INVENTOR.
JAMES EDWARD DUGGAN ATTORN EYS Patented Nov. 28, 1944 f This, invention relates generally to paint mask structures [adapted during painting forplating leplerations to protect onle or more portions of constitutes a continuation-impart of my applilike to prevent paint ozfjplatingmaterial from Lcbntett i igtr pas irig onto the teeth er the gears, prisms, etc." whe a epainted pr plated. r l i O je f "thele'ssential objects of the invention i'sto provide a tcti ng "the teeth mentioned wi'thoiit in any way ii ei ang eneeasily applied to and removed, tojbe protected without mare Another; object is' to provide a mask that'is simple inb'onSti-uctio nd economical to manuraeture- 1 I Qth'erfobj ects, 1 advantages and novel details "of construction 'of' this invention will be made more apparent as this description'proceedsj especially when considered inebfinettten with' the accomp ny n d win wherein-T w rtiel e frompaint platingmateriaI applied t cone or more adjacent portions thereof, and
*other' portions of such articles mask" carame of -thoroughly prberir'ig wit the" pa nting or platingoperf ca tb siee j iay 18,19 l2\,bearing Serial PATEN OF e ammie, i I M i rainrmsk s'rnuo'ronn ,1 a I iuggan, Application'July 19, 1343,Seria1 N0.495,322f t jsoiai m rotor-165 i h he 2'! are relatively thick and constitute extensions of opposite sides of the body 'portion l2. Preferably such flanges 2B and 2| have sufficient depth'to reach opposite'sidesof 'the body l2 of thigear when the mask ishaipplied thereto and thuspreclude any paint or plating material entering thevspaces 30 between the teeth H of the gear from either side thereof.
Preferably the resilienton'e piece mask B is providedbetween the side flanges 20 and 2| with radially extending internal teeth 22 'for mating With the teeth I I oi the gear As shown, the
:side flanges -2p"and 2| incline or converge ini when the mask isapplied toithe gear.
wardly from the body portion l2 and are provided at their inner free edges with inwardly projecting- lateralfflanges 23 and, 24 respectively which ove rlap slijghtly theinternal teeth 22 of the-mask! Preferably the'teeth 22 of the mask extend between and are terminally connected to the converging side fiangesw20 and 2| respectivelyJTlius, theteeth 22 of-the maskare narroweror shorter than the teeth 'I I of the gear and are"a',dapted tobe stretched and placed under tension in surface to surface engagement with the working surfaces of the teeth ll of the gear 1 Inuse, the mask B may be appliedto the gear A b'y" first lifting either side flange 20 or 21 over Figurel is a fragmentary side elevation of a gear and amask embodying my invention applied thereto, with parts broken away and in section;
Figure 2 is a ,fragmentary inside edge elevation of the mask illustrated in Figure 1 and showing a transverse section therethrough;
and II are the teeth of a gear A that maybe used in any suitable capacity, for example in the tethl I of the gear while the mask is in 'ti1ted position i elative to thefgearv so that such -teeth I| may be received in the space between saidside flanges 20 and" 2I- andmaymegister with the spaces 25 between the teeth 22 of the mask. Then the mask B'is stretched from said "opposite sides of the gear. When the mask is in a governor for an airplane, and B is a mask embodying my invention for protecting the teeth II from paint or plating material applied to the body l0.
As shown, the mask B is in the form of an mask B is formed of resilient material such as rubber or rubber composition and is adapted to straddle the teeth H of the gear. In'this connection it will be noted that the flanges 20 and this operative masking position, the teeth 22 of the mask are stretched and under tension in surface to surface engagement with the working surfaces of the teeth H of the gear and thereby I will effectively cover and protect such surfaces.
when it is desired to remove the mask B from the gear A after the painting or plating operation, the mask may be tilted relative to the body of the gear until one side flange of the mask mating engagement with the teeth of said gear." 2. A mask for protecting the teeth at the pev riphery of a gear, pinion and the like from paint and. opposite ends of circumferentially spaced transversely extending teeth of a gear from paint or plating material applied to the body portion of the gear, comprising a resilient relatively.
elastic one piece solid annular masking element having an interior surface substantially less than the exterior surface of said gear so that said masking element may be fitted by stretching it under tension over the teeth of said gear, said masking element having laterally spaced annular flanges adapted to overlie and bear firmly against oppositesides of the gear when said element is fitted as aforesaid to prevent paint or plating material applied to the body of the gear f'rom contacting opposite ends of the teeth of said gear, said masking element being provided and plating material applied to other portions'of said gear comprising an annulussof channel cross section adapted to be stretched over the periphery of said gear and provided between'op posite sides of the channelwith teeth for surface to surface engagement with the teeth of said 'gear.,,
3. Means for protecting the working surfaces and opposite ends of circumferentially spaced transversely extending teeth of a gear from paint.
or plating material applied to the body portion of the gear, comprising a resilient relatively elastic one piece solid annular masking element having an interior surface substantially less than the exterior surface. of said. gear so rthat'said masking element may be fitted by stretching it under tension onto the teethof'said gear, said masking element having projections so spaced and of such depthand thickness-that when the masking element is 'fittedas aforesaid said projections will be squeezed into! snug, non-slip surface to surface engagement with the working surfaces of the teeth of said gear to prevent paint or plating materialapplied to the body of the gear from contacting said working surfaces, said masking element also having portions adapted .to overlie and bear firmly against oppositesides of the gear when the projections'ofsaid element are squeezed as aforesaid to prevent paint 'or,
plating material applied to the body of the gear from contacting opposite ends of the teeth of said gear and to cooperate with the projections of said element to, prevent paint or plating material applied to the fbody of the gear from entering the spaces between the teeth of said gear.
, 4. Means -gforprotecting the working surfaces between said annular flanges with circumferentially spaced transversely extending projections forsurface to surface mating engagement with the teeth of said gear, said projections being terminally connected to said annular flanges and beingof suchdepth and thickness that when the 'maskingelement is fitted as aforesaid saidradial projections will be squeezed into snug DQn-sli'p surface to surface engagement with the working surfaces of said teeth and will maintain the ane nular flanges firmly against opposite sides; of the gear, whereb the projections and flanges collectively will prevent paint or platingmaterialapplied'to the body of the gear from entering 1 the spacesbetween the teeth of said gear.
5, 'Meansfor protecting the working surfaces and opposite ends of circumferentiallyj spaced transversely extending teeth of a gear from paint or plating material appliedto the body portion of the gear, comprising a resilient relatively elastic solid annular masking element, having an interior surface substantially less than'the exterior surface of said gear so that said masking element may be ,fitted by stre tching it under-tension over the teeth of said gear, said masking element having portions adapted to be sq zed into snug non-slip surface to surface engagement .with the working surfaces of the teeth of said gear; and having other portions adapted to over,- lie opposite ends of the teeth of said gear when 1 the element is fitted as aforesaid to prevent paint or platingmaterial applied to. the body of the gear from contacting the ends and working urfaces of the teeth of, said gear. 4 a
