ATTACHMENT FOR MILK-PAILS.
Specification of Letters Patent. Application filed May 20, 1912. Serial No. 698,472.
Patented May 20, 1913.
milk pails and, more particularly, it is directed to a simple and etlicient device for holding a strainer in position across the open top of a milk pail.
The principal object of my invention is to provide an attachment for milk pails, of
simple design and make-up, and which may.
beproduced at a low cost, whereby such attachments may be sold for little money.
Reference is to be had to the accompanying sheet of drawings, forming a part of this specification, in which similar charactors of reference denote corresponding parts in all the views, and in which- Figure 1 is a side view of a pail with the attachment in operative position; Fig. 2 is a perspective viewjof the attachment; Fig. 3 is a perspective view of a modified form.
Any suitable and desirable milk pail 10 has the filter cloth or strainer 11 held over the open end thereof by' means of the attachment which may be denoted as awhole The attachment preferably comprises a single strip 13 of resilient material,--preferably of uniform thiclmess and width throughout its length. Extending laterally from one side of this strip are a number of hooks 14, each of which is made up of the shank 15 and the overturned ends 16 are all adjacent the same side of the strip so that, when the same is brought to curved form, as shown in Fig. 2, theywill lie on the inside of the circle described by this strip.
Referring particularly to Fig. 2 it will be noted that the ends of the strip 13 where they come adjacent each other are bent outwardly, as at 20, in order to form a con venient gripping means for taking-hold of the attachment; it is also desirable that,-in
order to render the device most eflicien't, the
intermediate portion of the strip 13 be, of
overturned end .16. The
extending upwardly from the greater width than the thereof. I
The use of the device is apparent" fro-m Fig. 1, it being noted that the filter or strainer 11 will be held in position by means of the resilient strip bearing against the outportions to either side side of the pail, the position of the attachment being insured by reason of the hooks which engage the top edge portion of, the pail, such hooks also assisting in holding the filter cloth.
N o particular means are necessaryto hold 65 the attachment in such position that pressure may be exerted against the outside of thepail as the inherent resilience of the strip 13 is sufficient for. the purpose.
Referring particularly to be noted that the band 13 is provided with a number of inwardly projecting points 21.
adapted to serve the same hooks 14 of the first form of the device, these project-ions being formed preferably by driving the material inwardly.
In this form of the attachment the device will be held in position on the pail when the filter cloth is stretched over the open top, by reason of the engagement of the projecting points of the attachment in the material of the filter cloth.
purpose as the Fig. 3, it will.
Either form of device is equally well adapted to serve the purpose for which it was designed, that is, to unsure clean milk and a sanitary means of receivingthe milk in a .pail.
Having thus described my invention, I
claim as new, Patent As a new article of manufacture, an attachment for holding a filter clothon a milk pail, comprising a single strip of resilient material having overturned ends lying ad acent each other, and a plurality of hooks said strip of material, the hooks being adapted to engage the edge portion of the pail.
In testimony whereof I have signed my name to this specification in the presence of two. subscribing witnesses.
