COMBINED SASH HOLDER AND STARTER.

Application fi1ed February This invention relates tocombined window sash locks or holders and starters,

where the starter member prys against the sill during the operation oi? the sash holding mechanism to withdrawthe locking bolt or member thereof and it has for its object,

particularly simple and ctlicient mcchanisnr by which the. sash starter member is member moved out of effective position at the end ot the operation of the sash holding mechanism, that is, when the bolt or other iocliing member is entirely withdrawn so that during the lowering of the sash, the sash starting member will be out of operative position and not engage the sill so that the window can be entirely closed as the sash starter is entirely out of operation until the operator again releases the sash holding mechanism, which he does only when the sash is closed, and it further has for its object, means whereby the sashstarter n1cm her can return to operative position in order to be ready to act to pry upon the sash after the sash has been once closed.

The invention consists in the novel features and in the combinations and construe tions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters represent corresponding parts in all the views.

Figures 1 and 2 are elevations or slightly different forms embodyingmy invention.

This sash starter and holder comprising generally mechanism including a manually operable element, a downwardly movable sash starting thrust member arranged in the path oi" the operating element. to be effectively actuated thereby during the initial move- 1 ment of the operating element, and means by which the starting member is relieved of ett'cctive thrust received ironrthe manually operable element, as the operating element approaches the end, of its throw by shifting one or the other of said parts. It further preferab y comprises means for automatically retijir ing the thrust member into effective thrusti'lw' relation during the return move Serial No. 165,513.

wise movement during the retrograde or re-' turn n'loveme ito'l the operating member to its starting position by cam means, which return it into effective thrusting relation.

in the illustrated embodiment of my 1nvention in which this sash starter mechanism is combined with one old form of sash holding mechanism or sash lock, the sash starting or thrust member is shittable relatively to the operating element out of effective thrusting position aswell as back into thrusting position, and is connected to the operating element or lever of the sash holder mechanism and moves therewith, and is normally in position to thrust against an abutment usually provided on the sill. It is shittable relatively to the operating element or lever out of effective thrusting relation by being shifted by cam means out of alignmentwith the abutment as the operating element approaches the end of its throw, and is also shifted back into effective thrust. in relation by cam means during the return of the operating element to its normal or starting position. However, I, do not limit my invention to shifting the thrust n'iembcr at an angle to its thrusting movement out 01 effective thrusting relation by moving it out of alignment with the abutment, as it may remain in alignment with the abutment, and operate into and out of efiect-ive relation with the operating element without departing from the spirit of. my invention. In other words more or less change may be made in the construction hereinafter described without departing from the spirit of my invention.

h'lore specifically the illustrated embodiment of this sash starter and holder comprises generally sash holding mechanism ineluding an operating element, a sash starter -ahle laterally at the end of the operating or withdrawal operation of the sash holding ll'lOClitIlllSlii, and means for shifting said sash starter member laterally out of alinement with the abutment at the end of the operating movement and for again moving it into bolt 4 suitablv guided in the has Patent No. 1,597,571 dated December 1925, although it may be combined with a y other form of sash holder or lock.

Sash. holder mechanisms are usually not. mounted direc y upon tic sash but are unitary structures and comprise a base which is mounted on the sash and this base is usually in the form oi? a housing; or casing.

1 designates the base, it being shown as in the form oi a casino; ora block formed with a recessQ opening; through its rear face or its face opposed to the sash, the base 1 being secured to the sash in any suitable inanner by screws 3.

The sash holding mechanism is spring pressed, That is, it is pressed into locking position by a spring, the sash holding mechanism here shown includes sliding looking a or casing 1 and having teeth 5 projecting out oi: the recess 2 in position to engage a rack or sinnlar device 6 on the window mine i. The sash holding mechanism also includes 2 n operating element, it being here shown a lever 8 pivoted within the casing at 9 and havingan arm 10 coacting with the bolt to withdraw it against a spring 11 when the lever 8 is actuated, this arm 8 also servil return the lever to its normal position under the influence of the spring 11. Q

p The lcrer o is here shown as a hand lever, it having a linger engaging portion 12 extending outside of the housing 1 and arrangi-id in jurdapm-ition toa grip or pinch handle 13 rigid with the casino, 1. The construction thusilar dc-- scribed is old and per se, forms no part of this invention, and any form ol sash holder or lock may be substituted therefor or in some cases it may be desirable to omit the sash holding feature.

14 is the sash starter ineniber movable downwardly against an abutment 16 which is here shown as provided on the sill It will beunderstood that the sill has two top surfaces at different levels and that the sash when closed, bottoms on the lower level. The abutment when on the sill on the up per level.

The sash starter is here shown arraug in the path of the lever S to be actuat thereby and as pivotally connected to the lever 8, and as niovable endwise downwardly through an opening 1? in the lower Wall of? the base or casing 1, and means is provided gagernent with the rack 6, that is when the handle l2 of the lever 8 is closed to the pinch handle Normally, the sash holdlever il thrusts against the abutment The abutment is formed with passage at one side thereof and this passage is most conveniently provided by having the abutment raised above the upper face of the top level oi the sill but it need not necessarily be so a it only necessary that it be so ar- 1' ed that the lower end oi the sash starter i ll can move past it downwardly member aeand ratchet over it upwardly, regardless oit whether or not the abutment is on the sill or some other part of the window frame. The abutment is here shown as the head of a screw.

In the illustrated enibodin'ient of my in ventioin the sash starter nieinber l t is a plunger pivoted at 1,8 to the lever S and depending therefrom through the hole 17, this hole slidably fitting the portion of the starter therein when the parts are in their normal position, that is, when the bolt at is engaged with the rack 6.

The nieans tor shitting the starter latorally out oi alincinent with the abutment it} at the end oi the operation of the lever is that is, after the belt 4 is withdrawn orn the rack 6, comprises cani ineans in i ing portions carried respectively by the or casing l, and by the inen'iber let and normally spaced apart and arranged. to ($01116 into action when the lever i approaches the end of its dowi'iward movement. As here illustrated, the case 1 is provided with a earn cur-time 19 adjacent the opening 17 and the member ll is formed with a projection 20 at side oi its pivot 1&5 and arranged. to can age the earn surface 19 as the lever 12 apiroarhes the end oi its throw and during snrh engagement the projection 52!) slides ao= g tire cam surface 19 and tort-es the starter member l-l laterally out of eitli'cctive thrusting position or out ot alineineut with the abutment l6. l i hen the operator releases the lever 1), the spring ll returns the sash holding nieclianisn'i to its normal position and thus pulls upwardly on the sash starter member 1% cousins it to return into alinenicnt with the sin inient to. it the sash is closed under the influence oi earn means to be presently described, the sash starter nieinber ll will 'ide or ratchet up on top of the abutment i6. The oi the starter member 1st permitted by making the portion 21 or said member adjacent the projection 20 of less diameter than that portion normally located in the opening 111" and the iact that the portion nori'nally in the opening 17 slid-ably fits the opening causes the starting member to shift on its pivot into alineinent with the abutinent during: the movement of the sash holdineehanisin to its lorinal position. By

lateral tilting I ll? forming the inner end portion of the starter member of less diameter than the lower por tion or by cutting out the upper portion of r the wall around the hole 17 during the upward movement of the starter member and thus forces or cams it from inclined to straight position as the lower portion of in the sash holding mechanism, an additional spring spring return spring 22 acts primarily to prevent rattling and takes up lost motion. Preferably, the sash starter member 11 has a reduced portion 23 at its upper end and shoulders as at the base of the reduced portion, the reduced portion extending between ears or lugs 25 on the lever 8 and being pivoted thereto by the pivot 18 The pivot is loose enough to permit the shoulders 2 1 to engage the lower ends of the lugs 25 when the lever 12 is being depressed so as to relieve the pivot of this thrust.

In Figure 2, a sash holding mechanism is shown with a slightly diflerent arrangement of starter member and in Figure 2' the starter 22 may be. preferably employed, this acting directly on the handle 12 to member 14* is shown as square in cross section and as pivoted at 18 to a single lug 25 on the lever 8*, the starter member sliding along the inner tace or bottom of the re eess: 2. Also, the spring 22flis shown as seated in a well 26 formed in the lower part of the casing. In Figures and 4-, the cam means corresponding to the cam means and the reduced portions 19, 20, 21and 200 and 201 of Figures 1 and 3 are designated 19, 20221 and 200 and 201. p

In operation, assuming that the sash is open, the operator normally engages the handles 12 and 13 ot the sash lock on each side of the sash and pinches the handle 12 toward the fixed handle 13, thus withdrawing the bolt 1 and shifting the sash starter ,member laterally out of alinement outh the abutment 6. Thesash is then closed so that the lower rail of the sash abuts against or bottoms on the lower level of the sill and owing to the fact that the operator holds the handles pinched together, the sash starter member is out of alineme'n't with the abutment 16 and passes to one side of said abut ment, so that the sash can come completely down against the sash. After the operator it to its normal position, but this lets go of the handle 12, it returns to its normal position and the bolt engagesthe rack and the lever 12 in so returning to its normal position carries the sash starter member 11 up so that its upper end rests on or is opposite to the abutment, the surface 200 :ausing the starter member 14 to move back into effective relation or into alinement with the abutment during the upward, movement of the starting member. 1

To raise the sash, the levers are again pinched together and a lifting force applied and during the withdrawal of the bolt, the sash starter member 1a presses downwardly against the abutment 16 and prys thesash oil the sill, this prying action being completed before the sash starter member is out of effective thrusting relation or shifted laterally by the cam parts 19, 20 coming into coaction as the lever 12 approaches the end of its throw.

This starter member is particularly advantageous in that the sash can be completely closed instead of only mearly closed as in sash starters heretofore used, and further in that when closing the sash no force or sting is applied to the operators fingei's due to the fact that the sash starter infringes the sill or the abutment on the sill.
