f l i Thisinvention relates to a retracting device for kneeling benches and more particularly to a device ,which is adapted to automatically carry a kneeling bench. into an cut-of-the-way` position,

after it has been used, and retain itin said posii ftionwhile not in use.f i

object ofthe invention is to provide a device which is operated by suitableV mechanismhaving novel advantagesl and which is quiet in its operation, durablein construction, and easy to operate. Further advantages and objects of this inven- ,tion will be more clearly understood from the following description and from the accompanying `drawingain which-1v lFigure l isa iront view of and the retracting mechanism therefor which embodies my invention..

, Figure 2 is an end view, in central vertical section online 2-2 of Fig. 1. i. Figure 3 is a similar view on line 3-3 of Fig'. 1 Fig ure l is adetail view-of the bumper used for my improved retracting mechanism. l rFigure V5 is an enlarged front view, partially in central vertical section, of the said mechanism. `Figurefi is an end View, in central vertical section, of a modified form of the said mechai Figure V'7 is'a. front view of the operating spring 'andjcasing 'therefor with the cover removed.

shown in the drawings, 5--5 denotes the sides of a pew'v bench having a seat 5 extending therebetween. `A kneeling bench 'l is normally positioned between seat' 6, and is` adapted to be moved into-position fiorA use-as clearly illustrated indotted Vlines in Figs. 2, f3 and 6. Thelmechanism for carrying said kneeling bench comprises a support that is preferably in the form of a casing 8 whichv is secured to one of the benchsides 5 and has a bearing 9 within whichis rotatably mounted a shaft l@ that extends through a spring winding drum Il having a notched adjusting ratchet flange l2. The said shaftis retained in position by means of a screw 'I 3Y which extends through the rear of the casing 8 and has a washer I4 fitting against a shoulder at the end of the shaft to permit'rotation thereof. l A'spring l5 is contained within the casing 8 with `its outer end secured to an abutment I6, in the casing 8, and its inner end secured in a groove Il in the winding drum ll. #f A bench carrying lever" i8 is secured to the shaft 'l and extends upwardly therefrom to a pivot I9 upon a bracketjZD-that is attached to the side of the kneeling benchleg 2l'. "Another lever 22Y is a kneeling bench l theA said sides 5--5, under the' 9 claims. (c1.v 155-156) 2 pivotedpat 23, upon the casing. 8, and extends therefrom to a pivot 24 upon the bracket 2B.

At the opposite end of the kneeling bench `lf and attachedto the leg 2,5 thereof there is a bracket `26-to which there is pivoted, at 21, a lever 28 which 'extends to a bracketvv 29 that. is secured to the Aopposite bench side 5, the lever 28 being pivoted by means of a stud 30. Another lever 3l ispivoted upon the bracket26, at 32, and extends to the pivot 33 on the bracket29.

Suitable bumpers 34-34 are secured to the sides 5--5 in positiontoabut the levers laA andz28 so as to stop the operationotne lifting'device and locate the kneeling bench in its retracted position. The said bumpers may be constructed as shown in Fig. 4, and comprise a frame 35 having a tubularporton 36 within whichnthere is mounted a: spring 31 pressing outwardly on a slidable button 38r which engages oneof the-levers 18u28.; 'f The tension on the spring Vl5 may be adjusted forthe weight of the kneeling bench, as may be desired, by disengaging a dog 38-a,` which -is pivoteki-to the-lever 8, from the ratchet l2, rotating thedrum Il until the'proper tension in the spring' is obtained, `and then; again engaging the' dog SEQ-a with the ratchet to retain the adjust;- ment. I t Y y fThe operationofthe invention-is asffollows:`

In its normal position, `the kneeling bench is located under the,` seat 6 as clearly shown in Figs. 1, 2, 3 and 6. When it is. desired to use the bench, it is simply swung downwardly, to the position shown .inV dotted lines `in Figs. 2 and 3. The parallel levers'lS and 22 andZS-.and 3l witl act to constantly retainthe bench in a vertical position and' as it'is carried from the retracted position' to the lowered' position for use, when the movement of the lever i8 will cause'winding of the 'spring l5'.

As long 'as there are persons. kneeling on the bench, it will remain in its downward position. When the last person arises, the spring I5, will act upon the' drum Il which` in turn will` rotate the lever I8 and raise the kneeling bench to its 'retracted position. As the bench reaches its retractedposition, the levers I8 and 28 will strike the bumpers 35 and the bench will cometo a stop without .causing undue noise which would be rather disturbing where many of such benches wouldbe operating at about the same time.

In order to further reduce noise from the operation of the said retracting device, I may, ifdesired7 providean air cushion at each side 5-5 of' the seat which cushion may be in the form of Y upon a bracket 4|.

kward movement of the lifting Y "rotatable infsaid casing and Y. gregation. The said air cushion also acts as Va positive stop,

when the plunger reaches the limit of its inward movement into thel cylinder 31, to

1 retain Vthe kneeling bench in its retracted position.

checking the up- Y 4 with said shaft and having its opposite end pivoted to a kneeling bench, a separate lever pivoted to said casing and kneeling bench parallel to the iirst lever, and means between the first lever and the ratchet for adjustably connecting said spring to said lever for operation of the mechanism to lift thebench from a loweredV position to a retracted position. Y

4. A device of the character described for lift- `ing a kneeling bench from a lowered position to a retracted position under a seat; said device comprising a mechanism having a casing mount- It may be found in some cases, and particularly where long kneeling benches are used, that 'When the said benches are the far end opposite the spring operating side of the retracting device, there willbe a twist in the bench, between that end and the opposite end,l

due to pull against the `resistance of the spring .I5 being' appliedV from the saidV far end of the bench; VInxorder to avoid this, I may provide a tierbar between the'levers- I8 and 28,' as clearly illustrated in Figsl and 5 of the drawings.

l 'The said tie bar may consist of a vtubular'bar 44 and may be secured at one end to the shaft I0 'by means of aconnectingsleeve 45 and at the opposite end to a hub 46 uponv the lever. 28. This barwill tie the two Yopposite ends of the retracting mechanism so that they' will operate together Vand thereby eliminate any tendency of the kneeling'bench to twist regardless of where the bench is grasped for m vement toits downward posi-f tion.:k Y .I-rclaimzf 'Y i A device of the character described for lifting'fa kneeling bench from a lowered position to araisedt position'where thesaid bench is Vretra'cted` under a seat, the said device comprising a mechanism including a casing mounted at the side fof said seat, a leverpivotally-mounted at onefend to 'said'casing and at the opposite end to the kneeling bench, a separate lever having one end pivoted at a point spaced from the-pivot of the Yfirst lever Ain the casing vand fits opposite end pivoted to saidbench at a point spaced from the first/lever, vspring means urging said levers to 'raise said'bench,Y and stop means for limiting the movement of said layers toV locate the bench in a retracted position under the seat.
