Claims.
This invention relates to improvements in wire guards, such as strainers for use in conjunction with roof leaders, vent pipes and drains in general where it is desired to prevent ingress into such pipes of foreign objects or materials which might dam or clog them; cages for use in confining birds and animals; and devices for preventing theft of electric bulbs and similar articles.
Guards of this character are usually composed of a number of wire ribs of suitable shape spaced apart equidistant from each other and retained against displacement by girthing bands to which the wire ribs are attached or by girthing wires woven around the wire ribs. The wire ribs of such guards usually converge at one end thereof to a crown ring and are attached thereto by being bent therearound. Various forms of such girthing bands or wires and crown rings are shown in patents to Smith No. 199,115, Drendul No. 380,873, White No. 511,388, Bennett No.
713,733, Levy No. 926,704, Renzulli No. 1,767,733
and Little No. 1,815,982.
Each of these prior disclosures have inherent disadvantages, either being of insufficient rigidity and strength, liable to come apart while in use,
or too diflicult or expensive of manufacture.
It is therefore a principal object of my invention to provide in a wire guard a strong, rigid, firmly fixed construction, yet one which may be 3 simply and cheaply manufactured.
Another object of my invention is to provide a wire guard which does not require separate girthing bands or wires for retaining the wire r ribs in spaced relation.
Another object of my invention is to employ wire ribs for a guard formed into means for retaining spaced relation between the ribs.
Another object of my invention is to provide a crown device for a guard which will obviate the use of manual labor in the attachment of the wire ribs thereto.
Another object of my invention is to provide a two part crown device for a guard having predetermined spacing for the wire ribs in one of the parts and interlocking means for joining the two parts together.
With these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the appended claims.
In the accompanying drawings has been illustrated a simple and preferred form of the invention, viz. in a wire strainer, it being understood however that no limitation is necessarily made to the precise structural details therein shown, but that changes, alterations and modifications within the scope of the appended claims may be resorted to when desired.-
In the drawings:
Fig. l is a top plan view of my improved guard in form of a strainer for leaders or vent pipes with portions thereof cut away in order to clearly show the construction;
Fig. 2 is a sectional view taken through 2-2 of Fig. 1 looking in the direction of the arrows, and shows in detail the crown device completely assembled and the manner in which each wire rib is retained in spaced relation with the next adjacent ribs;
Fig. 3 is a reversed view to that of Fig. 1 and is obtained by inverting the strainer;
Fig. 4: is a plan view of the outer member of 20 the crown device, and shows its form prior to assembly;
Fig. 5 is a sectional view of the outer member taken through 55 of Fig. looking in the direction of the arrows; 25
, Fig. 6 is a plan View of the inner member of the crown device prior to assembly;
Fig. 7 is a sectional view of the inner member taken through 'll of Fig. 6 looking in the direction of the arrows; and 30 Fig. 8 is an exploded view showing in section the outer member of the crown device, formed ends of two wire ribs, and in section the inner crown device member, all in position for assembly and fixed interlocking relation.
Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views: it) is the outer member of the crown device and is formed from a blank. Outer member Iil is provided with recessed annular groove H, a plurality of radially disposed spaced tongues 12, inwardly of the annular recessed groove M, and a central opening l3 having an extended rim l3. The inner member M of the crown device is also 45 formed from a blank and is provided with an extended rim IS in which is located a plurality of equi-spaced slots 6, a plurality of radially disposed spaced openings 47 inwardly of the rim l5 and a central opening 58.
Individual guard ribs 69 are formed from wire of desired cross section and are provided with a bent portion 20 at one end thereof as shown'in Fig. 8, and at approximately midway of the rib 5 length an offset portion 2| is formed of proper dimension and shape so that each of the ribs l9 will engage and space apart the next adjacent rib when a plurality of ribs are assembled together, as is best shown in Figs. 1 and 2.
To assemble my improved guard, a desired number of formed ribs H! are first interlocked together. The inner member I4 is then placed inside the ribs is with the ribs disposed in the slots l6 of the inner member and with the formed ends 20 of ribs l9 projecting through central opening l8 of inner member I4. The outer member H! is then placed over ribs l9 and pressed firmly into engagement therewith, the spaced tongues i2 and extended rim it of outer member l0 entering into spaced openings I? and central opening 58 respectively of inner member 14 and the extended rim it of inner member l4 entering into annular recess I! of outer member IE3. While the outer member Hi, the wire ribs l9 and the inner member hi are firmly pressed together, the ends 20 of the wire ribs l9 and the tongues l2 of outer member is are turned outwardly of the crown device and pressed into clamping engagement with inner member M as indicated at 22 and 23 respectively. If desired, ends 29 of ribs I!) need not be turned as indicated at 22 as it is obvious that extended rim !3 firmly presses the ends 20 of wires i9 into engagement with the edge of central opening 5 8 of inner member M.
It will appear from the foregoing description that I have provided a wire guard in form of a strainer having but three simple elements, viz. wire ribs, an inner crown plate and an outer crown plate. It is obvious that it can be cheaply manufactured and with the minimum of manual labor in its assembly. Notwithstanding the simplicity of my guard, however, it is pointed out that it is of strong construction and cannot come apart while in use. It will also appear that I have dispensed with girthing devices of the prior art and have provided guard ribs which retain themselves in spaced relation with adjacent ribs. It will be clear from the foregoing description that I have provided a crown device with predetermined spacing for the rib ends and the parts of which have interlocking relation.
It will also appear that while I have chosen a strainer for purposes of illustration, my improved guard is also an improvement in similar constructions such as cages, traps and theft prevention devices.
It is also obvious that the form as to outline of my improved guard ribs may be modified for any desired purpose and that the offset portion may be located at any point between ends of the ribs or that a plurality of such offsets may be provided between the ends of the ribs.
It will also be obvious to those skilled in the art that any of the well known forms of banding devices may be used for attachment to the ends of the guard ribs opposite to the crown device.
Having thus described my invention and pointed out the features which are new, what I claim is:
1. In a guard, a plurality of ribs, a crown device for receiving and clamping end portions of said ribs, said crown device comprising an outer member and an inner member and between which said end portions are clamped, and one of said members having a central opening through which said end portions are bent, the other of said members having an extended rim for entering into said central opening and wedging said end portions into firm engagement with the rim of the central opening of said member.
2. In a guard, a plurality of ribs, a crown device for receiving and clamping end portions of said ribs, said crown device comprising an outer member and an inner member and between which said end portions are clamped, one of said members having an extended rim with spaced slots therein for receiving and spacing said ribs, and the other of said members having an annular groove for receiving said extended rim.
3. In a guard, a plurality of ribs, a crown device for receiving and clamping end portions of said ribs, said crown device comprising an outer member and an inner member and between which said end portions are clamped, said outer member having an annular groove, a plurality of spaced tongues and a central opening with an extended rim therearound, said inner member having an extended rim with a plurality of spaced slots therein, a plurality of spaced holes and a central opening, the annular groove of said outer member receiving the extended rim of said inner member, the plurality of spaced tongues of said outer member extending through the plurality of spaced holes in said inner member, and said extended rim of said outer member extending into the central opening of said inner member.
4. In a guard rib, a straight portion, a curved portion, and an offset portion therebetween, said offset portion engaging and spacing apart a next adjacent rib when a plurality of ribs are assembled together, said straight portion of said rib eiIecting substantially a continuation of the curved portion of the next adjacent rib with which it is in engagement.
5. In a guard rib, a straight portion, a curved portion, and an ofiset portion therebetween, said offset portion engaging and spacing apart a next adjacent rib when a plurality of ribs are assembled together, said straight portion of said rib effecting substantially a continuation of the curved portion of the next adjacent rib with which it is in engagement, and said curved portion effecting substantially a continuation of the straight portion of the next adjacent rib with which it is in engagement.
