UNITED STATES PATENT OFFICE.
MORIS M. BERGER, OE CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO DORIS P. BERGER,
0F CLEVELAND HEIGHTS, OHIO.
SPRING MOTOR FOR CLEANING APPARATUS.
Application filed February T0 all whom t may conce/m.:
Be it known that I, Moins M. BERGER, a citizen of the United States, and a resident of Cleveland Heights, county of Cuyahoga, and State of Ohio, have invented a new and useful Spring Motor for Cleaning'l Apparatus, of which the following is a specification.
My invention relates to spring motor for cleaning devices whereby a brush, or other wiper, or other means,- is operated over a surface to be cleaned.
The main objects of my invention are an efficient device for operating a cleaning apparatus, which device is light in weight, which eliminates high friction mechanisms, which is simplified to reduce the cost of production, in which all of the parts thereof are easily accessible and without disturbing other parts` thereof, in which the speed of power discharge is controlled, which can readily be stopped and started, and in which y the stop and start mechanism` is automatically retained either in the stop or in the start position Without any auxiliary locking means.
In many instances, as in automobile windshields, or in locomotive cabs, or in streetcar vestibules, as well as in numerous other instances, it is necessary, or at least desirable, that the windows be cleaned in case of a storm, either rain or dust storm, so that the operator or driver may be able to see what is ahead and avoid accidents.
Hand operated devices for such purposes are dangerous since the operator must release some of his attention from the control mechanism of his vehicle and apply it to the operation of the hand cleaning device; whereas the full and undivided attention of the operator should be directed toward the control of the vehicle, particularly in a storm at which time the hand operated cleaner must also be operated.
An apparatus which embodies the features of the present invention and eliminates manual operation is shown in the accompanying drawing in which Fig. 1 is a general perspective view of a spring motor and a windshield cleaner connected therewith, and Fig. 2 is an end view at 2 of Fig. 1.
Smiliar reference characters refer to similar parts throughout the views.y y
The spring motor shown in the drawing 8, 1922. Serial No. 535,071.
has a general housing composed ofthe rear wall 10, the front wall 11the subwall 12, and the spacers 13, 14, 15, and 16.
The walls 10, 11, and 12 are made of suitable material, are sufficiently cutaway to reduce weight, and are'provided with the necessary journals and other openings as will appear presently.
The rear wall 10 is suitablywspaced from the front wall 11 bythe spacers 14,v 15, and 16, all of which are provided with threaded ends and nuts 17, on each end, whereby these two walls are firmly held in proper relation to each other. I v
The sub-wall 12 is located some distance inside of the front wall 1.1 and is firmly held in proper relation to the walls 10 and 11 by the spacers 13 and 15 and the nuts 17 thereon.
. The power shaft 18Vis journaled .in the walls 10 and 11 and has collar 19 bearing againstthe wall 11 and also has thel square end 2() to receive a key or crank (not shown in the drawing) wherewith the mechanism can be wound up.
Upon this shaft 18 is mounted the ratchet wheel 21 andthe power gear 22, and the flat coil spring 23; all of which elements constitute the power-plant of the apparatus and is arrangedv similar to, and operates similar to, the power plant of a clock which is well known in the art and need no detailed description here. Y
The spring 23 is made suflciently strong to operate the mechanismand has one of its ends secured to the spacer 14 while its other end is operatively connected with the shaft 18 and the gear 22.
The gear 22 meshes with the pinion 24 on the intermediate shaft 25 which is jour- Inaled in the walls 1() and 11.
On this shaft 25 is mounted the gear 2G which meshes with the pinion 27 on the stop and start shaft 28 which is journaled in the walls 10 and 11.
. On this shaft-28 is mounted the gear 29 which meshes with the pinion 30y on' the second intermediate shaft 31 which is journa-led in the walls 10 and 11.V
On this shaft 31 is mounted the gear 32 which meshes with the pinion 33 on` the governor shaft 34 which is journaled in the walls 10 and 11. .l
The governor 35, in this instance a vane engage any on'eof the pins-36 when broughtv tothe stopk position shown in `the drawing.
The. gear 22 also meshes with the pinion 39 onV the crank shaft 40- which isjournaled inthe. walls 10 ,and 12.
On the outside of the Wall l12, the shaft 40 carries the crank 41 which isprovi'dedl with the crank :pin 42,. n
The yoscillatory .shaft 43 is journaled in the-Walls 10 and,v V12and carries, on the outside` of the. Wall 12 the crank 44 which is provided with the crank pin 45 and the throw of which is larger thanv the throw of the crank 41. The shaft 43 also carries, on its other. end, the block 46 from which the Wiper or brush-47 is suspendedrthrough the bar 48.
The link 49 fits over the crank pins 42 and 45. and connects the cranks` 41 and 44.
The holes 50; are provided for screws Wherewith the apparatus ma -befastened to the frame. of the Windshiel The apparatus as a Wholemay be inclosed in'A a case,` preferably of light 'weightconstruction.
Thegeneral .operationo'f the power plant shown .here is similar tothe operation of the power plant of a Clock. c In" order tofprevent thespr'ng from un` winding .at a rateoi speed toO high for vthe purpose in hand, theQgove'rnor, mechanism is introduced and is operated .by ai train of gears, although friction Wheels, :or other drive means? may be employed,l theobject being to` control the speed'o'f the motive power release. Y
In the present instance, the vanes of the governor revolve at a comparatively f'high rate of speed due t0 the` highk ratios vlrtvveen 4the gears andl thereby limit lthe revolutions of the gear- 22. v
-Since it is notneceSsary to operate .this apparatus continually, andsifnceV this appa,- ratus shouldbe Wound up at all' times .and ready'for immediate use, the stop and start mechanism isprovided. Thedrawing shows the hook 38' of the lever 37 engaging.' one of they pins 36 whereby 'theentifre mechanism iS prevented from operating. lff'it is desir-edf tc. Start the. mechanism, Push the lever 37 in the direction of theV arrow ',*Whereupon the hook 3 8. will. dsengegethefpn 'Boland the gears and shafts are free to rotate. The
'This oscillatory .motion ofthe Shaft' 43 produces .a similar motion in the block 46 and, consequently, in the Wiper or'brushmechanism'cau'sing thesame to sweepvback ancljforth overv the. glassV 51 ofthe windshield `52v in an arcuate ,ath 53- It will be .seen that ft e present invention provides an, efcient, Self-ccctancfh; and effcctirey Power unit, v'Whiclllcoll readily "be ep.- p.1ied, either.' temporarily.
