portion of said sash'guide, inverting the thus assembled cup and sash guide upon an abutment with the cup flange and the surrounding sash guide surface resting against said abutment and with the hole in the bottom of said cup exposed. and inserting a portion of an expander through said fastener hole in said cup bottom and deforming the opposite portions of the side wall of said cup outwardly on the opposite side of said sash guide from the side thereof containing said countersunk portion and said cup flange, whereby to lock said cup in said sash guide.
