WOODWORKING-MAGHIN E ATTACHMENT.
Application filed May s, 1928. Serial No. 276,069.
The present invention relates to an attachment to a wood Working machine and has for its principal purpose to provide a structure which will assist greatly in the making of molding and the like.
A number of devices used up to this time, are fastened to the spindles, and consequently any vibrations in this spindle affect the It is the object of the present invention to provide a rigid collar against which the piece of wood rests, thereby eliminating vibration and consequently the molding is made uniform, this with safety to the operator, who can use whatever pressure he desires against the rigid collar, without being in danger of slipping into engagement with the knives on account of the use of a movable collar.
Another very important object of the invention resides in the provision of a rigid collar through which the spindle rotates, and means whereby therigid collar may be supported in any desired adjusted position, so that the knives may be disposed thereabove and therebelow.
Another very important object of the invention resides in the provision of a gauge which will function to place proper pressure invention resides in the provision of an imon the work and which is thoroughly adjustable to accommodate the size of the work and other incidental peculiarities thereof.
A still further very important object of the provement of this nature whichis exceedingly simple in its construction, inexpensive to manufacture and embody in the usual woodworking machine, strong and durable, compact andconvenient in its arrangement of parts, easy to manipulate, and thoroughly efficient and reliable in operation.
With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides incertain novel features of construction, and in the combination and arrangment of parts as will be hereinafter more fully described and claimed.
In the drawings:
Figure 1 is an elevation of the attachment embodying the features of my invention. 7
Figure 2 is a top plan View thereof.
Figure 3 is a vertical longitudinal section therethrough.
Figure 4 is an end View of the adjustable bracket for the guide and guard.
Figure 5 is a top'plan view of the rigid collar. Y
Figure 6 is'a sectional View, taken substantially on the line 66 of Figure 3.
Figure 7 is a perspective view ofthe rigid collar. V a
Figure 8 is a perspective view of oneof the keys.
Referring to thedrawings in detail, it Will be seen that the numeral 5 denotes the bed of heights on the standard. The arm termi-g nates at the other end, in a pair of diverging fingers 16. A collar 17 has portions receiw 'able'between the fingers 16 and attached thereto by means of screws 18. This collar 17 may be formed in different sizes and may be disposed as shown in Figure 3, so as to extend partially down into the opening 6 or may be disposed considerably above the opening, obviously bymeans of the adjustment afforded by means 15 and set screw 14: for holding the collar 12 in different positions on the standard The spindle 7 extends through the collar 17 as is clearly illustrated in dotted line's in Figure 3. 7
An arcuate guard 20 may beconst'ructed of wood or' the like and has a pair of rods 21, secured as at 22, to the ends thereof and extending spaced parallelism as is shown in Figure 2.
A collar 23 is adjustably mounted on the standard 9 by means ofa key 24 and a set screw 25, and has arms 26 inclining downwardly and outwardly therefrom and terminating in sleeves 27 for receiving the rods 21, and set screws 28 are engaged in the sleeves for engaging the rods 21, for obvious adjust ment, to locate the guard means 20 in relation to the work and'the spindle. A collar 28 is adjustably mounted on the upper end of the spindle 9'above the collar 23, by means of a key 29 and a set screw 80. threaded rod 31 is disposed through a threaded aperture 32 in the collar 33 and has swivel connection 34, with the collar 23, and has a crank 35, for operation thereof.
The collar 17 is supported in a rigid or stationary manner, but may be adjusted as desired. This collar does not touch the spindle upon which the knives are attached. These knives may be fastened above or below the collar. The spindle revolves through the center of this collar. With this rigid collar against which the piece of wood may rest, there cannot be any vibration, and conse quently,-the molding or the like will be uniform throughout its length and it will be a saferope'ration for the operator who can use whatever pressure he desires against the rigid collar, without being in danger of slipping into the knives on account of the use of the movable collar as will be readily seen is a great danger in the common practice.
It will be further seen that the guard 20 may be placed down against the work, such as the molding, to prevent undesirable vibration, and at the same time, this guard prevents the hands of the operator coming in contact with the knives. The guard 20 is obviously readily adjustable. Major ustments may be made by the set screws 25 and 30. The set screw 30 is tightened first and then a micrometer adjustment is provided by the shaft 31 and then the set'screw 25 is screwed tight, so as to prevent unnecessary vibration.
It is thought that the construction, operation, and advantages of this invention will now be quite apparent to those skilled in this art, without a more detailed description thereof.
The present embodiment of the invention has been disclosed in detail merely by way ofexample, since in actual practice, it attains. the features of advantage enumerated as de- 'tages.
