y Application filed August 5 1926, Serial No. 127,238; V

This invention relates to cushions'fo'r sprinkler heads, and is more particularly directed. to an attachment for sprinkler heads constructed of a material softer than the sprinkler head and Which'ls adapted for y V V A ters throughout the' entire area of the field'` use yon athletic fields, parks,pand the like.

In the maintenance of turftyfi'elds Wherey athletic games, suchfas football,lbaseball, golf, and the like, are played,the turf re-- quires a relatively large amount of tvater', been found` can most efliciently y.be suppliedy by means ,of a sprinkler. system permanently mounted infposition on the field. These athletic fieldsA aresubject yto great Wear, and toginstall sprinkler heads for giving the same the desired or required amount of Water, it hasbeenfound that exposing the metal heads at the surface of the turf, that in playing football, or like games, y

lthe player is apt to be seriously injured thereby. It is, therefore, yan object of this invention to provide a cushion attachment for the sprinkler heads Which is constructed of relatively soft material Which Will pr'otect the player from .the metal heads.

Another object of this invention is to provide a cushion forsprinkler heads adapted to cover the top of the sprinkler head and having an orifice formed therein corresponding to the sprinkler head orifice. f

Another object of this invention is to provide a cushion attachment for sprinkler heads Which is adapted to'bemounted on the top of the Vsprinkler head and Which has a beaded portion ofless diameter than the rim of the sprinkler head. Other objects and advantages of thisin'- vention Will be apparent from ythe following detailed description of a preferred embodiment thereof, as illustrated in the` accompanying drawings. f

In the drawings: Figure l diagraminatically illustrates the positioning of sprinkler headshaving cushon attachments embodying this in'ventiony mounted in position in an athletic field.

Figure 2 is a top plan View of the cushion attachment for *sprinkler heads embodying this invention, f

Figure 3 is a side elevation thereof.y Figure 4 is a. central Sectional side elevation of a cushion attachment embodying .this invention. f r

Figure 5 is a perspective view thereof.

In the preferred embodiment of this` invention, illustrated in the accompanying 1 1117,709 PTIENroFrios;

.'draivings, 1h illustrates an athletic. field,

Whicli is hereinillustrated asof` the type employed in playing football, yand on which `field' sprinkler vheads 2'are mounted in staggered relation on* approximately 12 ft. cenand are connected' With any suitable or desir- The sprinkler lieads 2 arenof anydesired or ypreferred construction and are herein illustr'ate'd as comprising a bodyy3 having a H rim 4 formed' at theirupper enld.` A central orifice 5 is formed through the body 3.1

The cushion 6 embodying this invention is preferably ,formed of a soft material such,

for example, as vulcanized .rubber or the like andV in the form herein illustrated has V y i a doWnWardly lextending circumferential fl'ange 7 of lessinterior diameterthan the rim 4 and the sprinkler head 2 is adapted to fit over the rim 4 of the body'Q, and in- Which yflange `7 a circumfereutial groove 8 is formed, into Which the rim 4 is adapted to fit. The cushion 6 has an opening or orifice 9 formed in thecenterthereof or formed in position Vto correspond With' the orifice 5 7 formed in the body 2.

The cushion 6, as illustrated in the draW- y1ng,vcomprises a taperedy inner surface 10, taperi'ng outwardly from Vthe orifice y9,' the material' ofwhich .the cushion fis formed terminating at substantially'an edge, 'as illustrated at 11, overthe or'ifice 5 of the body 2 so as to prevent the passageiof Water into ythe interior of the'cushion 6. The cushion .6 -1s cut avvay at a circumferential groove 12 on the interior thereof so that the edge llfivill engage the top Vsurface ofthe body 3 of the '160 f sprinkler head V2. V

In forming the cushion 6 foruse on fair- Ways Vofgolf courses, theV body of the cushion 6 would preferably be formedjstraight across, eliminating the tapered surface 10 so as to preventlthe lodging ofy the golf ball therein. The cushion When used on golf courses is particularly useful in` shielding the'sprinkler head 2 from the blows ofy the golf yclub sozasto save not onlyfthe golfy clubs but ythe sprinkler heads.

Having Vfully described a .preferred embodiment ofmy invention, it is to be under-V 'lie V Svzoody that-I doV not wish to beiimited a; the

exactV details therein set fort'h, VWhich may obvously be vared Without departing from i the Vspirit of my invention as set for'thin' the appended claims.

I claim: V 1. The combination With a sprnklerhead,

\ having a circular flange, of a cnshon adapt'ed vto be mounted on the sprinkler heada'nd having a downwardlyextending flange for, VSecurmg the Cushlon toV said sprinkler head flange, the cushon having-an axialy orifice,

a and V'the upper surface of 'the ycu'shion being fiared outw'ardlyfrom the orificeto permit Water to be throWn in a spray directly from the orificev of the sprinkler head.

2. The combnationwtha sprinkler head,
