To all 'whom t may concern:

Be it known that we, Loma LELONG and JoranY Roscoe w, citizens of the United States, residin at'Newark, in the county of Essex and tate of New Jersey, have invented new andY useful llmprovements in Crumb-Collecting Devices, of which the following is a speciication.

The present invention relates to a device for the sweeping upA or gathering of bread crumbs and the like from the table after dining and embodies special features of ar rangement and construction whereb. itis particularly adapted to be made up o silver or other high grade metal as a part of the table service.

Desirable features of our improved device consist in a compact arrangement of the operating parts so as to occupy the minimum of space and wherein thebearings are inclosed entirely within the casing; .the arrangement whereby the collecting pan is pivotally supported upon the counter shaft in a manner permitting it to be swun back within the casing and wherein its fu cruin is removed from a position where it would be liable to catch in the table cloth; a par`- ticular form and arrangement of collecting pan affording a rearsupport for the device and a desirable tained wholly within the casing so as to preserve the desired unbroken exterior surface for the casing. These and other features of our invention will be understood from the accompanying drawing wherein the reference characters of this description are applied to like parts in the several views.

ln the drawing Figure 1 illustrates an embodiment'of our invention partiallyv in plan and partially in horizontal section; Fig. 2 is a cross-sectional view thereof; Fig. 3. is a perspective view of the saine and Fig. d is an enlarged partial cross-sectional view better to illustrate the detail of the collecting pan arrangement. u

In the figures, 1 indicates a suitable casing for the operating parts which may be of the design and substantially shown and desirably is of silver or other precious metal and to which is attached, preferably rigidly, the handle 2. lln suitable bearings d-t and 5-5 preferably arranged entirely within the interior of the casing there are journaled the respective shafts 6 and 7 The forward shaft 6 is the driving shaft and has fined thereon at its opposite Y l1 of cylindrical forin catch therefor also con-Y front edge of the size .f

ends, but within the casing, wheels or rollers 9--9.

Journaled on the shaft 6, between the wheels 9, is the hub 10 of the rotary brush as shown. To rotate the brush there is provided a pinion 12 fixed to the inner surface of one of the drivewheels, the left as here shown, to engage a pinion 13 fixed on the rearward or countershaft 7. 0n theopposite end of shaft 7 is secured a pinion 1'5 in mesh with the pinion 16 secured directly to the hub 10 of the the drivingbrush. Thus the movement of the driving l wheels 9, as `when they are rolled upon the table surface, will be transmitted to the brush l1 whereby it is rotated. The rotation of the brush desirably is at an increased speed, for example double the speed of the wheels as here provided for by reason of the driving pinion l2 having twice the diameter of'that of the pinion 13; pinions 15 and 1by being shown of the same size. X

rllhe rotation of the brush in the embodiment here disclosed will be in the direction whereby the lower part thereof will move rearwardly so as to brush the crumbs into a collecting pan 20 arranged at that side. The pan as here provided preferably is of the form shown having at its ends upwardly extending ears 21-21 apertured and fitted to the counter-shaft 7 whereby the shaft forms the bearings for the pan upon which it swings in the manner best illustrated in Fig. 4. As there'shown the pan is formed with a lower flat surface adording a good sliding surface to restupon the cloth and the pan in its operative position, shown in Fig; 2, forms the rear support for the device; the gupgort at the `front being upon the wheels The casing 1 at its front portion desirably is concentric with the brush and elevated from the cloth by the wheels at its lower sufficient to give a good clearance for the passage thereunder of the crumbs to be picked up. At its rear portion the casing preferably is formed concentric with the shaft 7, as likewise is the rear portion of the pan 20 which desirably is arranged to have a sliding fit within the casing'so as to permit of its being swung backwardly as shown in Fig. t to permit of emqllotying its contents when desired.

' o retain the pan in lower operatin position we have devised a simple and e cient yieldable catch desirably formed by slittin pan inlower operatlve position. The comsurface of the casing,

pressible catch so formed is simple and effective, having no detachable parts and, moreover, is adapted to operate totally within the casing so as to have no protruding parts and preserves the unbroken exterior particularly desirable in an article of this type.

An inturned lian e 20' at'the front edge 0% the an and t e front edge as shown isvdesirab y curved slightly upward tobe immediately adjacent to the brush. The pan i'sconveniently forced back to empty by catching hold of its front edge vwith the finger and pulling rearwardly to overcome the yieldin -sprin 23.

The bearings 4 an 5 are esirably of the form best shown in Fig. 4 consisting of rectangular blocks or inserts fitted to comlemental recesses r formed in the casing mteror and held in position by the securing screws 26 whereby the parts may easily be taken out for cleaning or in the event of constructing the casing of thinner metal the recees 1b may be omitted.

We have thus produced a device particula'rlyadapted for the purpose intended, eliminating additional securing parts and bearings for the collecting panand wherein we have obtained a degree of compactness permitting it to be made up commercially as a high grade article of for instance silver or gold as a part of the table service, at the same time possessing the required utility.

Having described our invention, we claim:

1. A crumb collecting device comprising a suitable casing, drive wheels suitably journaled, a rotary brush journaled concentric with the drive wheels, Aa counter shaft arranged parallel to the brush2 driving connections on the counter-shaft 1n engagement respectively with the drive wheels and the brush whereby the brush is rotated from the drive wheels and a collecting pan pivotally i, casing to empty its contents,

may be rovided the counter shaft, a

supported on the counter-shaft to aii'ord a rear support for the device and adapted to Y be swung rearwardly within the case to empty its contents.

2. A crumb collecting device comprising a suitable casing, drive wheels suitably journaled, a rotary brush journaled concentric with the drive wheels, connections from the wheels to the brush whereby the brush is rotated, a collecting pan suitably jonrnaled to afford a rear support for the device and adapted to be swung upwardly within the a yieldable catch o erating between the pan and the casing or retaining the pan in its operative position and a handle on the casing.

3. A crumb collecting device comprising a casing, a drive shaft jonrnaled in the casing, driving wheels fixed on the drive shaft, a rotary brush journaled on the drive shaft, a counter shaft suitably journaled parallel to the drive shaft. a pinion at one end of the drive shaft and rotatively connected thereto, a pinion on the counter shaft in mesh therewith, a pinion at the opposite side of inion secured to the brush in mesh with said opposite pinion and a collecting pan arranged to the rear of the brush and pivotally supported on the counter shaft. 4. A crumb collecting device comprising a suitable casing, drive wheels suitably journaled, a rotary .brush suitably journaled, a counter shaft arranged parallel to the brush, driving connections on the counter shaft in engagement respectively `with the drive wheels and the brush whereby the brush is rotated from the drive wheels'and a col lecting pan pivotally supported on the counter shaft to be swung rearwardly within the case to empty its contents.

In testimony whereof we yhave signed our names to this specification in the presence of two subscribing witnesses.
