` 1 claim. (c1. 144-2s9) yThis invention relates to an apparatus for applying material to parts, and more particularly to an apparatus for uniformly gluingv parts together. I y I Y The strength of the joint of two wood parts joinedby gluing depends 'upon the uniformity of application of the glue between the'parts. In applying glue to parts by one of the well known methods, that is, by brushing, itis dii-heult, if not impossible,` to `apply` the glue uniformly throughout the `surfaces to be glued andwith suitable thinness tofform'a joint of greatest strength `and avoid an overflow of glue from between the parts. f
An object of the invention is to provide a simple, eiiicient andpracticalapparatus for applying material to parts. l j With this and other ,objects in view, the inventioncomprises an apparatus for holdin'gone part while predetermined quantities of glue are ,Vdeiinitel'y disposed upon another part at spaced positions lso that the placing of the seconder glue applied part to the held part, causing a definite relative movement of the parts to cause the glue to bevdistributed between the surfaces of the parts to formaunifo'rmjoint of greatest strength.` I i I I Other objects and advantages will be apparent frein the' followingfdetailed 'description when taken in 1 `conjunction with Fig. 1 is a top planview ofthe apparatus; Fig. `2 `is a side elevational view of the apparatus, portions thereof being broken away;
Fig.; 3 is` a perspectivefview of the` glue applying element, and
4 is a fragmentary perspective view illustrating two parts joinedV together.-V
Referring now to the "drawings, it will be noted thatfthe apparatus in general consists of a glue `applying means indicated generally at III and a holdingfmeans indicated generallyat II, both of `which are supported by a table I 2 having sup- `portinglegs I3. The glue applying means IIJ comprises a glue pot I5 ofany Asuitable type, for example, the conventionally electrically heated I type,-vmounted in' an aperture in the table I2 so that the `opening fin the glue pot will be positioned but a slight distance above the upper surface ofithetable. An elementl is constructed to remove from Vthe glue pot Idefinite quantities the accompanying the invention the central part I9 has reduced ends equal in contour tothe surfaces of the end parts I8 to be positioned in engagement therewith and joined thereto. These reduced ends 2Il` form vertical walls 2 I conditioned to lie flush with portions of the inner walls of the parts I8. Therefore, in order to form the most eiicient glued joint `betweenthe parts I8 and the part I9, the element I6 is constructed so as to apply predetermined quantities at spaced positions along the lower surfaces of the parts I8 and along the inner walls thereof distances equal tothe depth of the wall 2| of the part I9. The
element, therefore, is constructed of a plurality of glueapplying segments or members 24 provided with aligned apertures for receiving retaining members such as bolts 25 and spaced from each other predetermined distances determined by the width of washers 26 mounted upon the bolts 25 between the members. Each member 24 has a raised portion 28 adjacent the center of its upper surface, these portions being of any desired width depending upon the width of the inner surfaces of the parts I8 to be glued. The ends of these portions 28 are in alignment, as illustrated in Fig.` 3.
Means is provided for moving the element I6 into and out .of the glue pot I5, this means comprising an arm 30 having its lower end resting upon'` certain of the members 24, as illustrated I2 when raised out of the glue pot. The lever 33 'is pivotally supported, at 36, by a bracket 31 mounted upon the table I2, and has its other end operatively connected to a foot treadle 40 by a link 4 I The foot treadle is pivotally supported at 42 by a suitable bracket connected to a crossbar` between the legs I3 and is normally urged or glue I'I, which quantities of glue may be transferred to tend parts IB, which are to be joined to a central part I9. The `specific contour of the parts I8 and I9 is immaterial, but to illustrate into upper position to normally position the element i6 in the glue pot by means of a tension spring 43, the latter having one end fixed to the table while the other end is connected to the The holding means II is composed mainly of has an arcuately cut away portion 50 so that the element may be moved beyond the forward edge of the table without interfering with the operator. The element 46 is also provided with arcuately cut away portions or recesses 5| positioned in general alignment with similar recesses 52 ofthe element 41, providing space upon each side of the part I9 for the operator to grip the part and readily remove it and insert a new part in place. By viewing Fig. 2, it will be observed that the element 46 is slightly thinner than the reduced ends of the part I9, while the elementI 41 is slightly thicker than the thickest portion of the part I9. The purpose of these dimensions will be hereinafter described.
The element 41 is slidably mounted upon the upper surface of the table I2 and has its ends positioned in guideways 55. The means for imparting movement to the element 41 consists of a foot treadle 56 pivotally supported, at 51, by a bracket carried by the crossbar between the legs I3. A link 60' connects the treadle 56 to an arm 6I which is fixed to a shaft 62. The shaft 62,'as illustrated in Fig. 2, has its ends j ournalled in suitable bearings 63, 64 and 65 and supports spaced vertical arms 61 and 68 which have their lower ends fixed to the shaft. The upper ends of the arms 61 and 69 are pivotally connected to angular brackets 69, the latter being secured to the element 41 as illustrated in Fig. 1. Helical tension springs "I0, having their inner ends fixed to the table I2 in elongate apertures provided for the movement of the arm 61 and their rearward ends connected to the arms 61, provide means to normally urge the element 41 toward the elem-ent 46 and to normally hold the treadle '56 in upward position. A stop 12 serves two purposes, one to limit the forward movement of the element 41 when there are no parts I9 disposed between the elements 46 and 41 and to serve as a locating means for the parts i9 when disposed in place between the elements.
Referring now to the operation of the apparatus, attention is first directed to the fact that both treadles are normally held in their upper positions by their respective springs, normally positioning the glue` applying element I6 in the glue pot and normally urging the holding element 41 toward the element 46. The apparatus has been designed to hold two of the parts I9 at one time in order to increase production and decrease the effort of the operator in actuating the holding means. The rst step in the operation is to open the holding means by pressing downwardly upon the treadle 5B to move the element 41 away from the element 46 against the tension of the springs 10. While the elements are in this position the operator may readily insert two parts I9, simultaneously if so desired,
upon each side of the stop 12, the stop assisting spring 'I0 to cause movement of the element 41 to form a gripping engagement of the parts I9 between the elements 46 and 41. In the next step in the operation the operator having a part I8 in each hand, lowers thetreadle 4U to the position shown in solid lines in Fig. 2, causing movement of the element I6 out of the glue pot, taking with it definite and predetermined quantities of glue which rest upon the upper surface of the element I6 and also upon the end surface of the projections 28, the excess quantities of glue passing between and upon the outside of the members 24 and dropping into the glue pot. The operator at this time places the parts IB upon the element I6 in the positions shown in Fig. 3, their lower surfaces resting upon the upper edges of the members 24 and their inner surfaces engaging the end walls -of the portions 28 to receive therefrom the quantities of glue. The width of the members 24 determines the quantity of glue disposed upon the surfaces of the parts I8 and the spaces between the members determine the number and spacing of these quantities. Furthermore, with this means definite quantities of glue are disposed at spaced positions throughout the surfaces to be glued, these quantities being equal to assure equal application of the glue throughout the surfaces. The positioning of the glue pot with its upper surface adjacent the top of the table I2 enables the operator to rest his arms and portions of his hands upon the table so as to easily and accurately position the parts upon the element I6. In this manner the parts I8 and the element I6, if so desired, may be moved toward the glue applying position at the same time.
After the glue has been applied to the parts I8 the treadle 40 is released, allowing the spring 43 to cause the element I6 to be returned to the glue pot. -The parts IB are then placed upon the reduced ends 20 of one of the parts I9 so that the inner surfaces of the parts I 8 will engage their respective walls 2|. At this time the parts I8 are moved longitudinally to spread portions of the spaced quantities of glue over the unglued portions, causing a uniform application of the glue between the surfaces being joined, and finally positioning the parts I8 in close engagement with the element 41, which serves to definitely and accurately locate the parts I8 on the parts I9. This completes the joining of onepart I9 with two of the parts I8. The remaining part I 9 held between the elements 46 and 41 may have parts I8 joined at the ends thereof by carrying out the same steps of the method previously described.
When the apparatus is in use, denite' known quantities of glue are disposed upon definitely spaced portions of the surfaces of the parts to be joined to the part I9 and by placing the parts I 8 upon the part I9 the ist portions of the surfaces of the part I9 coming in contact with the spaced deposits of glue receive portions of these deposits and by relative movement of the parts I 8v and the part I9 other portions of these deposits are spread upon the unglued surfaces and, due to the fact that equal quantities of glue are disposed equal distances apart on the surfaces, equal portions of these quantities may be spread upon the unglued surfaces, equalizing the application of the glue throughout the surface areas being joined, thus forming the strongest joint possible by gluing, eliminating waste of glue, providing a neat joint, and eliminating the necessity of the removal of excess glue. The thickness of the element 46 permits movement of the parts I8 without the possibility of causing the deposit of glue upon the element, while the element 4l is of sufficient thickness to hold the part IB in place and serve as a stop for the parts I8 to be accurately brought into` position with the part I9.
The embodiment of the invention herein disclosed is illustrative only and may be widely modified and departed from in many Ways Without departing from the spirit and scope of the invention as pointed out in and limited only by the appended claim.
What is claimed is:
In an apparatus for use in applying material to parts, a container of material, a material applying means having a plurality of like rigid 15 members formed with sets of lateral upper material applying surfaces and rigid projections interposed singly between the surfacespof each set, said projections having rigid material applying end surfaces lying in a pair of spaced planes transversely to a plane of the lateral surfaces and extending above the lateral surfaces, and means to cause movement of the material applying means from the container to cause the said surfaces to remove quantities of material there- `from and deposit the quantities of material at denite spaced positions on adjacent lateral and angular surfaces of a plurality of parts.
