PAN- GREASING BRUSH Filed April 21', 1941 Inventor 7 A 7 JwwMVM/dv Patented June 15, 1943 UNITED STATE-s PATENT OFFICE- 2,321,961 PAN Gi tE- ASING BRUSH James M. Wilde, Philadelphia, Pa. Application AprilZl, 1941, Serial No. 389,657 Claims; (01. 15-128) The present invention relates to new and useful improvements in fountain brushes designed primarily for use in greasing baking pans and the like, and has for its primary object to provide a brush of this character adapted to more effectively enter the corners of the pan for properly greasing the same.

A further object of the present invention is to provide a brush mounting including a substantially conical cap having a plurality of brush sections mounted therein adapted for engaging the bottom of the pan, the brushes projecting'in diverging relation and adapted for spreading into the corners of the pan when the pan is placedin position on the brush, and also to provide means for easily and quickly detachably securing a plurality of brushes on the brush mounting for wiping. against the side walls of the pan during the greasingoperation. A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

,Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a side elevational view,

Figure 2 is a similar view with the side brushes removed and with the cap detached from the mounting,

Figure 3 is a bottom plan view, and

Figure 4 is a top plan view.

Referring now to the drawing in detail, where- ,in for the purpose of illustration I have dis- 'closed a preferred embodiment of the invention, the numeral 5 designates a brush mounting generally which includes upper and lower brush supporting plates 8 and 1 respectively, connected by a grease feed tube 8. The peripheral edges of the plates 6 and l are provided with alined slots 9 disposed vertically and adapted for receiving the substantially rectangular-shaped brush heads Ill with the bristles ll of the brush projecting radially from the mounting and extending in a vertical position.

The brush is preferably constructed with three sets of the vertically extending brushes l0 and the brushes are connected by a coil spring l2 to yieldably maintain the heads of the brushes in the slots 9.

On top of the plate 6 is a conical cap I l3- pr0- vided with a short pipe l3 fittedin the upper end of the tube 8 and secured thereto by a set screw l3", the cap being preferably constructed of a plastic material and within which three sets of bristles M are embedded, with the bristles extending substantially at right angles to the surface of the cap and with their outer ends in diverging relation. Likewise, the outer ends of the bristles taper into a substantially pointed extremity as indicated at Hi. The sets of bristles l4 likewise are positioned between the vertically extending brushes I0.

To the under side of the lower plate is secured a socket l6 adapted for connection with a grease supply pipe (not shown) the grease being forced under pressure through the tube 8 and outwardly through the pasage ll formed in the top of the cap l3. Likewise the surface of the cap I3 is formed with channels I8 leading from the passage ll toward the vertical brushes H).

In using the device, the bread pans are placed over the brush assembly, thus causing a spreading of the brushes l4 against the bottom of the pan and into the corners thereof. At the same time, the vertically extending brushes Ill serve to wipe against the side walls of the pan and by arranging the brushes H1 in substantially triangular form in cross section, as shown to advantage in Figures 3 and 4 of the drawing, the bristles ll of the brushes Ill are adapted to also enter the corners of the pan to efiectively grease all portions of the pan.

The loose mounting of the brushes Ill in the slots 9 enable the brushes be easily and quickly removed and replaced when desired.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having'thus described the invention, what I claim is:

1. A pan greasing brush comprising a mounting having a conduit extending therethrough, one end of the mounting being adapted for attaching to a grease supply pipe and the other end of the mounting having a grease discharge port, a plurality of groups of bristles secured in diverging relation to the mounting at its end adjacent the discharge port sockets at circumferentially spaced points on the sides of the mounting and a plurality of brush units secured in said sockets, said brush units extending longitudinally of the mounting and projecting radially therefrom.

2. A pan greasing brush comprising a pair of circular plates, a grease feed tube connecting the plates in spaced relation, means carried by one of the plates for attaching to a grease supply pipe, a cap on the other plate having a discharge port communicating with the tube, outwardly diverging groups of bristles secured to the cap, alined sockets in the edges of the plates and brushes having heads removably positioned in said sockets;

3. A pan greasing brush comprising a pair of circular plates, a grease feed tube connecting the plates in spaced relation, means carried by one of the plates for attaching to a grease supply pipe, a cap on the other plate having a discharge port communicating with the tube, outwardly diverging groups of bristles secured to the cap, alined sockets in the edges of the plates, brushes having heads removably positioned in thesockets and spring mean said brushes.

connecting the heads of 20 l. A pan greasing brush comprising a pair of circular plates, a grease feed tube connecting the plates in spaced relation, means carried by one of the plates for attaching to a grease supply pipe, a conical cap of plastic material carried by the other plate and having a discharge port communicating with the tube, a plurality of groups of bristles projecting from the surface of the cap in diverging relation and a plurality of brushes attached in spaced relation to the edges of the plates. i

5. A pan greasing brush comprising a core "having a feed passage therein for discharging grease at one end of the core, brush units projecting in diverging relation at said discharge end of the core and brush units extending longitudinally at the sides of the core and arranged in triangular cross-sectional relation with respect to the core and longitudinally between the firstnamed brush units.
